This document provides specifications for GSM/GPRS, TDMA, and AMPS cellular standards. It includes information on frequency bands, modulation, sensitivity, dynamic range, selectivity, blocking characteristics, phase noise, and channel filter performance. Key specifications listed are frequency bands of 869-894 MHz or 1930-1990 MHz, modulation schemes of GMSK, DQPSK and FM, and sensitivity levels below -102 dBm for GSM/GPRS and -110 dBm for TDMA.
