Wireless is becoming the primary access method of choice, so:
• Infrastructure High Availability and Resiliency is now required
• 802.11r Fast Secure Roaming is standardized
• Client SSO (stateful switchover) is desirable
• Management and visibility for 99.999% uptime
• New requirements by vertical:
– Transportation Retail Healthcare
– Manufacturing Oil&Gas Mining

• Most efficient Wi-Fi standard to date
• Optimized for power savings
• Optimized for high density
• Multi-user mode – “Switch-like”(Wave 2)
• Wired-like speeds and experience –consistent connectivity at higher speed
• Significantly better client battery life
• Significantly better Access Point device handling capacity
Practical Considerations for 802.11ac
• 802.11ac will be deployed in 5.0GHz only.
• Most implementations will be 3 Streams for the first few years.
• Nominal real throughput will consistently be in the range of ~300 to 400Mbps
• Client device adoption will be rapid to take advantage of extended battery life
