发明名称 Locating a WLAN station using signal propagation delay
摘要 A wireless network device including: a first RF transceiver module configured to (i) for a predetermined number of times, transmit a data frame to a second RF transceiver module, and (ii) for each data frame transmitted to the second RF transceiver module, receive an acknowledgement frame from the second RF transceiver module after a respective delay period; a timing module configured to generate a timer value corresponding to an accumulated delay period, wherein the accumulated delay period corresponds to each of the respective delay periods; and a control module configured to (i) determine the predetermined number of times that the first RF transceiver transmitted the data frame to the second RF transceiver based on a resolution of the timing module, and, (ii) determine an actual delay period based on (a) the timer value and (b) the predetermined number of times.
