| description | This position estimation system comprises a first wireless node for forming a wireless area; second wireless nodes which move within the wireless area; a plurality of third wireless nodes which are provided within the wireless area; and a position estimation device which estimates the position of the second wireless nodes on the basis of information indicating wireless reception quality at the third wireless nodes and the second wireless nodes. The position estimation device determines, for each of section areas, and on the basis of information pertaining to time resource capacity for wireless communication directed towards second wireless nodes, section areas which collect, in place of the first wireless node, information containing wireless reception quality at the second wireless nodes, and transmits, to one of third wireless nodes provided in the determined section area, and instruction to collect wireless reception quality at second wireless nodes within said section area. |
