I recently read an article in the New York Times where the writer tested 
a few 5G smartphones on some cellular networks and some places in USA.

He said that 5G bandwidth looked higher than 4G+ to him in some places 
but he felt that better in open areas rather than indoors.  It was not 
significantly higher, just a little bit higher.

I think what 5G needs is these intelligent reflecting surfaces which 
might help increase coverage in a more energy-efficient manner, maybe 
less risky for health, and avoid somehow in some cases societal opposition.

We cant dream about hundred Gbit/s bandwidths for IP on 6G if the 
increase from 4G to 5G bandwidths is not at leastten times more.

If 4G is 50Mbit/s and 5G is 100Mbit/s then we cant expect 6G to be 
100GBit/s.
