Nokia successfully completes 5G NR data call with 4G and 5G dual connectivity in China

The dual connectivity will allow the existing 4G operators 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.

Nokia today announced the successful completion of an end-to-end 5G New Radio (5G NR) data call as part of a Chinese Ministry of Industry and Information Technology (MIIT) 5G Technology R&D trial and will continue to work with MIIT through 2018 trialing 5G in the 4.9 GHz frequency bands.

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.

As per the company, the 3GPP-compliant dual connectivity call was conducted using a 5G NR system over-the-air on the 3.5GHz frequency band and LTE in the 2.1 GHz frequency band, supported by a 5G user equipment simulator provided by PRISMA Telecom Testing.

"We are pleased to showcase our end-to-end capabilities in 5G in this successful call and trial with MIIT. Nokia is ready to support dual connectivity with the AirScale radio access portfolio as it is upgradeable via software to 5G and provides single RAN support for 4G, 4.5G Pro and 4.9G as well as legacy technologies. As a result we can help our customers meet their early 5G deployment schedules and initial coverage demands," said Marc Rouanne, president of Mobile Networks at Nokia.

The dual connectivity will allow the existing 4G operators 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.

Nokia told that the data call used Nokia's 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.
