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.

1. A wireless communication system for transmission of data, voice, video and/or multimedia information to allow individual subscribers in an area of service access to a telecommunications network comprising:a plurality of subscriber interfaces, each of the subscriber interfaces connected to at least one item of customer premise equipment, the customer premise equipment capable of transmitting and/or receiving data, voice, video and/or multimedia signals, each of the subscriber interfaces including, a modulator for modulating data, voice, video and/or multimedia signals from the customer premise equipment into a form suitable for transmission over the wireless communication system, and a demodulator for demodulating a signal received over the wireless communication system into a data, voice, video and/or multimedia signals; a base station interface connecting the wireless communication system to the telecommunications network, the base station interface including, a modulator for modulating data, voice, video and/or multimedia signals from the telecommunications network into a form suitable for transmission over the wireless communication system and a demodulator for demodulating a signal received over the wireless communication system into a form suitable for transmission over the telecommunications network; a first frame structure for communicating information over the telecommunications network, the first frame structure having a first frame length; a second frame structure for communicating information over the wireless communication system, the second frame structure having a second frame length, the second frame length being smaller than the first frame length; and a fragmentor for dividing the first frame structure into frame fragments capable of being transmitted over the wireless communication system using the second frame structure, the frame fragments having a third frame length having a maximum value equal to the second frame length, wherein the information communicated by the second frame structure is communicated between the base station and the subscriber interfaces using time division duplexing.
