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

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

A method and apparatus for measuring the angle of arrival AOA of Classic Bluetooth Basic Rate (BR) packets, using a switched beam antenna SBA is described. Paging packets are transmitted and wide antenna beams, quadrants, are selected in turn until the paging response is received. After transmitting...

description A method and apparatus for measuring the angle of arrival AOA of Classic Bluetooth Basic Rate (BR) packets, using a switched beam antenna SBA is described. Paging packets are transmitted and wide antenna beams, quadrants, are selected in turn until the paging response is received. After transmitting the synchronization packet and the temporary connection is established, narrow antenna beams are selected, in sequences and the average signal strength for each beam is recorded, for each sequence. The beam with the highest signal strength is returned as the AOA. Based upon which beam recorded the highest signal strength, the next sequence of antenna beams is selected.
