Authored by Claudio Casetti

On 24 August 2022, it was announced that NTT Docomo launched the world’s first commercial 5G SA network, allowing smartphones to simultaneously utilize both midband (sub-6 GHz) and millimeter-wave (mm-wave) frequencies, also known as 5G New Radio (NR) Dual Connectivity (DC).

Users with the Sharp AQUOS R7, Samsung Galaxy S22, Samsung Galaxy S22 Ultra, and Sony Xperia 1 IV—all powered by Qualcomm’s Snapdragon 8 Gen 1 Mobile Platform, which features the Snapdragon X65 5G Modem-RF System—are already seeing downloads of up to 4.9 Gb/s and uploads of up to 1.1 Gb/s, including in crowded areas.

Thanks to the speed, reliability, and power of 5G NR-DC, customers with these four devices can access high-speed service in congested areas, notably, major terminal stations; event venues, including stadiums; and commercial facilities.
