5G originally was planned to use 23GHz band which allows close to 100GB data rate for users. However due to technical difficulties on dense area implementations, the realization was delayed but Huawei supported a low band 6GHz system proposal and insisted on using it in China and European markets,hence the whole 5G was skewed and did not achieve original objectives.
@@蔡硬問 Huawei is the only dominate 5G OEM in the world. If your countries ban Huawei, mostly likely you don't have 5G. I live in the US, our 5G is more likely 4G+ when comparing to theoretically upload download speed to the 5G specs. Under developed countries like the ones in Africa and south America will see the most benefits setting up 5G.
