Abstract
A system and a method provide a communication network using time-division multiplexing and a single frequency to achieve maximum utilization of the spectrum and the available bandwidth. In one embodiment, time-division multiplexing is used to share the bandwidth between a wide-area transmitter, operating over a designated service area, and numerous simultaneous channels using the same frequency between local base stations and their associated user terminals. Each local base station is assigned a different non-overlapping portion of the designated service area. The communication network can accommodate devices of different data rates.
