Abstract
A system for distributing radio frequency signals in a wireless communication network that provides an economical method of establishing and then later enhancing network coverage and capacity. The system centrally deploys Base Transceiving System (BTS) equipment and distributes their signals through a fiber network to individual cable microcell integrators (CMI) associated with the individual cell sectors of the system. The CMIs contain filtering equipment that permit them to be assigned in simulcast groups, depending upon the desired network capacity. For example, in an initial build out situation, a large number of CMIs operate at a common carrier frequency, modulation code, and/or code phase. As network demands increases, additional capacity is provided by reprogramming filters and/or signal processors in the CMIs. The approach results in high utilization of centrally located BTS equipment, avoids the need to re-engineer or redeploy additional RF equipment after an initial design phase, and has an added benefit of improved backhaul trunking efficiency while avoiding the need to deploy both fiber and cable physical media at the remove sites.
