All of these radios can operate on unlicensed wireless spectrum. So the radios are cheap and the spectrum is free. When you consider that buying cellular licenses to cover the US would cost billions of dollars, that’s a pretty big deal.
It means that anyone can deploy an LPWAN network, no license required. With a couple of gateways, you can build your very own network to cover a corporate campus or basement or farm where cellular doesn’t reach, and run thousands of devices on it.
