Qualcomm Technologies has announced the completion of 5G data calls that successfully combine millimeter wave (mmWave) with FDD or TDD sub-6GHz spectrum by utilizing 5G Standalone (SA) mode Dual Connectivity. Using the 4th-generation Qualcomm® Snapdragon™ X65 5G Modem-RF System and Qualcomm® QTM545 mmWave Antenna Module inside a smartphone form-factor device, engineers from Qualcomm Technologies first aggregated 5G sub-6 GHz FDD with 28 GHz mmWave spectrum, then 5G sub-6-GHz TDD with 39 GHz mmWave spectrum, demonstrating Snapdragon X65’s ability to aggregate low-/mid- and high-bands across key global combinations.
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. Combining different types of radio spectrum will enable mobile 5G devices to wirelessly achieve wired broadband-class speeds, even in challenging conditions such as crowded venues and transit hubs, in addition to powering robust 5G fixed wireless access services in homes and small businesses.
“As the world’s leading wireless innovator, Qualcomm Technologies has continuously pioneered 5G capable of scaling in both performance and global reach,” said Durga Malladi, senior vice president and general manager, 4G/5G, Qualcomm Technologies, Inc. “These milestones combine the massive bandwidth of mmWave with the coverage of sub-6 GHz FDD or TDD bands, enabling consumers and enterprises across the globe to make the most of 5G networks and devices, especially in traditionally congested, bandwidth-hungry spaces.”
