Abstract
In a tag communication system, a method includes determining range information representative of a distance between two tags, and estimating parameter information representative of backscatter signals of a marker tag and an asset tag. A tag is localized according to the range information and the parameter information to provide a localized tag. The range information is determined according to a beacon signal. The system includes a plurality of beacon signals and the method further includes determining the range information according to at least two of the beacon signals. A logical operation is performed on the range information of the two beacon signals. A further beacon signal has a plurality of signal ranges and the range information is determined according to the signal ranges. A logical operation is performed on the range information of the signal ranges.
