  • Patent number: 11722207
    Abstract: A service-area repeater for deployment in a service area to provide capacity supplied by a base station located remotely from the service-area repeater includes downlink circuitry to receive, via a donor antenna coupled to the service-area repeater, transformed RF downlink signals transmitted from the base station or a base-station repeater, the base station transforming original RF downlink signals or the base-station repeater transforming original RF downlink signals received from the base station to produce the transformed RF downlink signals. The downlink circuitry includes a signal transformation circuit to de-transform the received transformed RF downlink signals to generate non-transformed downlink signals and a frequency correction circuit to apply a frequency correction to the downlink signals to produce corrected downlink signals. The downlink circuitry wirelessly transmits the corrected downlink signals via a coverage antenna to user equipment in the service area.

  • Patent number: 11368870
    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.
