Abstract
A first wireless device (e.g., an access point) receives a message from a second wireless device (e.g., a client device). The first device determines an angle-of-arrival of the message at a plurality of antennas of the first wireless device. The first device compares the angle-of-arrival with an angle-of-arrival threshold to determine whether to transmit a response message to the second wireless device. In one example, the first wireless device is a wireless access point device operating in a wireless network, the second wireless device is a wireless client device operating in the wireless network, the message is a probe request message and the response message is a probe response message.
