Watch out, it's 100% possible to do long ranges over WiFi but the speed tradeoff at long distances can be significant. Devices made for long-range use will either autoselect or allow you to manually select an encoding, which will need to be lower-rate as the range increases. Documentation often gives radio performance values for different encodings, e.g. the Mikrotik DISC Lite5 gives Tx and Rx specs starting from 6Mbps (essentially 802.11a) up to MCS9 (256 QAM) which can do well over a gigabit. We can do some naive calculations to estimate that MCS9 is achievable at up to 5km (really pushing it) while 6Mbps works out to 50km or more! In practice there are other factors that will limit these because you start getting into fresnel zones and such, especially as you get over a few km. The Ubiquiti devices are a bit more expensive but are easier to work with than Mikrotik. They also have higher-end options available for very long range use, 50-100km type scenarios, although the data rate gets very low.
