Abstract :
This article shows that the wireless local loop (WLL) may not necessarily provide more capacity than mobile cellular systems if an FDMA or TDMA system is used. CDMA has proven to have higher capacity than the other multiple access schemes due to the nature of CDMA systems. In industrial countries, the requirements of WLL are quality and service features. In developed countries, the requirement is a low-cost high-capacity system, even if voice quality must be sacrificed. Therefore, the system design aspects are different
