MONITORING NON-SUPPORTED WIRELESS SPECTRUM WITHIN COVERAGE AREAS OF DISTRIBUTED ANTENNA SYSTEMS (DASS)
First Claim
1. A wireless communication system, comprising:
- a plurality of remote units optically coupled to a source of optical downlink communications signals and configured to provide optical uplink communications signals, each remote unit comprising at least one antenna configured to receive electromagnetic signals from a respective coverage area;
at least one listening module connected to at least one of the plurality of remote units, the at least one listening module comprising;
at least one input configured to receive the electromagnetic signals from at least one of the antennas;
at least one output configured to transmit the electromagnetic signals over at least one uplink path of the wireless system; and
at 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, and to pass at least one supported radio band to the at least one output; and
a monitoring module configured to receive the non-supported radio band passed by the at least one listening path of the listening module.

Abstract
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.
