802.11n: Mission-Critical Wireless

Create a transparent working environment across wired and wireless networks with the performance and reliability required for rich-media and business-critical applications.

802.11n wireless combines the mobility of wireless with the performance of wired networks, offering up to 9 times the performance of 802.11 a/g networks. Providing true enterprise-class RF, Cisco technologies such as CleanAir, ClientLink, and VideoStream, plus optimized access point radio and antennas, improve performance regardless of where a device is located.

CleanAir Technology

CleanAir technology uses silicon-level intelligence to create a self- healing, self-optimizing wireless network that mitigates the effects of wireless interference. With an application-specific integrated circuit (ASIC) based implementation of spectrum management, CleanAir can classify over 20 different types of interferers within 5 to 30 seconds.

It also improves air quality by:

• Detecting RF interference that other systems can't see
• Identifying the source and locating it on a floor plan
• Providing automatic adjustments to optimize wireless coverage around the interference

VideoStream

VideoStream provides clear, accurate video images everywhere by efficiently delivering multicast video from the wired to the wireless network.

VideoStream technology:

• Maintains video quality at a perfect 5.0 medium opinion score (MOS) score
• Delivers three times the scalability of competing products
• Optimizes network performance by using 30 times less bandwidth than competing products

ClientLink

ClientLink allows access points to bridge gaps in coverage, increase access, and provide a signal in challenging environments. It also works with all existing 802.11a/g clients.

ClientLink technology:

• Increase throughput for lower-speed 802.11n a/g clients
• Improve coverage areas between cells or near obstacles
• Ensure airtime "fairness" so that all clients, regardless of location or version of the 802.11 standard, have the optimal connection to the Cisco wireless network
