Abstract
A method and apparatus for measuring confidence in the angle of arrival AOA of Wi-Fi packets, from a target station, using a switched beam antenna SBA is described. AOAs can be inaccurate due to reflections and multipaths. To assess the confidence of an AOA, each AOA is first converted to relative north, AOAt, and checked that at least M AOAs have been received in time T. If so, the standard deviation is calculated for of all the AOAs received during previous time T. If the standard deviation is less than a preset value, and the receiving station is not stationary, then the AOAt is considered to have high confidence and may be used to calculate the target station location. A vector display of the AOA uses the standard deviation to display the AOA vector as a varying length or a varying beamwidth corresponding to the standard deviation.
