Procedure for modifying or adding an assignment
• An administration wishing to modify the characteristics of an
assignment in the Plan or to add a new assignment must
preferably seek agreement directly from those administrations
whose services are liable to be affected.
• It then sends BR the characteristics of the modification or
addition electronically or using a T01 form of notice (Circular
Letter CR/120), indicating the names of the administrations
with which agreement has been reached.
• The Bureau determines those frequency assignments in
conformity with the Plan that may be affected and publishes
the characteristics of the modifications in Part A of a GE84
Special Section together with the names of those
administrations that have given their agreement and those from
which agreement must be obtained.
Procedure for modifying or adding an assignment

When an assignment in conformity with the Agreement is withdrawn, the
administration concerned so informs the Bureau immediately using TB5
forms of notice. The Bureau publishes this information in Part C of the
GE84 Special Section and updates the Plan.
Notification of frequency assignments
• An administration wishing to bring a broadcasting assignment
into operation in conformity with the Agreement must notify it
to the Bureau in conformity with the provisions of Article 11
of the Radio Regulations.
• When the assignment brought into use is in conformity with
the technical characteristics set forth for the assignment in the
Plan, it is then entered into the Master International Frequency
Register(generally known as the MIFR).
Example table of coordination distances
• Different tables are used for various types of propagation path.
These are incorporated in SMS4DC and used for BC2BC
coordination menu function.
• If the station coordination distance (given in the appropriate
table for the station e.r.p) is greater than the distance from the
station to the border, the station must be coordinated
Coordination of Minimum FS and protection ratio
• Minimum field strength: The planning was based on the
following median values of the minimum usable field strength
(measured 10 m above ground level):
Areas
Services
Monophonic [dBμV/m]
Stereophonic dBμV/m]
Rural
48
54
Urban
60
66
Large cities

74
An Administration Should Normally Accept the
Proposed Modification Provided that:
• The resulting usable field strength is not greater than 54 dB(μV/m); or
• The resulting usable field strength is greater than 54 dB(μV/m), but is
increased by 0.5 dB or less compared with the reference usable field
strength. An increase of more than 0.5 dB is open to negotiations, in
which more detailed calculation methods may be used.
Some definitions from the plan
• Coverage area: The area within which the
field strength of the wanted transmitter is
equal to or greater than the usable field
strength. In this area the protection against
interference is provided for 99% of time.
• Service area: The part of the coverage area
in which the administration has the right to
demand that the agreed protection
conditions be provided.

Standard and variants (1/2)
Within the standard for digital television there are many
variants. Within these variants in the DVB-t family of
standards different options in relation to various technical
parameters, such as the number of carriers, modulation
schemes, coding rate, guard interval, etc. are available.
 These variants has an impact on the type of broadcast service
delivered (i.e. conventional multi-channel television,
handheld/portable television or high definition television), as
the different options generate different planning parameters
and this in turn can have a significant impact on network
capacity, design and cost of implementation.

No of Programs (Quality Versus Quantity)
 There
is a link between the standard and variant selected for
digital broadcasting, the quality of the programme services
and the quantity of services available (i.e. HDTV SDTV).
 Different
types of multiplexing and system variants provide
differing quality and services. In order to provide an
acceptable video and audio quality in conventional displays
there are certain minimum parameters.
Approach to planning(1)
The ITU have indicated that planning for DTT can be
based on either assignment or allotment planning.
ALLOTMENT
ASSIGNMENT
Is a set of administrative, technical and
geographical
parameters
uniquely
describing the use of a radio frequency (or
a radio frequency channel) in one or more
identified countries or geographical areas
by one or more radio stations under
specified conditions and being recorded in
corresponding file or record
Is a set of administrative, technical
and geographical parameters uniquely
describing one single radio-station (or
multiple radio-stations, in case of
typical stations) being recorded in
corresponding file or record
Approach to planning (2)
 Reference
field strength: The agreed value of the field
strength that can serve as a reference or basis for frequency
planning.
 Test points: A test point is a geographically defined location at
which specified calculations are carried out.
Approach to planning (3)




Coordination trigger field strength: Field-strength level which, when
exceeded, determines that coordination is required (also referred to as
trigger field strength).
Fixed reception: Fixed reception is defined as reception where a
directional receiving antenna mounted at roof level is used.
Portable reception :Portable reception is defined as:
 class A (outdoor), which means reception where a portable receiver
with an attached or built-in antenna is used outdoors at no less than 1.5
m above ground level;
 class B (ground floor, indoor), which means reception where a portable
receiver with an attached or built-in antenna is used indoors at no less
than 1.5 m above floor level in rooms
Mobile reception: Mobile reception is defined as reception by a receiver in
motion with an antenna situated at no less than 1.5 m above ground level.
This could for example be a car receiver or handheld equipment.

Multi-frequency network (MFN): A network of transmitting stations
using several RF channels.
Single-frequency network (SFN):A network of synchronized transmitting
stations radiating identical signals in the same RF channel.
Reference planning configuration (RPC): A representative combination
of criteria and parameters to be used for frequency planning purposes.
Reference network (RN): A generic network structure representing a real

Network parameters (Reception modes and coverage quality)



Traditionally television planning was based on the use of a rooftop aerial,
however an indoor portable reception &outdoor portable and mobile
reception has also evolved to a limited extent in recent years.
With the traditional analogue system, as the signal level reduces it is still
possible to receive a viewable picture (bad quality). As a consequence of
this gradual degrading in picture quality it was possible to provide
reasonable level of coverage even where the planned median signal level
may not be full met. However with a digital reception, there is a very
rapid transition from perfect picture to no picture. Consequence portable
reception, particularly indoor will be more problematic to achieve unless
it is considered at the planning stage.
If there is a demand for portable and mobile reception, that may result in
either an increase in the transmission power required or in the number of
stations necessary to serve a given area. This in turn can impact on the
number of multiplexers that can be accommodated in a given area.
Network parameters (Network structure and coverage areas))



The type of transmission system and location of the transmitter is a more
complex consideration with digital broadcasting than with analogue
broadcasting.
Networks can be planned using either, one frequency channel at the various
stations in the network, or using a number of different frequencies throughout
the network. The former are referred to as a single frequency networks (SFN)
while the latter are called a multi-frequency network (MFN).
As single frequency network use the same frequency channel at each of the
transmission stations within the network, there is a considerable reduction in the
amount of spectrum required. While this would allow more multiplexes to be
considered, its disadvantage is that it requires a more complex support
infrastructure (i.e. method of feeding the signal to each of the broadcast stations
particularly fill-in stations). In addition the content must be the same
throughout the entire service area (not possible to have regional opt outs in a
national network.
Multi frequency networks requires more spectrum to provide services in a given
area. However this type of network would facilitate the provision of different
programmes to different parts of the service area (Regional programming).

presence of natural and man-made noise, but in the absence of
interference from other transmitters.
NOTE 1 – The term “minimum usable field strength” corresponds to the
term “minimum field strength to be protected” which appears in many ITU
texts and it also corresponds to the term “minimum median field strength”,
which appears as Emed as well.
RPC/RN (1/3)

A generic network structures with geometrical symmetry and homogeneity with
regard to transmitter characteristics, called Reference Networks (RNs) is used as
reference in the earlier planning stages.

The use of RNs for the compatibility analysis is bound to the use of RPCs since
the characteristics of the transmitters at each RN differentiate according to the
RPC. There are four kinds of RNs, each corresponding to a different wanted
reception type and service area characteristics.

The reference network (RN) classes and the reference planning configurations
(RPC) are put together in a matrix, which results in 12 instances for DVB-T and
two instances for T-DAB

Coverage Area calculation using
SMS4DC
“Calculation of noise-limited coverage area (coverage area)”
Coverage area
 The
coverage area of a broadcasting station, or a group of
broadcasting stations, in the case of a single-frequency
network, is the area within which the wanted field strength is
equal to or exceeds the usable field strength defined for
specified reception conditions and for an envisaged
percentage of covered receiving locations.
 SMS4DC calculates noise-limited and interference-limited
coverage areas for a wanted broadcasting assignment.
 The noise-limited coverage area, as well as the interferencelimited coverage area will be displayed on the DEM map
Step One: Select a Broadcasting agreement to draw the
coverage area (for example GE06)
Step Two: Select the wanted assignment to estimate the
coverage area
