I am on the same boat, I live in a small Himalayan village. I have 2x5G based devices and one Wireless bridge (Ubiquiti LiteBeam M5) for a local broadband. Generally I get 50 Mbps, sometimes up to 100 Mbps
It's less of a pain now that I'm not in my LLM newbie phase of trying to test out 30 different models and stick with Qwen, but I couldn't even try to download qwen 3.8 for a week or two until I got back to the city.
Starlink is the obvious option and I have it on my roof but I do everything I can to not pay that $170 a month vs my $170/quarter 5g service.
