Investigating the Reverse Link Erlang Traffic Capacity of a Power Controlled Wireless Local Loop Cdma System

Abstract

In this paper, the reverse link Erlang traffic capacity of a power controlled CDMA based Wireless Local Loop (WLL) voice system equipped with high gain directional antennas at either the base station or users' houses is investigated. It is shown that the Erlang traffic capacity of CDMA based WLL system is several times that of mobile cellular CDMA system and conventional multiple access systems, such as FDMA and TDMA based systems. Finally the study of Telecom Egypt WLL CDMA2000-1xRTT network is examined as a case study.
