ABSTRACT:
A method and system for implementing an air interface for a Time Division Duplex (TDD) Code Division multiple Access (CDMA) wireless local loop system that utilizes unique embedded concentrated access and embedded data access in a Wireless Local Loop (WLL) is described. The method and system further provides for dynamic pool sizing of the access channels. The interface is designed to support POTS (Plain Old Telephone), ISDN, and direct data service in a point to multi-point configuration. The interface is inherently flexible so as to provide Enhanced Bandwidth and quality of service (QOS) via CDMA. Channel concatenation (multi-code modulation) provides a multiplicity of channels. The system utilizes frequency division duplex (FDD) operation so as to double capacity. The system further utilizes scaleable architecture for bandwidth expansion and higher data rate services.
