Abstract
A method and system for proximity detection, recognition and classification of a wireless local area network (WLAN) enabled device without a WLAN infrastructure. The proximity recognition system monitors WLAN communications at one or more known locations. The proximity of a WLAN device (transmitter) is sensed by examining signal strength received therefrom as the device engages in a sequence of protocol data unit exchanges seeking WLAN association.
