WIDE-AREA DYNAMIC RFID SYSTEM USING UWB

摘要

A wide area radio frequency identification (RFID) system includes: a first RFID cell and a second RFID cell. The first RFID cell and the second RFID cell each include a reader and tags. The readers access the tags using ultra-wide band signaling. The RFID cells each include: a communications interface operable to communicate with a network operations center, and a communications gateway which supports direct communications between RFID cells. The method includes accessing the second RFID cell from the first RFID cell, and the accessing is performed using the communications gateway that can cover a range of at least five hundred meters.

主权项

1. A wide area radio frequency identification (RFID) system comprising:
at least two RFID cells, wherein a first RFID cells includes a first reader and a first plurality of tags and a second RFID cell includes a second reader and a second plurality of tags, wherein the first reader is configured to accesses the first plurality of tags and the second reader is configured to access the second plurality of tags; wherein the first RFID cell and the second RFID cell include
a communications gateway operable to support direct communications between at least the first RFID cell and the second RFID cell;wherein, via the communications gateways of the first RFID cell and the second RFID cell, the first reader of the first RFID cell is configured to query data from, or write data to, a tag within the second plurality of tags of the second RFID cell;wherein the second RFID cell is configured to receive a security alarm from the first RFID cell via the direct communications that is arranged over a range of at least five hundred meters.
