Using TCP/IP as the communication protocol, and "cell" hubs connected
to Internet thru cable modems/DSL connections - there is no reason
a "cell"-based system can't be made to work.

One of the biggest problems with the 2m Amateur packet systems was(and
still is) the existance of high-powered, wide-coverage "high-level"
nodes.  With one of them on a channel - it basically becomes unusable.
In the Los Angeles area; 145.01, 145.03, 145.05 are perfect examples of
this(K6VE seems to be the biggest blow-hard).  At times these "blabber-
mouths" even affect San Diego and Riverside/San Bernardino Counties.
The 2W ERP and repeater limitations actually assist the "cell"
technique - they do NOT "cripple" it.

Why not.  All most hams know how to do is argue, criticize, block
progress, and put up old-fashioned high-power jamming stations - so
that they can be king-of-the-channel.  Building functional
communication networks seems to be one their lowest priorities.

The protocol makes no difference at all. You have to build the RF part of
the network correctly before you can run ANY protocol over it!
Why this focus on using wires instead of radio? Why not connect
the cells together using radio links?

Please read past comments about cell based ham radio networks.
You need to hook the cells together, using super-cells, and hook
the super-cells together, etc. This is well-known technology, just
not used by the cell phone people (because they use wires to connect
the lowest level cells together). What you described is simply a network
topology designed by someone who has not paid attention to work
done in the ham radio networks 15 years ago. It ain't hard to build
WORKING wide area ham radio nets. But you do have to think
about how you will create small cells, and then how you will create
large cells to hook the small cells together, and then how you will
trunk those large cells together from city to city.

You mentioned only 2M frequencies.

Your solution seems to be "I don't know how to figure this out,
so I'll just punt and use the telephone company instead."
There IS much better (RF based) technology available. No, I don't
mean commercial frequencies, or anything like that. I mean reasonable
network topologies instead of the junk you described above.

Oh bull. Hams know how to build network, and have proved it in Europe,
and in some parts of the US. The "Gee, let's just use wires instead of
wireless."
folks sure make a real mess of things! Pure laziness in my view.
