Abstract:
A method for communicating between elements including a reader and tags of a radio frequency identification system. The method includes addressing a wide-band-message signal by including in the signal an identifier of the first tag. The addressed wide-band-message signal is transmitted by the reader. A first tag waits to receive the addressed wide-band-message signal; and upon receiving the addressed wide-band-message signal and recognizing the identifier, the first tag responds to the addressed wide-band-message signal by transmitting an addressed wide-band response signal either back to the reader or to a relaying tag. The tag relays to another element of the system by transferring at least one datum of the query from the addressed wide-band-message signal to the addressed wide-band response signal, where the elements are readers or tags. The system and method allow for many parallel wide band addressed links, and for position determination using at least two tags with known locations.
