摘要： A method of direction finding (DF) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas simultaneously, which allows a receiving device to resolve multiple DF sounding signals transmitted from the multiple antennas. As a result, angle of departure (AoD) of the transmitting device can be estimated by using the multiple resolved DF sounding signals from each antenna for DF positioning purpose.

摘要： The present invention relates generally to wireless transceivers, and more particularly but not exclusively to non 802.11 detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting non 802.11 operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as AP, are provided. An AP is used to automatically detect the presence of non 802.11 on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of non 802.11 using one or more implementations.
