ABSTRACT:
A wireless network device comprises a first RF transceiver module and a control module. The first RF transceiver module transmits a first data frame to a second RF transceiver module and receives a first acknowledgement (ACK) frame from the second RF transceiver module after a first delay period. The first RF transceiver module transmits a second data frame to the second RF transceiver module and receives the second ACK frame from the second RF transceiver module after a second delay period. The control module communicates with the first RF transceiver module and determines a total delay period based on the first and the second delay times. The control module determines an actual delay period between the first and the second RF transceiver modules based on the total delay period.
