A wireless relay mitigates cross-relay interference when serving wireless user devices. A network transceiver detects wireless access points and determines signal strengths for the wireless access points. The network transceiver transmits test signals to the wireless access points and directs a user transceiver to detect interference levels during the test. The network transceiver uses the interference level reported by user transceiver to calculate the interference level it would receive from the transmitter of user transceiver with a certain algorithm. The network transceiver selects wireless access points based on their signal strength and calculated cross-relay interference levels. The network transceiver exchanges user data with the selected wireless access points. The user transceiver exchanges the user data with the wireless user devices.
