The invention relates to a distance-measuring system, a distance-measuring device and a distance-measuring method. The distance-measuring system of an embodiment configured to calculate a distance between a first device and a second device based on transmission and reception between the first device and the second device includes a communication section configured to communicate with a first frequency band and/or with a second frequency band different from the first frequency band, a determination section configured to determine whether the first device is located within a predetermined rangeof the second device, and a control section configured to control, when a determination result of the determination section shows that the first device is not within the predetermined range, to perform a distance-measuring operation with the first frequency band, and when a determination result of the determination section shows that the first device is within the predetermined range, to perform adistance-measuring operation with the second frequency band.
一种测距系统、测距装置以及测距方法,实施方式的测距系统为,在第一装置以及第二装置间基于收发来计算上述装置间的距离,具备:通信部,以第一频带以及/或者不同于上述第一频带的第二频带进行通信;判定部,判定上述第一装置相对于上述第二装置是否位于预定的范围内;以及控制部,根据上述判定部的判定结果进行控制,以使得当表示上述第一装置并不位于上述预定的范围内的情况下,使用上述第一频带进行测距运算,当表示上述第一装置位于上述预定的范围内的情况下,使用上述第二频带进行测距运算。
