Abstract

Consider a multi-user, multi-frequency, digital, * a population of half- and full-duplex mobile TDMA, cellular RF packet data system (Figure 1) subscriber units with attached mobile computers. composed of: * full-duplex, stationary base radios operating in conjunction with support infrastructure; and Fig. 1 Cellular RF packet data system Each base station radio controls one or more pairs of RF communication channels. One channel of each pair is designated the inbound channel and the other the outbound channel. To simplify the remaining discussion, we assume each base station radio has only one pair of communication channels. The base station simultaneously transmits on the outbound channel and receives on the inbound channel. Each half-duplex subscriber unit of the population may transmit or may receive on any one communication channel within its range in the sys- tem at any given time. Each full-duplex subscriber unit may do both operations concurrently.
