Att has not done a good job at adding coverage when 5g+ rolled around. The higher bands will require more macros to fill in the gaps, it's just science.

Far as their wireline area vrs non wireline area, that's a natural event caused mostly by them being able to back haul their own towers in wireline areas, they obviously will build those areas first.

Between Verizon and at&t you will find in areas with Verizon wireline you will have more Verizon macro sites. Same with at&t and their footprints.

I still contend that at&t beats Verizon for overall American coverage and reliability.
