Nokia has set a new record for the fastest 5G velocities in the world, breaking Ericsson's previous record only a few months earlier.
Using dual connectivity enables operators to transmit data simultaneously across 5G and 4G networks, achieving higher transmission rates than using either technology independently.
By comparison, Nokia was using a real OTA network deployment.
The Finnish company reached speeds of 4.7 Gbps at its Over-the-Air (OTA) network in Dallas, Texas, set by Ericsson by 0.4 Gbps. In February, the Swedish telecoms giant announced it had achieved what was then the world record speed of 4.3Gbps.
Nokia was able to achieve the speeds by pairing eight 100 MHz channels of millimeter wave spectrum on the 28 GHz and 39GHz bands, providing 800 MHz of bandwidth, with 40 MHz of LTE spectrum using the EN-DC functionality available on Nokia’s AirScale solution.
Nokia said this test, which was carried out on the network of an unnamed “major US carrier”, shows that 5G could not only provide subscribers with “unrivalled mobile broadband speeds”, but will also enable carriers to provide latency-sensitive services such as network slicing for mission-critical applications.
This is an important and significant milestone in the development of 5G services in the US, particularly at a time when connectivity and capacity is so crucial.
-Nokia’s president of mobile networks Tommi Uitto.
It demonstrates the confidence operators have in our global end-to-end portfolio and the progress we have made to deliver the best possible 5G experiences to customers. We already supply our mmWave radios to all of the major US carriers and we look forward to continuing to work closely with them moving forward. Commenting on the milestone, Stephane Teral, Chief Analyst at Light Counting Market Research, said the achievement
Reflects the careful workings of a brilliant and subtle team with the deepest appreciation for detail and circumstance.
In other words, 8-component carrier aggregation in the millimeter wave domain shows the world that there is more than massive MIMO and open RAN to not only truly deliver the promise of commercial 5G, but also pave the way for future Terahertz system.
It’s worth noting that Samsung recently claimed a significantly of 8.5Gbps using a similar setup, though this was achieved in a limited indoor lab test. By comparison, Nokia was using a real OTA network deployment.
