Several 5G smartphones based on Snapdragon 855 processor and Snapdragon X50 5G modem have been announced, but AFAIK none have shipped to end users. But Qualcomm has already announced their second generation 5G NR (New Radio) modem with Snapdragon X55, which the company claims is “the world’s most advanced commercial multimode 5G modem”.
Manufactured with a 7-nm process, Snapdragon X55 is a single-chip modem that supports 2G, 3G, 4G, and 5G NR mmWave and sub-6 GHz spectrum bands with up to 7 Gbps download speeds and 3 Gbps upload speeds over 5G, and up to 2.5 Gbps download speeds over LTE (Category 22)
The model supports TDD and FDD modes, is capable of Standalone (SA) and non-standalone (NSA) network deployments, and can handle dynamic spectrum sharing delivering both 4G & 5G services dynamically.
The modem will not only be found in 5G smartphones, but a wide range of devices including mobile hotspots, always connected PCs, laptops, tablets, fixed wireless access points, extended reality devices, and automotive applications.
