  • Determining distance between nodes
    Patent number: 8441620
    Abstract: A first node in a wireless network transmits a periodic pilot signal to a second node. The second node receives the periodic pilot signal and retransmits the signal back to the first node. The retransmitted pilot signal includes a phase adjustment in view of an internal processing delay at the second node. The phase adjustment involves matching a phase of the retransmitted pilot signal to a phase of the received pilot signal. The first node measures a roundtrip delay of the pilot signal and the distance between the nodes is computed based at least on the measured roundtrip delay.
