Cisco this week said it will purchase privately held Cognio, a maker of spectrum analysis and management systems for wireless networks.

Terms of the acquisition were not disclosed.

Cognio, based in Germantown, Md., develops products to detect and mitigate sources of radio frequency (RF) interference in corporate wireless networks. Reduced interference translates to better performance for mobile applications, Cisco says.
The Cognio acquisition is expected to close in the first quarter of Cisco's 2008 fiscal year, which began last month. At that time, Cisco plans to integrate Cognio into its Wireless Networking Business Unit, under the Ethernet and Wireless Technology Group.

The Cognio acquisition will be No. 122 for Cisco and the first one in fiscal year 2008.

Wireless is part of Cisco’s Advanced Technology group, which also includes application networking services, home networking, security, storage networking and unified communications.
