The capital cost and productivity advantages of Wi-Fi over cabling every cube, and the substantial performance
improvements of 802.11n over previous generations of Wi-Fi, make 802.11n WLANs the primary user network
connection in tomorrow’s enterprise. Learn why this is the case and the implications for your network.

    “Get it off my network!”
    “If you are having problems, plug in”
    Controllers were designed to tame this beast
    Networking’s Redheaded Step Child!

  • 15. Even More Speed:Looking ahead to 802.11ac & 802.11ad
    After “High” throughput (11n) comes “Very High”
    Two task groups formed
    11ac: Gigabit at < 6 GHz (large backwards compatibility concerns with 802.11a/b/g/n)
    11ad: Gigabit at 60 GHz (no backwards compatibility, but very short range)
    Improvements on existing technologies
    Coding: 256-QAM instead of 64-QAM
    Channel width: Adds 80 & 160 MHz channels
    Multiuser-MIMO (MU-MIMO)
    Simultaneous beamforming to multiple receivers
    Like Ethernet switching – reduces contention for medium access
    Strong driver of distributed forwarding

  • 17. Implications of Wireless 2.0
    Pervasive Deployment
    Wi-Fi is becoming the primary access layer
    Wi-Fi can save money, but to maximize the benefits, the Wi-Fi implementation must itself be:
    Cost-effective, Scalable, Ease to Manage
    Multiservice Infrastructure
    Wi-Fi is now expected to be capable of supporting any application, device, or user type…yet…
    Wi-Fi is a shared medium with instantaneous variations in SNR
    Security / Authentication
    Strong Authentication Integration, Segmentation, WIPS
    Secure Flexible Guest Networking
    Risk Mitigation
    Availability, Performance, Redundancy
