There aren't many radios in the higher frequency bands that can be used for networking. That is why people repurpose existing hardware.
BTW, amateurs are limited in what they can use radio for. Replacing existing communication systems is not allowed, efffectively meaning that can't have non-ham users. The systems I know about are for ham-only communication, like linking repeater sites.
