Nokia says that it has achieved 5G data speeds of 4.7 Gbps, which it says is the fastest over-the air (OTA) speed yet transmitted. The testing, which was conducted in Dallas, used 800 MHz of commercial millimeter wave spectrum and dual connectivity (EN-DC) functionality.

The 4.7 Gbps speed used base station equipment that is now in deployment in major carrier networks in the U.S.

What is EN-DC?

The method used to achieve the speed was the combination of eight 100 MHz channels of millimeter wave spectrum on the 28 GHz and 39 GHz bands and 40 MHz of LTE spectrum using EN-DC functionality in Nokia’s AirScale platform. EN-DC enables devices to simultaneously transmit and receive data across 5G and LTE networks. The high speeds were achieved on both 5G cloud-based (vRAN) and classic baseband configurations, the company 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,” Tommi Uitto, Nokia’s president of Mobile Networks, said in a press release. “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.”
