there are ways to increase the capacity wihtout the billions of spectrum auctions.

What effect will OFDMA or other directional antenna technologies have on spectrum capacity? Is OFDMA a part of any network at present?

but spectrum does not multiply the capapcity as much as spectrum reuse.

Depends.

If I am on the corner of Wall St and Broadway there is X amount of available capacity to a single user from a single operator which has deployed FDD 10Mhz , if I divide the cell into 4 smaller cells. There is still only X amount of capacity available to a singular user at the corner of Wall st and Broadway. While capacity over the entire area will have increased via frequency reuse, capacity to a single point will not increase by any large measure

However, if we double the amount of spectrum FDD 20Mhz, there is now somewhere approaching 2X the amount of available capacity to a single user at a given point, using the same air interface that is. If we are using LTE, then the capacity gains would be even higher through the doubling of spectral availability.

Here is what Qualcomm says,

"LTE, on the other hand, will be primarily driven by availability of NEW WIDER or TDD spectrum. It will be deployed as an overlay to augment data capacity of 3G networks and their evolutions.

dreamer warning...
Hardly!!

People are buying spectrum because it is a rel estate play.
Agreed, afterall... They aren't making any more of it.

But there are ways to increase the cpapcoity wihtout the billions of spectrum auctions.

Oh! I Agree. But, that will happen as spectrum valuations rise. Until then, the acquisition of spectrum is still the cheapest avenue with the advent of Software Defined Radios, etc.

If frequency reuse was the cheaper option, why bid Billions for spectrum?

I have no doubt that the large metro areas will reach spectrum deficiencies in the next 5-10 years of growth in Mobile Broadband Data Networks.

Device Manufactures will seek their own "Private Label" Networks so they are free to deploy device specific services to create device specific competitive advantages without the "permission" of "MaBell", "TBell", or VZBell"

We already saw Qualcomm effectively block EchoStar/"Frontier Wireless" from acquiring a Nationwide 6mhz footprint via the purchase of the E Block in New York, San Francisco, Los Angeles, Phily markets at Auction last year.

The Spectrum Speculators are not worried about INCREASING the capacity of existing networks, but more so for the requirements of the flood of New Private Label Mobile Data Networks that will be built in the next 10 years.

Much like Qualcomm built their own "Private Label" Network for FLO.

It's only the beginning.

And so it goes,
