FOREWORD
1.1
This Standard Radio System Plan (‘SRSP’) is prepared by the
Malaysian
Communications
and
Multimedia
Commission
(the
‘Commission’) to provide information on the minimum technical and
regulatory requirements for the efficient use of allocated frequency
bands as described in the Spectrum Plan, the extract which can be
found in Appendix A.
1.2
This SRSP provides information on characteristics of radio systems,
frequency channelling, and coordination initiatives in maximising
the utilisation of the allocated frequency bands and in minimising
interference.
1.3
This SRSP is intended to regulate the use of the allocated frequency
bands and does not attempt to establish any detailed equipment
standards.

INTENT
2.1
This SRSP states the requirements for the utilisation of the
frequency bands 13.75 GHz to 14.40 GHz and 15.70 GHz to 16.60
GHz (the ‘allocated frequency bands’) for Fixed Wireless Access
(‘FWA’) systems in Malaysia.
2.2
FWA systems are two-way point-to-point or point-to-multipoint
radio systems consisting of FWA central/ hub stations and their
associated customer premise equipment(s) or FWA access devices.
2.3
FWA services are intended to provide broadband connectivity to
subscribers and may include applications such as voice, video,
images, interactive multimedia and high-speed data.
3.0
GENERAL
3.1
Equipment(s) to be used for the FWA systems in the allocated
frequency bands shall:
3.1.1 Conform with the Communications and Multimedia Act 1998
and its subsidiary legislation made under the Act;
3.1.2 Conform with the requirements, specifications and standards
(any Malaysian standard, International standards, technical
standards,
mandatory
standards
and
technical
codes
registered by the Commission) that apply to the FWA
systems decided by the Commission; and
3.1.3 Be certified by the Commission or its registered certifying
agency and bear a proper SKMM certification label in
accordance
with
the
Communications
and
Multimedia
(Technical Standards) Regulation 2000.
3.2
The installation of the equipment(s) shall comply with the relevant
safety rules as provided in the applicable standards stated in
paragraph 3.1.2 above.

3.3
This SRSP is not exhaustive and may be reviewed by the
Commission from time to time to reflect the new development in
the country’s communications and multimedia industry.

CHANNELLING PLAN
4.1
FWA radio systems operating in the allocated frequency bands shall
use 13.75 GHz band to 14.40 GHz band for FWA central/ hub
stations receive (uplink) and FWA access devices transmit, and
15.70 GHz band to 16.60 GHz band for FWA central/ hub stations
transmit (downlink) and FWA access device receive. The issuance of
assignment shall be made based on the channelling plan in
Appendix B.
4.2
The channels in the spectrum bands from 13.75 GHz to 14.40 GHz
and 15.70 GHz to 16.60 GHz are as shown below:
Centre frequencies of uplink channels can be calculated by the following formula:
fn= 13.75 + 17 + 14 + (n x 28) GHz
where is:
•
13.75 – lower uplink channels frequency band limit
•
17 – lower frequency band protection gap
•
14 – half of data channel bandwidth
•
n = 0…21 – number of channel
Centre frequencies of downlink channels can be calculated by the following
formula:
fn= 15.807 + 17 + 14 + (n x 28) GHz
where is:
•
15.807 – lower downlink channels frequency band limit
•
17 – lower frequency band protection gap
•
14 – half of data channel bandwidth
•
n = 0…21 – number of channel
5
MCMC SRSP-547 FWA
4.3
Each operator will be allowed to use frequency channels within any
28 MHz wide blocks as illustrated in Appendix B.
There are 22
channels assigned for each horizontal and vertical polarisation for
13.75 GHz to 14.40 GHz.
Similarly, there are 22 channels also
assigned for each horizontal and vertical polarisation for 15.75 GHz
to 16.60 GHz.
The following formula describes the start frequencies for channels 1
through to 22 for both uplink and downlink.

REQUIREMENTS FOR USAGE OF SPECTRUM
5.1
This SRSP covers the minimum key characteristics considered
necessary to make the best use of the available frequencies.
5.2
These FWA spectrum bands are not limited in their use for direct
radio connection between a radio fixed station and customer
premise equipment (CPE) in a point-to-point or point-to-multipoint
configuration. It may also be used for backhaul links from a radio
base station to a repeater station.
5.3
Only systems using digital technologies that promote spectral
efficiency will be issued with an assignment. Capacities enhancing
digital techniques are being developed rapidly and such techniques
that promote efficient use of spectrum, without reducing quality of
service are encouraged.
5.4
A radio system conforming to the requirements of this SRSP may
require modifications if harmful interference is caused to other radio
stations of the same service within the same band, and/or other
radio stations or systems of other services within the same band,
and/or other radio stations or systems of other services in the
adjacent bands.
5.5
Maximum equivalent isotropically radiated power (e.i.r.p.):
a)
FWA central/ hub stations receive (uplink) and FWA
access devices transmit in the 13.75 GHz band to
14.40 GHz band shall not exceed +45 dBW; and
b)
FWA central/ hub stations transmit (downlink) and
FWA access device receive in the 15.70 GHz band to
16.60 GHz band shall not exceed +55 dBW.
8
MCMC SRSP-547 FWA
5.6
The allocation of spectrum and shared services within these bands
are found in the Malaysian Spectrum Plan and an extract of it is
shown in Appendix A.
6.0
PRINCIPLES OF ASSIGNMENT
6.1
Authorisation to use the allocated frequency bands for FWA is by
way of Apparatus Assignment (AA) and shall be on a first come first
served basis.
6.2
Persons who are eligible to apply for AA are Network Facilities
Provider
Individual
(NFP
(I))
licence
holders,
who
provide
radiocommunication transmitters and links.
6.3
Applicants are required to submit AA application for the apparatus
on the prescribed AA forms.
6.4
Issuance of AA is subject to successful coordination among assigned
stations and with neighbouring administrations where it applies.
6.5
Applicant is encouraged to coordinate among existing stations prior
to submission of AA application.
7.0 IMPLEMENTATION
7.1 This SRSP shall be effective on the date of its issuance.
8.0
COORDINATION REQUIREMENT
8.1 Use of the frequency band from 13.75 GHz to 14.40 GHz shall require
coordination with the Fixed Satellite Services (FSS) hub earth
stations. A coordination zone of 3.5 km shall be established for the
FSS hub earth stations as shown in Appendix C. Use of frequency
bands that are assigned to FSS by FWA shall be on non-interference
basis to FSS.
9
MCMC SRSP-547 FWA
8.2 Use of these frequency bands shall also require coordination with the
neighbouring countries within the coordination zones of 50 kilometres
from each neighbouring countries.
8.3 Note that the above coordination distance at the border areas is
continuously being reviewed with the neighbouring countries and
may be updated from time to time.
8.4 Technical analysis shall be carried out by the Commission before AA
is issued. AA for FWA services is issued based on station location to
provide service to a specific geographical area. Operator-to-operator
coordination at the subject geographical area and its boundaries may
be required to avoid interference.
8.5 In the event of any interference, the Commission will require an
operator-to-operator coordination to be carried out. In the event the
interference remains unresolved after 24 hours, the matter may be
escalated to the Commission for resolution. The Commission will
decide the necessary modifications and schedule of modifications to
resolve the interference. The Commission shall be guided by the
interference resolution process as shown in Appendix D.

of an administration deploying or planning to deploy land
mobile radars in this band, unless prior agreement has
been obtained.
For earth stations within the fixed-satellite service having an
