Back in September last year, Qualcomm and Nokia announced plans to conduct interoperability testing and over-the-air field trials based on the 5G New Radio (NR) Release-15 specifications being developed by 3GPP. Today both the companies have announced that they have successfully completed interoperability testing in the 3.5Ghz and 28Ghz spectrum compliant with the global 3GPP 5G NR Release 15 standard using Nokia AirScale base station and device prototypes from Qualcomm Technologies. Nokia, Qualcomm Technologies and operators including BT/EE, Deutsche Telekom, Elisa, KT, LGU+, NTT DOCOMO, Optus, SKT, Telia and Vodafone Group are already committed to working together in verifying and trialing 5G NR technology. This will be based on the successful interoperability tests of the flexible 5G NR interface from Nokia and Qualcomm Technologies which will support a wide array of 5G services and various deployment scenarios. As announced last year, Nokia and Qualcomm Technologies continue working closely in driving the industry, leading to widescale 5G deployments in 2019 based on 3GPP standard-compliant 5G infrastructure and devices. This will enable timely commercial network launches in 2019, in particular in the United States, China, Japan, Korea and Europe. Source
