초록 ▼

A signal repeating system for a wireless network includes signal repeating circuitry defining an uplink path for processing signals repeated between endpoints. The signal repeating circuitry includes circuitry for selectively varying at least one parameter of the signals that are processed in the uplink path. Circuitry evaluates how signals received in the uplink path of the signal repeating system respond to the variation of the signal parameter. Processing circuitry is configured for comparing a signal associated with the variation of the signal parameter with the evaluated response to determine if the variation causes a change in the uplink path signal response for detecting traffic in the uplink path.
