Abstract: A system for detecting whether an antenna has been disconnected from a coverage extension system is disclosed. The system for detecting disconnected antennas includes an antenna receiving signals from a base station and noise from the environment; a coupler; a transceiver; a power sensor to measure the power intensity of the noise; a controller; and a wired connector, electrically connecting the output of the antenna to the coupler, for carrying said signals and white noise from the antenna to the coupler. The coupler outputs part of the signal and noise to the power sensor and another part of the signal and noise to the transceiver. The controller detects changes in the power intensity of the noise to detect whether the antenna has been disconnected.

Abstract: A coverage extension antenna system includes a signal booster or a DAS. The signal booster or DAS includes a set of demodulators that convert incoming signals to baseband, and includes a set of modulators that modulate the baseband signals before transmitting the modulated signals to a base station or terminal equipment.

Abstract: A communication system includes a signal source for transmitting downlink signals and receiving uplink signals to and from an indoor signal coverage area; and a distributed antenna system interposed between the signal source and the indoor signal coverage area. The distributed antenna system includes an antenna monitoring unit connected to at least one service antenna through a distribution network. The at least one antenna transmits and receives the downlink signals and the uplink signals to and from at least one terminal unit within the indoor coverage area. The antenna monitoring unit includes an RFID transceiver that communicates with at least one RFID tag attached to the at least one antenna and detects the location of a point of anomaly with respect to that one antenna when a signal from the at least one RFID tag is not received by the RFID transceiver, or when a power level measured by the RFID tag and reported back to the RFID transceiver falls below a predetermined threshold level.

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: 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: A system for monitoring passive components of a passive distributed antenna system is disclosed. The system includes a bi-directional amplifier, a public safety monitor coupled to and in communication with the bi-directional amplifier, and at least one smart node coupled to and in communication with the public safety monitor. The at least one smart node is positioned within the passive distributed antenna system and includes a processor, connected to or coupled to a spectrum analysis module configured to monitor signal characteristic information of at least one radio frequency signal passing through the passive distributed antenna system. The processor is configured to transmit the signal characteristic information to the public safety monitor and the public safety monitor generates system performance information based on a signal at the bi-directional amplifier and the transmitted signal characteristic information.

Abstract: A system for managing an uplink amplification chain in a coverage extension system is disclosed. The system includes a transceiver unit; an uplink amplification chain including one or more amplifiers; and an ON/OFF mechanism that turns ON or OFF the uplink amplification chain totally or partially. The uplink amplification chain is located within the transceiver unit. The ON/OFF mechanism receives from an external source instructions directing the ON/OFF mechanism when to turn ON or OFF the amplification chain totally or partially.
