Where some of the "Wimax is not 4G" confusion comes from
As such, Wimax is technically a 2G evolution from Wifi.
The fact that it's being implemented onto mobile phones and not just mobile Internet cards and wireless WAN/LANs is what throws some people off. But if we accept this confusion, we also should start referring to phones with Wifi as being capable of 1G technology and/or speeds, too.
Where LTE ma...

So why do people, possibly yourself, refer to AT&T's network as being over crowded, rather than make a more technologicly correct statement and say that AT&T needs to be more efficient with the spectrum they already have.
Because it is true that AT&T has lots of spectrum, they even used something like 30mhz worth during that SXSW conference recently in Austin, Tx. So they have spectrum, plenty of it, they just don't use it. Cause they are cheap bytches.
So what do you think? Overcrowded network? Or inefficient use of spectrum?
The only thing off the top of my head is efficiency. The FCC originally set up spectrum to be as efficient as possible, but technology differences use that capacity differently.
I need something to start from.
Interestingly, de la Vega (the CEO of AT&T) spoke about the critical need to increase available spectrum in the US, just barely in March at CTIA.

What I gathered from the whole thing (which I've seen parts of before) was that there are other methods and other technologies that could be implemented to hold off a massive increase in demand for spectrum use in the coming decades. As I understand his perspective, all wireless telephony technology is inefficient, not just a specific carrier. That's right, CDMA, GSM - even Wimax and LTE - are spectrum hogs that could be made more efficient. Also, st...

Because of Cooper and his invention of the portable cellular phone, more than a few people started using it. the 250 MHz of spectrum was estimated to be more than enough for some time, just like any technological folly (no one would need more than 10 megs of hard drive space, no one would ever b...

All I care about is how to sell *MY* phones and how to bad mouth the competition.
If I sell Sprint... WiMax is most definitely 4G. Why? Because 4G > 3G.
If I don't sell Sprint... WiMax is most definitely *NOT* 4G... because how can I sell the newest, best phones - if they are on that other company.
Guess that means I'm on the side that wants to sell phones... to heck with technicalities and techno mumbo jumbo.
Granted...
I sell *BOTH* sets of phones so... 4G is whatever the customer needs to hear at that moment.
Either it's the greatest thing since sliced bread... and yet another reason why Sprint is the best company since dawn ...

There are a number of standards to meet what the agency considers 4G, wimax and lte in their current forms conform to most of the standards but not all and thus are not truly 4G by the agencies definition of such.
ITU considers 4G to be any mobile telephony system which can transfer data at a rate of 100 Mbit/s. This is their definition, and may not be the same criteria as other organizations and government agencies.
LTE is said to have a theoretical capacity to be transmit at these speeds, thereby being considered a 4G tech by the ITU, but because LTE is an emerging technology this capacity has not been realized yet.
So, by the ITU, LTE is NOT 4G, but by most everyone else, LTE IS 4G based on the untested physics pertaining to the technology.
In fact, the ITU considers CDMA2000, EDGE, and WCDMA to all be 3G technologies, despite other organizations, commercial interests, and th...

In some ways it's similar to companies that make speakers listing the peak power on their products and not the RMS. (reccemmended manufacturer setting)
Or camera companies acting like megapixels are the sole determiner of the quality of a camera like it has nothing to do with the quality of the lens or optical sensor.
Or like megahertz is the sole indicator of the speed of a processor. the list goes on and on.
From a sales standpoint 4G sounds much more marketable than 3.9 G, or almost 4G.
So in some sense companies have jumped the gun in a desi...

As this point, let's call it what we're calling it already and move on. We can better define all this once we start looking at 5G.
