Abstract
A method for adjusting a power level in a communications network which includes a first plurality of signal-transmission-elements adapted to receive signals coupled to a second plurality of signal-transmission-elements adapted to transmit the signals, the method including de-activating at least some of the first plurality so that the signals are not received in the first plurality and de-activating at least some of the second plurality so that the signals are not transmitted from the second plurality. The method includes injecting a reference signal having a predetermined injected power level at the first plurality, receiving the reference signal at the second plurality, measuring a received power level of the reference signal at the second plurality, comparing the injected and received power levels, and, responsive to the comparison, setting a gain of at least one of the signal-transmission-elements comprised in the first and second pluralities.
