Abstract: For use in a wireless network having geographicallydistributed base stations that serve wireless terminals, a system for, and method of, improving an operation of the wireless network. In one embodiment, the system includes: (1) a signal quality determination circuit that determines a relative quality of signals communicated between one of the wireless terminals and a set of base stations within range of the one of the wireless terminals and (2) a base station selection circuit, coupled to the signal quality determination circuit, that selects a base station in the set to serve the one of the wireless terminals based on the relative quality of signals.

Abstract: Disclosed is a multiple-beam transmitting system (100) for use in a wireless telecommunication system, including a radio transmitter assembly (104), which can be situated at the bottom of a base station tower, and a transmitter subassembly (102) that can be situated atop the base station tower. The radio transmitter assembly is operative to modulate and frequency translate a plurality of input information-bearing signals. The signals are then combined to form a first FDM signal, which can then be routed to the transmitter subassembly via a single FDM cable (110) running up the tower. The transmitter subassembly (102) includes a power splitter (120) for splitting the first FDM signal into a plurality of second FDM signals and a plurality of frequency translators, (T1 to TM ), each for frequency translating one of the second FDM signals. Each frequency translator thereby places at least one of the information-bearing signals within a predetermined translated frequency band. A multiple-beam-antenna (150) radiates a plurality of antenna beams, with each antenna beam transmitting at least one of the information-bearing signals placed by an associated frequency translator within the translated frequency band. A multiple beam receiving system can be employed to receive incoming signals from wireless terminals.
