Abstract: An communication system is disclosed which improves upon known distributed antenna systems and known signal distribution systems which rely on bidirectional amplifiers. The disclosed communication system incorporates an integrated base transceiver station into remote units or bidirectional amplifiers provided proximate a coverage area, where the coverage area is remote or closed off from a base coverage area for a distant signal source such as a base transceiver station.

Abstract: An intelligent distributed antenna system is disclosed which improves upon known distributed antenna systems particularly with respect to identifying failures or anomalies in the system. The disclosed system includes a signal source, a master unit, and one or more remote units each connected to antennas for transmitting radio frequency signals to terminal units and each connected to the master unit through fiber. The remote units, the master unit, or both may include power signal readers. The remote units may be configured to determine a point of failure in the system based on the power measured from reflected signals. The master unit can be in communication with the remote units to generate alarms and reports as well as to control the system in response to detection of a failure or anomaly.

Abstract: The present invention relates to a programmable filtering system that allows the telecommunications receivers to maintain and improve their reception quality against high levels of noise floor and/or the presence of unwanted signals. The filtering system is portable and of a compact size, similar to the telecommunications receiver.
