A repeater system includes a first repeater device to receive a first beam of radio frequency (RF) signal from a first network node, and a second repeater device to receive a second beam of RF signal from the first network node. The first repeater device synchronizes and controls the second repeater device to concurrently provide the first beam and the second beam of RF signal to a second network node. A plurality of measurements associated with network nodes and repeater devices is acquired. A plurality of signal parameters is selected at the first and second repeater devices for a first beam and a second beam of RF signal, respectively, such that a cross-leakage of first beam on the second beam of RF signal and vice-versa at the second network node is reduced and the gain and a phase of first beam and the second beam of RF signal is adjusted.
