What do you guys think about this: https://www.ubnt.com/

From what I understand you can use this to build a private wireless internet?

would be interesting to build something like this for our settlement and communicate out of reach from prying eyes

I have something similar at my house. It's essentially an infinitely expandable network.

With modules that can go all over extending your wifi without duplicating the ssid.

It's handy, but expensive.

what do you use it for if you dont mind me asking

Well, the primary point of it is range extension, I have a fairly long house, even the most expensive routers wont cover it.

*consumer routers

But theres securuty and convenience reasons as well.

*security

They have a unified interface, which allows for control of the network as a whole, rather than having to set up individual access points.

Which is a pain.

can it really extend 15km out like it claims?

They have finely granulated permissions and policy controls as well, much moreso than the average home router.

With enough modules, sure.

Or with high powered directional transmitters and recievers.

do you think this could come in handy in a settlement, for members to communicate securely?

As long as it was kept isolated from the web, otherwise it isn't 100% secure.

And most any wifi has vulnerabilities.

If someone has the encryption keys and is in range.

Wifi is generally not your best option if security is your main priority.

but being in range is already a major obstacle no?

plus you would need to know it even exists

Depends on where you are I suppose.

To hack a wifi network, yes you have to be physically in range, so if you can keep outsiders far enough away, it would be ok.
