Abstract

A first node of a radio network initiates a mode for finding the range to a second node. The first node transmits to the second node, with the address of the second node, a range finding command, which switches the second node into the range finding mode and controls a sequence. The first node transmits in a transmission time window a first signal, which is received by the second node in an associated reception time window, a first phase value of the first signal being measured. The second node transmits in a transmission time window a second signal, which is received by the first node in an associated reception time window, a second phase value of the second signal being measured. The first frequency is changed by a frequency difference and the second frequency is changed by the frequency difference in a subsequent time window of the sequence.
