Abstract:
A first device including a timing module and a control module. The timing module is configured to calculate a first delay period between a first time a data frame is transmitted to a second device and a second time an acknowledgement frame is received from the second device. The timing module is further configured to calculate a second delay period between a third time the data frame is transmitted to the second device and a fourth time the acknowledgement frame is received from the second device. The control module is configured to calculate a total delay period corresponding to a sum of the first delay period and the second delay period and determine a distance between the first device and the second device based on the total delay and a number of times for the data frame to be transmitted to the second device.
