Can a wi-fi signal break through 4 solid walls in a brick house if you use directional antennas (12-16dB) and local access points? Situation: Internet is needed in a separate building, good cable Internet is available in a residential five-story building located across the road. Connection is possible only in the depths of the building, in an apartment, the windows of which, alas, face the opposite side. It is not possible to forward the cable for objective reasons, but it is not possible to put the antenna on the wall of the house (it is required to hide the fact that there is a high-speed connection in the building). The distance from the building to the brick house is 70 meters, the signal path inside the house is 15-20 meters, of which at least 3 main walls and 1-2 interior walls. It is supposed to use something like D-Link ANT24-1201 as antennas, routers as wi-fi points, I have not decided on the model, I hope for good advice. I also want to find out if this will not be firing a cannon at mosquitoes, maybe someone has experience using cheaper and simpler antennas and routers in such situations.

> put the antenna on the wall of the house - no (it is required to hide the fact that there is a high-speed connection in the building)
an external antenna at the focus of the rainbow-tv / tricolor / ntv + parabola will not help?
Is there an attic in a detached building?

I think you will see the network, but you will not be able to connect to it if you just point the antenna at the wall. Are there other buildings nearby? You need to make sure that the signal is reflected from other buildings and comes to you, and at the other point in the same way.

No, it can’t, you won’t even see a dot, unfortunately, it has been verified from our own experience and with fewer walls.

If there are no openings in the main wall on the signal path, then it is impossible.
In fact, in my organization, with the help of a directional antenna, 2 walls somehow break through, and then, in one of them, a recess of 20 cm (a window bricked up).

an antenna in an opaque plastic case is hung on the outer wall of the house and a cable is run to the apartment. the other side does the same. we get 2 antennas one opposite the other and no one knows that these are antennas.

may very well be able to. I have Asus Wl-500gP V2. breaks through 3 walls plus 30 meters from these walls brought out at home there is a distinct signal, it was checked on xperia x10, HP touchpad, galaxy gt. the walls are capital, almost 1.5 meters thick brick folds of each wall. although 70 meters is of course in question plus the road, a lot of third-party interference. even if you get a signal, it will disappear very often

Craftsmen make cheap directional antennas from tin coffee cans. I know the case with 10 megabits per 5 km (flashing + setting the signal power beyond the limit). Only I would be careful not to send such a signal through the neighbors ...
