How to organize your own radio communication channel for 70 km?

Question

WiFi

Good afternoon!
I have a need to organize my own radio communication channel between two settlements. I hope for communication quality comparable to speeds up to 100 Mbps.
Please tell us how realistic this is, what technologies need to be used, what money may be required (assuming that there are no mountains between the points and it is possible to create a channel directly) and how legal it is.
Thank you!

Answer 1

Look at toys of this kind are expensive, you need permission for a technolink, but there is nothing unrealistic, and there will be decent delays in online toys. In general, the ideal option is optics, but the gasket and all permits will cost several times more than the radio channel.

Answer 2

I absolutely support the decision on ubiquiti at the moment 2 bridges have been announced for 2.4, 5 and wow 24 GHz. Bandwidth for documents up to 1-1.3 GB. But the piece of iron is not the worst.
And now the most interesting.
Equipment of this class must be registered at the Radio Frequency Center. Every region has one. You provide documentation for the equipment there, tell where exactly your equipment will be located, because there is a link to the address or coordinates, and the commission is considering whether to give you frequencies or not. Refuse at times even to providers, but the attempt is not torture.
The main thing is to get permission first - then buy equipment.
Get permission - put the equipment and rejoice. It is also very important to take measurements on the ground before you buy - there may be a drop in speed for various reasons.
In any case, the local Radio Frequency Center will advise you best. This is their job.

There is also an option with satellite internet. Now it seems that outgoing traffic is not so expensive. And there are laser lines if there is a direct line of sight. But I'm afraid you can't do without intermediaries for a tower for 70 km)
