    • 2. To Start: A Thought to Remember
      “The Internet has no core, just an ever-expanding edge…”
      Wireless LANs are just the latest in a long line of edge technologies enhancing the user experience

      Tactical Deployment
      “Get it off my network!”
      “If you are having problems, plug in”
      Controllers were designed to tame this beast

    • 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
