Abstract

Abstract A managing apparatus constructs a database for each network-connected apparatus. Each network-connected apparatus receives ID electric waves transmitted from at least three PHS base stations located at different places, and transmits the amplitudes of the received electric waves and IDs to the managing apparatus. The managing apparatus computes the positions of each network-connected apparatus based on the IDs and amplitudes of the electric waves received from each network-connected apparatus and position of the PHS base stations, and stored the position of each network-connected apparatus in the database.
