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:

receiving a data transmission transmitted using UWB;

accessing data within the data transmission using a communications protocol wherein 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.

2. The method of claim 1 wherein the initial portion is a decoding template.

3. The method of claim 1 wherein the data transmission is associated with an RFID tag.

4. An RFID tag, comprising:

a 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 defines a structure of the data transmission such that subsequent data in the data transmission is directly accessible without additional decoding.

5. A method for communications, comprising structuring a time modulated UWB telecommunication packet to include a first tag indicating a start position of the pulse and a second tag indicating a broadcast frequency of the pulse.

6. The method of claim 5 further comprising sending the time modulated UWB telecommunication packet.

7. The method of claim 5 further comprising receiving the time modulated UWB telecommunication packet and using the first tag and the second tag to assist in accessing information within the packet.
