Abstract

An embodiment of the present invention provides a method of detecting user presence, comprising registering a client associated with the user on a host associated with the user and setting up a wireless communication pairing, wherein while setting up the pairing, the client measures the host wireless communication power and uses it as calibration threshold for distance detection, and wherein the client measures a beacon power of the host radio and when the beacon power is above a threshold, the client is determined to be proximate to the host.
