1. A wireless access point comprising:
- at least one transmitter associated with a corresponding antenna; and
a processor coupled to the transmitter, wherein the processor causes frames to be transmitted by the at least one transmitter so that the frames are received by at least one client device with a receive signal strength so as to cause the at least one client device to determine a determined distance between the at least one client device and the wireless access point, such that a frequency of transmission of probe request messages transmitted by the at least one client device is increased or decreased based on the determined distance, wherein;
if the receive signal strength increases, the at least one client device determines that the determined distance is smaller than the at least one client device would have determined if the receive signal strength had not increased, thereby causing the at least one client device to decrease the frequency of transmission of probe request messages; and
if the receive signal strength decreases, the at least one client device determines that the determined distance is greater than the at least one client device would have determined if the receive signal strength had not decreased, thereby causing the at least one client device to increase the frequency of transmission of probe request messages.

Abstract
In one embodiment, a wireless access point that serves at least one client device in a wireless local area network transmits frames to the at least one client device so that the frames are received by the at least one client device with a receive signal strength so as to control the transmission of probe request messages by the at least one client device.

-
at a wireless access point that serves at least one client device in a wireless local area network, transmitting frames to the at least one client device so that the frames are received by the at least one client device with a receive signal strength so as to cause the at least one client device to determine that a determined distance between the at least one client device and the wireless access point such that a frequency of transmission of probe request messages transmitted by the at least one client device is increased or decreased based on the determined distance, wherein; if the receive signal strength increases, the at least one client device determines that the determined distance is smaller than the at least one client device would have determined if the receive signal strength had not increased, thereby causing the at least one client device to decrease the frequency of transmission of probe request messages; and if the receive signal strength decreases, the at least one client device determines that the determined distance is greater than the at least one client device would have determined if the receive signal strength had not decreased, thereby causing the at least one client device to increase the frequency of transmission of probe request messages. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
