Reply to comment by Cryptolution in A new novel antenna bringing us closer to 6G wireless communications by Vailhem

That’s a very simplistic way of looking at it. The entire network architecture has been changed with 5G. Aside from the millimeter wave bands, most of the rest are compatible with LTE. 5G also brings many enhancements like power saving, decreased latency, and support for massive IoT.

Yes most future tech has legacy bridges built in, so I suppose you would be correct in the sense that 5g deployment brings additional 4g coverage.

There are evolutionary cellular technologies. The intention is to shift away from 4G over the next 5-10 years. The same thing happened with 3G. You should think in terms of overall cellular coverage. As it is, a 5G-capable phone can simultaneously transmit and receive on 4G and 5G cells, so it’s literally an expansion of current 4G service.
