A method and system for pairing devices comprises transmitting a plurality of communication signals from each of a plurality of devices and setting an initial threshold vector of signal strengths as a current threshold vector of signal strengths for at least one target device selected from among the plurality of devices. The embodiment includes pairing at least one client device with the at least one target device when a measured vector of signal strengths exceeds the current threshold vector of signal strengths and adjusting the current threshold vector of signal strengths according to the pairing between the client device and the target device, thereby adaptively adjusting the current threshold vector of signal strengths.
