Could this relieve 2G congestion?

I live in Oklahoma City, and AT&T's 2G network has had poor call quality for a couple of years. They have so many users here that peak dayparts really seem to overload the network. Could the improved 3G reception mean that 3G phone users will remain connected to the 3G network consistently and take a few of the users off of the overcrowded 2G network?

I made the move to T-Mobile a few years back because of AT&T's call quality issues. This may be enough to bring me over to AT&T. (We still don't have 3G here on T-Mobile.)

Possibly.

I do not know if they turned off the 1900 3G while turning on the 850 3G. If they did, it may or may not alleviate the congestion problem. However, since most of the phones that AT&T uses are 3g phones, it probably would not matter.

BTW, I believe T-Mobile is scheduled to turn on 3g in okc in Q4 09.

If you are right about the congestion, that would be too bad... T-Mobile's OKC buildout is really pretty good, so I'll probably just stick with using my e63 on T-Mobile for now. I hope T-Mobile does turn on 3G during Q4 '09, though I haven't seen any evidence of work on the towers in my area just yet.

I live in OKC, and i notice a lot more better signal and call quality. Now I always have 3G, I havent even seen the EDGE not one bit. You should try it out, I always been happy with AT&T but 3G is superb now.

Thanks for sharing your observation. My father-in-law just picked up a $99 Iphone 3G last weekend, and it is getting a good 3G signal all over the place, including in his basement. He lives between Choctaw and Harrah, which is basically a hilly rural area. This is pretty impressive, imo.

I'm going to be honest, it wont directly impact 2G service because it only affects 3G devices, giving them better coverage and more bandwidth (higher speeds & Calls handled at one time).

But what does affect Oklahoma City's 2G network are the customer that upgrade from a 2G phone to a 3G device, that releases strain on the 2G and adds strain to the 3G (hence the reason they added more 3G spectrum).

Personally, I would suggest always opting for the 3G device, although its more expensive you will have minimal impact with electronic devices "freaking out" when a call or text come in. Not to mention incomparable data speeds.

I understand that it only directly effects 3G devices, but that effect could indirectly impact the load on the 2G network. I've spoken with some whose 3G phones would frequently revert back to the 2G network when indoors. That would mean that there was a larger load on the 2G network. Now that 3G is on 850, those users of 3G phones should no longer experience their phones reverting to the 2G network when indoors. It would seem that the 2G phones would be the only ones still using the 2G network.

I wonder what percentage of AT&T customers have 3G phones...

yep, yep. You answered your own question my friend. By keeping 3G users on 3G and not having them switch back and forth to 2G/EDGE...

No, murmermer, your analysis is typically superficial. W-CDMA 850 deployment can affect GSM service, as a W-CDMA 850 carrier channel requires 10 MHz bandwidth -- fully 40% of a Cellular 850 MHz license's 25 MHz bandwidth. When AT&T deploys W-CDMA 850, it may take that 10 MHz bandwidth away from GSM 850. That reduction in GSM 850 bandwidth can force more users to GSM 1900. And that shift can lead to degraded GSM service & coverage, if the network is not fully optimized for PCS 1900 MHz propagation.
