SEATTLE, WA--(Marketwire - August 11, 2009) - Leading UHF Gen 2 radio frequency identification (RFID) technology provider Impinj, Inc. today announced the availability of the Speedway® Revolution reader, which incorporates the company's innovative Autopilot technology to deliver new standards in RFID reader performance, ease of use, versatility, reliability and cost of ownership.

Critical to Speedway Revolution's outstanding performance and ease of use, Impinj's patented Autopilot technology continuously and automatically optimizes the reader for its operating environment to deliver peak performance at all times. Because RFID system performance depends upon a multitude of ever-changing environmental conditions (including RF interference levels, tag density in the reader field and ambient RF noise) users configure readers for worst-case scenarios, compromising optimum performance in the process. Autopilot guarantees peak performance while eliminating the need for manual tuning by integrating several innovative features, including:

--  Autoset, which continuously optimizes the reader's configuration for
    the best, most reliable performance. Speedway Revolution readers sense
    levels of RF noise and interference, automatically selecting the
    appropriate settings.
--  Low duty cycle, which reduces RF interference, power consumption, and
    energy costs. Speedway Revolution readers only transmit when tags are in
    the field of view, eliminating unnecessary RF noise.
--  Dynamic antenna switching, which improves throughput and efficiency.
    Speedway Revolution readers sense where tags are in the field and
    automatically focus more time on antennas with the largest tag populations
    in view. For example, if a low-height pallet follows taller pallets through
    a portal, a Speedway Revolution reader will reduce wasteful time spent on
    antennas in the upper positions.

Speedway Revolution builds on the industry-leading reputation of the original Speedway reader and delivers the superior performance and versatility required to address even the industry's most difficult applications. In addition, with features like Power-over-Ethernet (PoE) and support for the standard application interface, EPCglobal Low-Level Reader Protocol (LLRP), Speedway Revolution provides low cost of ownership and easily integrates with leading RFID middleware platforms.

"End-users need RFID systems to deliver great performance in dynamic environments, and they want readers to be easy to deploy and inexpensive to own," said Kerry Krause, vice president of marketing at Impinj. "Speedway Revolution represents a quantum leap in reader design, inspired by our experience as the worldwide leader in UHF RFID tag chips, reader chips and fixed readers. The combination of Autopilot along with Revolution's small size and extremely low power consumption delivers consistently superior performance, unparalleled ease of use and significant cost savings for end-users."

Speedway Revolution is available now in both a four-port configuration at an MSRP of $1,585 and a two-port configuration at $1,385. Measuring only 6.75" x 5.5" x 1" (17 cm X 14 cm X 2.5 cm), Speedway Revolution is 80% smaller than the original Speedway reader, consumes less than half the power and has a 20% lower MSRP, making it hassle-free, easy to install and inexpensive to maintain and operate.
