[LINK] Even Though the Evidence is that LTE Spectrum Doesn't Work....

ACMA announces:

27 May 2011

ACMA moves ahead with auction of spectrum in 
the 700 MHz (digital dividend) and 2.5 GHz 
Bands...

This should be returned to the people. Proprietary technologies don't
work when in the hands of just a few "wealthy for now" carriers.

The empirical evidence that it doesn't work has to be the results of the
recent AT&T tests.

AT&T's LTE 4G speeds could blow away Verizon

The battle for 4G dominance is ramping up this year, and it looks like
AT&T may have a heck of a contender with its LTE 4G network.

AT&T showed off its LTE 4G network performing wicked fast with 28.87
megabits per second downloads and 10.4 Mbps uploads in a supposed "real
world" scenario, reports GigaOm, which got an exclusive look at the
network this week at AT&T's Foundry innovation space in Texas.

In comparison, Verizon advertises download speeds between 5 Mbps and 12
Mbps, and upload speeds of around 5 Mbps, for its LTE 4G network.

The test was run using a MIMO antenna together with the 700 megahertz
swath of spectrum the company bought at auction, and the Advanced
Wireless Services (AWS) spectrum it already owns. Purchasing T-Mobile
would give AT&T an extra bounty of AWS spectrum, which would make
rolling out its LTE 4G network even easier.

Realistically, AT&T's 4G speeds will certainly drop when it's shared on
a cellular tower, but it'll be interesting to see if the company can
still remain faster than Verizon. AT&T said previously that it expects
to launch its LTE 4G network in the middle of this year, which still
gives Verizon a half-year head start since it launched its 4G network
last December ./Quote
==========================================

Koltai Calculations:

But it took them 800 MHz, (In Telstra and ACMA Speak that equals 46.6
cell towers.) 
@ 6MB per MHz, that means that "Real world equals" 188 users. 
Spectrum Reuse is LTE MIMO 4x4.

On one Tower, that would require 54 antenas....

Let's face it, the mobile Carriers are dead, they just havent realised
it yet....

And neither has out Government that believe that if they keep selling
spectrum to the carriers the people will be satiated.

There is not enough spectrum to provide Broadband to everyone in
Australia.
