Nokia says it has achieved the world’s fastest 5G speeds in its Over-the-Air (OTA) network in Dallas, Texas. Utilising 800 MHz of commercial millimetre wave 5G spectrum and Dual Connectivity (EN-DC) functionality, Nokia achieved 5G speeds of up to 4.7 Gbps in tests performed on base station equipment being deployed in major US carriers’ commercial networks.
According to Nokia, the 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.
The record speed was achieved by combining eight 100 MHz channels of millimetre 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 Nokia’s AirScale solution. EN-DC allows devices to connect simultaneously to 5G and LTE networks, transmitting and receiving data across both air-interface technologies. This means devices can achieve a higher throughput than when connecting to 5G or LTE alone. The speeds were achieved on both 5G cloud-based (vRAN) and classic baseband configurations.
“This is a substantial achievement that reflects the careful workings of a brilliant and subtle team with the deepest appreciation for detail and circumstance,” declared Stéphane Téral, Chief Analyst at LightCounting Market Research. “In other words, 8-component carrier aggregation in the millimetre 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.”
“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,” added Tommi Uitto, President of Mobile Networks at Nokia. “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.”
