Abstract

Disclosed herein are exemplary techniques for establishing a direct link independent of an access point and for identifying proximate wireless stations users. The method and method are provided in a wireless network with an access point logically connected to at least a first wireless device and a second wireless device to notify the first wireless device that the second wireless device is in proximity to said first device. The system and method also establish a direct wireless link between a first wireless device and at least one proximate wireless device by identifying a second wireless device within a predetermined proximity of the first wireless device, determining an identity associated with a user of the second wireless device, comparing the identify with a set identities, and notifying the user of a proximity of the user of the second wireless device based on the comparison.
