5 The trends driving education and Wi-Fi Device BYOD Proliferation There will be over 3 Billion Wi-Fi devices by Gartner 1:1 School Deployments Parental Contribution Schemes Technology has a vital role to play in closing the attainment gap. Multi-media internet and educator created resources Billions of Wi-Fi Devices Worldwide Collaboration & communication tools E-learning foundation Students expect to be able to work, learn, and study whenever and wherever they want to. Horizon Report > 2012 Cloud Services Cloud Services Wi-Fi has become mission critical infrastructure in education"

7 The Wi-Fi Goals. Every Where, For Every One, For Everything, From any device. Mobility 7

8 Why BYOD relies on the 2.4Ghz spectrum 5GHz devices <25% of 6800 at UoS

9 BYOD Challenges USER REQUIREMENT Simple, quick connection Simple infrequent authentication Access to appropriate resources Security and Privacy OPERATIONAL ISSUES Users must be uniquely identifiable Credentials must be created and distributed Credentials must be revoke-able Users must be classified Access must be differentiated Guest networks are not encrypted There is no control over devices We don t have the resource to configure or troubleshoot BYOD devices

10 Connectivity Challenges On boarding Self Help We ll Get to You

11 802.1X IS THE ANSWER, BUT 802.1x is hard to configure on clients 1. Connect to a network 2. Select your protocol 4. Trust the server certificate (lets hope its installed already) 5. Choose how you send your username 3. Select the EAP type

12 SMARTCONNECT ONE CLICK CONFIGURATION Access Point 1. Authenticate using web authentication 2. One Click to configure 802.1x 3. Automatically connect with 802.1x Supported Platforms Windows ipad/iphone Apple Mac Android

13 Customer Expectations

14 Customer Expectations Not Being Met Insecure or Manual onboarding Dropped sessions Reduced network performance Sticky Clients Domestic devices don t roam More access points do not improve performance No! Site surveys Reactive management IT scale requires human scale Destroyed by density, mobility, density interference,.

15 Application Challenge On Campus Mobility -dbm [-65dBm Throughput for (Mbps) Smart phones] Single Channel vs. Microcell Call Drops Location Microcell Virtualized

16 Density vs. Capacity Capacity of Campus 7,000 simultaneous users 30,000 unique Wi-Fi devices Capacity of Hall 250 students 1000 devices 500 # Clients

17 Connectivity challenges - Very High Density How come I ve got signal, but can t run this video? Lecture Hall Chaos Reduced Learning Distracted Students Unfair Access

18 Key Takeaways - BYOD BYOD Wi-Fi > 50% of LAN traffic by 2015 Client control Root cause of connectivity, mobility, application issues Wi-Fi WLAN architecture matters There is another choice: IT can regain control

19 Introducing ac Phase Ghz only 2. Backwards compatibility 3. 80Mhz wide channels 4. Higher modulation rates 256QAM Phase 2 1. MU-MIMO Mhz wide channels Mhz wide 4. Increased Spatial streams Uptake??
