OK, we do not speak about same users : you speak about population and I about emcomm teams. For sure, emcomm teams have to listen to population (I think about PMR446, LPD433, CB27, E channel…) in voice mode, but they need to build internal radio infrastructure to share information. Ribbit could be a brick of this solution :
easy to deploy
without specific hardware (compatible with what every amateur radio already has)
high density of information transmitted by spectrum used
