摘要： An active repeater device including a first antenna array, a controller, and one or more secondary sectors receives or transmits a first beam of input RF signals from or to, respectively, a first base station operated by a first service provider and a second beam of input RF signals from or to, respectively, a second base station operated by a second service provider. A controller assigns a first beam setting to a first group of customer premises equipment (CPEs) and a second beam setting to a second group of CPEs, based on one or more corresponding signal parameters associated with the each corresponding group of CPEs. A second antenna array of the second RH unit concurrently transmits or received a first beam of output RF signals to or from the first group of CPEs and a second beam of output RF signals to the second group of CPEs.

The controlled plurality of reflector devices transmit a plurality of RF signals in a specified direction and a specified location of a second RF device within transmission range of the controlled plurality of reflector devices. The plurality of RF signals are transmitted in the specified direction and the specified location of a second RF device based on a request for signal cancellation. The request for the signal cancellation is based on a noise from the second RF device and the plurality of RF signals are cancelled in the specified direction and the specified location of the second RF device.
