发明名称 WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION TERMINAL, AND DISTANCE CALCULATION METHOD
摘要 PROBLEM TO BE SOLVED: To provide a wireless communication system that calculates a distance between a wireless communication terminal and a first base station apparatus, provided that the wireless communication terminal can receive signals from the first base station apparatus and a second base station apparatus having a radio communicable distance shorter than the first base station apparatus, even when location information of each base station apparatus is unknown, and to provide the wireless communication terminal and a distance calculation method. SOLUTION: When the wireless communication terminal 300 receives signals from the first base station apparatus 100 and the second base station apparatus 200 having a radio communicable distance shorter than the first base station apparatus 100, it is assumed that the distance between the wireless communication terminal 300 and the second base station apparatus 200 is zero to calculate the distance between the wireless communication terminal 300 and the first base station apparatus 100.
