Abstract
Heatmap data, such as Angle-of-Arrival heatmap data, is generated and stored for a plurality of antennas of wireless communication device. A centroid of the plurality of antennas is determined. A heatmap is computed for the centroid for a measured parameter across a plurality of bins at coordinates within a region of interest. Heatmap data for the centroid is stored. For a given one of the plurality of antennas, a difference is computed between a heatmap for the given antenna and the heatmap for the centroid. The difference data representing the difference is stored for the given antenna.
