  • Distributed antenna system with improved uplink leveling
    Patent number: 10805818
    Abstract: Uplink leveling systems and methods for a distribution antenna are provided. An uplink leveling system includes at least one communication path between a base station point of interface and a remote antenna unit. A broadband measurement detector is communicatively coupled to measure signal power in the at least one communication path at the base station point of interface. A signal measurement receiver is communicatively coupled to measure signal power in the at least one communication path. A test signal generator is configured to generate a test signal in the at least one communication path in an uplink. At least one controller is configured to level the communication path in the uplink direction based at least in part on measurements by the broadband measurement detector and the signal measurement receiver in response to the generated test signal by the test signal generator.
