At a distance of 7 meters, home appliances like microwaves can interfere with wireless crowded spectrums. Cisco’s new product “Cisco CleanAir” improves air quality by detecting radio frequency interference that other systems are not able to. Its sensors also detect the source of these interferences on a floor plan. Cisco CleanAir is one of the next generation wireless technology products reviewed by Fikread Kidane, Cisco System engineer East Africa during the recent Cisco Expo held in Nairobi.

Cisco CleanAir enables wireless networks to heal and optimize themselves automatically from an impact of network interference. Because of the radio frequency spectrum involves a lot of variables that frequently change, there is need to have visibility into the spectrum and prevent unexpected downtime to businesses. Cisco CleanAir becomes handy especially for latency sensitive applications like video and voice being used in business enterprises. It is also able to keep a log of interference information for back in time analysis.

The product allows unified networks on a Cisco platform to correlates sources of interference across the network, allowing organizations make intelligent decisions and policies for faster troubleshooting and automatically avoid RF interferences. Network administrators will have an easy time using CleanAir to assess service disruption in their networks, they are able to receive notices about performance degradation and quickly take action.

Wireless communication has since moved from basic email (11mbps) to ubiquitous mobile computing (300mbps). Cisco's new Aironet 1140 Wi-Fi access point, a second product reviewed during the expo adds the ability to send directional signals so existing Wi-Fi clients can share in the speed improvements provided by 802.11n. This is because of the change of using wireless capacities.
In mixed environments, clients using older devices with 802.11a/g delay communications for 802.11n clients and reduce system performance. Recognizing the need for businesses to protect their investment in these 802.11a/g devices, Cisco has developed a new technology that allows businesses to deliver the performance benefits of 802.11n to 802.11a/g devices, thereby increasing their useful life.
