Qualcomm Announces Successful Data Calls Using 5G mmWave, Sub-6 GHz

Qualcomm said it completed 5G data calls combining millimeter wave with frequency-division duplexing or time division duplex sub-6 GHz spectrum by using 5G stand-alone mode dual connectivity. It combined the company's Snapdragon X65 5G Modem-RF system and QTM545 mmWave antenna module inside a smartphone form-factor device, demonstrating the ability to aggregate low, mid- and high bands across global combinations, said the company Tuesday. Spectrum aggregation, including dual connectivity using mmWave and sub-6 GHz frequencies, is “critical to delivering multi-Gigabit speeds and massive capacity required for a new generation of consumer and enterprise applications,” said the company. Combining different types of radio spectrum will enable mobile 5G devices to achieve wired broadband-class speeds, even in challenging conditions such as crowded venues and transit hubs, it said.
