Rfid: a Broad Overview

RFID: A Broad Overview Network and Telecommunications Concepts I/360 Ms. Marjorie Marque December 5, 2005 RFID: A Broad Overview Introduction Radio Frequency Identification is part of the loquacious category of automatic identification technologies. Auto-ID technologies include bar codes, ocular character readers and others, such as retinal s advises. So what is RFID and what can this technology be used for? Radio Frequency acknowledgment (RFID) is a system consisting of a tag, a reader and whatever particular form of electronic data processing equipment, such as a computer (see Tag below). The system is evenhandedly simple to operate. Unlike bar codes, which must be tight to the scanner for reading, encoded signals from the tag and the reader are wirelessly transmitted by dint of radio waves across greater distances. RFID not only has the prefer of longer read distances, it also has the ability to read with dirt, rain, snow, fog, direct sunlight and non-metallic objects. RFID can be used to give away, sweep and sort a wide variety of objects. RFID Tag History This technology has tardily had an impact on so many companies that the majority of hatful would presume the RFID proposals are new.

Conversely, research indicates that RFID technology appears to have had its rat roots in World War II. According to the RFID Journal, Germans find the radio signals were changed as they were reflected back to the base after peppy off planes rolling in the air. This method would alert the radiolocation crew on the ground that the plane was friend or foe and, as such, was the first passive RFID system (2005). In 1932, the British invented the IFF transponder under Watson-Watt. It was the first active system to identify friend of foe (IFF). The paper, entitled Communication by inwardness of Reflected Power (Proceedings of the IRE, pp1196-1204, October 1948) by Harry Stockman, is seen as a watershed in the development of RFID technology and has lead to much...
