Finnish vendor Nokia and Sonera, the Finnish subsidiary of Telia Company, have revealed details of key trials which they claim underline ‘the leading role they are playing in bringing next-generation communications to market’. In a press release the duo confirmed that last month they undertook trials at Sonera’s headquarters in Helsinki of both 5G mobile networking and new copper cable technologies capable of delivering data speeds of up to 10Gbps. With regard to the former, it was noted that 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 utilised the 4.5GHz frequency band, with downlink speeds over 4.5Gbps recorded. Meanwhile, Sonera said it had also tested Nokia’s XG-FAST solution, a fixed broadband technology developed by Nokia Bell Labs which allows existing copper cables to deliver transmission speeds of up to 10Gbps via traditional copper cable. Alongside the aforementioned trials, it was also noted that Sonera and Nokia had recently trialed small cell technology to boost network capacity at the Flow Festival, a music festival held in Helsinki last month.
These demonstrations follow a cooperation agreement signed between Telia Company and Nokia in July this year which aims to accelerate Sonera’s network evolution to 5G. As part of this contract, Sonera and Nokia will carry out further tests to enable early 5G readiness and to secure early introduction of commercial 5G services for Sonera customers.
Commenting on the developments, Timo Hietalahti, head of Network Architecture and Development at Sonera, was cited as saying: ‘Combining mobile and fixed technologies, and making sure those technologies function well together, is more important than ever in future network solutions. 5G has a key role in the Internet of Things and virtual reality solutions, and in order to provide for the explosive growth of mobile traffic we see already now, all technologies allowing us to best utilize fixed networks are needed. Nokia is our longstanding technology partner, and it will play a critical role in our path to 5G.’
