Angle of arrival of personal area network devices using a switched beam antenna

A switched beam antenna (SBA) implemented in a first wireless device, for determining an angle of arrival (AOA) corresponding to communication between the first wireless device and a second wireless device, the SBA comprising:

• processing circuitry configured to determine a first beam having a first width and a sector of beam coverage from which the first wireless device pages the second wireless device and a paging sequence is received, the sector of beam coverage of the first beam encompassing a plurality of second beams pointing in different directions, each second beam being narrower than the first beam;
• a radio interface in communication with the processing circuitry and configured to:
• transmit in succession, on each of the second beams during a respective time duration, an identifiable sequence of first traffic packets;
• and
• for each second beam transmission, receive a plurality of second traffic packets from the second wireless device in response to the identifiable sequence of the first traffic packets during the respective time duration;
• and
• the processing circuitry being further configured to:
• for each second beam transmission:
• record a signal strength for each second traffic packet in the plurality of second traffic packets;
• and
• determine an average signal strength for the plurality of second traffic packets during the respective time duration;
• and
• determine an AOA by selecting a second beam from the plurality of second beams that results in a highest average signal strength of the determined average signal strengths.
