Localization of a wireless communication device
First Claim
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.

Abstract
A method, computer program product and system for improving the localization of a wireless communication device within an area covered by a transceiver infrastructure includes triggering the wireless communication device to emit a positioning signal. A positioning signal is received from the wireless communication device by a further wireless communication device at a known position within the area covered by the transceiver infrastructure. The transceiver infrastructure includes at least three transceivers. A forwarding positioning signal is transmitted from the further wireless communication device to at least one of the transceivers. The wireless communication device is located based on the forwarding positioning signal.
