MCMC MTSFB TC GXXX:2021 TECHNICAL CODE PREDICTION AND MEASUREMENTS OF EMF EXPOSURE FROM TERRESTRIAL RADIO AND TELEVISION BROADCASTING TRANSMITTER STATIONS Developed by Registered by Registered date: © Copyright 2021 MCMC MTSFB TC GXXX:2021 Development of technical codes The Communications and Multimedia Act 1998 (‘the Act’) provides for Technical Standards Forum designated under section 184 of the Act or the Malaysian Communications and Multimedia Commission (‘the Commission’) to prepare a technical code. The technical code prepared pursuant to section 185 of the Act shall consist of, at least, the requirement for network interoperability and the promotion of safety of network facilities. Section 96 of the Act also provides for the Commission to determine a technical code in accordance with section 55 of the Act if the technical code is not developed under an applicable provision of the Act and it is unlikely to be developed by the Technical Standards Forum within a reasonable time. In exercise of the power conferred by section 184 of the Act, the Commission has designated the Malaysian Technical Standards Forum Bhd (‘MTSFB’) as a Technical Standards Forum, which is obligated, among others, to prepare the technical code under section 185 of the Act. A technical code prepared in accordance with section 185 shall not be effective until the Commission pursuant to section 95 of the Act registers it.
