Consolidation of offices on wifi?

WiFi

The office expands and 4 people move into the next building. The buildings are located perpendicular to each other (the legs of the triangle). The distance between the offices is ~100 meters directly, but there are about 6 thick brick walls between them (old building). There is an option to pay money to the provider and blame the network laying on him, but there is an irresistible desire to unite offices over the air. Question for knowledgeable people:
will wifi break through these walls, what power of transmitters / antennas at access points is sufficient in this case? There is no test equipment, the purchase for the sake of experiment will not be approved by the authorities.
UPD. If someone had a similar task, share your experience, at what distances and what equipment was used. I don't want to give up so easily, maybe there are other solutions.
UPD2.Another piece of advice came by telegraph:
“I had a similar problem a couple of times and both times we looked at a lot of things, but considering that the offices are small, there is no money for their reliable channels, and WiFi is in mode (here is a router for 3k and there is a router for 3k) do not earn did a trace. way: We bought 2 connections from one provider (each office has its own connection with its own contract) and made a channel (VPN) already through the provider's network (without access to the Internet). That is, relatively speaking, it turns out at the head office ip 10.10.5.15, and in the additional 10.10.5.18. In addition, we set up VPN in the head office, and disable everything except VPN. That is, everyone goes to the Internet through the head office (usually the tariffs are better this way).
As a result, we have almost “one hundred megabits” (it strongly depends on the provider’s equipment along the route, our version gives out 50-70 megabits freely) and the reliability is much higher than the “cheap access point” layout - it’s not clear how the powered repeater * n pcs. — one more access point“”
Thanks to Unknown ))
UPD3. I listened to the advice not to create problems by connecting via wi-fi to either myself or future admins. The issue was resolved according to the scheme described in UPD2.
Thanks to all.

Do not create headaches for yourself and future admins. If it breaks through, then you are unlikely to get joy from such a connection. As for a certain super wi-fi - I have not heard. Perhaps you are talking about wi-max? True, equipment of such a plan will cost you a pretty penny

The best option from experience: not wi-fi and not copper. Lay single strand optics in Kevlar through the air.

Similarly, I do not advise making a channel through the air, if it is not temporary. Even if it breaks through, then there will be no problems if one more obstacle "suddenly" grows in addition to 6 brick walls.

6 brick walls will not break through in any way. I have 70 meters in my office, the walls are mostly cardboard. And it barely succeeds! I had to drag the cable and put another point.

It will work, you only need to ask for more powerful equipment when buying, tell the consultants in detail what you would like and they will advise you on the best option

What if you put the antenna out the window?

As an option, there are amplifiers (you can look on eBay), but here the question of strong radiation arises.

One repeater can solve the stability problem, I think.

Raised 5 kilometers in line of sight with directional antennas, 22Mbps in snow and rain, 36+ in clear weather.
Most likely it won’t break through the walls, but if you force them to break through, then fry everyone along the signal path :)
Kevlar and other protection if done for decades, if 10 megabits is enough, then you can use an ordinary tepekha - it’s enough for 3-5 years on the street (the first a year for 100m and a hundred will give out, then it degrades).
In general, I would not advise to be weird with wireless technologies.
