Abstract
Abstract A wireless access architecture, having redistributed wireless access functions, comprises a plurality of cell sites connected to a main switching point. The cell sites communicate with cellular users within their respective cell site areas and comprise a communication segment for exchanging communication signals with the cellular users. The main switching point controls the communication with the cellular users and the communication segment and includes a processing segment for processing the communication signals from the cell sites. The processing segment includes a segment for modulating and demodulating the communication signals, and a segment for bit stream processing the communication signals.
