thoughts on "ideal"

["tim clifford" <tjc@lacunanet.net>]

there are a few places where the requirements draft points to some "ideal"
case, it seems prior to some justification.

for example
"The ideal IP access infrastructure is one where the RAN is an IP network
where
base stations, base station controllers, and mobile terminals communicate
via IP
protocols. "

I would stop far short of calling this ideal; similar initiatives in the DSL
environment decided upon an ATM/l2tp access infrastructure; in general the
access networks for internet services seem to be layer 2.  So I can
understand that IP in the RAN is an interesting and may yet to be proven
ideal, but i'd be happier with a requirements draft that doesn't make these
judgements.  maybe its a candidate?

outside of the MWIF technical reports has anyone seen a justification for IP
in radio networks as proposed.
