How to establish a link for 2 km without line of sight?

Question

WiFi

It is necessary to establish a Wi-fi link at a distance of 2 km. There is no direct visibility, there is a brick house on the way. Is it possible to?

Answer 1

In fact, there are antennas with a gain of more than 20 dB, and they can work for 20 km (with line of sight). Maybe they will be able to break through a brick house for 2 km. I have a socket (it's reinforced concrete, it's worse than a brick). At home, I see about 15 networks (this is at least a couple more neighboring entrances). So Wi-Fi even breaks through several reinforced concrete walls. It's easier with a brick.

Answer 2

Unfortunately no.

Answer 3

You can try through the repeater, ie. to go around your brick house, though you need to agree with the person on whose building the repeater will be installed.

Answer 4

Nothing prevents you from putting an intermediate Wi-Fi on the roof of the house, and you can also have a mast for direct visibility.
