1. A method for controlling gain in a wireless repeater, the method comprising:

  • receiving an input signal at a receiving antenna of the repeater, the input signal being a sum of a remote signal to be repeated and a feedback signal resulting from a feedback channel between the receiving antenna and a transmitting antenna;

    transmitting an output signal on the transmitting antenna, the output signal being an amplified input signal;

    providing one or more gain control metrics, the gain control metrics being indicative of a loop gain of the repeater;

    measuring the one or more gain control metrics; and

    adjusting a variable gain of the repeater using a gain adjustment step size being a function of at least the loop gain of the repeater as measured by the one or more gain control metrics.
