LOCATION ESTIMATION SYSTEM, WIRELESS COMMUNICATION APPARATUS, PROGRAM, LOCATION ESTIMATION METHOD, AND INFORMATION SERVER

摘要

PROBLEM TO BE SOLVED: To provide a location estimation system, a wireless communication apparatus, a program, a location estimation method, and an information server.;SOLUTION: The wireless communication apparatus 20 is provided with a storage section 232 for storing location information of a base station and identification information of the base station in association with each other, a receiving section for receiving a wireless signal including the identification information of the base station transmitted from the base station, and a location estimating section 224 for estimating a location of the wireless communication apparatus based on the wireless signal and the location information stored in the storage section. In the storage section, the location information of a first base station within a first range is represented by using a first discrete value in which the location of the first base station is quantized by a first quantization number while the first range is a quantization range, the location information of a second base station within a second range which is narrower than the first range and higher in basic station density than the first range is represented by using a second discrete value in which the location of the second base station is quantized by a second quantization number less than the first quantization number.;COPYRIGHT: (C)2009,JPO&INPIT
