Spectrum Allocation chart from the article

Is there someplace we could download a visible copy of the Spectrum Allocation chart in this article, or is that something proprietary and not to be downloaded? I tried saving a copy and printing it but the details were not visible (it was too small). Thanks.
For like $15 shipped you can get a HEEEEEEEEEUUUUUGE wall-chart (glossy too, WOO!) for your geekhaüs wall from the US GPO....

Cingular Wimax

There are strong rumors that next year Cingular will roll out Wimax services. One of the first will be New York
Are you sure someone didn't confuse Cingular with Comcast? πŸ˜•
I don't think anyone has announced WiMAX equipment for the AWS band. I'm not even sure the FCC rules for AWS would accomodate WiMAX (although I could be wrong.)
thats sprint.
.... and when that system falls on its butt, maybe people will realize what a bunch of garbage the Wimax standard is to begin with.

Why no Alltel 🀨 ? They seemed to me to be one of the biggest players as far as non national providers. And yet no AWS purchases? Not even a newly created small company to help them buy it cheaper. To me that looks like they don't want to spend any of the companies revenue on spectrum possibly to maintain current company value? Perhaps Verizon is plaaning on buying more than just spectrum. Wink Wink πŸ˜‰ Seeing as how they are already one of Verizon's biggest roaming partners that would explain them being absent from the auction. Verizon's goal seems aim at being the spectrum king.
I think actually Alltel did do some purchasing but under a different name.

So is that why...

In other words - in the chart above - phones "listen" on the blue bands, and "talk" on the green bands. Vice-versa for towers (which in industry lingo are called "base stations".)


I am talking to someone on my phone on the 850 band when static starts to come in the listening end, yet when I speak the other party hears me fine.

Is that because my voice is being transmitted in the lower half of 850, therefore able to punch through buildings and go further, but the tower signal, coming on the top half of 850 can't quite connect as well?

Am I putting 2 and 2 together properly, or does the difference of 5-10 MHz not matter nearly that much?
The difference is actually closer to 50 MHz, but that's still not very significant when it comes to how well the signal penetrates walls, etc.

I think it's more just that the send and receive bands are separate, so if there's interference or someth...

T-Mobile Spectrum?

Great article, although it does raise one question for me. In the article, you claim that the AWS spectrum, as well as the spectrum T-Mobile bought, corresponds to the UMTS bands used in Europe (at least the 2100 part), which will make it easy for existing 3G phones to work on AWS spectrum. The quote from the article is: "The upper part does line up perfectly with Europe's UMTS 2100 band, and the lower part does line up with Europe's DCS band. Therefore manufacturers already building GSM+WCDMA "world phones" actually won't have to support any additional frequency bands at all."

In T-Mobile's recent 3G announcement, they claim the AWS spectrum they bought is unfortunately "a few megahertz off from the UMTS 2100 used elsewhere, meaning exis...
Because, as this article says and the chart shows, the lower half (the half used for phone-to-tower) is completely different. It lines up with DCS, but not UMTS 2100.

"a few megahertz off from the UMTS 2100 used elsewhere" isn't really accurate. Th...
...so was that really not clear from the article alone? ...because that's pretty much the single most important thing I was trying to explain by writing this article. I hoped the second chart on this page would explain it:

Here is the deal. it is'nt what T-Mo got it is what they are going to do with what they now have. As most people know T-Mo does not give a HOOT about watching TV and VIDEOS on your phone ( we have enough accidents with people talking on the things ) T...
I know you just clarified it in like 2 or 3 different ways, and i do understand the different reasons... but will his E61 never pick up even that second half of AWS that does in fact line up?

So, i guess what im asking is it ALL OF BOTH OR NOTHING...
One of my original strategies with this article was to rely on graphics to explain some of the more complex issues, but your feedback helped me realize that the major points need to be explained in detail in the text as well, so you know what to look ...

SUPER article. Thanks Phonescoop!

Thanks for breaking these new spectrum details down for us. Very informative.
Thanks! πŸ™‚
Agreed! Great job Rich and Eric!
Awesome article. It is nice to now understand how spectrum works and why it is so important. Thanks Rich Brome! 😁
Great article, THANK YOU!
Hear, hear! Excellent write up. You break it down clearly and efficiently. Thanks.

Will VZW expand into new areas now?

With the Verizon Wireless license in all of the eastern U.S., will VZW expand into new areas where Alltel already operates, to help competition with Cingular in some markets?

If so, this would be a great advantage to many people, including more choices for consumers.

Cricket and UScellular "just playing by the rules"

First off, VERY informative article.

anywho, wasn't the FCC trying to discourage this by getting rid of blind bidding? Barat and that other co. just seem like corporate puppets.
Blind bidding, designated entities... yes, it's all very controversial, for obvious reasons.

Yes, the FCC did try reduce the amount of such shenanigans in this auction, and it is in fact much better than some previous auctions.

Without being an ...

AWS causing mergers?

Any word or thoughts on a possible merger btwn Cricket and MetroPCS? they offer the same type of service and i think they are affiliated in some way. if they merged they might be able to offer some better competition to the already established "big boys."
