Embodiment Construction

[0023]This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

[0024]FIG. 1 illustrates a communication system 10 embodying the invention. Communication system 10 comprises an electronic identification system in the embodiment described herein. Communication system 10 may be configured for backscatter communications as described in detail below. Other communication protocols are utilized in other embodiments.

[0025]The depicted communication system 10 includes a plurality of remote communication devices 12 and an interrogator 26. Wireless (e.g., radio frequency) communications can occur intermediate remote communication devices 12 and interrogator 26 for use in identification systems and product monitoring systems as exemplary applications.

[0026]Remote communication devices 12 can include radio frequency identification devices (RFID) or remote intelli...

Abstract

The present invention relates to wireless communication systems, interrogators and methods of communicating within a wireless communication system. One aspect of the present invention provides a wireless communication system including at least one remote communication device configured to communicate a return link wireless signal; an interrogator including: a communication station configured to receive the return link wireless signal and to generate a return link communication signal corresponding to the return link wireless signal; communication circuitry coupled with the communication station and configured to communicate the return link communication signal; and a housing remotely located with respect to the communication station and including circuitry configured to receive the return link communication signal from the communication circuitry and to process the return link communication signal.

Description

TECHNICAL FIELD[0001]The present invention relates to wireless communication systems, interrogators and methods of communicating within a wireless communication system.BACKGROUND OF THE INVENTION [0002]Electronic identification systems typically comprise two devices which are configured to communicate with one another. Preferred configurations of the electronic identification systems are operable to provide such communications via a wireless medium.[0003]One such configuration is described in U.S. patent application Ser. No. 08 / 705,043, filed Aug. 29, 1996, assigned to the assignee of the present application, and incorporated herein by reference. This application discloses the use of a radio frequency (RF) communication system including communication devices. The disclosed communication devices include an interrogator and a remote transponder, such as a tag or card. Another example of a wireless communication system including a backscatter system is described in U.S. Pat. No. 5,649,...
