Abstract: A method is described for locating an electronic device in the vicinity of an array having a central unit and anchors connected to the central unit. The method is applied during at least a communication cycle comprising a plurality of time slots each allocated to a distinct anchor. The method involves receiving an initiation signal from the electronic device, performing an election of a set of anchor(s) based on the reception quality of the initiation signal, emitting a reply signal during a respective allocated time slot, operating the electronic device in a first configuration during the time slots which are not allocated to one of the anchors the elected set, operating the electronic device in a second configuration during the time slot allocated to the elected set to detect and receive a reply signal, and calculating a location of the electronic device based on the reply signal.
