Nope, sorry. You had confused WiFi with femtocells, and that's what I rejected.
Obviously, converting all cellular voice to VoIP can help make better use of
the existing 3G networks, with or without WiFi. If the cellcos would cease all
of their 2G service, as they ceased all of their AMPS service in 2008, they
could eke out more efficiency from their available spectrum. Mainly because
circuit-switched voice has now become a smaller fraction of cellular usage than
data. Much the same as what happened to the major cabled trunk lines, years ago
now.
And by the way, no need to buy into the LTE hype for this. Cellcos can convert
their 3G service to all VoIP as well.

That's wrong. The spectrum grab from the TV broadcasters wouldn't even solve it
for that long, and those TV frequencies are ill suited for congested area
two-comms ANYWAY. For tiny cell areas, you certainly don't want to use lower
UHF frequencies. And tiny cell coverage areas are what you MUST have solve the
wireless spectrum crunch WHERE IT ACTUALLY EXISTS.
