Abstract: Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response. In another aspect, a non-duplexer isolator sub-system can include an active mitigation sub-system.

Abstract: In an embodiment, an antenna array includes at least first and second antenna rings. The antennas in the first antenna ring are each spaced apart by approximately a first distance from a center of the first antenna ring. And the second antenna rings is approximately concentric and coplanar with the first antenna ring, and each antenna of the second antenna ring is spaced approximately a second distance from the center. For example, the antennas of the first antenna ring are spaced apart by half of a first wavelength corresponding to a first frequency of a frequency range over which the antenna array is designed to operate, and the antennas of the second antenna ring are spaced apart by half of a second wavelength corresponding to a second frequency of the frequency range.

Abstract: Certain aspects involve power management subsystems for a distributed antenna system (“DAS”) or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.
