Abstract:
1. A method for improving the localization of a wireless communication device within an area covered by a transceiver infrastructure that is controlled by a control unit, the method comprising: triggering the wireless communication device to emit a positioning signal; selecting a further wireless communication device from multiple wireless communication devices that receive positioning signals from other wireless communication devices and that report a list of other wireless communication devices from which a positioning signal has been received to at least one transceiver, the selecting based on their respective lists of other wireless communication devices; activating the further wireless communication device; receiving the positioning signal from the wireless communication device, the receiving by the further wireless communication device at a known position within the area covered by the transceiver infrastructure, the transceiver infrastructure comprising at least three transceivers that are connected to the control unit; transmitting a forwarding positioning signal from the further wireless communication device to at least one of the transceivers; and determining, by the control unit, a location of the wireless communication device responsive to the forwarding positioning signal.
