There are some amateur radio operators who operate in QRP (max. 5 W power) and have a DXCC award (so they have contacted at least 100 different countries). So the range is much more than 80 km, especially if you use digital modes able to recover signals you can't even hear (like FT8 or WSPR)... but bandwidth will be very low.

It is a deep rabbit hole, but in the spirit of comparing apples-to-apples... Also, the ERP limits on FCC stamped consumer modules is fairly low for unlicensed users. i.e. many Lora modules have iffy certified antennas for compliance reasons. Cheers, =3
