Abstract

A method comprising: wirelessly receiving, at a first device, at least one data packet from each second device of a plurality of second devices arranged at predetermined locations of a target; detecting an angle of arrival of each at least one data packet wirelessly received of at least a pair of second devices; calculating at least one angle difference between the angles of arrival associated with the pair of second devices, or between the angles of arrival associated with each of the pair of second devices and a predetermined direction; and determining whether the target is at a predetermined distance range from the first device by estimating the distance based on the at least one angle difference, and a predetermined distance between the predetermined locations; or checking whether each of the at least one angle difference is within a predetermined angle range for the predetermined locations of the pair of second devices. Also, a method for making such determination based on angles of departure.
