Patent ID: 10834598

Abstract:
One embodiment of the disclosure relates to radio frequency (RF) communication channel reconfiguration in remote antenna unit (RAU) coverage areas in a distributed antenna system (DAS) to reduce RF interferences. In this regard, a spectrum optimization unit dynamically reconfigures RF communication channels employed by RAU coverage areas in a DAS to reduce or avoid adjacent-channel and/or co-channel RF interferences. Each of the RAU coverage areas provides a respective sniffed RF signal to the spectrum optimization unit. The spectrum optimization unit analyzes the respective sniffed RF signal to determine a respective lesser-interfered RF communication channel for an RAU coverage area and dynamically reconfigures the RAU coverage area to communicate on the respective lesser-interfered RF communication channel. By dynamically reconfiguring the RAU coverage areas to communicate on respective lesser-interfered RF communication channels, it is possible to reduce or avoid RF interferences to provide improved capacity, throughput, and coverage in the DAS.
