Nokia has successfully completed an end-to-end 5G New Radio data call as part of a 5G research and development trial being carried out by the Chinese Ministry of Industry and Information Technology (MIIT).The Finnish vendor said that the 3GPP-compliant, dual-connectivity call was conducted using a 5G NR system over-the-air on the 3.5 GHz frequency band and LTE in the 2.1 GHz frequency band.

For existing 4G operators, dual connectivity will allow them to more rapidly create 5G coverage and services by connecting 5G NR to a 4G radio that is connected to an existing Cloud Packet Core. The successful 5G NR data call is an important step toward the verification of 5G in the sub-6 GHz frequency bands, which is required for wide-area coverage and massive IoT connectivity, in preparation for commercial deployment in China in 2020.

China, the world’s most populous country, will be one of the first adopters of 5G and a leader in the technology, which will deliver new possibilities for consumers and industries alike. For example, consumer entertainment will be enhanced by super-fast downloads of HD videos in seconds, and new virtual reality experiences will be made possible. 5G will also enable connectivity for billions of IoT devices, driving new levels of automation and the ability to leverage artificial intelligence to transform industries and economies.

The end-to-end data call used the Nokia AirScale Cloud RAN, Nokia AirScale baseband unit, Nokia 5G Massive MIMO Active Antenna, Nokia Cloud Packet Core and Nokia home subscriber service together with a 5G end user equipment simulator provided by PRISMA Telecom Testing. The Nokia AirFrame data center solution was used to control the Cloud RAN. Nokia will continue to work with MIIT through 2018 trialing 5G in the 4.9 GHz frequency bands.
