I find it crazy how govs around the world just have and sell the licenses for the whole spectrum...

Thanks to microwaves, the "junk band" of 2,4Ghz and 5Ghz are "free"

And we also have a spectrum around

60Ghz

so we just use that?

And are able to get 1Gbit/s on over 2,8km distance !

But I'm still more interested in LoRaWAN

While LoRaWAN has its good sides, it also has its bad sides..:

And be very careful, even RAM in your airgapped PC (which has no bluetooth or wifi) can be used as antennas ! They call it AIR-FI instead of Wi-Fi

And 3 letter agencies probably already researching how to get your private data.

Don't believe? Here:

AIR-FI - Academics turn RAM into Wi-Fi cards to steal data from air-gapped systems

and:

NSA TEMPEST Attack can remotely view your computer and cell phone screen using radio waves!

Especially if they made the hardware or play a part in making it, they will find a way to create a backdoor to access one's private data, collect it and in some ways, use it against the person. AIR-Fi, is new to me but it seems the range could be wider than Wi-Fi.
