I live in a similar way in Canada, and I run long range ubiquiti radios (~12km) to nearest small town. get 150-200mbps and since I have battery backup + generator, usually the only reason it goes down is if the ISP router dies. I get ~1 bar of LTE that flickers to 3g, but with wifi calling it's not an issue. In addition to changing my own alternator, I run a small ISP for my neighbours :)
I'd like to know more about how you arranged this. In that small town, it sounds like you have some sort of connection to an ISP. Do you lease space on a tower to do that? Do you have a friend with an office nearby, and you connect there somehow? Is the ISP friendly and willing to set this up with you?
I have a 30m tower, and at the town I have a friend with a good connection. I rent roof space and pay half the bill. ISP is ok since it's a business plan, and both of us are using it for mainly business — it's similar to a shared office that provides internet from their perspective.
Only if by 'faster' you are referring exclusively to latency. In some situations (not all) you can achieve slightly better latency with wireless than fiber, but for raw throughout nothing compares to light in glass.
There are open comprehensive resources like the open book "WiFi networking in the developing world" [1] which seem pertinent here even though we're talking about North America. :P
12km isn't too bad actually for alignment unless you're using really high frequency (>10Ghz) equipment. Even then though you probably don't need specialized equipment other than maybe binoculars and a voltmeter[1]. I've taught beginners to align 24ghz radios at 12km by hand.
[1]The voltmeter is for quick feedback on the signal level as you aim. Many high-capacity wireless radios have a connection point on the back that will adjust voltage to match the current receive signal level (measured in dBm). That's usually the fastest way to watch the signal level as you aim, especially if you're hanging off a tower while you do it.
I spend a lot of downtime in what I thought was a very remote area of the Rockies. I learned many neighbors have been doing satellite Internet for years, though. Recently I started getting very good cell phone service, too. No other utilities, hardly accessible during the winter - but I can still check Hacker News.
My guess and not to answer for OP, but hughesnet or some type of satellite based internet. I know people who live far from broadband and cable and they all use hughesnet or something similar.
There is no cell reception, we have satellite, the ISP here in Canada is called Xplornet, which I believe uses Hughesnet. Download speed is pretty good, streaming services typically work fine with SD, voice comms. can be a bit of pain with the 700ms latency. Since covid-19 with many more people working from home etc. I have noticed a significant drop in bandwidth and how spikey latency can get at times.
I would guess satellite. I've lived in remote places before (but it was only 20 minutes to a big city mall, so not nearly as remote as described) and that is what I used. It was okay for most things, but the 600ms ping time to anything else sometimes was noticeable.
