Wi-Fi Spectrum Analyzer

AirMagnet Announces Laptop-Based Wi-Fi Spectrum Analyzer
11:27AM 6/15/05  


AirMagnet, Inc., the leader in WLAN security and performance solutions, today announced a new laptop-based RF spectrum analysis solution for Wi-Fi networks. The AirMagnet(R) Spectrum Analyzer -- based on Cognio's patented Intelligent Spectrum Management(TM) System (ISMS) -- is the industry's first to identify the specific sources of interference that can undermine the performance of wireless networks.

The AirMagnet Spectrum Analyzer complements AirMagnet Laptop, the world's most popular Wi-Fi performance and security troubleshooting tool, with its unique ability to proactively identify and find the sources of interference in all of the Wi-Fi bands. With more than 3,500 corporate customers worldwide and more than 200 resellers and distributors in 100 countries, AirMagnet is already the world's leading developer of solutions for Wi-Fi intrusion prevention, security auditing, troubleshooting and site surveys.

"Spectrum analysis can provide our customers valuable information that helps them diagnose network problems, but only if the information is specific and presented in a way that is easy to understand," said Dean Au, president and CEO of AirMagnet. "Cognio's technology adds intelligent analysis that's not possible with proprietary hardware solutions. Used in conjunction with our WLAN Laptop Analyzer, AirMagnet Spectrum Analyzer allows users to ensure maximum network security and uptime for their wireless networks."

The AirMagnet Spectrum Analyzer provides more specific, useful analysis than traditional spectrum analyzers that run on proprietary hardware. Since the AirMagnet product runs on industry-standard laptops, it is also easier to use, more convenient and less expensive than alternatives. AirMagnet Spectrum Analyzer allows network managers to:

-- Perform real-time RF spectrum analysis for troubleshooting WLANs.
-- Detect and identify specific interfering devices in real time, including Bluetooth, cordless phones, microwave ovens and video cameras.
-- Pinpoint the location of problematic wireless devices.
-- Measure RF "air quality," including metrics for radio congestion.
-- Create graphical display of Wi-Fi spectrum in nine simultaneous charts and graphs.
-- Analyze all Wi-Fi and public safety bands of spectrum in use today, including 802.11a, 802.11b and 802.11g.

"The Spectrum Analyzer from Cognio and AirMagnet allows general IT staff to use and benefit from spectrum analysis without requiring an advanced understanding of RF technology," said Tom McPherson, CEO of Cognio. "Users can now quickly and easily determine the specific cause and immediate impact of RF problems."

The AirMagnet Spectrum Analyzer will be available to customers at the end of June. For pricing and additional information, please contact AirMagnet at sales@airmagnet.com.

GPS and Galileo Receiver OEM module

NovAtel Demos First North American Dual Mode GPS & Galileo Receiver
11:35AM 5/31/05  

NovAtel Inc., a precise positioning technology company, announced today that it has successfully demonstrated the performance of a dual mode GPS and Galileo L1/E5A dual frequency prototype receiver to the Canadian Space Agency (CSA), developed under a contract awarded in September 2004. These receivers will be ready to accept signals from the first Galileo satellites scheduled to launch later this year or in early 2006. Galileo is Europe's state-of-the-art satellite navigation system, which is expected to be operational by 2010/12 with up to 30 satellites orbiting the earth.

NovAtel is developing two sets of L1/E5A engineering receivers and L1/E5A transmitters for the CSA for use with Galileo satellites. The receiver is being integrated into a modified version of NovAtel's WAAS-GII system, which also includes the Euro-3M L1/L2 dual frequency GPS receiver. The signal generator is based on a previous design built for the new U.S. Wide Area Augmentation System (WAAS) uplink system.

"This is the first operational, near-production standard, dual mode GPS and Galileo dual frequency receiver in North America," said Tony Murfin, VP Business Development at NovAtel. "We are particularly pleased to have the receiver working this early in the CSA program. We believe the technology we are creating here is unique, and will enable NovAtel to provide GPS/Galileo receiver solutions worldwide and, hopefully, in the ground infrastructure of the Galileo system itself."

Currently, NovAtel supplies GPS navigational receivers to a number of national satellite-based augmentation systems (SBAS) around the world, including the U.S. WAAS, the European EGNOS, Japanese MSAS, Chinese SNAS, and more recently the Gagan system in India. These complex receivers incorporate NovAtel's Narrow Correlator(R) tracking technology, MEDLL multipath reduction technology and Signal Quality Monitoring, and receive and process both WAAS L1/L5 GEO and GPS L1/L2/L5 signals.
