You don't understand, Craig. No one focused on voice. Why do you even mention
voice? The bandwidth crunch is clearly videos and graphics to smartphones, not
voice. So?

All cell traffic comes from a wired network. Or at the very least, in some
cases, fixed microwave links. That's how cell telephony scales. That's the
whole point of cellular. You are again making a distinction when there is no
difference.

And they will continue to. The best way to fix the problem is to leverage as
much as possible on a network that has no immediate bandwidth obstacles.
Whether it's WiFi or whether it's femtocells, or a combination.

Come now. That's circular reasoning. The size of cells is always a variable the
cellcos design to. They can deploy femtocells wherever they want, and of course
the power of the adjacent cell towers becomes a factor. Even at the very start
of the femtocells movement, knowledgeable people were making the case that
femtocells were not JUST for individual households or businesses.

Let's put it this way. Increased spectrum reuse, for two-way comms, will go a
LOT further to solve the problem than a mere four additional LTE bands. And
those mere four LTE bands will gut FOTA TV in a big way.
