The performance of a speech-data PRMA system in an in-building environment

The performance of an in-building speech-data PRMA system employing frequency reuse is determined via computer simulation. Propagation measurements (at 1.8 GHz) made in the building in which the PRMA system is assumed to operate, are included in the analysis. Significant variations in performance are found to exist over the coverage area. Optimum system performance is obtained by allocating the entire bandwidth to each floor (i.e., complete frequency reuse) and re-transmitting any packets that are corrupted by cochannel interference. This significant result suggests that packet access schemes such as PRMA can provide an alternative to TDMA and CDMA based future wireless networks.
