Zusammenfassung: | A method of determining distances between communication nodes. The method includes transmitting an initial communication frame from a first node to at least one second node. The initial communication frame includes a frame preamble, first data and a first switch point. The method further includes synchronizing a local clock of the at least one second node based on the frame preamble. Switching the at least one second node to a transmitting node based on the received switch point. Transmitting a subsequent communication frame from the at least one second node to the first node. The subsequent communication frame includes a ranging preamble, second data and a second switch point. The method continues by synchronizing a local clock in the first node based on the ranging preamble from the at least one second node and determining the range between the first node and the second node based on the ranging preamble. |
