World wide explosion of mobile dataSource: Cisco VNI mobile 2012

• Global mobile data traffic grew 2.3-fold in 2011, more than doubled for the 4th 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

Mobile data in the Netherlands

• 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 MBmobile traffic per personper day (32TB/day in total)

Data hungry devices

Basic phone 4.3 MB/month

Smart phone 150 MB/month

Laptop 2.1 GB/month

= 35x

= 1x

= 120x= 488x

Tablet 517 MB/month

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

Page 9: Wireless ambitions

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

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?• …..

SURFnet’s LTE building blocks

1. Institutional traffic- Transparent tunnel from KPN to the institution

2. Generic traffic- SURFnet routes traffic to destination, on behalf of institution

Two network building blocks

Institutional traffic Generic 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

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
