Which signal amplifier to buy? How to organize a network?

Question

Computer networks

Comrades, tell me, please, the situation is as follows:
There is a holiday village, but it has only 3G (marked with a dot)
There are 4G in 3.3 KM.
What kind of active signal amplifier to buy in order to get the same normal Internet.

Answer 1

The antenna is the best amplifier.
To get started, assemble yourself any directional antenna for 3 / 4G, of which there are a huge number on the Internet. If you are too lazy to collect, then buy an antenna like Uda-Yaga or a dish.
Line of sight (and Fresnel zone) is desirable. You can see the route route here: linktest.ru
You will succeed if you make a little effort :)
