Without wired internet at 50 meters. What to distribute?

Question

Computer networks

A small idea came to mind
. A friend lives nearby, 55 meters away (this is from the center of his roof to his granny)
From my room, from the window, direct visibility is his windows in the kitchen (45 meters + -1-2 meters)
Since he is permanently resident, the Internet is spent a long time
And now I'm thinking of linking our houses like
Bridges ?! NO, IT DOESN'T GO.... Since the distance is not 2 km I
expect somewhere around 3-4k rubles.
What is better to buy for such an amount?
He has an ASUS router, I don’t remember exactly what model - Well, it’s quite powerful (like Asus RT-N10)
I WILL SIT WITH A LAPTOP
Under its gate it catches 2-3 strips
In my granny’s room it catches on 1 stick as soon as I connect it immediately disappears
In the attached photo, the distance from the granny's roof to his roof. The
blue circles are my room and his
. Can I put one at the granny's Mikrotik SXT Lite2 as a "Client"? and connect it to the router
By making your own wi-fi at granny’s
I think it’s enough with my head
The reason for such an idea

spoiler

Хочу провести интернет до бабули
Сам у нее не часто нахожусь так как учусь в городе, приезжаю только на пятницу субботу и воскресенье
И вот как бы провести интернет - можно, НО
Цены провайдеры поставили:
За 25мб/с - 130грн (280рублей)
За 50мб/с - 150грн (320рублей)
За 100мб/с - 200грн (430рублей)
И + подключение 1500грн (3200рублей)
И из-за цены и то что я там не часто нахожусь (просто не кто им больше не пользуется)
Подключать интернет особо не горю

You can try this thing:

AC600 Outdoor Wi-Fi:

Perhaps this is more than you need, but fits your budget.

Answer 2

50 meters is not much. Almost any directional antenna will do.
The most budget option is from a coffee can . I'm not joking, this is really done very simply, and almost for nothing.
If you need better indicators, then you can buy a factory one, or do something like that .

Answer 3

Look at the ubiquiti hardware . Works great.

Answer 4

"Mikrotik SXT Lite2 as a "Client"? and connect it to the router. Make your own wi-fi at granny's"
This is an option that is both cheap and beautiful because there is no collective farm and Lite2, if necessary, where you can still use it.

Answer 5

Compare the monthly cost of the connected Internet and the total cost of the pieces of iron that you need to buy in order to distribute the Internet to you from a friend (most likely you will need 2 directional antennas). Your antennas will pay off in 2-3 years when compared with the cheapest connection option from the operator. Just connect your granny to the Internet and you can buy her a cheap tablet to hang out with her classmates.

Answer 6

Focusing nozzle on the WiFi antenna of the router
