This TS specifies the requirements for the CTS-Fixed Part (CTS-FP) transceiver of the digital mobile cellular and personal communication systems operating in the 900 MHz (P-GSM and E-GSM) and 1800 MHz band (GSM 900 and DCS 1800), and specifies the Radio subsystem frequency control implemented in the CTS-Fixed Part.
