5G seems to be the topic of the moment. I’m not even using 4G myself yet, so it seems like a far off subject. Then again, 7 years ago Facebook was only just opening up to the public and iPhone was yet to enter the market. Today they are an integral part of many people’s lives. Dare I say, they are the epitome of the change in mobile usage. And although 4G is still in its infancy, it is being adopted faster than any previous mobile broadband technology.
I can’t imagine what changes will occur over the next seven years, but we at Nokia Siemens Networks expect that the increasing data usage and the demand for better mobile broadband experience mean that mobile networks will have to profitably deliver 1 gigabyte of personalized data per user per day by 2020.
The industry needs to figure out how networks can be readied to meet these demands of extreme capacity and performance in the future. We believe LTE and LTE evolution technologies together with small cells should be able address the upcoming capacity needs in the mid-term. But our propeller heads are also looking into what will become after that.
5G is one key area of innovation. It will be an evolution from 4G – not a completely new wide area radio technology. 5G is not yet standardized, but we already know it’s about better local area performance, lower latency and ultra dense HetNets. Nokia Siemens Networks believes 5G will be complementary to wide area wireless access technologies such as LTE/LTE-A and could be slated for deployments after 2020.
Examples of Nokia Siemens Networks 5G research include the world’s first live Authorized Shared Access (ASA) trial in Finland to dynamically access unused spectrum. We have already demonstrated how our Small Cell Integrated Backhaul Antenna radically simplifies deployment of small cells and meets backhaul challenges. Also in the area of small cells, we are heading the HetNet stream in METIS, an EU funded 5G research project.
But preparing for the future requires the industry looks at other key areas than just 5G. Nokia Siemens Networks has identified six technology pillars to provide a clear direction to address future challenges. These pillars form the Nokia Siemens Networks Technology Vision 2020:
• Enabling 1000 more radio capacity
• Reducing latency to milliseconds
• Teaching networks to be self-aware
• Enabling ultra-personalized services
• Reinventing telco for the cloud
• Flattening total energy consumption
Stay tuned for deep dives into each pillar in the coming months.
