This cellular mobile radio telephony is a new and attractive area of current interest. This paper provides a general idea of the cellular system with particular emphasis on the PRMA protocol for digital speech transmission. This paper shows that PRMA is a suitable protocol for the transmission of speech, as it increases the channel capacity by allowing more than one terminal to share a channel. This is done by multiplexing speech terminals in a TDMA fashion while keeping the implementation easier.
