Its an interesting idea. I looked into it a bit ago where it applied to smart cars.
Being in the mid 800 meg range gives it good penetration but very line of sight with no bouncing around hills. I run a mesh system similar to it for my home network. Some Ham radios have a feature where you can link (forgot name, someone will chime in) showing you gps of your friends. It works like a mesh system connecting through others. I'm capable of it but none of my friends are so, I don't use it.
LoRa (Long Range) gets its name from its ability to connect and hop station to station, giving it range. As a stand alone system trying to go long range point to point its power falls short. I believe the output is in low milliwatt or high microwatt. In a city it could work with your cell phone connecting to everyone else's cell and hop its way to a tower. No more one bar signal in some areas of the city (my house).
The technology actually rocks where it would apply to smart items. The idea is to have smart cities. Everything connected to everything including smart cars. Imagine the car being able to communicate with other vehicles to avoid collision. Wifi would be everywhere. Your fridge would communicate with the stores and have items delivered as needed (that's sort of here now). It would be (kind of) city wide wifi.
