Detail of GB/T 22450.1-2008

Introduction of GB/T 22450.1-2008

1 Scope This Part of GB/T 22450 specifies the requirements for the electromagnetic compatibility (EMC) of mobile station and ancillary equipment of Phase 1 and Phase 2 GSM 900 MHz and DCS 1800 MHz digital cellular telecommunication systems that transmit and receive voice and/or data, including the measurement methods, frequency range, limits and performance criteria. This Part is applicable to portable and vehicular mobile stations, also applicable to those mobile stations that are powered by AC power supply and used at fixed position as well as the data terminals of various GSM 900 MHz and DCS 1800 MHz digital cellular telecommunication systems. 2 Normative References The following documents contain provisions which, through reference in this Part of GB/T 22450, constitute provisions of this Part.
