Abstract
To provide a technique to simplify a configuration of a wireless communication apparatus that determines a position of a communication terminal. The wireless communication apparatus includes a wireless communication unit and a controller. The wireless communication unit is mounted on a vehicle. The controller switches, in stages, a strength level of a sending signal transferred by the wireless communication unit by radio. In addition to this, the controller determines, based on the strength level and the presence or absence of an answering signal transferred from a communication terminal that has received the sending signal to the wireless communication unit by radio, the position of the communication terminal.
