Abstract

A radio fingerprint device implements a radio fingerprint map construction and location tracking method. In this method, the radio fingerprint device receives, from a manager terminal device, radio environment information varying for a predetermined time at a specific referential position in a particular indoor area so as to create a radio fingerprint map. Then the radio fingerprint device extracts a periodic pattern from the received radio environment information, and stores, in the radio fingerprint map, the extracted periodic pattern as a radio fingerprint feature of the specific referential position.
