Wireless interference has been identified as one of the top causes of wireless performance issues. The new product has clear air technology as its USP. It combines a patented CleanAir Application-Specific Integrated Circuit (ASIC) in the access point with system-level intelligence to detect, classify, locate and mitigate the impact of wireless interference.

This new spectrum intelligence technology tackles challenges of radio-frequency interference, making mission-critical wireless networks more reliable. It is a significant development as more and more employees are going mobile and more and more wireless networks are acquiring mission-critical importance.

How it works?

ClearAir Technology can reduce wireless troubleshooting time from hours to minutes and, in many cases, can automatically resolve problems. It can assess the problem and adjust the wireless signal to operate in an unaffected spectrum in just about 30 seconds.

It accurately locates interference sources visually represented on a floor plan making it easy for IT infrastructure managers to identify and remove interference sources quickly. It intelligently detects and classifies more than 20 unique interference sources including cordless phones, wireless video cameras, microwave ovens and Bluetooth devices while simultaneously serving client traffic.

Other highlights include:

    * An intuitive Air Quality Index for a comprehensive assessment of the severity of interference affecting any given access point or specific location.

    * Interference co-relation across multiple access points to prevent duplicate events from the same interference source.

Cisco Aironet 3500 Series is scheduled to be available from May 2010. The latest release of Cisco Unified Wireless Network 7.0 integrates clean air capabilities across Cisco’s Wireless Control System, the 3300 Series Mobility Service Engine and all Cisco Wireless Controllers.
