Summary: | A system that exploits collaboration between a plurality of spatially distributed RFID readers to enhance the range of commercial passive RFID tags, without alteration to the tags. The system uses distributed MIMO to coherently combine signals across geographically separated RFID readers. It is capable of inferring the optimal beamforming parameters to beam energy to a tag without any initial knowledge of the location or orientation of the tags. |
