4. WLAN Trends in Higher Education Migration to .11n Still supporting a/b/g, but .11n is taking off as an overlay New dormitory construction with fewer Ethernet ports in rooms • Opting for pervasive WLAN coverage WLAN expansion into instructional areas • Move from public and outdoor green spaces to academic areas Dense AP coverage • Proliferation of mobile devices • Behavior of mobile devices vs. computers

5. WLAN Trends in K-12 Education Move to structured architecture • Away from COWs with standalone AP/Router. • Need to support 2014 National Core Curriculum Assessment Testing 1:1 Computing expansion • Districts opting for providing laptops or mobile devices Host Integrity Checking • Districts allowing student owned devices to access the network • Need to confirm alignment with security policies and AV posture Voice over WLAN • In lieu of Mobile phones – cost containment • Still usable outside for lunch/recess or bus duty

9. Planning First Year Expected significant increase in usage Existing APs upgraded to 802.11n

10. Planning First Year Increased coverage by re-purposing older APs Increased number of APs from 120 to 160

11. The First Year Added 1300 devices MacBook, iPhone, iPod touch 35% load increase 1000 simultaneous at peak

12. Planning Year Two Existing APs upgraded to 802.11n Increased coverage by re-purposing older APs Now up to 190 APs

13. The Second Year Added another 1600 devices Added iPad & iPhone 4 Traffic peaking at 55 Mbps Peaked at 1400+ connections

14. What Did We Learn? More wireless devices = more demand Especially in Residence Halls Make sure you have sufficient internet connection More time managing the wireless environment

15. Future Plans Upgrade Residence Halls to 802.11n 100 Mb internet connection in RHs 100 Mb internet connection for main campus CloudpathXpressConnect

20. Expectations • Communicate with your customer • Understand how will your infrastructure be used • Develop a multi-year plan • Implement improvements before they are needed

22. Applications • Keep track of new technology • Know how your infrastructure will be affected • Baseline your wireless network • Be proactive

24. Device Density • “Steer” devices to the 5.8 MHz “a” band • Don’t “over install” access points • Don’t be afraid to reduce AP transmit power • Understand the limitations of your network
