1. A signal repeating system for a wireless network comprising:

  • at least one first antenna configured for transceiving signals with at least one user equipment device;

    repeating circuitry coupled to the at least one first antenna and defining an uplink path for signals from the user equipment device back to a base station and a downlink path for signals from the base station to the user equipment device, the repeating circuitry including gain circuitry;

    gain control circuitry coupled to the gain circuitry and operable for varying the gain of the repeating circuitry according to a waveform;

    measurement circuitry for measuring the receive power in the uplink path over time from the at least one user equipment device;

    processing circuitry for cross-correlating the inverted gain variation waveform with the measured receive power for determining the existence of traffic from user equipment devices in the uplink path.
