Page 31: Overview
Digital Modulation Technique The MTM700 is a 380-430 MHz or 806-870 MHz mobile that can operate in dispatch mode. It uses two digital technologies: π/4 DQPSK and Time Division Multiple Access (TDMA). π/4 DQPSK is a modulation technique that transmits information by altering the phase of the radio frequency (RF) signal.
