NEWS!-- SIRIT Inc. Announces RFID Reader Patent Filings --
News Editors
TORONTO--(BUSINESS WIRE)--Nov. 23, 2004--SIRIT Inc. (TSX:SI), a
leading provider of radio frequency identification (RFID) hardware
technology, today announced that it has filed three new patent
applications related to RFID reader technology with the U.S. Patent
and Trademark Office.
SIRIT specializes in RFID reader and tag design, development and
manufacturing. Its RFID readers incorporate low, high and ultra-high
frequency products, which are the required spectrums in its principal
markets. In addition to the design and manufacturing of RFID
readers, SIRIT has significant understanding of the inner workings of
RFID tags, including EPC tags that are becoming the standard in
worldwide supply chain applications. This experience, resident within
SIRIT's engineering team, is particularly important to creating RFID
reader designs that push the edges of performance.
Many of the engineering challenges in RFID technology reside
within the domain of the radio portion of an RFID reader. SIRIT's
patent filings revolve around unique and innovative implementations
of RFID radio concepts. Throughout its eleven year history SIRIT has
developed a reputation for excellence in the field of RFID radio
design.
SIRIT's three patent filings deal with this RFID radio section.
An RFID radio differs from traditional radio design in the fact that
both the radio transmitter (the "tag illuminator") as well as the
radio receiver (which deals with the weak tag response signal) are
active at the same time and virtually at the same frequency. This
requires a very clean transmit signal in combination with a high
receiver blocking point while maintaining receiver sensitivity,
requirements that typically are difficult to combine.
Loek d'Hont, Chief Technology Officer, SIRIT Inc. stated, "These
patent applications reflect unique innovations that SIRIT believes
are essential to ensure that RFID readers can meet the performance
standards demanded by its customers in the supply chain market. For
the end-user, these innovations will result in greater reader
sensitivity and consistency while maintaining abundant illumination
power to the tag. Such increased sensitivity is imperative for an
effective RFID system, since it will improve system performance in
those cases where "real-life" situations are a challenge, such as
obstructing objects in the RFID read zone or RF absorption from items
on pallets in a supply chain application."
"In addition," Mr. d'Hont continued, "the patent filings are
targeted at achieving more robust read performance for RFID objects
that are in high-speed motion, as well as developing a more effective
way of dealing with RF multi-path situations. All of this is
important for RFID performance in supply chain applications."
The three patent applications specifically relate to a) the above
mentioned performance improvements, b) a more intelligent method of
receiver baseband processing, and c) allowing for aggressive design
to cost objectives in RFID reader design while maintaining maximum
read range performance, which is very important for RFID applications
that are highly cost-sensitive, such as RFID printers or RFID mobile
computers.
