Cisco CleanAir technology uses silicon-level intelligence to create a spectrum-aware, self-healing, and self-optimizing wireless network that mitigates the impact of wireless interference and offers performance protection for 802.11n networks.
The value of Cisco CleanAir technology
Cisco CleanAir technology delivers the performance of 802.11n and the reliability required to support mission-critical applications, all while intelligently avoiding the impacts of interference.
Self-healing and self-optimizing wireless
With Cisco CleanAir technology, if an interference source is strong enough to completely jam a Wi-Fi channel, the system will change channels within 30 seconds to avoid the interference, resuming client activity on another channel outside of the affected area. The system remembers intermittent interference from persistent sources such as a microwave ovens, wireless bridges, or wireless video cameras.
Effective policy enforcement
With CleanAir technology, network administrators have the ability to track network performance, locate and see the impact of non-Wi-Fi devices, and enforce policies by verbosely identifying the source device, location, and time and date. This "what, where, and when" information gives administrators the tools they need to prevent network outages, educate users on the issues and policy, and monitor for compliance.
Custom chipset implementation
Only Cisco has invested in creating a custom chipset optimized to allow detection of non-Wi-Fi wireless transmissions while simultaneously serving network traffic. Because the detection and classification takes place on inline silicon and because it has access to rich, low-level data not available with standard Wi-Fi chipsets, Cisco CleanAir technology produces interference visualizations that are much more detailed and precise than those produced by competing systems.
High-definition interference visualization
Cisco CleanAir technology is uniquely broad in its ability to detect 20 different interferers, and uniquely granular in its ability to visualize interference impact. These capabilities support more intelligent decisions and policies, for automatic remedial action and faster troubleshooting.
Rather than managing interference on one access point at a time, Cisco CleanAir technology aggregates the impact of interference across the entire network. It can provide both real-time and historical views of interference across the whole system and down to a single client.
