Method and system for cellular communication with centralized control and signal processing

Image Number 4 for United States Patent #6016426.

A cellular system includes wide band digital signal processing at a central office that is connected to one or more cellular sites by optical fiber cables. Data signals are exchanged between the cell sites and the central office using intensity modulated optical data signals. Control of call supervision and handling is consolidated in the central office to enable dynamic variation of wireless service reception and transmission capabilities at a cell site in response to changing demands for wireless service. Each antenna at a cell site may receive and transmit an assigned RF bandwidth using any frequency within that band. The central office processes the entire received spectrum for controlling detection and transmitting range, RF carrier frequency and transmit power level for an active channel link established between a cellular station and the system in a cell site.
