By supporting networking (and also using a mesh to increase range).
As I understand "walkie talkie" radios, the spectrum they use (GMRS/FRS/CB/MURS, etc) isn't permitted to transmit data in a way that's useful for proper data networking (there's some allowance for data but not really anything like what most people think of as networking, and encryption is right out of the question).
For the most part, these radio specs can only increase range by use of repeaters. IIRC meshtastic takes a mesh approach to increasing range and reliability.
