Locating a WLAN station using signal propagation delay
First Claim
1. A wireless network device, comprising:
- a first RF transceiver module configured tofor a predetermined number of times, transmit a data frame to a second RF transceiver module, andfor 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 todetermine 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, anddetermine an actual delay period based on (i) the timer value and (ii) the predetermined number of times.

Abstract
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.

10. A method for operating a wireless network device, the method comprising:
-
for a predetermined number of times, transmitting a data frame from a first RF transceiver module to a second RF transceiver module; for each data frame transmitted to the second RF transceiver module, the first RF transceiver receiving an acknowledgement frame from the second RF transceiver module after a respective delay period; generating a timer value corresponding to an accumulated delay period, wherein the accumulated delay period corresponds to each of the respective delay periods; and determining the predetermined number of times based on a resolution associated with the timer value; and determining an actual delay period based on (i) the timer value and (ii) the predetermined number of times. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
