WiFi mesh networks can have impressive range outdoors, without walls and reflections blocking the wifis. And they can be powered by PoE (Power over Ethernet) so you only need to run 1 cable to hook it up.

But for most of my work, a cellphone hotspot is suitable, so long as it's not so remote that I don't get at least a strong 4G signal. Video conferencing isn't very data intensive with compression and, if I'm not running the meeting, slight spottiness is fine.

Working outside your home is nice. But I think a lot of these comments are talking about working outside in public is a whole other problem.
