TESSCO Offers Next Generation in Wi-Fi Spectrum Analysis

IT Managers Maximize Network Performance With Cognio's Laptop-Based Spectrum Expert(TM)

HUNT VALLEY, Md., June 20 / -- TESSCO Technologies Incorporated (NASDAQ:TESS), a value-added supplier of the product solutions needed to design, build, run, maintain and use wireless systems, today announced the introduction and availability of Cognio's award-winning Spectrum Expert(TM) wireless spectrum management tool. Spectrum Expert improves TESSCO's ability to provide unique analysis capabilities in solving and troubleshooting Wi-Fi interference issues during deployment.

TESSCO and Cognio both recognize that as enterprises replace wired networks with Wi-Fi networks for their primary LAN infrastructure, they concurrently incorporate applications such as wireless VoIP - to improve the productivity and efficiency of mobile employees. In today's business environment, Voice over Wi-Fi applications often fail to perform to their potential due to shared bandwidth or interference associated with devices such as Bluetooth headsets, cellular phones, PDAs, video cameras, microwaves and other 802.11 equipment.

Cognio's Spectrum Expert provides IT managers the tools they need to maximize Wi-Fi network performance, while minimizing the impact of interference by moving, removing, shielding, or replacing specific, interference-causing devices. The Spectrum Expert delivers a solution for operating a wireless spectrum securely, and at peak performance levels - via this "next generation" wireless spectrum analysis tool that runs on an industry-standard laptop, subsequently boosting ease-of-use, convenience and cost-effectiveness.

"This is an exciting new addition to our spectrum analysis product offering - Cognio gives our customers a cost-effective and easy-to-use, PC- based spectrum management tool, while enhancing TESSCO's total source offering of the product solutions that make wireless work," said Mary Beth Smith, vice president of TESSCO's Installation, Test and Maintenance Solutions line of business.

"TESSCO is ideal for Cognio as we aggressively move to expand our channel strategy to reach deeper into the enterprise market," said Greg Barone, vice president of sales for Cognio. "By including the industry's only full- featured, compact Wi-Fi network analysis tool, TESSCO will be able to leverage both current and new customer demands for optimized network performance."

The Spectrum Expert(TM) provides:
-- View of 802.11 RF spectrum and FFT duty cycle for better troubleshooting of Wi-Fi networks
-- Location of the source of interference with Cognio's patent-pending "device finder"
-- Measurement of RF "Air Quality," including metrics for radio congestion
