Abstract: A system comprising: a transmitting device configured to transmit, in at least one plane, a plurality of directional signals each covering an angular sector, wherein every adjacent pair of said angular sectors overlaps partially to create a logical sector, and wherein each of said plurality of directional signals encodes at least an indication regarding each said logical sector associated therewith; and a client device comprising program instructions executable by at least one hardware processor to: cause the client device to receive at least some of said plurality of directional signals, calculate a signal strength level (RSL) value for each of said received directional signals, and determine that said client device is located within a said logical sector, when two highest said RSL values (i) are related to two said directional signals associated with said logical sector, and (ii) are within a specified value range of each other.
