MetaGeek Updates Software for its Wireless Spectrum Analyzer

By Calvin Azuri March 20, 2008
MetaGeek launched the newest version of its wireless spectrum virtualization software, Chanalyzer 3.0. This software comes packaged with the company’s Wi-Spy v2.4x USB wireless spectrum analyzer. These two components work together to help users visualize, troubleshoot and optimize Wi-Fi networks.
Chanalyzer’s power lies in its ability to identify signatures of specific electronic devices that may be causing a disruption in any 2.4 GHz wireless network signal. This enables improved installation of wireless devices and faster troubleshooting.
The software also fills the requirement for a low-cost efficient analyzer that can be used by anyone, without the price being prohibitive. This is important because the number of devices that now operate in the 2.4 GHz frequency have multiplied.
MetaGeek claims that its Wi-Spy analyzer is the smallest device of its kind. It can plug into any USB port to collect information about the wireless network, using the power of the computer it is plugged into. The Chanalyzer software then converts the data and presents it visually. The toolset can be used to discover devices that may be disrupting the network.
The software has three views to assist with troubleshooting. Tthe Spectral View highlights bandwidth use over time using a waterfall graph. The Topographic View generates a map that shows the popularity of the system over time.  Finally, the Planar View provides in-depth analysis of signals’ strengths and channel usage.
Another fundamental difference between the Wi-Spy with Chanalyzer solution and similar products is that it’s designed to be used for troubleshooting rather than dictating usage patterns.
Some of the newer additions to the software are signature identification, a data inspector, time controls, recording cropping facility, sharing of recordings, embedded notes recording playback and a resizing of views option.
Chanalyzer 3.0 runs on Microsoft Windows 2000, XP, or Vista with .NET 2.0 installed. Linux and Mac compatibility are also available via third-party software.
Wi-Spy 2.4x can scan the radio frequency range from 2.400 GHz to 2.4835 GHz (and 2.495 GHz for channels 12-14 in Europe and Japan), with a resolution of 328 KHz. It can detect signals in the amplitude range of -110 dBm to -6.5 dBm, with a resolution of 0.5 dBm, and has a sweep time of 165 milliseconds.
