In my opinion for best mesh network the lora module must be small and offgrid.
For example, typical module:
- small device with solar panel to install outside.
- small module to put(integrate) with routers (similar Cellular modem or ethernet device)
- small module with screen and some keys similar pygo.
In any way in my opinion popcorn MUST have a removable antena for lora. Some people can using integrated, some will using big for car or outside home.
