MiCOM Labs Adds Dynamic Frequency Selection Testing And Certification Capability

Pleasanton, CA -- MiCOM Labs, Inc. announced that it has added the capability to test wireless products using dynamic frequency selection (DFS) to its list of accredited wireless services. Growing use of the 802.11 wireless (Wi-Fi) technology has intensified the need for DFS, which is a technology that enables unlicensed devices to share spectrum with existing radar systems. DFS is currently used in the 5.25 to 5.35 GHz and 5.47 to 5.725 GHz frequency bands.

"DFS standards are set in Europe and in Japan and will soon be available in the U.S.," said MiCOM Labs CEO Gordon Hurst. "MiCOM Labs has already completed DFS testing for one client to the latest draft European standard, and we anticipate that requirements for DFS testing will grow as standards are adopted in more regions of the world. We are pleased to expand our services and increase the value we can bring to our clients with the addition of DFS testing."

In the scheme of DFS frequency sharing, "master" devices monitor for potential radar interference and provide channel selection instructions to "slave" devices. If interference is detected during monitoring, the master device signals to other devices to move to a new channel. DFS standards set the time requirements for interference monitoring, detection, and channel move time; thresholds of signal detection; and similar performance parameters. ETSI standard EN 301 893 in the European Union was among the earliest standards to recognize DFS.
