FCC Chief: "We Face a Spectrum Gap" Due to iPhone
According to the U.S. Federal Communications Commission chairman, the rapid growth in bandwidth usage by mobile devices like the iPhone threatens to overload the available electromagnetic communications frequencies - or "spectrum," as the FCC refers to it - allocated to such devices. As a result, creative new policies will have to be implemented to avoid a "spectrum gap," the chairman said.
In a Q&A with Business Week, FCC chair Julius Genachowski said that if current trends continue, there will not be enough spectrum available for the growth in mobile broadband access. This growth is largely attributed to the iPhone and its much-discussed Hummer-like thirst for bandwidth. Familiar complaints about AT&T's US 3G service - network overloads that result in dropped calls, missed text messages, delayed voicemail, slow downloads, etc. - will become increasingly common, even if Apple allows other service providers to carry the iPhone, because the carriers have nowhere to go to build out their infrastructure. To deal with this, Genachowski said, the FCC will have come up with new ways to allocate the finite amount of spectrum available for wireless services:
"We've been spending time on long-term spectrum policy because the data suggest we face a spectrum gap. The demands that are being created by the iPhone and other mobile broadband technologies threaten to outstrip the amount of spectrum available for commercial mobile, and it's important for the country that we get long-term planning right because it takes time to identify spectrum and put it on the market. We're looking at potential innovations in spectrum policy, such as secondary licensing for spectrum, and other, more creative ideas for unlicensed spectrum."
3G iPhones currently operate in either the 800-MHz (IS-54) or 1900-MHz (IS-136) frequency bands. In many markets, all available channels are either at or near capacity.

Wasn't this the reason that over the air television was killed? To open up more room or cellphone companies?
Supposed to read "more room for". Gotta love typing on the iPhone

I thought they were sold to phone companies. I am gonna do some googling.
Analog spectrum boosts AT&T (T) and Verizon (VZ) -- GuruFocus.com
Apparently Verizon and AT&T bought a couple of dollars worth of it.

That made sense. Now force At&T to work.

I don't think Att are rolling out that spectrum until 2012

ALL-DIGITAL TELEVISION IS COMING (AND SOONER THAN YOU THINK!)). I guess the phone companies are getting a piece of the pie too! Maybe then AT&T will allow tethering for free...(or maybe not )

It's hard to see cause it's so small. I happen to have a large one sitting in the cubicle next to me. It's a Radio Frequency Allocation chart for the USA. Basically who/what broadcasts at what frequency.

hmmm ok is a normal human supposed to understand that graph?

the spectrum that at&t / Verizon bought from the analog TV transition was in the 700mhz. the 700mhz bands are going to be used for LTE by verizon/at&t ( most likely they will be roaming partners for LTE). the 700mhz band will be great because it can travel further and penetrate walls/buildings better than 850mhz/1900mhz.
however, these problems are very serious, as much as people want to bash at&t for the problems their network has, no other network has the same amount of 3G users as at&t. to put it in perspective see below:
in Q2 2009 t-mobile had 2.1 million users on their 3G network ( G1,mytouch 3G sidekick 3G ect)
as of Q3 2009 at&t has about 35million people on their 3G network and 12-13 million are iphone users ( the hummer of smartphones).

i just googled the graph. you can enlarge it in your browser w/o any artifacts to see every detail. very interesting stuff. i think im gonna blow it up and print for my own geeky use.killall Terminal
