Wi-Fi bridge for 20 km

Hello, dear inhabitants of Habrahabr!
I have such a problem — you want to build a stable Wi-Fi bridge for 20km. It is planned to use a pair of NanoBridge M5 Ubiquitu.
The signal path is 7km around the city, the remaining 13km in the fields. Ripened some questions:

1) As I understand it the two routers the same, they are directly connected, twisted pair, or bridge of the two NanoBridge?
2) How much on average will increase ping?
3) What can be the pitfalls?
4) Where to put the set in case of failure? :)

I read similar questions, and one of them was advised to use this service. Here is a screenshot:


In any case, the manufacturer's Website, Yandex.Market

1. For networking equipment it looks like a piece of cable. I have "client" side access Point bridge — switch — access point for distribution. Working fine.
2. Can be from a few milliseconds to a couple hundred and up. Depends on the settings of the signal level, the workload and the weather. Therefore, it is better to disable for bridge broadcast packets.
3. NanoStation may not be enough, besides the continuous antenna windage big — maybe a strong wind to collapse. Better to take the AirGrid or bullet combined with segmental-parabolic antennas stronger.
4 Know tell me :) In future I want to change its bridge, but what to do with the iron present.

What's the frequency? 2.4 GHz bridge a maximum of 2-3 kilometers and the speed will be low...
5GHz supported, which can interfere with the use of this frequency?
At the office. site: "capable of 100+Mbps real outdoor throughput and up to 30km+ range" - Patricia9 commented on October 8th 19 at 03:20

We should not think that this is all at the same time. Speed 100 Mbit or a distance of 30 km. - Sherwood_Larson commented on October 8th 19 at 03:23
Yes, I understand. I have enough 30Mbps at 20km - Patricia9 commented on October 8th 19 at 03:26
I looked at your antonci, it will be possible to calculate. As with the 7km in the city, populated by skyscrapers or the private sector? The picture on the left shows the area is not clear...

Ocelot, there is still AND, but most likely marketing zamanuha - reuben_Pacocha commented on October 8th 19 at 03:29
The first antenna was on the roof of 10-storey building. I counted 10 houses above mine, which might be interference. I can give exact coordinates if it can help. - Patricia9 commented on October 8th 19 at 03:32

Maybe I don't understand something, but in the city from the roof of your antenna such power may remove organs and take.
The chance that out of the thousands of satellite dishes on the roofs of the city they will notice my + its relative cheapness allows me not to worry so much for her fate. - Patricia9 commented on October 8th 19 at 03:22
It's all nonsense, no one knows what kind of antenna and just will not touch.
Can as a variant to make the castle in the attic and everywhere write that the key in sq %user_flat_number#. - Sherwood_Larson commented on October 8th 19 at 03:25
My roof is corny fenced TSZH two iron doors, I'll have to come up with a story about the reason that made me go on the roof... by the Way, what could be the reason? - Patricia9 commented on October 8th 19 at 03:28
There is one way: buy(or take from friends) working suit(as the installers, if it is a logo of some ISP's that do fine), go to the attendant to EA and say that you need to check the trunk connection(not to split hairs, better than phone). Always work
— Option 2: be honest to come and say what you want to put the satellite dish.
— Var.3: to cut locks homeowners to put their and say someone cut them down, and I put the new and have brought you the keys. - reuben_Pacocha commented on October 8th 19 at 03:31
Else you can hint that you will keep track of your roof and attic, then you too and say thank you. - Patricia9 commented on October 8th 19 at 03:34
