The wireless device (100), preferably a wireless tag (100), comprises a first beacon parameter (142) formatted as a mobile phone parameter (42), a second beacon parameter (122) formatted as a base transceiver station parameter (22), and a wireless transmitter (102). The location processing module (50) determines a first range (200) in function of the connected base transceiver stations (10) that detected the first beacon signal (140); and determines a second range (300) in function of the connected mobile phones (30) that detected the second beacon signal (120), the second range (300) being smaller than the first range (200). |
