Organize a WiFi network over a long distance

Question

Computer networks

I need to create a WiFi network with a neighbor at a distance of 450 meters. (Visibility is almost direct, a couple of trees interfere a little)

I read the Internet, where craftsmen create networks of 15 km. The main method is 2 antennas directed at each other.

1. Will routers help at 800 meters (I saw such from Asus)? Or is the antenna better?

2. Which antenna will be optimal in quality (taking into account the trees - more powerful)?
I'm going to make my own antenna. It is necessary to minimize costs.

3. Explain the layout of the equipment.
The neighbor has an ADSL connection (via a telephone wire, if I'm not mistaken). What equipment should be supplied to him, what to me?

As I understand it, you need to: Put a regular router on your neighbor, attach an antenna to the router in some way (?), Directed at me. What should I attach my antenna to if I have 2 computers without Wi-Fi? (card to computer or another router for me?)

Diagrams and instructions are welcome.
Thank you!

Answer 1

A similar task, but the distance is 1.5 km. On the one hand, the Asus 500 access point and the ANT24-1201 antenna, on the other hand, the noname USB card on the 8187L and the ANT24-1201 antenna. Trees on the way.
Everything has been working great for over 2 years now.

Answer 2

You do this, just do not forget that at the same time you are formally violating if there is no radio network registration. You have to pay for outdoor wi-fi. And he needs documents.

Answer 3

As I understand it, you need the Internet from a neighbor, therefore, he must have a router, but a Wi-Fi network card is enough for you. It is necessary to make 2 antennas of the "double square" type and point at each other. I don’t know about 800 meters, but at 450 everything will definitely work with little signal loss.

And, of course, don't forget about the box of Pringles chips for the antenna :)

Answer 5

I recommend looking in the direction of special solutions. For example, Ubiquiti NanoStation.

Answer 6

Put two long access points , buy two directional antennas , mount everything, point the antennas at each other, make one point in AP mode, the second in client mode cling to the first.
You stick both points into the switches at both points, voila everything works.
Physically, such a dotted circuit will look like just a regular ethernet cable for switches.

Answer 8

I don't recommend the can. In it, the receive circuit is open and can accumulate static, which is not good for a router or card.
Maximum range with minimum effort can be obtained with a helical antenna .
Biquadrat is done in a couple of hours, or even less, but less directed. If you stop at it, I advise you not to use the U connector as a basis. It is better to solder directly to the cable passed through the tube.
And another very important point! The cable length from the antenna to the equipment is very critical. If access within 10-15 m is not possible, you can consider the option of installing an access point or router outdoors right next to the antenna.
Good luck!

Answer 9

If you are not urgent, wait until the new IEEE 802.22 standard is available
They promise a distance of up to 100 kilometers
