I believe the constraint on such a deployment would be having enough
free channels to allow simultaneous access to enough of those people.
As there is only a set amount of spectrum for 3G, it can only
accommodate so many concurrent users per base station. You cannot
build another base station next door as there is too much overlap
between the channels. I understand even with a code division protocol
there are pretty low ceilings on how many concurrent users can operate
in a given geographic area.
I'd love one of the more radio savvy LINKers to fill this in with
examples or figures.
