1.0 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.

2.0 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.

3.3 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.

4.0 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

MCMC SRSP-547 FWA

6

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.

5.0 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.

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.

MCMC SRSP-547 FWA

10

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.

8.6 AA holders are expected to carry on interference mitigation

techniques such as antenna discrimination, tilt, polarization,

frequency discrimination, shielding/ blocking (introduce diffraction

loss), site selection, distance and/or power control in order to

facilitate the coordination of systems.
