First Claim
1. A radio frequency identification (RFID) carrier comprises:
- a receive module coupled to recover signaling information from an RFID signal to produce recovered signaling information;
oscillation module coupled to generate at least one oscillation based on the recovered signaling information;
a transmit module coupled to convert the recovered signaling information into a repeat RFID signal based on an oscillation of the at least one oscillation; and
a power source module coupled to provide at least one supply voltage to at least one of the receive module, the oscillation module, and the transmit module.

Abstract
An RFID carrier includes a receive module, an oscillation module, a transmit module, and a power source module. The receive module is coupled to recover signaling information from an RFID signal to produce recovered signaling information. The oscillation module is coupled to generate at least one oscillation based on the recovered signaling information. The transmit module is coupled to convert the recovered signaling information into a repeat RFID signal based on an oscillation of the at least one oscillation. The power source module is coupled to provide at least one supply voltage to at least one of the receive module, the oscillation module, and the transmit module.
