METHOD FOR POSITIONING BASED ON WIRELESS RECEIVED SIGNAL STRENGTH

摘要

PURPOSE: A location tracing method based on wireless receiving intensity is provided to determine a location by setting the weakest signal detected on a current location as a feature point. CONSTITUTION: A location tracing system stores AP(Access Point) information collected on an exploration location in a database(S201). The system forms a radio map. If sole location information is obtained by comparing MAC(Medium Access Control) information currently collected with location information in the database(S202,S203). If A plurality of locations are detected, the system performs calculation for checking whether the currently collected information is in information scope in the database by using signal intensity information and MAC information detected for the locations(S204).
