1. Wireless ambitions Frans Panken I2 Spring meeting 24 april 2012

2. World wide explosion of mobile data Source: Cisco VNI mobile 2012 2 Global mobile data traffic grew 2.3-fold in 2011, more than doubled for the 4 th year in a row. In 2011 mobile data traffic = 8x size of the entire global Internet in 2000 In 2011 mobile network connection speeds grew 66 percent In 2011, 4G connections ~ 0.2% but responsible for 6% of mobile traffic Smartphones = 12% of global handsets (in NL: > 50%) but responsible for 82% global handset traffic

3. Mobile data in the Netherlands 3 16,5 million inhabitants; 22 million mobile subscribers Currently: 3 mobile operators: KPN, Vodafone, T-mobile LTE frequencies May 2010: 2,6 Ghz, 5 companies Dutch regulator favors competition: privileges for new mobile operators New frequency auctions in October 2012: 800Mhz, 1800 Mhz, 2100 Mhz, 2600 Mhz The Dutch send ~ 4.5 MB mobile traffic per person per day (32TB/day in total)

4. Data hungry devices Basic phone 4.3 MB/month Smart phone 150 MB/month Laptop 2.1 GB/month = 35x = 1x = 120x = 488x Tablet517 MB/month Source: Cisco VNI mobile 2012

5. SURFnet’s public mobile ambitions Towards mobile privileges for people @ higher education and research institutes Towards a solution applicable to several mobile operators Towards a solution that can be applied to all education and research centers Complementary to Wi-Fi connectivity Start with data only. Voice may follow … High-level approach: make use of existing assets -Network for off-loading mobile traffic -Authentication infrastructure for identifying members of the community

6. Radio challenges 6 R&E radio requirements

8. 4G eduroam Pilot 8

9. Status of our 4G pilot Aim at covering the complete value chain: mobile operator- SURFnet – use cases at institutions Agreement with KPN signed (October 2011) LTE antenna’s & equipment placed at Utrecht science park (December 2011) LTE network operational: end of April 2012 Agreement with LG for delivery of 4G-enabled devices: start with 30 LTE-optimus devices Various use cases at various institutions 9

10. 10 Utrecht Science Park Coverage Antenna location 6 km (3.7 mi) 9 km (5.6 mi) Pilot Area

11. Many questions addressed in the 4G pilot 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? ….. 11

23. Two network building blocks Institutional trafficGeneric traffic LTE can be regarded similarly as local Wi-Fi traffic Web access through mobile devices Allows integration with unified communication (voice, e-mail,…) No unnecessary traffic to institution Allows monitoring of service level agreements Suitable for mass contracts Fits well within the SURFnet 7 approach Mainly internet access 23

24. Next steps…. Design document, reflecting technical solution Implement both solutions & evaluate trough trials with institutes Towards a validated technical blue print Towards a sustained business case: who’s paying whom? Incorporating other operators Expanding with another campus 24
