High Density Wireless / BYOD / Distance Learning presentation for October 26th, 2012 Introductions Team Members: • Mike Martin, Senior Account Executive • Jeff Whaley, Business Development Manager-Media Solutions • Dave Benham, Wireless Practice Manager st 1 Half (BYOD) Agenda • BYOD challenges • Importance of an enterprise wireless network • High client density challenges • Device profiling and posture assessment • 802.11n • 802.11ac 2nd 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 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… BYOD Challenges from a network perspective • Security • AP Density – Capacity in high density client areas • Scalability • Management The Importance of an Enterprise WLAN 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. 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 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 High Client Density Challenges 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 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 Device Profiling and Posture Assessment Device Profiling – st 1 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 Posture assessment – 2nd 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 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 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.

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. Considerations both Technical and Administrative 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 Planning- How was it approached? 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. Technical Design Technical Design • 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 Implementation and Rollout Implementation and Rollout • Timing and Scheduling • Network complete and tested ahead of time. • Leave Time for Testing • Prepare for Training Training, Training, Training Training • • • • • Training for Educator Training for Room Facilitator (Para) Training For IT Support Training For System Administrators Training Tools- Factor into design Q&A Thank You! Control System A Solid Business Partner Why do Customers do Business with Netech? • • • • • • We understand the public sector!
