I would like to see how you would install a few km of optical fiber, especially not in your property.

I would like to see how you would install a few km radio-link for high speed data transfer with custom protocol and with no license and no payment for the frequency band...  :)
You don't need anything custom  |O. Just wifi with good directional antennas. And if you need it faster and more reliable, there are solutions made specially for that, although way more expensive https://www.saftehnika.com/en/integrae.

the same issue with radio link. For example, when you use WiFi, other WiFi routers make iterference and leads to connection break.
Not the same at all. The main problem (alignment) I mentioned already makes it a no-go. Others are just an addition. With directional antennas, interference is not such a big deal for wifi, especially in rural areas. Again, get a special solution as said above. https://www.saftehnika.com/files/downloads/367eec22-af4c-e911-8f79-0050569a8c0f/Integra-E%20distance%20graphics%202019%20in%20MILES.pdf

Cryptocurrency has taught me to love math and at the same time be baffled by it.

I wonder why nobody though of building wireless internet connections using vector signal generators paired with vector signal analyzers?  :popcorn:

There are different versions of it, say 2,4 GHz, if you cannot use 900 MHz.

That's their version of LTE-U, the U for unlicensed.

What did you mean? For LTE you have to buy a Licence for a Time Period.

Note that the Ubiquiti unit does not implement actual LTE-U but rather a proprietary version of it that works in a similar manner. Would be interesting to see a teardown but I suspect it's just a LTE radio with some custom programming.

Nope a Transmitter who work on a ISM Band must be from the Manufacture declared to be in the Specification. The same for CB Radio and PMR446 Radios.  :-+

What do you mean by "from the Manufacture declared to be in the Specification" ?

I am not particularly familiar with how the laws which regulate ISM bands work outside of the US but I do believe they are similar to the US. You can use the ISM bands for anything you want as long as you stay within certain power/eirp limits. See FCC Part 15, sections 107, 109, 205, 207, 209, 247, 249. Stuff like microwave ovens, inductive heaters, and even RF exciters for gas lamps use these frequencies as well. These bands are not licensed for Wifi, they are specifically unlicensed.

Here in Europe the Manufacture must declare that the Product is Law confirm.
For example: https://www.alan-electronics.de/alan/CustomUpload/374O357O340O370O356O369O350O320O363O352O365O/AE6110_CE_Declaration.pdf
If your Product dont have anything lile that you are not Permit to turn on.

Ah ok, then I would assume you could say it complies with the EU version of those same/similar FCC rules.

The Company must declare it conformity. You cant build your own stuff (beside of pro certificate Stuff) and use it without an external Certification.

So could you perhaps build something using an off the shelf RF module of some sort as long as that module is certified?

You want built your own 868Mhz Thermometer you can use a Module who is certified and you get a written conformity declaration.  :-+
Sure you cant modify anything like a Antenna with more gain.
