At this time, femtocells require an FCC license. The governmint wants
to treat them a extension of the cellular provider and are therefore
required to provide interception (wire tap) services. The providers
seem to think that the femtocell will also provide access for their
other customers as they pass by. That's fine, but since the backhaul
will be via the internet, the home owners broadband might become
seriously constipated if overused. There are also topology problems
as the current cellular architecture is not going to scale to huge
numbers of home femtocells. Lastly, I'm not sure the average home
owner is going to give up their free cordless phone in favor of a
billable cell phone equivalent. Incidentally, the old AT&T tried this
with LMDS and an ISDN backhaul on the pole many years ago, and gave
up. The issue was not lack of speed. It was customers balking at
paying for in the home phone calls.

So, what comes after femto? Well, there's atto, zepto, and yocto (in
that order). I guess the AttoCell will be a wearable cell site and
ZeptoCell will be where the cell site is implanted in your head.
