  16. 16. Vision: 4G/LTE and eduroam both asaccess network for campus Campus  Challenge: users need to experience SURFnet seamless roaming between Wi-Fi and LTE Internet 16
  17. 17. 4G and eduroam seamless integratedaccess network: the advantagesAllow students, researchers and employees to collaborate,research, learn anytime and anywhere they seem fit!• Transparent wireless internet access via NREN• Carefree, Trusted and Safe connectivity• Technology Agnostic campus (WiFi/4G/3G…)• Possible integration with campus services (e.g. UC)• Good basis for cloud and federative services• Opportunity to gather demand for optimum LTE price-quality ratio 17

  19. 19. LTE+eduroam: building blocksTwo building blocks:1. Institutional traffic - Transparent tunnel from LTE to Layer2-infra at the institute2. Generic traffic - LTE direct connected to the internet, via the SURFnet-backbone19
  20. 20. Features building blocks compared Feature Institutional Generic Default traffic traffic Telco LTE LTE can be regarded similarly as Yes No No local Wi-Fi traffic Secure access based on eduroam Yes Yes No credentials Internet access though SURFnet Yes Yes No IP address from institute Yes Yes No Native integration with unified Yes No No communication (voice, e-mail,…), local printing etc Allows monitoring of traffic, Yes Possible Partly authentication Allows strong demand Yes Yes Partly aggregation20
  21. 21. In Practice: Pilot 4G eduroam for Education & Research21

  23. 23. Huge Media attention23 SURFnet - We make innovation work
  24. 24. Goals of 4G eduroam pilot1. Build and share knowledge, determine added value of 2.6 Ghz LTE networks in education and research environments2. Develop technical architecture and test environment for integration of LTE and eduroam3. Encourage development of mobile apps for education and research, using LTE/eduroam/federative concepts4. Get input for tendering a combined eduroam and 4G/3G service for customers B2C and B2B with the following features: - Provider 4/3G coverage (inter)national - Use of eduroam credentials for network-access - Offloading to eduroam Wi-Fi on “hotspots” and campuses - Use capacity of SURFnet backbone - Potential of one million users - Integrated with campus services (e.g. Library service, UC) 24
  25. 25. Many questions to address… • What is the added value of a fully 4G coverage on the campus for educational purposes? • How does it stimulate the new working and learning? Which applications can be used now, that couldn’t be used before? Does it enable better cooperation among students and teachers? What new educational developments does it start? • Is the 4G service comparable with the eduroam (Wi-Fi) service and can we provide “seamless roaming”? • How should the eduroam/3/4G infrastructures best be integrated? • What are the characteristics of IPv6 on 4G • Can we use the smart card for access to federated service? • Does it save costs, improve quality or both? 25
  26. 26. 4G trials at the institutes• Veterinary Medicine @ University of Utrecht - Assessment during clinical operations in the field (mobile access to ePASS) - Remote supervision during clinical operations - Consulting literature, study material• Journalism @ Hogeschool Utrecht - Camera and location for education course• UMCU - Integration in Distributed Antenna system (Wi-Fi / LTE roaming) and user experience - Streaming video to monitor alarms in Intensive Care - Web lectures via 4G26 SURFnet - We make innovation work
  27. 27. Status of our 4G eduroam pilot• LTE Service up and running (since May 11th, 2012)• LG Optimus LTE Smartphone devices expected this week + Dongles• Research questions for the first pilot worked out• 4G eduroam architecture in progress (next slides)Q3: - 4G trial inside SURFnet offices - Architecture 4G eduroam implemented - Start trial with Utrecht Medical Hospital.Q4: - Start trial with Hogeschool Utrecht2013: Involve another campus, test roaming2012: New developments: New operator, new campus!27

  31. 31. Conclusions • There is a role for NRENs in 4G to enable learning and researching everywhere • Operators seem interested in the educational market and also Wi-Fi offloading techniques. Opportunity to cooperate • 4G/LTE as complementary access network for campuses seems like a good way to go • 4G can be great add-on for non-WiFi locations (and vice versa), but roaming has to be as seamless as possible • Gathering demand for a specific ‘4G eduroam’ service can assure a transparent, safe accessible wireless internet for our users • Cooperate within GEANT for pan-european mobile service 31
