Here are some more references on wireless network capacity.  These dry,
academic papers are part of the reason the CUWiN Technical Lead remains
enthusiastic for wireless networks in spite of being veryvery work-weary
at this point.

Citations for some well-known works on wireless network capacity are
at <http://www.utdallas.edu/~mxp012300/capa.html>.

As far as I am aware, the first document that sketches the
architecture of a metro-area wireless network of thousands
or millions of nodes, from bottom to top ("Layer 1" to
"Layer 3"), is the 1995 Ph.D. thesis of Timothy J. Shepard,
<http://www.lcs.mit.edu/publications/pubs/pdf/MIT-LCS-TR-670.pdf>.
A magazine article, <http://www.eet.com/story/OEG19981007S0014>, distills
what Shepard was writing and thinking about back then.  Note Shepard's
optimism about routing scalability---the magazine article pre-dates
the paper that introduced HSLS routing by only three years.  As usual,
there is nothing new under this sun: CUWiN has just been unpeeling the
same onion from the outside that Tim Shepard was unpeeling from the,
umm, inside...?

A lot of people mistakenly interpret Kumar's and others' results as
*absolute upper bounds* on wireless network capacity.  Not so!  They are
upper bounds under certain assumptions, which the papers spell out.
Nobody knows the "bit-meter/second" capacity of the radio spectrum.
David P. Reed re-emphasizes this point in spectrum discussions a lot,
