Abstract:
Various embodiments transmit targeted beacon frames using beamforming techniques. Using a first beam-formed wireless connection to a user device, a wireless networking device dynamically learns directional and/or spatial location information associated with the user device, such as transmission and/or reception angles. In turn, the wireless networking device stores the directional information in a location database to track successful connections to user devices. Some embodiments target the transmission of beacon frames to a predefined coverage area by using the stored directional information to determine transmission parameters for a second beam-formed wireless signal. Alternately or additionally, some embodiments use pre-programmed values to determine the transmission parameters of the second beam-formed wireless signal. Responsive to determining the transmission parameters, the wireless networking device transmits beacon frames via the second beam-formed wireless signal to transmit the beacon frames to the predefined coverage area.
