What equipment is needed to connect two computers via WIFI at a distance of 200 m?

Question

WiFi

The cheapest. And how to connect all this?

Answer 1

We need WiFi devices with twisting antennas, an adapter for a thick cable (SMA -> N-Type), a thick cable itself (in a thick cable, for which N-Type connectors are intended, there is less signal attenuation per meter of cable, and antennas usually need to be hung outdoors , yeah!), N-Type connectors on the cable, a tube of sealant and the antennas themselves.
Devices are first configured next to each other as you need (AP<->APClient, AP-Bridge is up to you, just don't forget to turn on encryption and turn off fucking WPS).
After that, SMA antennas are twisted from the devices (a thin connector that usually stands on household access points), we wind the SMA-> N-Type adapter, a terminated N-Type cable on it, and an antenna on the cable.
Sealant is MANDATORY to cover the N-Type connection that is outside next to the antenna.
The antennas themselves should be taken from 18 dBi and above (200 meters, yeah!) DIRECTIONAL!.
Antennas should be oriented towards each other and in the same plane (if the antennas are polarized).
And that's all.
We have sculpted such air bridges more than once. Works for years.
PS: Or, instead of all of the above, buy normal external APs (but this is not cheap).
