A system and method for providing a particular wireless communication signal appearing within an antenna beam to a cellular base station to the exclusion of other communication signals also appearing within the antenna beam is disclosed. Preferably multiple narrow antenna beams are utilized to target a communication unit sourcing the particular communication signal. Signals provided by these multiple narrow beams are filtered to exclude undesired communication signals appearing therein and then are provided to select inputs of the cellular base station. Preferably the system of the disclosed invention is adapted to substantially universally couple to various cellular base station configurations.

Universal wideband switchless channel selector

A system and method for accurately determining the position of a mobile unit operating within a predefined service area is disclosed. Three embodiments of the present invention are disclosed which teach the use of one, two and three narrow beam base transceiver stations in the determination of a mobile unit's position. Where one base station is utilized, an information map of signal attributes is used in the position determination. Where two and three base stations are used, signal strength measurements in combination with the time difference of arrival of a signal at the various base stations are used in the position determination.

System and method of determining a mobile station's position using directable beams

A system and method are disclosed for independently adjusting the forward channel power level of each time division burst period of a frame of a time divided signal. The disclosed invention teaches the splitting of the time divided signal for provision to independently controllable circuits associated with each burst period of the frame. Each independently controllable circuit includes a controllable attenuator/amplifier and switching device. The attenuator/amplifier is operated to adjust the power level of its associated burst period to a predetermined magnitude. Thereafter, the switching device operates to direct each power adjusted burst period to be transmitted within a predetermined beam of a multi-beam antenna array.
