Qualcomm and Nokia have successfully achieved over-the-air (OTA) 5G NR data calls in both the mmWave and sub-6 GHz spectrum bands. Compliant with the global 3GPP 5G NR Release 15 specification in NSA (Non-Standalone) mode, the interoperability testing milestones were completed at Nokia’s 5G center of excellence in Oulu, Finland. The tests used commercially available Nokia AirScale base stations and a mobile smartphone form-factor test device powered by the Qualcomm Snapdragon X50 5G modem and antenna modules with integrated RF transceivers, front-ends and antenna elements.
The test carried out by the two companies are a continuation of their commitment to interoperability and OTA testing for the deployment of commercial 5G services in 2019. In February 2018, Nokia and Qualcomm Technologies first completed key 3GPP-compliant 5G NR interoperability testing in the 3.5 GHz and 28 GHz spectrum bands using a commercially available Nokia AirScale base station and device prototypes from Qualcomm Technologies. The OTA calls are key steps in enabling customers in the 5G ecosystem to launch commercial networks and mobile devices from early 2019 onwards, in the United States, Korea, Europe, Australia, Japan and China.
