I had a couple people challenge me in recent days on my spectrum deficit post, saying that femtocells should take care of this . . . right?
Femtocells do a couple of things for long-term evolution (LTE), an effort to develop advanced wireless mobile radio technology that will succeed current 3G WCDMA / HSDPA / HSUPA technology.

So here's what femtocells do.
1) They improve signal strength where it's marginal - inside
buildings in particular.
2) In the end game, the idea is to cut up relatively large areas
covered by a single basestation and subdivide it into more femtocells,
meaning fewer users per femtocell and more available opportunity for
each user to connect.
But here's what femtocells don't do:
1) They don't provide more spectrum.
2) They don't increase spectral efficiency. That's determined by the
encoding.
