Vision: 4G/LTE and eduroam both asaccess network for campus Campus Challenge: usersneed to experience SURFnetseamless roamingbetween Wi-Fi and LTE Internet 16 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-qualityratio17 18. 4G+eduroamBuilding blocks schematic overview AAA AAA proxy AAA SURFnetUser home eduroam DB instituteVisiting institute InternetAAA proxyAAA SURFnetUser generic DBhome MobileinstituteoperatorInternet AAA proxy AAA home institutional instituteSURFnetUserDB MobileoperatorInternet 18 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.

In Practice: Pilot 4G eduroam for Education & Research21 22. Utrecht Science Park Coverage (20 m2)9 km (5.6 mi) Pilot Area6 km (3.7 mi) Antenna location 22 23. Huge Media attention23SURFnet - We make innovation work 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. Many questions to address What is the added value of a fully 4G coverage on the campusfor educational purposes? How does it stimulate the new working and learning? Whichapplications can be used now, that couldnt be used before?Does it enable better cooperation among students andteachers? What new educational developments does it start? Is the 4G service comparable with the eduroam (Wi-Fi) serviceand can we provide seamless roaming? How should the eduroam/3/4G infrastructures best beintegrated? 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. 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. 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 28.

Conclusions There is a role for NRENs in 4G to enable learning andresearching everywhere Operators seem interested in the educational market and alsoWi-Fi offloading techniques. Opportunity to cooperate 4G/LTE as complementary access network for campusesseems like a good way to go 4G can be great add-on for non-WiFi locations (and viceversa), but roaming has to be as seamless as possible Gathering demand for a specific 4G eduroam service canassure a transparent, safe accessible wireless internet for ourusers Cooperate within GEANT for pan-european mobile service 31 32.
