Method and apparatus for tracking via a radio frequency identification device
First Claim
1. A method, comprising:
- receiving, by a system including signal processing circuitry, a first wireless signal of a first carrier frequency from a radio frequency identification device, wherein the first wireless signal includes first information;
generating, by the system, a transmission signal of second carrier frequency, wherein the transmission signal includes the first information; and
generating, by the system, at a first physical interface of a transmission medium, electromagnetic waves that convey the transmission signal, wherein the electromagnetic waves are guided and propagate along the transmission medium without requiring an electrical return path, and wherein the electromagnetic waves are received by a receiving device at a second physical interface of the transmission medium.

Abstract
Aspects of the subject disclosure may include, for example, a device, including a radio frequency interface configured to receive, from a radio frequency identification device, a first wireless signal of a first carrier frequency that indicates a personal identifier. A transceiver can be configured to generate a transmission signal of second carrier frequency that indicates the personal identifier and location information associated with the device and to transmit electromagnetic waves in response to the transmission signal at a first physical interface of a transmission medium that propagate without requiring an electrical return path. The electromagnetic waves are guided by the transmission medium and are received by a receiving device at a second physical interface of the transmission medium, and the transmission signal can be extracted from the electromagnetic waves by the receiving device. Other embodiments are disclosed.
