AT&T 3G Upgrades Degrade 2G Signal Strength 210

Timothy R. Butler writes "Much to the chagrin of owners of various 2G cell phones on AT&T Mobility's network, including the highly visible (and originally highly expensive) first-generation iPhone, we have discovered that AT&T has been quietly adjusting its network in ways that degrade 2G network performance as it has sought to build out its next-generation 3G network. Many of the phones affected, including BlackBerry devices, are still well within their two-year contract period."

      Not really planned obsolescence, appropriating resources for the new revenue stream forsaking existing customers.

      This to me seems worse as they are stealing services paid for by existing customers, instead of just letting their stuff expire as obsolite.

        It seems like this would be fine, if there were an open market. But to lock user's phones into a particular network, lock users into multi-year contracts, then downwardly adjust service, seems a little dodgy.

        I don't doubt that shifting spectrum to 3G is the right way to go... I'm just not convinced that now is the time and this is the way.

        • There are a lot of identical prices/features in the plans the major 4 providers offer, so much so that it seems like an odd coincidence if this is truly a competitive market between non-collusive entities.

          For example, say I want to buy a laptop cell-phone modem, and buy a wireless data plan. There are four providers who will sell me that, so you'd think I might have a choice of packages, maybe some carriers offering higher data limits for a higher price, others structuring their service with multiple tiers, etc. Instead, every provider offers exactly one plan, and all four have identical terms and prices: $60/mo for 5GB of data.

              I stand corrected; T-Mobile's offer is reasonably good, and gives the others some competition.

              AT&T, Sprint, and Verizon all do offer only the same $60/mo, 5-GB limit plan for data cards, though. Well, Verizon also offers a useless 50-MB limit one, for $40/mo.

              • It's probably cheaper because their 3G coverage is still small.

                I never looked at AT&T's plan before... $0.50/MB overage - aaaak! Leave it to AT&T to make Verizon look cheap at $0.25/MB. Sprint lays them both to waste by making it $0.05/MB for overage. It's still puzzling to me why the overage rate isn't more like $0.01/MB, since that is about what it costs to get the first 5GB. With AT&T if you go a gig over you'd owe over $500... seems fair! :)

          • I know that is Verizon's price. I'm unsure about AT&T, but T-mobile's is a tad lower as is Sprint's. Sprint's is particularly interestingly low for shared plans relative to the rest. This of course makes sense, as at the moment Sprint is the most desperate as they have a lousy reputation and must take the most drastic action. I'm pretty sure that Verizon has the highest prices (excepting AT&T, who I've no looked up), and they also happened to have the largest market share.

          T-mobile tries harder than the others, but t-mobile is blessed with the worst network coverage. T-mobile survives by having the best customer service, and enlightened data plan policies.

          The customer service folks are actually helpful, they will discuss how to configure unlocked iphones and other phones on t-mobile. They also unlock t-mobile purchased phones in 90 days, even sooner in most cases, etc.

          AT&T has the absolutely worst customer service. All the other carriers ('cept for T-mobile) are pretty evil. I would not be surprised at any informal price fixing... everyone is locked in anyways. But network quality is very important also, and T-mobile doesn't do well there.

          I only switched to T-mobile when they allowed their phones to do calls over the wifi network as well as the cell tower network. The coverage isn't great, but you can supplement it by placing wifi points where you use the cell phone the most... it actually is better for use in some rural areas. But my blood pressure is much lower whenever I deal with customer service, that's priceless!

      It's funny, I noticed this a month or so ago in Shreveport Louisiana. I live in an area where Shreveport is the closest 3G network. At home we have horrible signal fluctuations, but when it works Edge is mostly fine. Before Shreveport went 3G I would get 5 bars and Edge was pretty good (for Edge anyway).

      After the 3G switch, I still get 5 bars of service, but the Edge symbol almost never comes on, instead I get the weird little 'dot in a circle' that tells you you are one GPRS, and with a 1st gen iPhone that means no data whatsoever. Calls are great though.

      Occasionally the E will appear for a short time, and when it does it is like the Edge network that was there before 3G came. But it only lasts seconds, or sometimes maybe minutes, then goes away again.

      At least with this setup I know out of the gate I'm not going to get service when the edge icon is completely missing.

      The first time I noticed this I was with some people who had 3G iPhones. With the 3G disabled their phones were doing the exact same thing, so I know it isn't my phone being weird.

      This is one of the few times I feel lucky to be nowhere near 3G service, as it would make my fully functional phone not work properly, and I'd be 'incentivized' to upgrade. Now I can keep my working phone, and slightly less expensive data plan for the time being.

      Read the article again. This isn't an device interference issue, but rather an issue where AT&T is moving EDGE/GSM to a higher frequency band that has inferior characteristics to other bands that AT&T used to use for EDGE. The problem is that the higher frequency doesn't offer the same signal strength in certain places, so EDGE users who've been switched to the 1900mhz band will notice a lower signal in certain areas.

        Output power is the same for both frequency bands. The higher frequency provides greater distance loss but also better in-building penetration. So while those a further distance from the tower don't get as good reception, those closer to the tower but obstructed by an object (or in a basement) have improved reception. But everyone looooooves to complain about cell phone comapies so the story is about those with coverage losses instead of those with coverage gains.

After much arguing, they eventually just let me cancel my current plan with them and I moved to Verizon. (Yes, I know that they are evil too.)

      That's incorrect.

      First of all, in many areas of the country, AT&T (merged) sold the Cingular towers off to T-Mobile (this was the case in California). They only used the AT&T towers.

      There was a complex migration, you could read a lot about it by the people who tracked the switchover on howardforums.com.

      The only thing that you say that does make sense is about your reception. If you had an old AT&T "Blue" SIM, your phone would not access any Cingular towers. But the only thing you had to do to fix it was to get a new "Orange" SIM (which were literally orange). If you didn't didn't do this soon after the merger, you started to see reduced coverage rather quickly. A new SIM should be free if you complain about your coverage to AT&T's customer line (not a store, the stores always want to put you under contract as there is money it in for them). But even if you couldn't swing that, a new SIM can be purchased for $20, no contract extension necessary.

        I went to an AT&T store, told them my problem. They gave me a new SIM card, and all my reception issues went away. The clerk said it was common; he said that phones with the old pre-merger SIM cards wouldn't connect to all the towers, so they were trying to give everyone new SIM cards. Not sure how much of that was actually technically accurate, but the core of it is that a free, up-to-date SIM card solves all problems.

If you want a better idea of where you're get good coverage, zoom in one level from the furthest out. A lot of that partner coverage is subpar. Then look where their 3G coverage is. That's really where you're going to get a "great" signal. For two examples look at Wichita, or Omaha:

    For me I choose AT&T over technology. I have no love for the company but GSM/UMTS is a worldwide technology, and for better or worse I am backing the standard. Verizon, and Sprint both deal in proprietary technology, which in my opinion is the real problem in the US. The FCC has allowed companies to use cell technology, nasty contracts, and DRM technologies (SIMLOCK) to provide customer lock-in. IMHO the FCC should dictate the technology, and it should be the same path most countries are on, GSM/UMTS/LTE. They should also disallow the contractual lock-in, and SIM locking.

    The government picking a technology standard that enables US customers to have real choice is a good thing.

If money can't buy happiness, I guess you'll just have to rent it.
