METHOD OF GEOGRAPHICALLY TAGGING RADIO ACCESS POINT, METHOD OF GENERATING GEOGRAPHIC CODE OF ACCESS POINT, AND METHOD OF DECODING GEOGRAPHIC CODE FOR POSITIONING

摘要

PROBLEM TO BE SOLVED: To easily and inexpensively detect the position of a user.

SOLUTION: A system for geographically tagging network access points is configured to provide location information as part of their beacon. Each access point provides a service set identifier (SSID), and the SSID includes an encoded value that represents the location of the access point. The use of an encoded location value in the SSID of the access point is particularly advantageous in that it does not require any additional hardware be added to the access point or the portable computer. In addition, locations can be determined by any portable device without establishing connections to the access point. The portable computer devices are adapted to receive the beacon, extract the location information from the beacon and decode the beacon (positional information).
