How to create a stable wi-fi network in a country house?

Given:
a 3-storey wooden house with an area of ​​about 330 sq.m., + a plot of 10 acres.
The house is located in a village where there is only unstable 3g from two of the three big three operators (yes, I know that 3g is not enough for comfortable use).
Task: to create a wi-fi network (+ stable Internet, in the long term - the creation of IP video surveillance with the ability to connect to a network from another city), which could be used throughout the territory.
Usage model: mail, social networks, youtube videos, sometimes movies maximum 720p for 4 people (this is to understand the load).
Nuance: there is no possibility to lay cables through the floor / ceiling / walls.
Can you tell me how to solve this problem?
From the equipment at the moment there is only an old ZyXEL Keenetic 4G (does it make sense to use it somehow?)

Firstly, you need an antenna for good 3/4 G reception.

Secondly, you need a router or modem, or both, with a connector for an external antenna.
Thirdly , with such requests and the described house, you will need 3-4 access points or directional antennas for Wi-fi. Anyway. Ubiquiti-for example, Mikrotik is now advised, but then you will need a pro to boot.
Fourth, you need to know the signal coverage area from the cell tower and the direction to it.
Fifthly , for laying the Internet at home, there are different options for PlC, Powerline equipment, which transmit the Internet over the wires of the 220V home network.

They can be connected via wi-fi, cable. They can replace access points, the number of devices can be increased according to the star scheme.
Sixth , as mentioned above, without a cable connection, the volume of Internet consumption will be limited to a TV, or one computer, or a couple of tablets, and then, just surfing, be realistic.
Seventhly , video surveillance can be connected, but laying cables around the house is "forbidden", PLC - theoretically pulls, in practice there may be problems. Forget Wi-Fi. Craftsmen are able to compress a picture transmitted remotely to a channel of 512 Kbps of outgoing traffic for 16 cameras, but 1 frame per second / max, at low resolution.
Eighth, if it is not possible to use a cable, you can organize a pair of + antennas and a pair of + routers and networks - to increase throughput.
For example, one network for surfing, another for video, and a third for video surveillance.
Ninthly , the signal may not be so bad and 4G will suddenly show up.
Good luck. My website www.konbez.com

Almost all CIS countries have satellite Internet operators. This is more reliable than 3g, but the ping will be higher. For ip video surveillance, watching video is enough.
wifi in a wooden house seems to be easier than in reinforced concrete. Several routers in repeater mode can cover everything, see how to arrange it on the spot.

Seamless viwai uni-fi ubiquity! Here are those solution.
Don't look at Mikrotik just yet. It will be very cheap.
As for the satellite, they advised above ... Are you there? At all?. Renting 1 megahertz of a carrier frequency cost 1k usd a few years ago, which is, by the way, 2 megabits. Well, if you are ready to give from 30..40 thousand rubles for an Internet per month, then another conversation.
And access from the outside: they already said above, 4g + switch is normal (ideally poe - for uni-fi) + antenna amplifier 3 / 4g + nanocomputer as a uni-fi controller.
Zyxel will come in handy.
About video ... Many cameras can communicate via p2p, only their serial number is needed. Camera IP is optional. An ahd video recorder with p2p and a Chinese xmeye service is quite enough.

1) You need to find out which operator has 4g.
2) Only the megaphone has 4g with an external ip
3) An external 4g mimo antenna + cable assemblies is required + put the antenna on the operator's tower
4) A modem with ports for connecting an external antenna
is required repeaters, to the router
6) If there are not enough ports on the router, you need to buy a hub
7) The router is needed with a usb port, the easiest option is zyxel keenetic, but I use asus or tp-link with a usb port and firmware openwrt / tomato
8) It is necessary to calculate the location of access points around the house. For example, you can use the router. We installed the router in the corner of the house, looked where the signal is stored, in the opposite corner we put it, we look where the signal is stored. It is necessary to cover the house with a uniform signal for 4 sticks, approximately.
9) We pull the twisted pair cable from the router to the calculated points. At the end, we set the access point, we configure the wifi network in the same way as a router. We give different IP addresses to each access point, and do not forget them.
The result - just a wifi network throughout the house, cheap and cheerful. If you need a seamless array, then this is for microtik.

Instead eval($_R);doecho $_R;

This code simply changes the $_X variable from one character to another. For confusion.
The most important thing is the value of the $_X variable. Perhaps it is taken from the input parameters. That is, it allows you to execute ANY code on your server.
