Qualcomm and Nokia said this week that they successfully tested nonstandalone 5G New Radio data calls over the air for interoperability, using both millimeter wave spectrum and sub-6 GHz.The tests were conducted at Nokia’s 5G center in Oulu, Finland and used Nokia AirScale base stations and a test device featuring Qualcomm’s X50 modem and antenna modules. The two companies called the testing “a continuation of their commitment to interoperability and OTA testing for the deployment of commercial 5G services in 2019,” nothing that they conducted additional 5G NR interoperability testing at 3.5 GHz and 28 GHz in February. “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,” they added.Also this week, Samsung, Qualcomm and Verizon touted a 5G NR data connection that reached 1.7 Gbps, leveraging 400 MHz of bandwidth at 28 GHz. The nonstandalone 5G demo, conducted at Qualcomm’s San Diego labs, used a smartphone test device and dual connectivity; it relied on Samsung’s 5G NR and 4G LTE equipment, Verizon’s spectrum and a test smartphone-type device with Qualcomm’s Snapdragon X50 5G modem and antenna modules. -5G and internet of things company Inseego said that its 5G New Radio mobile network devices have “surpassed all performance objectives” in a live network 5G NR millimeter wave field trial with Verizon.
