Mobile Learning & Your Wireless Network Tom Anderson Apple Network Engineer Shenandoah University
iMLearning Integrated Mobile Educational Experience
Planning First Year Expected significant increase in usage Existing APs upgraded to n
Planning First Year Increased coverage by re-purposing older APs Increased number of APs from 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 n 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 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 n 100 Mb internet connection in RHs 100 Mb internet connection for main campus Cloudpath XpressConnect
Dempsey Peterson Abilene Christian University Network Administrator - Wireless
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
