<p>The present invention is related to a method for determining a location of a target device in connection with one or more beacons having a known position in a space. The method comprises the steps of :
- transmitting with a transmitter device a plurality of signals having a different transmit signal power, said transmitter device being the target device or a beacon of said one or more beacons,
- receiving at least two of the plurality of transmitted signals with a receiver device, said receiver device being the target device or a beacon of said one or more beacons and being different from the transmitter device, and determining for the at least two received signals an indication of the received signal power,
- estimating the location of the target device via information on the distance between the transmitter device and the receiver device derived from a weighted sum of the indications of the received signal power of the at least two received signals, whereby the weights of the weighted sum take into account the different transmit signal powers.</p> |
