Can someone explain what cingular is doing in regards to merging with AT&T? Are they going to shrink their 1900 band and expand their 850 one?
The reason i'm asking is i saw a deal for a nokia 7610 for only 200 bucks. I would have to sign with t-mobile for one year, but the phone does not use 850, only 1900. I would hate to be stuck with only one carrier, especially since t-mobile is pretty small.

1900mhz is in use just about everywhere in an urban setting...850 is slowly being changed over to 1900 transmitters...will probabaly take a while tho...

Elmo, where'd you get your information (about 850 being "converted" to 1900)? My understanding has always been that the 850 is the most valuable spectrum as it goes further distance (read: costs less as the carriers don't have to deploy as much infrastructure). Maybe you were thinking of Nextel who is in the process of doing a spectrum swap from the 800 mhz they own (not 850) which is conflicting with public services (police, fire, etc.) to 1900?
As I've said in earlier posts, T-Mobile is a 1900 carrier (they own no 850 spectrum). All but a couple of their devices only support 1900 in N.A. If you want to see the difference between 1900 only and 1900 + 850, compare Cingular's coverage map to T-Mobile's. The spider web-like design of T-mo's map will show the major urban areas covered + highways. If you need to use your device outside of that, better make sure it has 850.
As to the post about combining networks, my "inside" source said the midwest will convert to all 310-410 (i.e., no more 310-380 x-ATT) in June. Evidently they're having difficulty with some of the "legacy handsets" (though he didn't say who's).
Once that happens, and all the (Orange and Blue) infrastructure is tied together, the network should be unbeatable. In Chicago for example, the combined entity will have 65mhz. 25mhz 850 (Orange) + 40mhz 1900 (30 Blue + 10 xNextwave purchased by Cingular last year).
Hang in there - won't be long...

I'm a care rep...
the data rate for 1900 mhz is better than the 850... the "conversion" will take quite some time...several years... and you are quite correct 850 does propogate better over distance than 1900 but with the ATT acquistion cingular got their towers and spectrum as well ergo the coverage lapse is not a factor..... the word I got was to standardize equipment and cut maitenance costs...
btw 800 mhz and 850 in north america mean the same thing
the textbook definition....
800 megahertz 800 MHz The radio frequency range originally allotted by the Federal Communications Commission (FCC) to the cellular industry. Also known as 850 MHz.

As i understand 850 is slower then 1900 but it's wil;l travel far as i called penetartion. Tha is why where i'm at surounded by moutain and a snowy state the house and building have basement Tmobile have a tought time with reception and drop call due to 1900 used only

propagate : The transmission of a signal, (sound or RF) through a medium
whether its cement or air ...it propagates..just better thru others than some

Yes, Elmo - I've seen in GSM literature where 800 and 850 are used interchangeably. Just to level-set everyone's knowledge - the "Cellular" band licensed by the FCC comprises 824 - 849 MHz to send information from the hanset to the tower, and 869 - 894 MHz for the other direction.
Nextel specific is currently deployed in the 806-821 and 851-866mhz (SMR in FCC speak). This is what I was referring to as 800 spectrum. How do you differentiate them? They are separate licenses...
Here's a good article on Nextel and their swap.
http://www.911dispatch.com/information/nextel/nextel_plan.html
As for Cingular's spectrum future - I have a contact in your engineering group in Hoffman Estates. He said there are no plans to rollout UMTS on 850 (i.e., all UMTS will be 1900 only), but there are also no plans to vacate (I think you said "transition") off the 850 spectrum, either... I'm guessing there will be a decision made several years from now (as you noted) as to what to do with the 850 spectrum (call me crazy, but I would be very surprised if its given back to the government) ...

nextel is CDMA... att/cingular are GSM and TDMA in the same spectrum.. Tmobile is 1900 GSM only
who knows what will happen to 850... there are still lots out there that use it... I cant see it going away for quite some time...

I dont think nextel is CDMA is IDEN is kind mix with CDMA & GSM is it not? It does use simcard

actually, Nextel is iDEN - a TDMA variant ...
