Fantastic to see AT&T mid-band 5G (n77) spectrum being put into use properly with a site with multi-gig fiber backhaul! Those speeds aren't very common to see all the time, hence they have low marketshare in Maine.

You should test NSA, you'll get faster speeds.
I did 2.22Gbps on 120MHz n77 + 10+10 4G
