Finnish telecoms firm Nokia has announced a new 5G speed world record on equipment recently deployed commercially in the US. The over-the-air (OTA) network test took place in Dallas and reached speeds of 4.7Gbps.
The speed was achieved by combining eight 100MHz channels of the millimeter-wave spectrum on the 28GHz and 39GHz bands. This provided 800MHz of bandwidth and 40 MHz of LTE spectrum using the EN-DC functionality available on Nokia’s AirScale solution.
EN-DC allows for the end-user to connect to both 5G and LTE networks simultaneously, combining the two speeds into one. Nokia said the speeds were achieved on both 5G cloud-based and classic baseband configurations.

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 higher throughput than when connecting to 5G or LTE alone. The speeds were achieved on both 5G cloud-based (vRAN) and classic baseband configurations.
Stéphane Téral, the Chief Analyst at LightCounting Market Research, said: “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.”
Tommi Uitto, President of Mobile Networks at Nokia, commented: “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 are 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.”
