Techies are also confused. Several times I have heard the claim that 5G only works millimeter wave range and it's only for high density cities. 5G NG goes from 410 MHz to 52.6 GHz. Sub-1 GHz is for coverage wide coverage across suburban and rural areas and help IoT services. NG encoding is somewhat more computationally expensive in the device, but has more efficient transmission. The bet is that microprocessors continue to become more energy efficient in the future. Energy efficiency of base stations in the rural areas is big thing going for 5G.
