Is this the band that has really really short range for 5G? If so, it

This is the C-band spectrum near 4GHz. The super short-range (or,
rather, highly direction and subject to attenuation by almost
anything) that you're probably thinking of is likely the UWB mmWave
band up at ~30GHz.
C-band has moderate structure penetration and limited foliage
penetration. With line of sight and at the power levels the carriers
would consider running, several miles of usable range would be
unsurprising, though I suspect many typical deployments would have
design cells smaller than that while using existing "4g" (and newly
opened ex-TV broadcast space) low- and mid-band frequencies for wider
area coverage at reduced speeds. Interference considerations,
especially high above the horizon (planes...) would be present for
potentially dozens of miles away.
An article I read said that other countries are accommodating them. What
are they doing different?
