摘要:
A method and apparatus for remote UWB powering of passive RFID tags, sensors, and other electronic devices at long ranges and still at FCC low emission power limits utilizes a distributed multi-transmitter system configured for spotforming. The UWB powering signal is different from the signal that is used for communication between the tag and its reader. By de-coupling the powering task from the communication task, one is able to increase the range of communication between the tag and the reader, as readers can be designed to have excellent receiver sensitivities, while powering range is increased by use of multiple “spot-forming” antennas over a large area.
