802.11n Makes Rightsizing Possible802.11n Makes Rightsizing Possible
• Higher Throughput (~150 Mbps throughput)
• “…for many enterprises, 802.11n throughput will be good enough”*
• Reduced Latency• “…More than good enough for most latency-sensitive
applications.”*
• Better Performance for Voice Applications• “…Good enough for most jitter-sensitive applications”*
• Widespread adoption• 50% of chipsets in 2008 will be 802.11n; 90% by 2013**
• 802.11n is backward-compatible to support 802.11abg devices

Enterprises Can Start Rightsizing Today
• More than 11,000 Aruba access points
• 80,000+ unique clients connecting to the network
• 70% said the wireless network saved them at least 5 work hours a week because of increased flexibility
• 72% of employees said they can work without any wires
“Because of large user adoption of wireless connectivity it is not difficult to envision a time when we transition to an all-wireless workplace.”
Victoria Poncini, Microsoft’s Network Architect
