I don’t know what kind of idea you are getting. Radio and wi-ifi are waves. The wave is what can be used, you don’t care who generated it. To say it somehow the wave is in the air and you just take advantage of it being there to convert it to energy. Doesn’t matter what the wave could have been read as. In general a radio station is not going to stop working for a whole region just to stop you from using it.
Anything that can be powered by this research, can also be powered by a button sized battery for weeks if not not longer. I thinks its more intended for very off grid stuff but maybe im just too uncreative.
There are already lots of concepts for low power wireless communication for example LoRaWAN
The issue is not the ISP its the technology used to establish a connection between devices. We need hardware that can run with the low power requirements that come with this research.
That’s not any sort of legal issue stopping you, that’s physics. If you’re trying to create say, some sort of mesh network, and the device is using all of the signal’s power just to run itself, there’s no power left to retransmit. You don’t get something from nothing. We’re talking microamps and smaller with these devices.
If you’ve ever used a crystal radio, you can get an idea for how weakly powered stuff like this is.
Edit: look up the channel “EEVBlog” on YouTube, dude has a dozen videos on various such devices and goes into the actual math and viability of each.

Maybe i left out too much context.
Im not talking about the research itself, but about how it could be utilized.
Their idea (having small devices that can be powered by nothing but stray radiowaves) apparently works and is great by itself.
However its usefullness is limited if you cant somehow connect those devices with the rest of the world. Thats the issue im complaining about.
There are tons of small devices that don’t have to be connected to be useful. Lots of personal items or small sensors.

I just want it for my TV remote if the form factor is small enough
Good news, that was invented in 1956: https://www.theverge.com/23810061/zenith-space-command-remote-control-button-of-the-month
That’s actually really neat!
What are you asking for here? Some sort of worldwide free ISP?
