PROBLEM TO BE SOLVED: To provide a method of determining a distance estimate between a mobile device and a wireless transceiver communicating with the mobile device by at least one multi-carrier signal.SOLUTION: The method includes: receiving at least one multi-carrier signal; selecting at least one carrier signal from the at least one multi-carrier signal; measuring a signal characteristic of the at least one carrier signal from the at least one multi-carrier signal; and determining the distance estimate between the mobile device and the wireless transceiver on the basis of at least partially the signal characteristic. 【課題】モバイル・デバイスと、少なくとも１つのマルチ・キャリア信号でモバイル・デバイスと通信している無線トランシーバとの間の距離推定値を判定する方法を提供する。【解決手段】少なくとも１つのマルチ・キャリア信号を受信することと、少なくとも１つのマルチ・キャリア信号から、少なくとも１つのキャリア信号を選択することと、少なくとも１つのマルチ・キャリア信号から、少なくとも１つのキャリア信号の信号特性を測定することと、少なくとも部分的に信号特性に基づいて、モバイル・デバイスと無線トランシーバとの間の距離推定値を判定することとを含む。【選択図】図６
