Abstract :
Computer simulation results are given for two-way transmission quality resulting from portable radio access. Downlink and uplink performance were examined for a range of frequency reuse factors, propagation models and traffic levels. The effect of traffic on the TDMA (time-division multiple access) uplink is given as a function of occupancy. It was found that uplink transmission quality lags behind that of the downlink in moderate to heavy cochannel interference environments, but not unmanageably so
