It depends on the conditions Cables are always the winner, but I have an off grid cabin that has very poor cell reception. I usually end up getting less than 2 Mbps.
But my parents live about 400 meters away and have FTTH, in the countryside, because of a local cooperative.
I looked for using a fibre but it would cost several hundred dollars to have one that resists outdoor conditions in Quebec for a few years. So I settled for Wi-Fi. I get 10 Mbps with the two repeaters and very basic antenna alignment, which is better than 2.
I’d really like to use a cable but I’m only there a few weeks a year, so this works ok.



I thought about Ethernet but apparently the run is too long, even with repeaters. It will probably not have enough power. It’s also a few hundred dollars for 400 meters of direct burial Ethernet cable, without counting the injectors and repeaters.
And most importantly, I wonder how the equipment would fare during winter when the ground is frozen solid for several months.
But maybe my fear of a few -25°C days is not justified, as I already left a Raspberry Pi in a barn with those temperatures, and it did fine. I’d have to check the temperature operating range for the equipment I use.
That’s why in the end, if I have to use a cable, I was leaning towards direct burial fibre, as it can easily cover that distance without messing with PoE on long runs, would “only” cost a few hundred dollars more, and avoid the need to try to protect the repeaters/switches.
I’m still curious though, so I guess I could just try it for fun with a cheap Ethernet cable run for a summer, then see if it’s really worth investing a bit more for the future.
