Micro-channel bank for providing voice, data, and multimedia services

摘要

A method and system for assigning multiple wireless communication channels in 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 provides for removing a number of channels, called a bank, from a larger pool of channels. The removed bank of channels are then assigned in ways to provide subscribers with both voice and digital data service. The system is designed to support POTS (Plain Old Telephone), ISDN, and direct data service in a point to multi-point configuration. The system 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.
