  2. 2. Disclaimer: The views and opinions expressed in this presentation are those of the author / presenter and do not necessarily reflect the official position of the CCSR or 5GIC.
  3. 3. Introduction to 5GIC 3 5GIC: 5G Innovation Center  A successful funding bid made by the University of Surrey to the UK Research Partnership Investment Fund (UKRPIF)  Supported by additional contributions from a consortium of enthusiastic and forwarding-thinking operators, infrastructure and solution providers (Founding Members)  Will provide research and business engagement opportunities for multinational companies and SME  The 5GIC is the world's first dedicated 5G programme and an international hub for telecommunication research and innovation with a unique large scale 5G test-bed for network testing.
  4. 4. Ubiquitous, high quality and affordable communications (essential to the functioning of modern life & society) Around half of over 3 B devices connected to internet today are via wireless networks Increasingly the internet is being formed as network of ‘things’, rather than network of computers Hyper-connectivity of billions of devices nut just P2P but P2D, D2D, M2M makes the Internet-of-Things an ever growing phenomenon Users are adopting new habits, how they use mobile phones and how they access the internet More powerful and enabled devices are becoming available and affordable Services are also growing in multiplicity, diversity and richness of content End user delight is absolutely essential to the success of telecom industry Broadband the 4th Utility + Mobile Broadband Outlook Transport Commerce Education Health UtilityICT Telecommunication at the heart of several industries, Transport, Utility, Education, Health & Commerce 4

  11. 11.  3G: Started in 1989, standards in 1999, commercial system in 2003  4G: Started in 2000, standards in 2008, commercial in 2011  5G: Already started, standards in 2017+, commercial readiness in 2020 Cellular standards quick to arrive and slow to leave ~ 10 years between major new standards Average of 20 years from STD to peak deployment 2G in 1990’s, 3G in 2000’s, 4G in 2010’s AND 5G in 2020’s 5G Time Lines 11
  12. 12. Capacity the biggest driver for 5G will not be delivered via one technique but a combination of several techniques  Much denser network and small cells will be a key part of 5G design  NW will need to be designed with future services/application in mind BUT not for particular services Spectrum remains to be the greatest challenge for telecom industry Sharing is a must in 5G – spectrum sharing to be enabled both in terms of technology and also business model  Sharing is good for 5G - greater degree of sharing, site, infrastructure, … (new operation and business models) The shape of NW architecture will need to change – mobile to play a role as NW node (D2D,mesh NW, …) Telecom industry needs to cope with exponential growth phenomenon!  5G success depends not only on the underlying technologies but also in rethinking business models, policies and economics around radio spectrum regulation 12 Concluding Remarks
