5G: A Technology Vision 5G wireless networks will support 1,000-fold gains in capacity, connections for at least 100 billion devices, and a 10 Gb/s individual user experience capable of extremely low latency and response times. Deployment of these networks will emerge between 2020 and 2030. 5G radio access will be built upon both new radio access technologies (RAT) and evolved existing wireless technologies (LTE, HSPA, GSM and WiFi). Breakthroughs in wireless network innovation will also drive economic and societal growth in entirely new ways. 5G will realize networks capable of providing zero-distance connectivity between people and connected machines.

Next Wave of Digital Society The advent of 5G technologies and ICT networks signify the coming next wave of a globally connected Digital Society: Right now, all over the world, mobile access to the internet is becoming • wholly fundamental to doing business in all industries. Flexible working practices facilitated by mobile networks and devices are already essential, and are allowing enterprises to conduct operations across boundaries that previously inhibited growth. Growing mobile access to the internet, cloud-based services and Big Data • analytics is allowing anyone, anywhere to leverage “Big Wisdom” – a whole new kind of globally connected and shared knowledge base. The continuing rise in the relevance of social media as an important • part of how we interact with the internet is also opening up new kinds of intelligent analytics ready to be harnessed for tangible business and everyday life benefits. Transformation and convergence of ICT network infrastructure is driving • business innovation and growth. Not only is ICT an increasingly effective tool for enhancing efficiency, but it is now a vital driver of economic and societal growth. The development of 5G technologies is a cornerstone for realizing breakthroughs in the transformation of ICT network infrastructure. Ultra- broadband and intelligent-pipe network features that achieve near- instantaneous, “zero distance” connectivity between people and connected machines – no matter where they are – are just the first step. A changing telecoms landscape The current generation of mobile networks continues to transform the way people communicate and access information. Further developing and implementing technologies that enable true human-centric and connected machine-centric networks will come to redefine end user mobility along with the entire landscape of the global telecoms industry. 5G will herald an even greater rise in the prominence of mobile access for 2 realizing total ICT network growth and expansion. Over time, any mobile app and any mobile service will be given the potential to connect to anything at anytime – from people and communities to physical things, processes, content, working knowledge, timely pertinent information and goods of all sorts in entirely flexible, reliable and secure ways. This is the promise of 5G: to expand the possibilities of what mobile networks can do, and to extend upon what services they can deliver. Internet evolution 5G will drive the future evolution of the internet itself. What we mean when we refer to the “internet” is likely to change: Implementing the next generation of ubiquitous ultra-broadband network • infrastructure will require a rethinking, restructuring and redesigning of approaches to mobile network construction and expansion. Integration of mass-scale cloud architectures will infuse mobile networks • with capabilities for flexibly delivering services at unprecedented speeds while meeting forecasts for tremendous growth in mobile data traffic, diversification of mobile app innovation, IoT connectivity, and security. To achieve these goals, developments in 5G will primarily focus on two fundamental aspects for eliminating infrastructure bottlenecks: massive capacity and massive connectivity. Immediacy and adaptability Massive capacity for delivery of services will allow connections between end users and the network to be made at “faster than thought” speeds – so fast that the apparent distance between connected people and connected machines will shrink to a virtual “zero distance” gap. An instant immediacy in mobile services will lay the foundation for a whole new set of mobile apps to proliferate and push the capabilities of communications beyond what is currently possible. A more massive capacity for managing connections will better enable a greater widespread adoption of M2M services and interactions, and will facilitate innovation in localized mobile service delivery. The next wave of the Digital Society will be characterized by an ICT network’s capability for service immediacy and on-demand ad。
