This is exactly why I have never bought into the Genachowski FCC
alarmism about spectrum, and their single-minded resolve to grab
everyone else's spectrum for mobile wireless. That approach simply
has no future. It doesn't scale. This approach, instead, leverages
off the cabled infrastructure to make a real difference, just as
cellular made initially, compared with longer range two-way radio
telephony.
Parenthetically, femtocells don't need LTE to work. More unnecessary LTE hype.

Sorry Bert, but many of the benefits of off-loading traffic from the
wireless telco networks have already been realized. Femtpcells are
certainly part of the long term solution, but they are not going to
resolve the need for more spectrum for mobile connectivity.
When I am at home and work (or in the hotel where I am currently
staying) my cellphone ALREADY uses WiFi for data. Off-loading voice
traffic can help a bit, but VOICE traffic is not the problem. The
MAIN benefit of using femtocells for voice is improving the quality
of service, which sucks in the metal warehouse I work in. And MANY
corporations have already installed femtocells to take care of the
workers in their buildings.
If every landline in the U.S. were replaced with a femtocell we would
still have a spectrum problem. And femtocells are not a viable
alternative to LTE, because their range is so limited. They do a good
job for what they are intended, but are not a viable alternative to
higher powered cellular networks when you are mobile. In plain
English, if you are in a fixed location they can help, if you are
moving around you need a network with more power and the ability to
hand-off your transactions to other cells.
Before you chime in that you can create networks of femtocells,
remember, they use spectrum too.
