This paper discusses the possibility of using the Packet Reservation Multiple Access (PRMA) protocol to provide spatially dispersed voice and data user terminals wireless access to a base station over a common short‐range radio channel. The case of ideal radio channel propagation conditions as well as that of non‐ideal and non‐stationary radio channel propagation conditions is considered. A modified PRMA (MPRMA) protocol is proposed in order to enhance system performance under heavy traffic load conditions. A technique to break off the possibility of accessing the common radio channel by a data user terminal is also discussed to avoid unsuccessful transmission of data packets during poor channel conditions. Performance comparisons with the standard PRMA protocol clearly point out a better behavior for the proposed MPRMA protocol.
