Performance of fixed wireless access with cdma2000 1xEV-DO

Fixed and portable wireless Internet access is becoming an important segment for the wireless industry. 1xEV-DO, also known as IS-856, has been designed to offer increased user experience and high capacity packet data services on cdma2000 networks. The initial set of 1xEV-DO performance results in the literature has focused on mobile environments. In this paper, we address some of the fixed wireless aspects and the corresponding impacts on system performance. A network level simulation of both forward and reverse links including physical and MAC layer details of 1xEV-DO is used to quantify performance. In addition to average throughput per sector, we quantify the user performance on both links as a function of total attenuation. This provides insight on how performance varies within the coverage area - a very important aspect for fixed access. Moreover, we also show how different forward link data schedulers can be used to tradeoff system capacity for a more uniform performance regardless of the terminal distance to the serving base station.
