MONITORING NON-SUPPORTED WIRELESS SPECTRUM WITHIN COVERAGE AREAS OF DISTRIBUTED ANTENNA SYSTEMS (DASS)

摘要

Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head-end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.

主权项

1. An apparatus connected to at least one remote unit of a wireless system for monitoring non-supported wireless spectrum within a coverage area of the wireless system comprising:
at least one antenna configured to receive one or more electromagnetic signals; a listening module connected to the at least one antenna comprising:
at least one input configured to receive the electromagnetic signals from the at least one antenna;at least one output configured to transmit the electromagnetic signals over at least one optical uplink path of the wireless system to head-end equipment of the wireless system; andat least one listening path disposed between the at least one input and the at least one output and configured to:
pass a non-supported radio band different than a supported radio band of the wireless system to the at least one output, andprevent at least one radio band that includes the supported radio band of the wireless system from being passed to the at least one output.
