Abstract
Methods are disclosed that improve the location of a ground based Wi-Fi device using an airborne Wi-Fi station. One embodiments of the disclosure describes the periodic transmission of bursts of RTS packets in order to reduce interference to the responding CTS packets. Another embodiment of the disclosure describes the use of specific values used in the RTS Duration fields that enable the responding CTS packet to be identified and linked to the RTS packet to which it is responding. A further embodiment of the disclosure describes the use of a packet transmitted at the end of each burst that resets the NAV times for all ground networks.
