Utilising 800 MHz of commercial millimeter wave 5G spectrum and Dual Connectivity (EN-DC) functionality, Nokia says it achieved 5G speeds of up to 4.7 Gbps.
Nokia says the record speed was achieved by combining eight 100 MHz channels of millimeter wave spectrum on the 28 GHz and 39GHz bands, providing 800 MHz of bandwidth, and 40 MHz of LTE spectrum using the EN-DC functionality available on its AirScale solution.
EN-DC allows devices to connect simultaneously to 5G and LTE networks, transmitting and receiving data across both air-interface technologies, which Nokia says means devices can achieve a higher throughput than when connecting to 5G or LTE alone.
Nokia says the speeds were achieved on both 5G cloud-based (vRAN) and classic baseband configurations.
According to Nokia, this solution will not only provide subscribers with “unrivalled mobile broadband speeds, but also enable carriers to sell various latency-sensitive enterprise services, such as network slicing for mission-critical applications”.
Tommi Uitto, President of Mobile Networks at Nokia, said, “This is an important and significant milestone in the development of 5G services in the U.S, particularly at a time when connectivity and capacity is so crucial”.
“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.”
According to Stéphane Téral, Chief Analyst at LightCounting Market Research, “This is a substantial achievement that 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.”
