Monitoring non-supported wireless spectrum within coverage areas of distributed antenna systems (DASs)
First Claim
1. A method of monitoring non-supported wireless spectra within a coverage area of a wireless system, the method comprising:
- receiving, at a plurality of antennas, one or more electromagnetic signals;
receiving, at a listening module connected to at least one of a plurality of remote units, the one or more electromagnetic signals from at least one of the plurality of antennas;
passing the one or more electromagnetic signals in a non-supported radio band different than a supported radio band of the wireless system to an output of the listening module; and
transmitting the non-supported radio band from the output of the listening module over a communications medium of the wireless system, whereinthe listening module comprises at least one mixer, at least one amplifier, and at least one filter configured to pass the non-supported radio band.

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.
