Very similar to the CC1200 I used in a radio I designed in 2013:

Low data rate networks are super interesting. The long range let’s you do things you wouldn’t do with WiFi. But what i would really like is a high bandwidth long range mesh. The issue you run in to is who owns the spectrum. In the US it’s private communications companies that buy large chunks of spectrum. I’d like to see more valuable spectrum allotted for public use. This would pave the way for free or very low cost municipal cell phone service. Unfortunately there is big money interested in making sure that doesn’t happen. And with “business friendly” people in the FCC, the idea of free communications doesn’t have much traction.
This radio project looks cool. Ideally we’d have a generic 915mhz radio in our cell phones. I guess since this device also has WiFi, you could connect a phone pretty easily. Let’s beg the Librem folks to add a sub-Gigabertz radio (915/868/433MHz) to their next phone. :-D
