Abstract: An example method comprises receiving, by a first PHY of a first transceiver, a timing packet, timestamping, by the first transceiver, the timing packet and providing the timing packet to a first intermediate node, determining a first offset between the first intermediate node and the first transceiver, updating a first field within the timing packet with the first offset between the first intermediate node and the first transceiver, the offset being in the direction of the second transceiver, receiving the timing packet by a second transceiver, the timing packet including the first field, information within the first field being at least based on the first offset, determining a second offset between the second transceiver and an intermediate node that provided the timing packet to the second transceiver and correcting a time of the second transceiver based on the information within the first field and the second offset.

Abstract: An example system comprising a first transceiver configured to receive a request airframe from a second transceiver over a wireless link, the request airframe including a first timestamp indicating a first time T1 timestamp a second time indication indicating a second time T2 that the request airframe was received, generate a respond airframe and including a third time indication indicating a third time T3 that the respond airframe is transmitted to the second transceiver, transmit the respond airframe to the second transceiver, provide a timestamp information request to second transceiver, receive a timestamp information response, the timestamp information response including a fourth time indication indicating a fourth time T4, calculate a counter offset using the first time, second time, third time and fourth time as follows: counter   offset = ( TS   1 + TS   4 - TS   3 - TS   2 ) 2 , calculate a phase offset based on the counter offset, and correct a phase of the first transceiver.
