Performance analysis of a time division duplex broadband fixed wireless access system in the 5 GHz U-NII bands

In this paper we analyze the performance of a point-to-multipoint (PTM) time division duplex (TDD), time division multiple access (TDMA) broadband fixed wireless access (FWA) system in the 5 GHz U-NII Band. After a brief background on the 5 GHz radio and then the TDD/TDMA FWA system concept, we characterize throughput and system utilization, obtained from extensive simulations. Various traffic mixes have been modeled using a modified 3GPP2 traffic model. Additionally, analytical results for end-user performance is compared with the simulations results along with a discussion.
