Abstract

A method associated with a UWB RFID system provides for receiving a data transmission transmitted using UWB and accessing data within the data transmission using a communications protocol. An initial portion of the data transmission defines a structure of the data transmission such that subsequent data in the data transmission is directly accessible without additional decoding.

Claims

1. A method for communications, comprising:

providing an RFID tag, the RFID tag comprising a processor and a UWB radio operatively connected to the processor and an interface port operatively connected to the processor;

receiving a data transmission transmitted using UWB from the RFID tag;

accessing data within the data transmission using a communications protocol wherein an initial portion of the data transmission comprises a tag identifier followed by a partition to identify a decoding template and defines a structure of the data transmission such that once decoded subsequent data in the data transmission is directly accessible without additional decoding.

2. An RFID tag, comprising:

a processor;

an interface port operatively connected to the processor;

a UWB radio operatively connected to the processor;

wherein the processor is adapted to send data using a communications protocol wherein an initial portion of a data transmission comprises a tag identifier followed by a partition to identify a decoded template and defines a structure of the data transmission such that once decoded subsequent data in the data transmission is directly accessible without additional decoding.

3. An RFID tag, comprising:

a processor;

an interface port operatively connected to the processor;

a UWB radio operatively connected to the processor;

wherein the processor is adapted to send data in a structured linear database communications protocol which includes an initial portion of the data transmission comprising a tag identifier followed by a partition to identify a decoding template and which defines a structure of the data transmission such that once decoded subsequent data in the data transmission is directly accessible to a receiver without additional decoding of a subsequent portion of the data transmission containing the subsequent data.
