Well, in most places where there is a problem, a SINGLE digi
can already hear all 60 stations in the fully saturated network
and there is nothing simpler than a single digi!. Adding a an
additional layer-3 to the protocol only adds more overhead and
QRM to an already saturated channel..

And their communication range is only a 1/4 mile!
I dont see any comparison...
Again, the only solution in saturated areas is smaller cell sizes.
