Abstract :
The author investigates the issue of uncorrelated multipath fading on uplink and downlink radio channels which impacts the handoff decision quality of slowly moving users in a CDMA system. Simulation results indicate a resulting capacity reduction by as much as 30% when all the users experience quasistationary, single-path Rayleigh fading. This work is targeted toward understanding the traffic capacity and deployment implications to local exchange networks of wireless technology alternatives that could provide access to those networks.<>
