Voice traffic is not the major problem,

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?

The underlying philosophy is the same - move the mobile traffic to a
wired network when possible.

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.

Yes Bert. You are ignoring the point. Smartphones ALREADY use WiFi

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.

EXACTLY, but only in areas where their low power levels exceed the
levels of the signals from the cell towers.

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.

You can only push spectral re-use so far. At some point you need more
frequencies to handle more traffic.

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.
