How is 6G different from 5G?

Both 5G and 6G take advantage of higher frequencies on the wireless spectrum to transmit more data, faster . However, 5G occupies broadband frequencies at sub-6 gigahertz (GHz) and above 24.25 GHz – called low band and high band frequencies respectively. 6G will operate at 95 GHz to 3 terahertz (THz).9 Mar 2020

6G will be 50 times faster than 5G, 100 times more reliable, offer wider coverage and support ten times more devices per square kilometer . With that kind of speed and power, it’s hard to say exactly what the 6G architecture will look like. Early discussions predict advanced levels of automation and connectivity.

6G might eventually approach the upper limits of the radio spectrum and reach extremely high frequency levels of 300 GHz , or even terahertz ranges. However, just like we’re seeing now with 5G networks being extremely localized due to the inherent limits of millimeter waves, the same problem will be seen in 6G networks.
