IMT-2000,, IMT-Advanced, & IMT-2020 All of today’s 3G and 4G mobile broadband systems are based on the ITU’s IMT standards. IMT provides the global platform on which to build the next generations of mobile broadband connectivity. ITU established the detailed specifications for IMT-2000 and the first 3G deployments commenced around the year 2000. In January 2012, ITU defined the next big leap forward with 4G wireless cellular technology – IMT-Advanced – and this is now being progressively deployed worldwide. The detailed investigation of the key elements of IMT-2020 is already well underway, once again using the highly successful partnership ITU-R has with the mobile broadband industry and the wide range of stakeholders in the 5G community. 5G Usage scenarios 2

Key areas of network study: Architecture enabling convergence Fixed access networks to interwork with radio access networks Goals for IMT‐2020: A converged access‐agnostic core ‐ identity, mobility, security, etc., are decoupled from the access technology Network architecture to support fixed / mobile convergence, with seamless user experience Architecture discussion at a Focus Group meeting, Palo Alto, September 2016 Photo by Marc Mosko, PARC 5G, open source and IPR ITU collaborates with open source initiatives to develop proofs of concept addressing technical issues identified Workshop & Demo Days at ITU: 7 December 2016, 11 July 2017 2nd ITU‐NGMN workshop on "Open Source and Standards for 5G" (Bellevue, WA, USA, 1 November 2017) Conclusions of 1st workshop: ‐ Open source needed in the context of 5G ‐ Open source components will complement the development of standards in 5G ‐ Open source and standards are converging and both can benefit in 5G from each other ‐ Open source and standards are not two different worlds, and close cooperation creates opportunities for both 9

Coverage versus speed trade‐off reflects a larger debate about social objectives versus ‘cherry‐picking’ profitable areas. Need a credible, viable commercial business case going forward for 5G deployments to happen in most optimal way. 11

Broadband Wireless Access for connecting the unconnected ITU-BDT is responsible for projects on implementing broadband wireless networks. Aiming at addressing the issues of developing countries, Resolution 2 (Rev. Dubai 2014) of the WTDC established within the Study Group 1 the Question 2/1Broadband access technologies. In this context, capacity building activities and guidelines on IMT and related wireless and wireline technologies to Membership are being developed to assist the spread of broadband access and the achievement of the SDGs, especially Summary The scope of IMT‐2020 is much broader than previous generations of mobile broadband communication systems. Use cases foreseen include enhancement of the traditional mobile broadband scenarios as well as ultra‐reliable and low latency communications and massive machine‐type communications. The ITU's work in developing the specifications for IMT‐2020, in close collaboration with the whole gamut of 5G stakeholders, is now well underway, along with the associated spectrum management and spectrum identification aspects. IMT‐2020 will be a cornerstone for all of the activities related to attaining the goals in the 2030 Agenda for Sustainable Development. 12
