Patent ID: 7728786

Claim:
A Radio Frequency Identification system (RFID) to capture a remote microwave frequency or ultra high frequency interrogation of RFID transponders attached to articles in a warehouse or distribution center environment through a microwave or ultra high frequency RFID inquiry emanating from a cellular phone transmission tower wherein said system comprises: A directional external yagi antenna affixed to the exterior of the distribution center or warehouse distribution center; and said external yagi antenna further being channel cut to correspond precisely to a remote electromagnetic signal direction and frequency; an electric motor attached to a boom of the external yagi antenna to enable the antenna to change direction; a directional finding equipment spliced to the circuit of the external yagi antenna so that the pointing direction of the antenna is shifted to the cellular telephone transmission tower of a cellular telephone transmission cell division which is currently handling data transmission in relationship to the antenna; multiple transformers, the antenna and interrogation units mounted to a ceiling of the warehouse or distribution center to modulate and reradiate signals of the remote microwave or ultra high frequency interrogation to interrogate transponders attached to articles at the articles' resonant frequency and re-radiate responses to the external yagi antenna for capture by the cellular transmission tower; said multiple transformers, antenna and interrogator units being powered by wall sockets and connected electronically to the external yagi antenna; the transponders attached to the articles stored within the interior environment of the warehouse or distribution center.
