Abstract
The invention includes additional uses for the SSID of the IEEE 802.11 beacon to include reliable and secure capability encoding. The SSID in the system can be controlled by applications and transmitted with periodic broadcasting or point to point communication, so interoperable communication of application or user preferences/capabilities/membership can be transmitted and quickly determined by peers.

10. A method comprising:
-
receiving, at a first wireless device, a beacon transmitted from a second wireless device, wherein the beacon is transmitted from the second wireless device to the first wireless device through a wireless network that is compliant with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, and wherein the beacon is encoded to include a capability or a preference of the second wireless device; transmitting the service set identifier (SSID) from the first wireless device to a central server, wherein the service set identifier (SSID) is decodable by the central server to retrieve the capability or the reference of the second wireless device as encoded into the service set identifier (SSID); and subsequent to transmitting the service set service set identifier (SSID) from the first wireless device to a central server, receiving, at the first wireless device, the capability or the preference of the second wireless device from the central server. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
