1. High Density Wireless / BYOD / Distance Learning presentation for October 26th, 2012

2. Introductions Team Members: Mike Martin, Senior Account Executive Jeff Whaley, Business Development Manager-Media Solutions Dave Benham, Wireless Practice Manager

3. 1 st Half (BYOD) Agenda BYOD challenges Importance of an enterprise wireless network High client density challenges Device profiling and posture assessment 802.11n 802.11ac

4. 2 nd Half (Distance Learning) Agenda Toledo Public Schools Overview What problems were being solved? Considerations both technical and administrative. Planning- How was it approached? Technical Design Implementation and Rollout Training, Training, Training

5. BYOD Show of hands: – How many plan to use BYOD for instruction? – How many just have to deal with students/staff bringing devices and expecting internet access? Prepare yourself…

6. BYOD Challenges from a network perspective Security AP Density – Capacity in high density client areas Scalability Management

7. The Importance of an Enterprise WLAN

8. Security User authentication (802.1x) isn’t enough in some environments – PSK isn’t manageable or secure – EAP-TLS can be too complex and time consuming to manage – Machine Auth alone lacks reporting and makes troubleshooting difficult Device profiling is key… Details later in the presentation.

9. Features and Management Spectrum intelligence – Be aware of what you’re really getting – Some solutions require APs to be taken offline to analyze the spectrum – Be proactive not reactive Top talker report Busiest APs report Location tracking Rate limiting Troubleshooting tools Interface groups Load balancing

10. Multicast Video Understand multicast video over WiFi… Multicast must be more efficient than unicast, right? Not necessarily. – Packets sent at highest mandatory data rate – No error correction Solutions: – Implement a wireless solution that efficiently manages multicast video – Use unicast video

11. High Client Density Challenges

12. Clients using more bandwidth than you think? WiFi is a shared medium – Bandwidth surge at beginning of class period GPOs Deep Freeze – Print drivers – AV and application updates Roaming profiles All of the above = long delays at the beginning of class time

13. Bad clients Aluminum cases – WiFi doesn’t like it – Guess what most popular mobile devices are made of? Weaker signal = slower data rate More clients with slow data rates means less bandwidth available for all clients Solutions: – More dense AP deployment – Beamforming

14. Device Profiling and Posture Assessment

15. Device Profiling – 1 st defense Allows different access levels to be automatically applied to different devices, even when using the same credentials. – For example: Mobile devices = Internet + AirPlay Laptops allowed full access with posture assessment – No need for certificates, etc. – Can isolate or deny access to certain device types as well

16. Posture assessment – 2 nd defense Performs additional checks to verify the workstation is yours before allowing full network access – Can validate just about anything on the device before allowing network access

17. 802.11n – More than just speed Reliability – Making use of multipath to increase SNR Capacity – Faster processors in the APs allow more clients connect to a single AP And of course, speed – 450mbps with 3x3 @ 5GHz – 144mbps (20MHz channels) @ 2.4GHz

18. 802.11ac – To wait or not to wait? 802.11ac = Gigabit wireless 5GHz only – Similar propagation to existing 802.11n (5GHz) 80MHz channels = less available channels. 3, to start. More transmitters may have negative impact on battery life Best bet: Use upgradable APs in high capacity areas, and 802.11n APs everywhere else, for now.

20. Classrooms of the Future-Distance Learning Case Study Presentation for October 26th, 2012

21. Agenda Toledo Public Schools Overview What problems were being solved? Considerations both technical and administrative. Planning- How was it approached? Technical Design Implementation and Rollout Training, Training, Training

22. Toledo Public Schools Toledo Public Schools Case Study Overview

23. Large K-12 located in Northwest Ohio Faced with reduced Funding and Student Count Needs to increase Educational Offerings to its students Facing Geographical Challenges

24. What Problems were being Solved?

25. Problems to be solved In the face of reduced student counts and funding, trying to find a way to provide advanced course content amongst its 7 High Schools. Being tasked with building advanced learning environments-(ie. Virtual classrooms) Changing Educational times….Kids are learning differently Geographic Limitations for providing classes to all seven High Schools Funding forcing hard decisions around available course content.

26. Considerations both Technical and Administrative

27. Considerations Technical- – Network…Am I ready? – Scheduling….what is necessary to make this work – End User interface……simple is best! – Room Layout and Design…….best user experience Administrative- – Big Changes for educators……they must be on board – New way to teach…teaching for the future – Be selective with classes…..decide what works best – Planning, Planning, Planning

28. Planning- How was it approached?

29. Successful Planning Have all affected parties involved- Develop a planning team with everyone represented (IT, Facilities, Senior Leadership, Educators, etc.) Room Selection Course Selection Targeted Educators- They must be excited and onboard! District Communications (bell schedule, course scheduling etc.) Network Considerations- Bandwidth and QOS This takes time…Not a solution to enter in to quickly.

30. Technical Design

31. Room Selection – Physical room location – Security Choose the Right Equipment for the best user experience – Projectors/Displays/Smart boards – Control Systems – Sound Reinforcement – Video Conferencing Codec Room Layout – Camera Angles – Correct Seating layouts for number of students – Lighting – Acoustics Network – Switch Infrastructure – Back Haul

32. Implementation and Rollout

33. Timing and Scheduling Network complete and tested ahead of time. Leave Time for Testing Prepare for Training

34. Training, Training, Training

35. Training Training for Educator Training for Room Facilitator (Para) Training For IT Support Training For System Administrators Training Tools- Factor into design
