The first switching systems we're probably going to see here are
wireless cards that switch between PHS and WiFi. In this case, it's
actually enhancing traffic revenue, because the contracts are flat rate
for unlimited data. So moving a user off of PHS and on to WiFi means
that the carrier uses the (presumably cheaper) WiFi network to ship the
packets around rather than the more expensive PHS network.
(By cheaper, I'm not just referring to the costs of moving the packets
through the air, but also getting them to the Internet once they've hit
the base station. I do know of certain circumstances where this would be
a huge cost savings to the carrier, but unfortunately I can't give out
the details here of exactly why this is.)
