This is the list of features:

The list of bands seems long, much longer than what my eye is used to. 
It is an expression of new chips extremely parametrable and generic.

The band 71 seems to have inside some specifics to 5G, somewhere in the 
UHF (hundreds of megahertz).

The bands 42 and 48 are in the 3.5GHz area.  The 3.5GHz are is where it 
is likely that some bands are to be allocated for 5G in France.

(other likely 5G frequencies are in the UHF, in 20-something GHz, 
60-something and 70-something).

It is for these reasons I believe iphone 11 is ready for 5G.
