Solid progress in 5G achieved
5G is easily the #1 industry conversation starter at the moment despite the fact that the commercial launch of 5G networks is still 5 years ahead of us. Even though the industry hasn’t even entered the standardization phase yet, the selection and development process for key technology enablers has already started.
At Mobile World Congress 2015, 5G was the media darling and well represented, with Nokia also showcasing a broad lineup of 5G-related demos covering a variety of 5G aspects and participating in various 5G discussions. Some might argue that 5G is an over-inflated topic that will soon fall from the top of the hype curve to the valley of disappointment. To some extent, this might be the case – but solid progress can be reported in important areas:
Applications: What 5G will be good for and what technical requirements that imposes on the network have become much clearer. The industry has widely adopted Nokia’s view that 5G will be about people and things as per the following three use case categories:
1. Massive broadband that delivers gigabytes of bandwidth on demand
2. Critical machine-type communication that allows for the immediate, synchronous eye-hand feedback that enables remote control over robots
3. Massive machine-type communication that connects billions of sensors and machines
Innovation partnerships: Ultimately, the creation of a successful 5G standard requires the best ideas to be adopted, no matter where they come from. And requirements from outside the telecom industry are very important to consider. For example, Nokia has established a broad range of innovation partnerships to find a common direction through collaboration in requirement setting, technology research and finally in standardization – and the forums to achieve this are definitely in place. Work on 5G is now also officially in the 3GPP plan and work has already begun on channel models for frequencies above 6 GHz. This will offer the possibility for very high data rates as more spectrum is expected to become available following the World Radio Conference-19 and subsequent WRCs.
Technology enablers: We are already well on the road with proofs of concepts for many of the technological advances that we consider to be a crucial part of the upcoming 5G standard. Nokia Networks has already prototyped future 5G radio design, such as the use of new cm-wave and mm-wave spectrum (6 to 100 GHz) and beam tracking of mobile users including the use of massive MIMO and beamforming techniques. We have also shown how latency targets for time-critical applications will be met by the use of shorter transmission time intervals and flexible TDD.
Furthermore Nokia Networks real-time Radio Resource Management for 5G systems has demonstrated seamless connectivity between 4G and 5G and shows an advanced view of how 4G can be integrated into 5G. That means different mobile generations and layers can be managed as one system.
Last but not least, extensive simulations have proven the ability of the set of proposed 5G technology enablers to boost network capacity 10,000-fold compared to 2010, to support scenarios such as connecting massive number of sensors, and to provide rock solid, low latency communications to enhance automotive safety and enable autonomous driving.
Next steps in 5G technology development
To drive 5G technology development further, Nokia Networks and NYU WIRELESS Research Center at the Polytechnic School of Engineering at New York University are jointly organizing the second annual Brooklyn 5G Summit in Brooklyn, NY on April 8 – 10, 2015. This year’s Summit will focus on spectrum assets above 6 GHz and progress in channel modeling at these higher frequencies. Further advances in Massive MIMO and Beamforming solutions for 5G systems will be a key topic at this Summit.
The event brings together industry R&D leaders in academia and business to further showcase and discuss the hottest 5G technologies. Following this great meeting of minds, we can certainly expect 5G to be one step closer to reality.
Nokia Networks’ featured speakers at the Brooklyn Summit include:
Hossein Moiin, Executive Vice President, Technology and Innovation
Lauri Oksanen, Vice President, Research and Technology,
Preben Mogensen , Principal Engineer and Head of research section Communications Networks, Aalborg University, Denmark and
Amitava Ghosh, Head, North America Radio Systems, Technology and Innovation Office, Nokia Networks
