Abstract: Wireless hand-held devices, such as cellular phones, with a second network capability, such as 802.11 network connectivity are used in the disclosed technology. These devices detect surrounding SSIDs (service side identification) transmitted from 802.11 networks, send the SSIDs to a server via the cellular connection, and receive back a message to be displayed. The message sent is dependent upon prior SSIDs detected and/or prior messages already sent. In embodiments, wireless transmitters which transmit SSIDs are of varying power, such that a stronger signal is detected in a broader area, and a weaker signal in a smaller area within the broader area. As such, locations and even paths of travel may be determined.
