Original Abstract Submitted
The invention proposes a transmitter (such as a gateway or base station, both indoors and outdoors) that actively creates multiple virtual anchors which are associated with certain known reflectors by means of a code, to allow low-capability receivers to be localized more easily. By measuring propagation features, such as, e.g., timing of receipt, of three or more coded beams, low capability receiversâeven those with only a single antennaâcan be localized, e.g., by the transmitter or by the receivers themselves. The receivers might localize themselves if each beam includes e.g. the location of the anchors, the location of transmitter, and the sending time. This has the advantage that the receivers do not have to send any information back to the transmitter.
