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
WLAN Trends in Higher 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
WLAN Trends in K-12 Education

Planning First Year
Expected significant increasein usage
Existing APs upgraded to 802.11n
Planning First Year
Increased coverage by re-purposing older APs
Increased number of APsfrom 120 to 160
The First Year
Added 1300 devices
MacBook, iPhone, iPod touch
35% load increase
1000 simultaneous at peak
Planning Year Two
Existing APs upgraded to 802.11n
Increased coverage by re-purposing older APs
Now up to 190 APs
The Second Year
Added another 1600 devices
Added iPad & iPhone 4
Traffic peaking at 55 Mbps
Peaked at 1400+ connections
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
Future Plans
Upgrade Residence Halls to 802.11n
100 Mb internet connection in RHs
100 Mb internet connection for main campus

Expectations
• Communicate with your customer• Understand how will your infrastructure be
used• Develop a multi-year plan• Implement improvements before they are
needed
Applications
• Keep track of new technology• Know how your infrastructure will be affected• Baseline your wireless network• Be proactive
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
