Nokia has announced it has been collaborating with Finland’s dominant mobile network operator Sonera on the development of 5G mobile networking.
The firms have said they are demonstrating the role of fixed and mobile networking technologies on the path to 5G.
They have been conducting trials at Sonera headquarters in Helsinki, Finland, of both 5G mobile networking and new copper cable technologies capable of delivering data speeds of up to ten Gb/s.
Carried out in August, the trial was built around a 5G-ready network using the commercially available Nokia AirScale Base Station and a core network solution. The high-speed, low-latency 5G network was used to deliver high resolution video footage shot using OZO, Nokia's virtual reality camera intended for professionals.
Using the 4.5 GHz frequency, this aspect of the trial reached data throughput speeds of over 4.5 Gb/s.
Sonera also tested Nokia's XG-FAST solution, the fixed broadband technology which allows existing copper cables to deliver high-speed fixed broadband, which will save service providers having to install new cabling.
XG-FAST technology can reach transmission speeds of up to ten Gb/s in a traditional copper cable and is intended for short copper loops. Therefore, it is suited for projects related to FTTB (fibre to the basement), for example.
Nokia said that using the XG-FAST technology “makes sense” when a high-speed connection is required over a large area quickly and cost-effectively, using existing copper cables.
Timo Hietalahti, Sonera’s head of network architecture and development, said: “Combining mobile and fixed technologies, and making sure those technologies function well together, is more important than ever in future network solutions.”
He added that 5G will be key to the Internet of Things and virtual reality solutions, explaining that in order to provide for the “explosive growth of mobile traffic we see already now”, technologies allowing developers to best utilise fixed networks are needed.
Sonera and Nokia recently also carried out trials on small cell technology to boost network capacity at a music festival held in Helsinki. Small cells – which can increase capacity efficiently in a variety of areas – are expected to play a key role in future 5G networks, meeting their needs for increased capacity and lower latency.
