Introduction
0.1
General
For the purpose of this document, multipoint radio systems may be defined as radio systems which interconnect a
number of fixed stations (usually more than two). The topology of the systems may be point to multipoint (P-MP), or
multipoint to multipoint (MP-MP), or a combination of the two. MP-MP is alternatively known as "mesh". A variety
ETSI
7
DEN/TM-04130-1 v0.0.2 (2003-03-25)
of technologies for multiple access and duplex communication is used. The application of these systems is primarily,
but not exclusively, to provide access to a variety of services employing a wide range of bit rates. This application is
frequently referred to as Fixed Wireless Access (FWA). An alternative application of multipoint radio systems is to
provide fixed communication links between stations in a network supporting a different service (such as mobile
telephony). This application is frequently known as "infrastructure" or "backhaul".
Multipoint radio systems used in European countries have been specified up to now by a relatively large number of
specific European Norms produced by ETSI. There are separate equipment standards for ranges of radio frequencies
and access technologies. Similarly, there are separate antenna standards for ranges of radio frequencies. There is a
Harmonised European Norm which identifies the essential requirements (in accordance with article 3.2 of Directive
1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications
terminal equipment and the mutual recognition of their conformity (the R&TTE Directive) [17]) by cross referencing
the appropriate sections of the equipment and antenna standards. The present multipart standard replaces the current
multipoint radio equipment and antenna standards for all frequencies up to 33.4 GHz and the HEN which defines the
essential parameters for these multipoint radio systems. It thereby:

Presents the characteristics, parameters and requirements for multipoint radio systems in a much more concise
form.

Removes the extensive cross-referencing in the previous Harmonised EN.

Presents the characteristics, parameters and requirements for multipoint radio systems in a form which readily
permits comparison between the parameters applicable to different frequency bands and access technologies.

Facilitates the maintenance of the standard with a far greater degree of uniformity than possible with the
current disparate set of standards.

Facilitates the evolution of the standard in line with the strategy set by the European Commission.
The present multipart standard is divided as follows:
Part 1 includes for multipoint radio systems (equipment and antennas, whether integrated or not):

Descriptions and parameters of the general characteristics of multipoint radio systems

Recommended limits for parameters (Informative)

Specifications which may be complied with on a voluntary basis (Normative)

Informative text which assists in the understanding of the specification
Part 2 includes for multipoint radio equipment (whether or not integrated with an antenna):

Essential requirements as per the R&TTE directive
Part 3 includes for antennas used with multipoint radio systems (whether or not integrated with the equipment):

Essential requirements as per the R&TTE directive
For systems already covered by the previous HEN 301 753 [54], only equal or technically equivalent or less demanding
requirements have been used for this multipart EN. Therefore, from a strictly technical point of view, it is expected that
equipment already conforming to the previous versions of Harmonized EN 301 753 [54], would not need re-assessment
of essential requirements according to this multipart EN. The legal implications of the declaration of conformity and
equipment labelling are, however, outside the scope of this multipart EN.
As the scope of the present multipart standard is the superset of the scopes of the many earlier standards listed in the
Forward to the present document, and several of these standards themselves covered numerous different system
variants, any particular equipment need only comply with an unambiguous subset of the requirements in this multipart
standard. In the case of equipment (as opposed to antennas) a specific type of equipment shall be identified by an
Equipment Identification Code (EIC) which will specify the principal attributers of the equipment insofar as is
necessary to determine which aspects of this multi-part standard are applicable. The Equipment Identification Code is
specified in Annex 1.
The date of cessation of presumption of conformity to Directive 1999/5/EC of the European Parliament and of the
Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition

DEN/TM-04130-1 v0.0.2 (2003-03-25)
of their conformity (the R&TTE Directive) [17] with reference to EN 301 753 [54] is proposed to be two years after the
date of publication of this present multipart standard in the Official Journal of the European Community.
0.2
Applications overview
The main field of application of Multipoint (MP) systems using the Fixed Service (FS) is to provide access to both
public and private networks (PSTN, Internet, PDN, etc.). By means of MP systems the network service area may cover
scattered subscriber locations. The systems may be applied to build new access networks covering urban, suburban and
rural areas.
Subscribers are offered the full range of services by the particular public or private network. Subscribers have access to
these services by means of the various standardized user network interfaces (e.g. 2-wire loop, Ethernet and ISDN
ranging from basic rate to n × primary rate).
Multipoint systems provide standard network interfaces and connect subscribers to core networks. These systems allow
a service to be connected to a number of subscribers ranging from a few to several thousand, and over a wide range of
distances.
Multipoint systems are generally configured as Pre-Assigned Multiple Access Systems (PAMA), Demand Assigned
Multiple Access (DAMA) Radio Systems or a combination of the two.
Typical features of a typical MP Radio System are:
-
efficient use of the radio spectrum;
-
concentration;
-
transparency.
Radio is often the ideal way of obtaining communications at low cost and almost independent of distance, and difficult
topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid
implementation and minimizing maintenance requirements of the systems.
WP2:
Review and reconsider the above paragraph.
Concentration means that m subscribers can share n radio channels (m being larger than n), allowing a better use to be
made of the available frequency spectrum and at a lower equipment cost. The term "multi-access" derives from the fact
that every subscriber has access to every channel (instead of a fixed assignment as in most multiplex systems). When a
call is initiated one of the available channels is allocated to it. When the call is terminated, the channel is released for
another call. Concentration requires the use of distributed intelligent control which in turn allows many other operations
and maintenance functions to be added.
WP2:
Review and reconsider the above paragraph.
Transparency means that the core network and the subscriber equipment communicate with each other without being
aware of the radio link.
Typical services and applications delivered by such a system are:

Public switched voice

Public switched fax

Voice band data

ISDN

Digital video

Digital audio

Internet access

Videoconferencing


Remote LAN

Interconnection of corporate network domains
WP2:
DEN/TM-04130-1 v0.0.2 (2003-03-25)
Reconsider and rationalise the typical services list.
An alternative application for multipoint systems is to provide infrastructure or backhaul within the network offering a
different service. A typical example of this application is where a mobile radio network requires a number of base
stations, each supporting a relatively small amount of traffic, to be connected to a service node further up in the
hierarchy. A multipoint radio system may provide such connections without the expense of individual fixed digital
links (wired, radio or optical) being installed.
Multipoint systems may provide both access and infrastructure applications simultaneously.
0.3
Access and duplex methods overview
A variety of different multiplex methods is used in Point to Multipoint (P-MP) systems to multiplex together the signals
from the CS to a number of TSs and a variety of multiple access methods is used to provide multiple access from a
number of TSs to one CS.
Examples of multiple access methods are:
TDMA:
Time Division Multiple Access
MC-TDMA:
Multi Carrier Time Division Multiple Access
FDMA:
Frequency Division Multiple Access
DS-CDMA:
Direct Sequence Code Division Multiple Access
DS-CD/TDMA: Direct Sequence Code Division /Time Division Multiple Access
FH-CDMA:
Frequency Hopping Code Division Multiple Access
[TDMA/OFDMA
WP2:
TDMA / Orthogonal Frequency Division Multiple Access]
TR 101 274 written in 1998 may now require updating.
A basic description of someof the different access methods and a comparison among them is provided in TR 101 274
[77]
Generally, the multiplex method is analogous to the access method. For example, a system using FDMA as the
multiple access method from the TSs to CS typically uses Frequency Division Multiplexing (FDM) as the multiplexing
method from the CS to the TSs. However, this correspondence is not either universal or mandatory.
It should be noted that, in general, these access methods have different values of parameters applicable.
Two different methods are used to separate the two directions of signal in a bi-directional link:
TDD:
Time Division Duplex
FDD:
Frequency Division Duplex
0.4
Modulation and error correction overview
In order to transmit digital data across the radio frequency path, one or more parameters of the radio frequency signal is
modulated, typically frequency, phase or amplitude. For the commonly used modulation technique Quadrature
Amplitude Modulation (QAM), the two orthogonal phases of the signal are independently amplitude modulated, with
the number of discrete amplitude steps permitted for each phase determining the number of possible different states
each symbol may assume. In order to constrain the bandwidth of the modulated signal, either the modulating signals or
the modulated carriers are filtered.
Examples of modulation techniques which may be used in multipoint radio systems are:

QAM

OFDM
Orthogonal Frequency Division Multiplexing
DEN/TM-04130-1 v0.0.2 (2003-03-25)
The modulation order of the system is determined by the number of discrete states which may be assigned to each
symbol. The Modulation Order (EIC-MO) is one of the key components of the Equipment Identification Code of the
particular equipment, which determines which parts of the standard are applicable to that equipment. Annex 1 addresses
EIC and defines Modulation Order as log2(N), where N is the number of permitted values per symbol.
If the baud rate is B symbols/s, the maximum over-the-air bit rate, R, which may be transported by the system is:
R = B * log2(N) bit/s
All other factors being equal, modulation at higher orders is capable of carrying a higher bitrate in the equivalent radio
frequency channel when compared with modulation at lower orders, but it can tolerate less interference for the same bit
error rate.
The error performance of the system may be improved by the use of Forward Error Correction (FEC) or Automatic
ReQuest for retransmission (ARQ).
Forward error correction may use an inner code (such as convolutional coding), an outer code (such as Reed Solomon),
a concatenation of an inner and outer code, or an integrated inner and outer code (such as Turbo code). In general, FEC
incurs a constant delay to the data transported and a constant overhead to the available bit rate, although a system may
adapt the level of FEC to varying conditions.
ARQ detects the reception of data which are in error and requests retransmission of the faulty data. In general, the
delay to the data transmitted may vary, as may the overhead to the available bit rate, although bit error rates
approaching zero may be obtained for a wider range of conditions.
A multipoint system may use FEC, ARQ, both, or neither.

Definitions, symbols and abbreviations
3.1
Definitions
WP2:
A distinction should be made between a channel which is occupied by a carrier or set of carriers in a
multi-carrier or OFDM system and a unit of frequency allocation.
WP2:
May examine the consistency between these definitions in other ETSI, IEEE, CEPT and ITU references.
WP2:
Prefix all definitions related to FH-CDMA with “FH”. Similar prefixes may be required for other access
technologies. The text of the definitions may also require qualification.
For the purposes of the present document, the following terms and definitions apply:
channel spacing: separation between the centre frequencies of neighbouring RF channels. In cases where the RF
channel is not clearly defined, or (particularly for FH-CDMA systems) where the channel spacing is less than the
manufacturer's declared sub-channel bandwidth, the channel spacing is defined as the minimum continuous segment of
bandwidth made available to the system
chip: unit of modulation used in Direct Sequence Code Division Multiple Access (DS-CDMA) expressed as the
number of chips per second.
chip sequence: sequence of chips with defined length and chip polarities
direct Sequence Spread Spectrum: scheme where the data to be transmitted is combined with a fixed code sequence
(chip sequence)
NOTE:
This can be used to modulate a carrier
Direct Sequence Spread Spectrum (DSSS) modulation: A form of modulation whereby a combination of data to be
transmitted and a fixed code sequence (chip sequence) is used to directly modulate a carrier, e.g. by phase shift keying.
ETSI
21
DEN/TM-04130-1 v0.0.2 (2003-03-25)
Equipment Identification Code (EIC): A multi-field code which indicates the principal characteristics of a particular
equipment within the scope of the present standard which indicates which aspects of the present standard apply. (See
Annex 1 address the EIC concept.)
FH-CDMA dwell time: duration of a transmission on a particular sub-channel
Frequency Hopping (FH): spread spectrum technique whereby individual radio links are continually switched from
one sub-channel to another. Such links are not constrained to a single RF channel
FH-CDMA assigned band: aggregation of all RF channels assigned to a FH-CDMA system. The assigned band may
consist of several non-contiguous RF channels (see figure 1)
FH-CDMA sub-channel: integer sub-division of the RF channel(s) as determined by the equipment manufacturer (see
figure 1)
RF Channel
Sub-channel
Assigned Band
Figure 1: Relationship between "sub-channel", "RF channel" and "assigned band"
[DS-CDMA] Full Capacity Load (FCL): is defined by the maximum number of 64 kbit/s signals or the equivalent
which can be transmitted and received by a single CS within a specified RF-bandwidth, fulfilling given performance
and availability objectives in respect to fading conditions
gross bit rate: transmission bit rate over the air. In case of a transmitter working in burst mode the gross bit rate is the
instantaneous maximum transmission bit rate during the burst. The gross bit rate has a unique relationship to the symbol
rate through the implemented modulation format.
hopping period: time between the starts of successive transmissions on a different sub-channel. This is the sum of
dwell time and transition time
STF208 – To add Integral Antenna definition from STF190

[DS-CDMA] maximum system loading: maximum possible payload data rate on a single RF channel for the class of
operation declared by the manufacturer.
Multi-carrier system: system where more than one modulated sub-carrier is radiated from the same transmitter
NOTE 1: A system that uses several transmitters into a non-active antenna is not considered as a multi-carrier
system. Systems using FDM/OFDM modulation formats are also not considered multi-carrier unless
more that one separate FDM/OFDM signal set is transmitted from the same transmitter.
ETSI
22
DEN/TM-04130-1 v0.0.2 (2003-03-25)
NOTE 2: FDMA systems are intrinsically multicarrier, because any single sub-carrier may be easily discriminated
at RF level (unlike OFDM modulations) and activated according to the traffic requirements. However, for
the purpose of the present document, a FDMA system are also considered as a whole (fully loaded) single
signal set, unless more that one FDMA signal set is transmitted from the same transmitter.
nominal output power: maximum output power of the CRS, Terminal Station (TS) or Repeater Station (RS) referred
to point E' (figure 3) under Full Load Condition (FLC), as declared by the manufacturer
offset channel: radio channel at a frequency other than co-channel but closer than half the adjacent channel spacing.

figure 2 and the delay in the reverse direction between the same points
single DS-CDMA signal: single traffic channel and any associated signalling and synchronization overhead
single DS-CD/TDMA signal: single traffic channel and any associated signalling and synchronization overhead.
slow frequency hopping: FH technique where the hopping period is larger than the symbol period
system loading: total payload data rate on a single RF channel.

WP2:
DEN/TM-04130-1 v0.0.2 (2003-03-25)
Currently there are no antenna restrictions on Repeater Stations and if a Terminal Station can be a RS,
then omni antennas on TSs are now possible, hence major changes to sections 4.1 & 4.2 are required.
Multipoint fixed wireless systems are characterised by a systems architecture in which a number of stations are
interconnected by radio to deliver services from points of connection to a core network to connections to terminal
equipment. Figure 2 below shows a representative example of such a system.

Where:

TE is Terminal Equipment
TS is a Terminal Station which interfaces to one or more Terminal Equipment units
RS is a Repeater Station which provides a radio repeater outstation function and may also optionally interface to one or
more Terminal Equipment units
Any specific equipment within the scope of the present multipart document shall be a CS, a TS or a RS. The station
type (EIC-STN) for a particular equipment is one of the key components the Equipment Identification Code of the that
equipment which determines which parts of the standard apply to that equipment. Annex 1 addresses EIC.
The radio connections may be Point to Multipoint, whereby a Central Station or Repeater Station communicates with a
number of Repeater Stations or Terminal Stations using one of a variety of multiplexing and multiple access techniques.
In figure 2, Central Station (a) operates from a sectored or omnidirectional antenna in a Point to Multipoint
configuration, serving two Terminal Stations directly and two via a Repeater Station.
Alternatively, the Stations may be connected as an arbitrary mesh, using individual point to point links. In this case, the
mesh may be designed such that there are multiple paths to each Station. In figure 2, Central Stations (a) and (b) both
operate as part of a mesh network communicating with several Repeater Stations and Terminal Stations via directional
antennas.
It is permissible for a system to combine Point to Multipoint and mesh architectures.
The Central Station may, in addition to its function as an interface to the core network, perform a control function in the
system (such as the allocation of radio system capacity on a demand basis in a concentrated system). In this case, the
Central Station may be integrated or it may be divided into two units:
i)
the Central Controller Station (CCS);
ii)
the Central Radio Station (CRS) also called the radio unit which is the central baseband/radio
transceiver equipment. More than one CRS may be controlled by one CCS.
It is permissible for the CCS and CRS to be at separate locations as, for example, where the CCS is installed adjacent to
an exchange and the CRS is installed at a location which is optimal for radio coverage. Under these circumstances, the
CCS and CRS are connected by means of a digital transmission link.
ETSI
26
DEN/TM-04130-1 v0.0.2 (2003-03-25)
The Repeater Station may act simply to relay a signal received from a Central Station to Terminal Stations and further
Repeater Stations and, similarly, to relay the signal received from Terminal Stations and Repeater Stations back to the
Central Station. This mode of operation would most typically be found in a Point to Multipoint configuration, where
the Repeater Station fills in areas that would otherwise be in radio shadow from physical obstructions. Where a
Repeater Station is used in this way in a Point to Multipoint configuration, it will utilise a directional antenna facing the
Central Station or “upstream” Repeater Station and a sectored or omnidirectional antenna facing the Terminal Stations
or “downstream” Repeater Station(s).
Additionally, the Repeater Station may intercept and route traffic. A Repeater Station is typically used in this way in a
mesh network, where it acts as a node in the mesh network and transmits traffic on the optimum link to reach its
required destination or presents the traffic directly to the Terminal Equipment if appropriate. In a mesh application, the
Repeater Station will utilise a directional antenna for each link with another station.
A Terminal Station communicates with either a single Central Station or a single Repeater Station using a directional
antenna. It serves one or more terminals.
When a multipoint radio system is deployed in the access telephony network, it may be appropriate to connect the CS to
a local exchange, in which case the interface between the CS and the local exchange forms the SNI (Service Node
Interface), as described, for instance, in EG 202 306. Alternatively, where the CS incorporates local exchange
functionality, it may be appropriate to connect the CS directly to a trunk or international exchange, in which case the
interface between the CS and the exchange forms the NNI (Network Node Interface). In either case, the interface
between the RS or TS and the Terminal Equipment forms the UNI (User Network Interface), as described, for instance,
in EG 202 306. Analogous options apply when the radio system provides access functionality for IP services.
When broadcast or private networks are concerned, different interfaces are also possible. For example the CS may be
directly connected to the Core Network by means of a NNI interface and the switching functionality may be
implemented in the CS (e.g. the CS may incorporate an ATM switch interfacing into an ATM network) and, for private
networks, the interfaces to Terminal Equipment may be custom interfaces.
In the case where the multipoint radio system provides backhaul facilities for a different service, the function of the
multipoint system will usually be to provide a “bit pipe” between remote nodes (equivalent to Terminal Equipment on
the diagram) and core network nodes.
It should also be noted that Central Stations may not be co-located with core network nodes and the connection between
the two may be effected by radio links, optical fibre links, or other means.
Subscriber to subscriber connections may also be provided in some networks, not routed via an external core network.
In this case, connections may exist between Central Stations which are effected by radio links, optical fibre links, or
other means.
4.2
Antenna types
Antennas may be integral or non-integral.
Whether integral or non integral, antennas shall conform with the requirements of this standard and EN XXX XXX part

ETS 300 833 [76]
Permitted antenna types are as follows:

RF reference architecture
The RF-system block diagram, illustrated in figure 3, shows the point to point connection of a MP transceiver between
the CRS and one TS and vice versa.
When an RS demodulates and remodulates data, this diagram is also applicable to a point to point connection between
the CRS and RS, one RS to another RS, and an RS to a TS.
The ”Paylaod Processing” block contains the mapping functionalities required for transforming between the baseband
interface data format and the raw data stream sent to the modulator and received from the demodulator. It includes, but
is not limited to transforming between packet data protocols and the raw data stream.

Frequency bands and channel plans
5.1
Frequency bands
Frequency bands which are applicable to multipoint wireless access systems in the frequency ranges covered by the
scope of this standard are shown in table 2 below. Where a "shorthand" name for the band is commonly used, it is
shown in the first column of the table. Assignment of these frequencies on a national or geographic basis is subject to
national administration.
This standard may also be applied to other bands or parts of bands within the frequency ranges covered by the scope of
this standard as permitted by national administrations. Such application should be in accordance with appropriate
CEPT/ECC recommendations.
The frequency range (EIC-FR) for a particular equipment is one of the key components of the Equipment Identification
Code of the particular equipment which determines which parts of the standard apply to that equipment. (Annex 1
defines EIC.)
Attention should be given to assigning spectrum so as to allow different systems to operate in adjacent assigned
frequencies without unacceptable mutual interference. This is the responsibility of the regulatory authorities and these
are advised to note any guidelines produced by CEPT, particularly those with reference to spectrum where different
duplex methods are to be used.

WP2:
Would like 24.5 GHz to replace 24.25 GHz throughout the document.
AC:
It has been noted at SC that there is an ITU specification which may be applied. This should be checked
and either the ITU spec added and cross referenced or 24.25 changed to 24.5 thoughout parts 1 and 2.
5.2
Channel plans and block assignment
Channel plans which are applicable to multipoint wireless access systems in the frequency ranges covered by the scope
of this standard are shown in table 3 below.
The channel spacing appropriate to the multipoint system envisaged depends on the necessary customer transport
capacity, the overall number of customers connected to one CS in a serving area and the access method used.
The Channel Spacing (EIC-CS) is one of the key components of the Equipment Identification Code of a particular
equipment, which determines which parts of the standard are applicable to that equipment. For FDD systems, the
spacing between corresponding unplink and downlink channels, and its sense, is the duplex spacing. When applied to
TDD equipment, all allocated spectrum may be utilised by the bi-directional TDD signals and references in the present
document to tx/rx (duplex) spacing should be disregarded. Duplex Spacing (EIC-DS) for a particular equipment is one
of the [optional] components of the Equipment Identification Code of the particular equipment which determines which
parts of the standard apply to that equipment. Annex 1 addresses EIC.
Channel plans shall be consistent with national allocations and constraints.
It should be noted that many administrations will, in future, consider it more appropriate to allocate spectrum to
operators of multipoint systems on a block basis rather than an individual channel basis. As this practice evolves, it is
likely that operators will have the freedom to select channel arrangements within their allocation, provided that defined
block edge characteristics and maximum power/EIRP conditions are met.

Note 1:
In DS-CDMA systems the required channel spacing is determined by the chip rate. For the purposes of
the present document, the following example channel spacings have been defined: 5,0 MHz, 10,0 MHz
and 15,0 MHz. Corresponding parameters for spacings of 3,5 MHz, 7,0 MHz and 14,0 MHz in the
frequency range 1 - 3 GHz may be used. Further channel spacings are available by scaling proportionally
all channel-related parameters in the present document.
WP2:
The above note may be modified by the resolution of Issue 58.
Note 2:
Administrations may allow FDMA equipment to operate at alternative lower bandwidths than indicated in
table 3 achieved by subdivision of the channel spacing for 1,75 / 2 MHz channel operation.
Note 3:
In DS-CD/TDMA systems the required channel spacing is determined by the chip rate as well as the data
rate. The following example channel spacings have currently been identified:

3,5GHz, 3,7GHz and 10,5 GHz: 24 MHz

26GHz and 28 GHz:
3,5; 7; 14; 28; 56; and 112 MHz
Future developments may require different channel spacings. Further channel spacings are available by
scaling proportionally all channel-related parameters in the present document.
Note 4:
For FDMA systems, allocated RF-channels may be occupied by systems using smaller RF-channel
spacing as long as the spectrum mask for the allocated RF-channel is not exceeded.
Note 5:
For MC-TDMA systems, allocated RF channels may be occupied by systems using any number of subcarriers or size of sub-carrier bandwidth within a specific channel, as long as the spectrum mask for the
allocated RF channel is not exceeded, for any configuration of sub-carriers
Note 6:
These channel spacings, although not recommended by the referenced recommendations for these bands,
have previously been permitted by relevant multipoint standards and are therefore retained.

AC:
EN 301 055 and EN 301 179 (DS-CDMA and FH-CDMA at 1 - 3 GHz make reference to F.1098-1 as
applicable to the 1,5 GHz, 2,2 GHz and 2,6 GHz bands. In fact, F.1098-1 only applies to 1,9 GHz to 2,3
GHz, so the applicability of F.1098-1 should be checked before insertion in the above table.
AC:
The previous standards for 1-3 GHz bands included a multiplicity of different sets of permitted channel
spacings depending on band and access method. It was agreed at SC#3 that channel spacing should be
made a free variable. The new table therefore reflects this decision and permits all channel spacings
permitted by the relevant recommendations and also any additional spacings permitted by previous
standards. It should, however, be noted that for DS-CDMA and FH-CDMA, the co-channel and adjacent
channel interference parameters are currently specified for specific channels only. The correctness of this
(particularly for FH-CDMA) should be reviewed and, if necessary, a formula derived.
AC:
Although the majority of previous standards for the 1-3 GHz bands refer to F.701-2 for the 2.4 GHz
bands, EN 301 055 (DS-CDMA) refers to F.701-1. It is assumed in the above table that the reference to
F.701-1 is either a typographical error or a carry over from previous history and has therefore been
replaced by F.701-2.
AC:
Consideration should be given as to whether a common wording for notes 2 and 4 may be derived.
AC:
The move away from prescriptive channel spacing towards examples may mean that notes 1 and 3 can be
combined with a set of example channel spacings later in the document set where channel related
parameters are described.

This section inseted at the request of SC#6. Although currently blank it is reserved for transmit

Input level range
STF 208: Section on Input level Range maybe to be redrafted into an informative annex in part 1 .Final decision to
be postponed for further consideration
CC:
But the original standards do not always separate input level range from ATPC operating range. In fact
they nearly always specify dynamic range.
CC:
Definitions of these two different concepts are required.
CC:
The following text for 4.6.1 is the result of first stage of consolidation of the various standards by
suppressing repeated text. Where subtle but non-trivial variations of the wording occurs both/all variants
have been retained with their attribution. A summary of how the text could be merged into a single table
based presentation appears in a WD entitled “Synopsis of Receiver Input Level variations” as follows
The Input Level Range of the receiver is the range of power levels measured at Point C in the RF Block Diagram (see
figure 3) over which the bit error ratio (BER) will exceed 10 -3.
Table 4 defines, for the appropriate frequency range, nominal access method and station type, the input level above the
minimum receiver threshold for BER 10-3 (defined in the section " Minimum RSL" in part 2 of this standard) shall
remain 10-3 or less. The range shall be declared by the manufacturer [along with the modulation order at which this
range is achieved].
Note:
Input level Range differs from Dynamic Range, which incorporates also any further ability of equipment
to address the “near-far station” issue through the use of ATPC.
CC:
However, some standards also define dynamic (level) range in the receiver performance clauses. In some
cases this seems merely a misuse of terminology, in others it appears that a different concept is being
expressed.

Notes
1:
For the appropriate receiver type and a single DS-CDMA signal, the dynamic range above the receiver
threshold level defined in the section " Minimum RSL" in part 2 of this standard for the declared system
loading, for which the BER shall be 10-3 or less.
2:
The dynamic range for CS, and RS receivers facing terminal stations, is lower because ATPC is
mandatory for the corresponding transmitters.
3:
The input level range shall be large enough to enable the system to maintain its performance under the
entire range of pass loss values the system is defined to cope with. If the ATPC option is incorporated
within the system, the receiver input level range might be smaller than the path loss range.
4:
The dynamic level range shall be large enough to enable the system to maintain its performance under the
entire range of path loss values the system is defined to cope with.
5:
For systems with ATPC, the overall dynamic level range shall be large enough to enable the system to
maintain its performance under the entire range of path loss values the system is defined to cope with, the
dynamic level range shall exceed 50 dB..
6:
The input level range shall be large enough to enable the system to maintain its performance under the
entire range of pass loss values the system is defined to cope with.
7:
If the ATPC option is incorporated within the system, the receiver input level range might be smaller than
the path loss range.
ETSI

DEN/TM-04130-1 v0.0.2 (2003-03-25)

For repeater stations (facing terminal stations) and central stations the overall dynamic level range shall

Editor’s notes on the table
Ed1
Text says Dynamic Range but the context implies Input level Range
Ed2
Text says Receiver input threshold in one place and Dynamic Range elsewhere, but the context implies
Input Level Range is meant throughout.
7.2
Two tone interference
For multipoint equipment operating at frequencies below 1 GHz, a receiver operating at the RSL specified in the
relevant part for a 10-6 BER threshold, the introduction of two signals at frequencies offset from the channel centre
frequency by 450 % of channel bandwidth and 900 % of channel bandwidth respectively and at a level 30 dB above
the RSL should not cause a degradation of more than 1 dB in the receiver BER threshold.
For multipoint equipment operating at frequencies above 1 GHz, there is no requirement for immunity to two tone
interference.
7.3
Impulsive interference
WP2:
STF 208 to delete annex on impulsive interference
AC:
Deletion of informative annex not understood. The annex has therefore been left in for now.
For multipoint equipment operating in the frequency range 0,3 GHz to 1,0 GHz, the receiver BER shall be measured in
the presence of wide band impulsive noise at a quasi-peak level of -102 dBm, measured in a 120 kHz bandwidth. The
impulses shall be periodic with a repetition rate between 10 Hz and 1 000 Hz. The noise spectrum shall cover all the
channel(s) on which the receiver is operating. (Informative Annex C sets out the rationale for the level of impulsive
interference to be applied.) The manufacturer shall declare the degradation of receiver sensitivity corresponding to a
BER = 10-3 and 10-6 caused by the impulsive noise conditions defined above.
For multipoint equipment operating in frequency ranges above 1 GHz there is no requirement for immunity to
impulsive interference.
7.4
Distortion sensitivity
Multipoint equipment operating in frequencies below 1 GHz, should be capable of operating in non line of sight
environment. The manufacturer shall specify the equipment capacity and sensitivity under multipath conditions with
delay spread ranging from 0 to 20 s
For equipment operating in frequency bands above 1 GHz there are no requirements regarding distortion sensitivity due
to multipath fading.

Equipment types
AC:
The set of equipment types remains under study to define a set of types which has greater uniformity but
is flexible for future expansion. For the present, the system types from the current standards have been
retained.
The present standard includes a consistent set of recommendations and requirements for each of a number of identified
equipment types for each of the permitted combinations of frequency range and access method. The equipment shall
therefore be declared by the manufacturer as one of the types shown in table 5 below and shall conform to requirements
specified for that equipment type.

Note 1:
The types QPSK, GMSK and DQPSK are intended to be representative of these modulation techniques.
However, it is also permitted to apply an equivalent modulation scheme, if the system parameters are met
Note 2:
Where a reference made to the number of states of a modulation scheme, it is also permitted to apply an
equivalent modulation scheme, if the system parameters are met.
Note 3:
Class-A and Class-B represent orthogonal and pseudo random coding operation respectively.
Note 4:
For TDMA systems in the frequency range 1 - 3 GHz, system parameters are specified independently for
each permitted channel width and bit rate and these are therefore treated as separate sub-types.
Note 5:
In the earlier standard EN301 021, for TDMA systems in the frequency range 3 - 11 GHz, eight system
types were defined: A, B C, D, E, F, G and HC. These systems represent different spectral efficiency in
term of gross-bit-rate/Hz; the gross bit rate has a unique relation to the symbol rate through the
implemented modulation format. Table x below indicates the relationship between the earlier system
types and the present EIC:
ETSI
35
Note 6:
DEN/TM-04130-1 v0.0.2 (2003-03-25)
For TDMA systems in the frequency range 24.25 - 29.5 GHz, four system types were defined
in EN….: A, B, C, and HC. These systems represent different spectral efficiency in term of
gross-bit-rate/Hz; the gross bit rate has a unique relation to the symbol rate through the
implemented modulation format and these types are superseded by EIC-MO as follows:
System Type A is replaced by EIC-MO 2, System Type B by EIC-MO 4 and System Type C
by EIC-MO 6.
SubType HC has higher requirements for receiver sensitivity and tolerance to interference;
Note 7:
For MC-TDMA systems in the frequency range 24.25 - 29.5 GHz and TDMA and MC-TDMA systems in
the frequency range 31,0 - 33,4 GHz, three system types were defined in EN…..: A, B and C. These
systems represent different spectral efficiency in term of gross-bit-rate/Hz; the gross bit rate has a unique
relation to the symbol rate through the implemented modulation format and these types are superseded by
EIC-MO as follows: System Type A is replaced by EIC-MO 2, System Type B by EIC-MO 4 and System
Type C by EIC-MO 6.
For systems declared as of type FH-CDMA, the hopping period shall not exceed 400 ms.
CC:
Is this really the best place for the above 400ms requirement?
AC:
It's the only parameter which is truly dependent on access technology, rather than a technology neutral
equipment type and is therefore difficult to place. It has been left here for now.

System capacity
AC:
This section has been derived from the analysis output on this subject submitted to SC#3 and the minor
correction with which it was accepted at SC#3. It is recognised as being less than optimal in the long
term but the best compromise for continuity with existing standards at present.
WP2:
Gross Bit Rate, Payload Bit Rate, System Loading and Maximum System Loading will require updating
that will impact on the definitions and section 6
8.2.1
General
The system capacity is the traffic capacity of the system per radio channel of a given size.
For historical reasons, this capacity has been expressed differently for different nominal access methods and in different
frequency ranges. In the interests of maintaining continuity with the previous standards, the current version of the
present document retains this diversity of definition. It may be expected that future versions of the present document
will express the system capacity in a more uniform manner.

Capacity of TDMA and MC-TDMA systems
For TDMA systems operating below 1 GHz, the system capacity shall be declared by the manufacturer.
For TDMA and MC-TDMA systems operating at 1 GHz or above, the gross bit rate per Hz of channel width expressed
as bits per second per Hz (bps/Hz) must equal or exceed:
 For all cases not listed in Table XX below: (0.57145 x Modulation Order) bit/s/Hz;
 For special cases listed in Table XX below: (Factor x Modulation Order) bit/s/Hz

NOTE 1: The modulation order is used to define consistent sets of parameters. The actual modulation technique or
order need not correspond with those shown above provided that all parameters for the declared
equipment comply with those specified as a consistent set in this standard.
NOTE 2: Allocated RF channels may be occupied by systems using smaller RF-channel spacing as long as the
spectrum mask for the allocated RF channel is not exceeded.
NOTE 3: Minimumpayload capacity is defined in units of 64 kbit/s for convenience. The system may offer any
payload capacity provided the above limits are met or exceeded and the traffic presented to the equipment
need not be segmented in units of 64 kbit/s.
NOTE 4: Administrations may allow equipment to operate at lower bandwidth and capacities than indicated in
table 7 achieved by subdivision of the channel spacing (table 3) of equipment approved for 1,75 / 2 MHz
channel operation.
8.2.4
Capacity of DS-CDMA systems
For DS-CDMA systems, the minimum system capacity is defined as the number of 64kbit/s channels which may be
supported for any given channel width. Capacities of equivalent total bit rate are permitted.
The system capacity shall meet or exceed the following requirements:
For sub-type (EIC-ST) = class-A (orthogonal) systems:
N ≥ ΔF x 40 / 7
For sub-type (EIC-ST) = class-B (pseudo random) systems:
N ≥ ΔF x 16 / 7
Where:
N is the number of 64 kbit/s channels
ΔF is the channel spacing in MHz
This equates to a minimum system loading of
0.366 bps/Hz for Class-A systems
and
0.146 bps/Hz for Class-B systems
AC:
Note that EN 301 460-5 for systems below 1 GHz has a number of anomalies in this respect. This is the
subject of issue 58.

Capacity of FH-CDMA systems
For FH-CDMA systems operating below 1 GHz, the system capacity shall be declared by the manufacturer.
For FH-CDMA systems operating at or above 1 GHz, the supplier shall declare the maximum number of simultaneous
duplex 64 kbit/s channels or the bit rates which the equipment is designed to carry for each channel spacing supported.
Such declared capacity shall not be less than either 8  64 kbit/s channels or 500 kbit/s for each 1 MHz of channel
spacing. Examples of the required capacity appear in table 8.

Power supply
AC:
Whilst it may be appropriate for the CS to operate from conditioned 230V AC or -48V DC obtained from
a power supply compliant with ETS 300 132 part 1 or 2 respectively, it would appear likely that in many
applications the TS will operate from raw mains and an appropriate specification for this application
should be identified by TM4.
AC:
I do not find the reference to 24V in EN 300 132 part 2 listed by EN 301 055, 300 636, 301 744, 301 124
and 301 021. Is this an error, or does it appear in a different version to that which I have downloaded
(Sept 1996)?
AC:
EN 300 132 part 2 identifies 60V as being applicable only for a transitional period. Including 60V should
therefore be questioned.
AC:
Although EN 301 460-1, 301 179 and 301 253 permit supply voltages other than those tabulated, I have,
in the following text, required the equipment to operate from one of the tabulated supply voltages. This
achieves better uniformity, but could be questioned as potentially making previously compliant
equipment non compliant.
WP2:
Needs to retain Power Supply section as it is used under extreme conditions as highlighted in the
conformance test document for e.g. Carrier Power, Spectrum Mask and Frequency Tolerance.
The equipment shall operate from one of the input voltages shown in table 9 for DC supplies and one of the input
voltages and frequencies shown in table 10 for AC supplies.
230V AC supplies for to the CS will be in accordance with the characteristics specified in ETS 300 132 [66] part 1 and
48V and 60V DC supplies will be in accordance with the characteristics specified in ETS 300 132 [66] part 2.
It should be noted that ETS 300 132 [66] part 2 specifies 60V DC as being available only for a transitional period.

Antenna interface to equipment
9.5.1
Antenna input connectors
The input connector on the antenna at points D and D' on the RF system block diagram (figure 3) should be
mechanically compatible with the radio equipment. This should be agreed between the antenna supplier and the
purchaser in line with the overall systems design requirements. For antennas which are integrated with the radio
equipment, proprietary connection designs may be utilized. [In both cases, a suitable test fixture should be agreed and
used for test purposes.]
When flanges are provided at the input port of the antenna they should be in accordance with IEC 60154-1 [78] and IEC
60154-2 [79]
Attention is drawn to a range of coaxial connectors referred to in IEC Publication 60339-1 [84], IEC
Publication 60339-2 [85], IEC Publication 60169-1 [81], and CENELEC EN 122 150 [2]. However, it should be noted
that these standards are not exhaustive. The impedance of the input ports should be nominally 50  coaxial.
9.5.2
VSWR at the input port(s)
The maximum Voltage Standing Wave Ratio (VSWR) should be agreed between the equipment supplier and purchaser
in line with the overall system design requirements. For guidance, antennas with a VSWR in the range 1,9 to 1,1 are
typical. If applicable, this parameter should be measured with the radome in place.
9.5.3
Inter-port isolation
If applicable, this parameter should be measured with the radome in place.
The isolation between the input ports of a dual polarized antenna should be agreed between the equipment supplier and
purchaser in line with the overall system design requirements. For guidance inter-port isolation better than 25 dB is
typical for linearly polarised antennas and better than 15 dB is typical for circularly polarized antennas.
ETSI
42
DEN/TM-04130-1 v0.0.2 (2003-03-25)
The isolation between the input ports of a multi-beam antenna should be agreed between the equipment supplier and the
purchaser, in line with the overall system design requirements. For guidance, in the case of multi-beam antennas, interport isolation is typically 15- 20 dB.

Environmental and mechanical conditions
10.1
Environmental conditions
The equipment (or integrated antenna with equipment) shall meet the environmental conditions set out in ETS 300 019
[60] which defines weather protected and non-weather protected locations, classes and test severity.
The manufacturer shall state which class the equipment is designed to withstand.
WP2:
10.1.1
STF208 to add explanatary sentence concerning RTTE vs ETSI.
Equipment within weather protected locations (indoor locations)
Equipment intended for operation in temperature controlled locations or partially temperature controlled locations shall
meet the requirements of ETS 300 019 [60] classes 3.1 and 3.2 respectively.
Optionally, the more stringent requirements of ETS 300 019 [60] class 3.3 (Non temperature controlled locations), 3.4
(Sites with heat trap) and 3.5 (Sheltered locations) may be applied.
10.1.2
Equipment for non weather protected locations (outdoor locations)
Equipment intended for operation in non weather-protected locations shall meet the requirements of ETS 300 019 [60],
class 4.1 or 4.1E.
Class 4.1 applies to many European countries and class 4.1E applies to all European countries.
For systems supplied within a specific radio cabinet, which gives full protection against precipitation, wind, etc. the
ETS 300 019 [60] classes 3.3, 3.4 and 3.5 may be applied also for equipment intended for operation in non-weather
protected locations.
10.1.3
Antennas
If applicable, the radome should be in place.
The non-integral antenna should be designed to operate within a temperature range of -45°C to +45°C with a
relative humidity up to 100% for environmental conditions specified in ETS 300 019-1-4 [64]
The temperature range could be divided in two parts where at least one of the following ranges should be covered:
1) -33°C to +40°C;
2) -45°C to +45°C.
The antenna (or integrated antenna with equipment) should be designed to meet wind survival ratings specified

conditions at the site of intended application. If applicable, the radome should be in place.
For installation purposes, the deviation of the antenna main beam axis should not be more than 0,3 times the smaller of
the two azimuthal and elevation HPBWs, as a general guide, under the conditions specified in table 15:

Antenna characteristics
11.1
Antenna minimum gain
11.1.1
General
The gain of the antenna is specified as the maximum gain of the antenna with reference to an isotropic radiator and is
expressed in dBi. For some antenna types the gain is specified as a function of one or more declared design parameters.
Antenna boresight (and associated gain) does not necessarily correspond to the 0 reference direction (and its associated
gain).
The gain parameters apply for linearly polarised and circularly polarised antennas. The applicability of each set of
parameters to linear or circular polarisation is indicated for each set of parameters.
The parameters for linear polarised antennas apply equally to both horizontal and vertical linearly polarised antennas.
The parameters for circularly polarised antennas apply equally to antennas using either RHCP or LHCP.
11.1.2
Directional antennas
Where several directional antenna classes are specified in a frequency band, these are designated D1, D2, etc
The minimum boresight gain of the directional antenna, expressed relative to an isotropic radiator, shall be as detailed
in Table 16 below:

The single beam sectored antenna boresight gain shall exceed the values defined in Figure 4 as a function of sector

Some standards tabulate the minimum boresight gain at 15 and 180 degrees. However, the figures look
identical and the values for 3-11 GHz seem inconsistent with the Figures. C Walker suggests the
anomaly may be an error.
Sectored multi-beam antennas
A sector multi-beam antenna comprises two or more beams at different azimuth angles, sharing a common aperture.
Such antennas are provided with ports for each of the beams; all the beams may be active in the same time while using
different frequencies. Each beam may be used as the central station covering a specific sector.
ETSI
45
DEN/TM-04130-1 v0.0.2 (2003-03-25)
Such antennas are typically used in order to have several narrow beams at a smaller form factor, for aesthetic,
mechanical (such as space or wind loading) or cost reasons. This section focuses on sectored multi-beam antennas in
which the aggregate of all beams covers up to 180 degrees in the frequency range 3 GHz - 11 GHz.
Sectored multi-beam antennas use only linear polarization. The parameters apply equally to both horizontal and vertical
linearly polarised antennas.
The CS antenna boresight gain, for each beam of a multiple beam sectored antenna, shall exceed the values defined in
figure 5 as a function of beamwidth , in the range 10 to 90 degrees.

More clarity is needed as to where α refers to half beamwidth of a beam and where it refers to the half

The minimum gain for omnidirectional antennas is specified in table 17 below.
Note that no omni-directional antennas have been identified for the frequency range 24 GHz to 30 GHz.
The minimum nominal gains for the frequency range 1 GHz to 11 GHz apply to both linearly and circularly polarised
antennas.

11.2
Antenna labelling
Antennas should be clearly identified with weatherproof permanent label(s) showing the manufacturer’s name, antenna
type, serial number(s) and, where appropriate, polarization direction(s) and the type approval number. Integrated
antennas may share a common label with the outdoor equipment.
11.3
Passive inter-modulation performance
For some P-MP access methods the minimum Passive Intermodulation (PIM) performance of the antenna may need to
be taken into account. In such cases the PIM performance should be agreed between the equipment supplier and the
purchaser in line with the overall system design requirements. For guidance, PIM product limits can often exceed 100 dBc.

Annex A (normative):
Equipment Identification Codes
Decision: Potentially subject to revision depending on study during analysis phase – Agreed at STF 208 SC#1
CC:
This annex shows the structure of the Equipment Identification scheme. ETSI Guide to preparing
harmonised standards requires that the equipment type codes be simple alpha-numeric codes but the
Steering Committee has directed that the STF does not identify the codes at this stage, only the coding
structure. In the interim the various fields which together make up the Equipment Identification Codes are
show in plain language rather than encoded.
Decision: (Agreed at SC#3) There is a need for the proposed scheme to be described in the consolidated standard.
The STF is invited to propose whether it should be within the body of the document (Introduction or
Scope) or whether it is in a normative annex.
Decision: (Agreed at SC#3). A clear distinction must be made between the identification needed for declarations of
compliance under the RTTE directive and the supplier declarations made by a supplier submitting
equipment for testing by a test house. The additional parameters needed for the latter would normally be
indicated in the Technical Construction File.
Decision: (Agreed at SC#3). The terminology System Identification Code should be replaced by Equipment
Identification Code as it is individual equipment for which declaration of conformity is made,
recognising, for example, that there may be several different station types within a system and these must
each have declarations.
Decision: (Agreed at SC#3). Annex A,B,C should be reduced to a minimum, and reduce the coding of the various
components of Equipment Identification Code (It is not clear whether coding should be excluded from the
consolidated standard or whether it is just not to be further considered at this stage, but no further work
will be undertaken until the drafting of the consolidated standard and the matter can be discussed in
context.)
Decision: (Agreed at SC#3). For RTTE conformity purposes, “Frequency band” should be combined with a
statement on the duplex method to be used (TDD/FDD). However, duplex spacing does not form part of
the information required to be declared for this purpose as no other parameters are dependent upon the
duplex spacing itself. However, test houses will want the supplier to declare the duplex spacing (or range
of duplex spacings) andf its sense, where applicable, for which the equipment is to be tested.
Decision: (Agreed at SC#3). A new term should be found for “Access Method code”. SC#3 reconfirmed that this is
to identify a set of parameters and does not mandate that a specific access method be used. (A system
using Frequency Division Multiple Access but which complies with all the parameters defined in a
TDMA standard is deemed to meet that standard.) The new term should capture both the access method
and the single/multiple carrier concept if possible.
CC:
“Nominal Access Method” is the proposed term to replace “Access Method Code”
Decision: (Agreed at SC#3). The use of Spectral Efficiency Class to follow P-P approach was accepted by the SC.
However, subsequent discussions with TM4/WP2 challenge this - but work will continue on the SCpreferred basis, until the issue is re-examined.
CC:
Now “Modulation Order” is proposed – which is similar to SEC, but has a consistent (log base 2)
arithmetic relationship with the number of modulation states.
Decision: (Agreed at SC#3). Many of the Equipment Identification Codes will not have single values – but may
have a range of values specified by the manufacturer. The text for inclusion in the consolidated standard
should reflect this.
Decision: (Agreed at SC#3). Further work on this subject should be directed towards drafting the exact wording for
inclusion in the standard now that the principles have been established.

This section is still subject to study and agreement of coding to be used with the SC. When this is done,
the section will be completed and the body of the document updated to use the new, uniform system
types.
Rationale
This Clause is included by way of rationale. It is felt useful in the first edition of the multipart standard as
it provides a bridge with the former situation. However, it should perhaps be removed in later revisions
once the proposed system is established.
The present multipart standard supersedes several multipoint equipment standards. Many of these earlier standards
identified alternative sets of parameter values which equipment must comply to be compliant with the standard. In some
of the earlier standards these were referred to as different system types usually distinguished by a single letter (or
occasionally two letters) – in other cases they are just distinguished by a principal distinguishing feature (such as the
order of modulations). Several of such earlier standards included Annexes which indicate “System Type Codes”, which
together with the standard’s own EN number, provided a means of identifying a particular variant system covered by
the standard. Such identification was intended to be used for licensing purposes, so that the licensor could stipulate
specific variants of the standard to be allowed. It was also intended for manufacturers to specify to test houses, and
others concerned with approvals, the variant of the system that is being offered for test. They could also be used for
procurement purposes.
Within the scope any specific former multipoint standards, these System Type Codes were intended to identify the
system in sufficient detail to allow the determination from the EN of the limiting values of relevant parameters and
attributes, such as the applicable frequency band (or CEPT frequency/channel plan), the minimum system capacity, the
transmit spectrum mask, BER as a function of RSL, and co-channel and adjacent channel interference characteristics.
However, this system was flawed for several reasons:
 It was not implemented for all standards and so was not a complete identification system;
 It did not codify all variants of the standard, as it had not been maintained rigorously when variants have been
introduced.
 The sequential allocation of decimal integers for the various references does not reflect the multi-dimensional
aspect of the variants and the original logical sequence has proved difficult to maintain.
 Some variants of the systems have been codified by extending the System Type Code in an ad hoc way with
little consistency across standards.
 One aspect of the variants that was codified in the one-dimensional reference was channel spacing, but in some
standards this can now take very large numbers of values, making the numbering unmanageable.
For these and other reasons, the earlier System Type Codes are no longer used to any extent. Furthermore, given the fact
that the many different multipoint standards will be replaced by the present multi-part standard, the System Type Code
would need to be extended so as to also indicate the access method and the frequency band, which currently are implied
by the current EN number.
The System Type Code is superseded by a multi-field reference, each field of which characterises one aspect of the
system. This new means of identifying system variants is called Equipment Identification Code – or EIC.
Each equipment variant covered by the present multipart standard will have an EIC. Most multipoint systems will
comprise at least two different equipment types (typically a Central Station and a Terminal Station) which will have
distinct, but similar EICs – typically differing only in terminal type.
A2
Identification of the parameters forconformance declaration
The multipoint conformance testing standard, EN301 126-2-1 [] lists the attributes that a manufacturer has to claim
when submitting multipoint equipment for conformance testing.
ETSI
49
DEN/TM-04130-1 v0.0.2 (2003-03-25)
A subset of this list of aspects needs to be selected by a supplier asserting conformance with the essential parameters of
Part 2 of the present standard. A number of attributes of the equipment for which compliance is claimed are necessary
to identify uniquely the particular variant of the many variants of multipoint equipment within the scope of this
standard. This set of attributes is encoded as an Equipment Identification Code(EIC). It comprises seven [six] fields
representing seven [six] different aspects of the equipment as described in Table A1.
Where the present standard offers different permitted values (or ranges of permitted values) of parameters for different
variants of equipment, the appropriate value or range can be uniquely inferred from the EIC, either by identifying the
appropriate table entries or by allowing calculation using an function of the EIC given by an explicit formula. Some
examples of the parameters which differ according to equipment variant and which are selected by the EIC are:
 The minimum system capacity
 The transmit spectrum mask
 The dynamic level range
 BER as a function of RSL
 Co-channel interference sensitivity
 Adjacent Channel interference sensitivity
EIC is a multi-field code specified in the form of a Table A1 which is to be completed in accordance with the
instructions in Table A2

STF had made suggestions on how these fields might be encoded but the SC directed that no further work
be done on the codification so instead a “plain language” statement for each filed is currently proposed
until such time as a codification scheme can be developed.

For historic reasons, alternative sets of parameters are
identified by the multiple access method originally associated
with them, although the actual multiple access methods need
not be the same as the nominal access method.
Possible codes are: FDMA, TDMA, DS-CDMA, FH-CDMA,
MC-TDMA, DS-CD/TDMA
The code(s) for sub-type depends on the context, and often
is unnecessary. See appropriate clauses of standard for
details where sub-type is quoted in defining permitted values
of one or more parameters.
Examples: HC and OFDM in the context of
EIC-FR = 3-11GHz, EIC-NAM = TDMA
The field is optional as it is not an essential parameter for
conformance statements nor does it discriminate permitted
parameters within the scope of the present standard.
However, suppliers may specify the duplex spacing and
sense for FDD equipment.
Example: -100MHz (where minus indicates CS transmits at
lower frequencies, plus indicates CS transmits at higher
frequencies)

Annex B (informative):
Impulsive interference below 1 GHz
The test level for man-made noise is derived from the specification for vehicle emissions included in European
Directive 95/54/EC [18]. This represents the noise source in rural areas with low vehicle traffic conditions and is also
consistent with a number of measurements made in the 0,3 GHz to 1 GHz band (i.e. COST 207). The specification level
is -112 dBm, quasi-peak, measured in a 120 kHz bandwidth, and exhibits a -20dB per decade frequency dependence.
Other sources of man-made noise are generally at a much lower level (see ITU-R Recommendation 372-6 [110]. In
order to account the worst case scenario whereby the noise arrives on bore-sight of the antenna connected to the
equipment, a term is added to account for antenna gain. Because antenna gain is not part of the equipment specification,
it is accounted for by using a general term rather than a variable attribute of different antennas. In the frequency range
of interest, antenna gain is limited by size (and cost) constraints to a maximum value of around 10 dB at 1 GHz,
including feed losses. This increases the noise specification level to -102 dBm at 1 GHz.
For a given physical antenna size, standard antenna theory shows that antenna gain is inversely proportional to the
square of the wavelength. It therefore exhibits a +20 dB per decade frequency dependence, and this is followed fairly
closely in practical designs within the 0,3 GHz to 1 GHz frequency range. As the frequency dependence of the antenna
gain and quasi-peak power are in opposite directions they cancel, removing frequency dependant terms from the present
document.
Annex C (informative):
Receiver selectivity
In order to facilitate interference calculations with other services both within and from outside the Fixed Service, the
receiver selectivity should be made available by the manufacturer. However the definition and the method of
measurement are under study within ETSI WG-TM4. Refer to work item DTR/TM-04121
Annex D (informative):
Traffic path characteristics
D.1
Synchronisation of traffic interfaces
Systems providing services based on the transport of constant bit rate digital data may be required to synchronise the
transmitted data to the digital bitstream received from the core network. Where such services are supported, appropriate
internal and/or external synchronisation should be provided.
In the extreme case where systems provide services from two or more core networks which are not synchronised with
each other, the system may be required to synchronise independently the transmitted data corresponding to the digital
service from each independent core network.
The principles for synchronisation should be according to ITU-T Recommendation G.810 [124]. Tolerances should be
according to ITU-T Recommendations G.812 [125] and G.823 [128] for systems providing PDH interfaces and/or
ITU-T Recommendations G.813 [126] and G.825 [129] for systems providing SDH interfaces.

Transmission error performance

System requirements for error performance
For the delivery of digital services at bit rates below the primary rate, the equipment covered by the present document
should be designed to meet the requirements for error performance specified in ITU-R Recommendation F.697-2 [96],
based on the definitions of Errored Seconds (ES), Severely Errored Seconds (SES) and Errored Second Ratio (ESR)
given in ITU-T Recommendation G.821 [127].

For the delivery of digital services at bit rates at or above the primary rate, the equipment covered by the present
document should be designed to meet the requirements for error performance specified in ITU-R Recommendation
F.1189-1 [105], and parameters from ITU-T Recommendation G.826 [130] as specified by F.1189-1.

Equipment Residual BER (RBER)
The following section has been transferred to this position in accordance with the resolution of issues 113
and 131. Note has been taken of the text produced by STF 190, but STF 208 see little commonality, since
the P-P definitions apply values appropriate to trunk transmission, not access, and refer to frequency
bands and co/cross polar deployment which are inappropriate. This section remains, however, very
unsatisfactory and, given the expiry of STF 208 budget, issues 113 and 131 have been referred back to
TM4/2 for further investigation.
The following specification for RBER should be a design objective.
The equipment BBER under simulated operating conditions should be measured with a signal level at reference point Z
of figure 3 which is 6 dB above the specified level for BER = 10 -6 in EN XXX XXX part 2, taking into account the
actual test load conditions.
For different payload bit rates the measurement time and the maximum number of errors allowed for digital services are
given in table 18.

For bit rates between 64 kbit/s to 2 048 kbit/s the values for the recording time
and the maximum number of errors shall be linearly derived from the value for
 2 048 kbit/s in applying the next higher integer value.
The note in the table above for rates between 64k and 2 048k (taken from EN 301 213-1 and 26_03_08r1)
is unclear. It could be read as interpolating between 0 and the 2 048 rates (i.e. the recording time for 1
024k would be int(7.5) = 8 hours). However, this would mean that the recording time would increase
with increasing bit rate which does not seem correct. It might be better to state that the recording time in
hours and the max errors are interpolated between the 64k and 2 048k and rounded up. Better still, a
more rigorous approach to RBER would be desirable if it is retained.
For systems transporting voice band signals the maximum number of errors shall not exceed 10 during a minimum
recording time of 24 minutes.
For MC-TDMA systems, the requirement shall be met by each sub-carrier. The effect of differential attenuation of the
sub-carriers, due to different rain intensity within the sector and/or ATPC, shall be taken into account. Therefore the
above requirement shall be met with the adjacent sub-carrier(s) RSL set to the higher differential power, with respect to
the sub-carrier under actual measurement, permitted by the system implementation, as declared by the supplier.
D.3
Availability
All equipment should be designed to meet the availability requirements specified by ITU-R Recommendation F.557-4
[94], based on the definition of Severely Errored Seconds (SES) given in ITU-T Recommendation G.821 [127].

Round trip delay
The round trip delay is defined with reference to figure 2 as the delay from the Terminal Interface to the Core Network
Interface and back to the Terminal Interface.
The round trip delay for a voice encoded 64 kbit/s traffic channel should not exceed 20 ms.
Longer round trip delays may result at other bit rates and when using speech coding at rates lower than 64 kbit/s. In
order to guarantee that the delay introduced by the multipoint system into the transmission network does not degrade
the quality of the telephone communication, compliance to ITU-T Recommendation G.131 [113] should be ensured.
Where echo cancellers are used, the characteristics should be stated by the manufacturer.
D.5
Voice coding methods
For systems providing voice services, it is recommended that at least one of the following coding methods should be
used:
-
64 kbit/s
ITU-T Recommendation G.711 [116];
-
32 kbit/s
ITU-T Recommendation G.726 [119];
-
16 kbit/s
ITU-T Recommendation G.728 [120];
-
8 kbit/s
ITU-T Recommendation G.729 [121];
-
5,3/6,3 kbit/s, dual rate ITU-T Recommendation G.723.1 [118].
Other voice coding methods may be employed if the quality is adequate for the service provided. It is recommended
that, in order to assess the adequacy of the quality for the service provided, it should be measured in Quantization
Distortion Units (QDU) or Mean Opinion Score (MOS) and compared with that of the coding methods listed above.
It should be noted that G.711 provides transparency to all voice band signalling and data modem signals and is provided
as a digital interface to many digital switches. It should be noted that for the majority of European applications, the A
law companding option in G.711 should be selected for compatibility with the switch.
It is recommended that the coding method or methods used should be stated by the manufacturer.
D.6
Transparency
The services offered over the Radio system should be, as far as possible, fully transparent. By this, it is meant that the
Core Network and the Terminal Equipment (at the interface points shown as the Core Network Interface and Terminal
Interface in figure 2) communicate with each other without being aware of the radio link.
Exceptions to this requirement for transparency are as follows:
Concentration of voice and data traffic may be employed to increase the efficiency of spectrum utilisation. It should
be noted that features of concentration may affect the network design, including the following:

the means by which circuit unavailability is signalled to the user and/or network for circuit switched
calls

the means by which flow control is signalled to the user and/or network for data transmission

the rules by which data are discarded if flow control is not supported
Aggregated interfaces at the network interface may be employed. In this instance, the type of transcoding of speech,
data, addressing, or signalling applicable to the change in interface type between the user interface and the network
interface may affect the network design.
Compression of traffic may be employed to increase the efficiency of spectrum utilisation. Examples of such
techniques are companding, speech codecs and digital speech interpolation. The standards or algorithms to which the
ETSI
54
DEN/TM-04130-1 v0.0.2 (2003-03-25)
compression and decompression functions conform may affect the netwrk design and it should be noted that some types
of traffic (e.g. voiceband data) may not be supported on circuits employing these techniques.
Data routing and/or filtering may be supported by the radio system. In this case, the filtering and routing algorithms
supported, together with any address translation will affect the network design, as will the method by which such
routing or filtering functions are configured.
Reduction of data rate or increased error rate may occur due to interference or propagation effects and any
signalling used from the radio system to the user or the network to indicate that the link is unavailable or available only
with restricted bitrate or increased error rate should be taken into account in the network design.
