This article discusses the technology behind digital mobile radios and their advantages over the old two-way analog radios designed only to transmit voice. In addition to providing users with useful tools and data transmission capabilities, digital radios have longer battery life and enhanced voice quality. Two primary digital radio technologies are available in the land-mobile radio (LMR) market, namely, the Time-Division Multiple-Access (TDMA) and the Frequency-Division Multiple-Access (FDMA).
