Qualcomm reveals successful 5G mmWave data call test

Communications chip giant Qualcomm Technologies has taken an important step in its evolution of 5G systems by completing 5G data calls that successfully combine millimeter wave (mmWave) with FDD or TDD sub-6GHz spectrum by leveraging 5G standalone mode dual connectivity.

Using the Qualcomm Snapdragon X65 5G modem RF system of the fourth generation and the Qualcomm QTM545 mmWave antenna module in a smartphone form factor device, Qualcomm Technologies engineers collected 5G sub-6GHz FDD with 28GHz mmWave spectrum and then 5G sub-6GHz TDD with 39GHz mmWave spectrum.

This demonstrated the Snapdragon X65’s ability to combine low / mid and high bands across key global combinations, the company said.

The relevance of the test, Qualcomm said, was that spectrum aggregation, including dual connectivity using mmWave and sub-6GHz frequencies, is critical to delivering multi-gigabit speeds and the massive capacity required for a new generation. consumer and business applications.

It said combining different types of radio spectrum will enable 5G mobile devices to achieve wired broadband-class speeds wirelessly even in challenging conditions such as busy locations and transit hubs, and to power robust 5G fixed wireless access services in homes and small businesses. to provide.

“Qualcomm Technologies has continuously pioneered 5G solutions that can scale both performance and global reach,” said Durga Malladi, senior vice president and general manager, 4G / 5G at Qualcomm Technologies. “These milestones combine the massive bandwidth of mmWave with the coverage of sub-6 GHz FDD or TDD bands, enabling consumers and businesses around the world to get the most out of 5G networks and devices, especially in traditionally busy, bandwidth -hungry spaces. “

Qualcomm achieved the mmWave / sub-6GHz carrier aggregation milestones during data calls on March 17, 2021. Smart phone form factor devices equipped with the Snapdragon X65 successfully made data connections using Keysight Technologies’ 5G network emulation solutions, enhancing the global compatibility and interoperability of De Qualcomm systems with standalone 5G networks already deployed around the world.

According to the Global Mobile Suppliers Association, there are more than 100 commercial and pre-commercial 5G mmWave devices, ranging from phones and PCs to mobile hotspots, modules and consumer premises equipment, and virtually all of these devices are powered by the Snapdragon 5G modem -RF- systems.

Qualcomm Technologies is at the forefront of development and commercialization of 5G millimeter waves and is already sampling its fourth-generation mmWave chipset for smartphones. The company said the latest 5G modem RF system, Snapdragon X65, is the world’s first with peak speeds of up to 10 Gbps.

The Snapdragon X65 and Qualcomm QTM545mmWave antenna module are currently taking customer sampling, with commercial devices expected to launch later in 2021.
