Cognio this week unveiled Spectrum Expert 3.1, an update of its wireless spectrum analyzer. The new version can advise IT managers on how to respond to interference on their wireless LANs.


Cognio continues to push the envelope of providing expert assistance in spectrum analysis for the average network admin. These latest features are more evolutionary than revolutionary, making this an appropriate minor point release. But it demonstrates that Cognio understands that network admins, sometimes thrust in the role of managing the wireless network, can benefit from a little extra help. Hopefully Cognio's chipsets and software can someday be an integral part of every enterprise-grade access point, facilitating continual and granular RF analysis.

Cognio continues to roll out features that make Spectrum Expert a leader in analyzing and troubleshooting the physical layer of wireless networks. Building on their interference detection engine, Spectrum Expert 3.1 now offers recommendations on how to eliminate or minimize specific sources of interference. Although competitive solutions such as MetaGeek's Wi-Spy and BVS' BumbleBee offer many of the same RFanalysis features as Cognio, they lack interference classification abilities which are crucial to making WLAN spectrum analysis a more intuitive process.

Spectrum Expert 3.1 works by delivering data on the interfering device's spectrum characteristics, the expected effect on network performance and signal strength. To help network managers expedite their response, the analyzer provides a recommended solution to limit or entirely prevent the interfering device's impact on the wireless LAN.

Spectrum Expert 3.1 also includes an instant-replay feature that lets network administrators review live spectrum for diagnostic purposes. And the analyzer offers a "Real-Time Spectrum Snapshot," which displays statistics about interference and spectrum use.

Industry observers say that though this release is largely an incremental upgrade of the Cognio analyzer, it does give IT managers a valuable tool for preserving the performance of their wireless LANs.Analysts note that the increasing complexity of Wi-Fi networks combined with the growing number of devices that can interfere with performance is compounding the challenge of maintaining acceptable wireless LAN performance. Cognio's Spectrum Expert helps IT managers get "closer to total hands-off cognitive Wi-Fi management," said Paul DeBeasi, senior analyst with Burton Group's Network and Telecom Strategies Service.

Spectrum Expert 3.1 is shipping now.
