Where's Your 'D-Spot?' 262

Posted by timothy from the can-at-least-now-use-cingular dept.
John Hering writes "The battle between cellular carriers in the U.S has become especially fierce within major metropolitan areas. The focus of this battle clearly revolves around issues of quality of service (QoS). In an effort to demonstrate superior QoS, AT&T Wireless has just released the results of the Top 10 "D-Spots" in Chicago from a survey conducted online with a random sample of 520 Chicago men and women. Although AT&T touts improved coverage throughout these metropolitan areas now, the vice president of AT&T Wireless, Greg Slemons, has publicly admitted to serious problems with dropped calls. " I have yet to see really detailed coverage maps for cellular provided by the providers themselves; in cities especially a one-block difference can mean 3 bars of reception or none.

The metal frame used to attach the stucco degrades the signal to the point where my phone is unusable inside but I get awesome reception by stepping out to the back yard.

      Anyway, I can't use my cell phone in my own house, which rules out using it as a land line replacement. I can barely get decent reception in my back yard.

      I now have a similar problem in the "East Bay" of the SF area.

      My house has aluminum foil on the vapor barrier of the insulation, so I expected poor reception when I first got my phone. But it worked fine at that time. (Proababy due to the large windows.)

      But lately my reception all over the east bay has been getting rotten, and it has been virtually impossible to get a connection at home.

      The phones aren't flaking out. (I've enabled the field test mode in both mine and my wife's. The signal strength meter still indicates about the same strength it used to on the road, and the two phones agree.)

      But I've recently found out that AT&T wireless is converting many of its 800ish MHz TDMA cell cites to GSM. (My phones are TDMA.) With the reduced number of TDMA channels available I now have some major dead spots - at home, at work, near the 880/237 interchange, etc.

      Even when I DO see good signal strength, making a call will often make the signal disappear. I think what is happening is the phone is reporting that it's in communication with the cell on the control channel - but when all the signal channels are in use so you can't get a new one, the phone reports it as "service unavailable" as if it couldn't reach the cell.

      Unfortunately, I have already purchased a pots-adapter cradle for the phone model in question, to use the phone for service in my vacation home, and this wouldn't work with a newer phone. GSM has lower voice quality than TDMA. I use the phone for travel, and TDMA+AMPS coverage is still far broader than GSM+TDMA, and there are few (one?) GSM+TDMA+AMPS phone models available. And if I switched I'd either have to buy the phone or lock into the service for two more years.

      So I am in no hurry to switch to GSM. And if I do (and if Verizon has added coverage at my vacation home location, which wasn't available when I first got a cell phone) I'll want to switch carriers as well.
    • I tried Sprint, got zero reception in my condo (unless I stuck my head out the window). Tried AT&T, reception is good = no more landline, cheaper phone bills. Figure out where you spend the most time on the phone (i.e. home, work, traveling), and then find the carrier that gives you the best reception in that spot. There are huge differences between carriers.

    I have been with several wireless providers, including AT&T, Verizon and T-Mobile. From my experience so far, AT&T had the worst service of the three. T-Mobile has been growing fast, and I get amazing coverage wherever I have gone. In fact, I've actually seen the network expanding. On my annual drive from my home in California to college in Colorado, there used to be no service at all in Nevada or Wyoming. Now, I have full service on the drive through all those states. I have also found the customer service to be excellent. That's just my 2 cents on the cell phone battle... I think T-Mobile is trying very hard since they are move of an up-and-comer than a giant like AT&T.

      T-Mobile's service may be getting worse, at least in the California/Nevada region. Here's a little history.. unfortunately, I don't know dates.

      1. AT&T forms AT&T wireless
      2. AT&T spins AT&T wireless off as a stock symbol
      3. AT&T sells AT&T wireless to investors (so it is no longer part of AT&T but carries the name)
      4. Cingular buys AT&T Wireless, but not the name
      5. (in the future) AT&T will release an in-house brand of wireless known as... AT&T Wireless, but using Sprint's towers instead of the GSM towers.

      Currently all AT&T customers will be or have switched over to Cingular.

      Now for a little background on Cingular and T-Mobile. At least in California, I can use either Cingular's towers or T-Mobile's towers for free (I'm a cingular customer). This is because T-Mobile did not have any service out in CA and NV and Cingular had really bad service in NY. Now that Cingular has bought out AT&T Wireless, they could easily break the agreement with T-Mobile since AT&T has great coverage in NY. T-Mobile gets the shaft by having to either stop offering service in CA and NV or put up a lot of towers.

They've since moved into town... but are having an awfully tough time convincing people to even set foot in their stores. The impression of being a zero-service carrier in this area is just plain a hard one to shake.

      I finally dumped AT&T as my wireless carrier after a marathon of bullshit. You don't have to read the story below. I'll be happy if you (and everyone you know) just refuses to do business with them ever again.

      Long story short:
      o lousy signal and poor reception EVERYWHERE
      o connections that mysteriously go bad at exactly 4:00 minutes into the call (unless you're calling AT&T)
      o months of phone calls to their so called "customer service" getting put on hold, transferred at least three times, then dropped
      o "corrected" bills that never show up
      o same billing mistakes repeated month after month, with compounding fees and charges
      o wasted a day in the store with a face-to-face that took over two hours

      o the final straw: they disconnected my service in the middle of an extremely important phone interview. This after I had been assured my newly fixed bill was on it's way, and that there was plenty of time in my billing cycle -- BTW: the disconnection occurred on the same day I received the new (and still incorrect) bill.

      o I gave AT&T what turned out to be yet another three hours of my time (five phone calls due to being dropped four times). I gave them every chance to be reasonable -- finally just spelling out a list of demands and suggesting they have someone call me before close-of-business if they wanted to keep a customer. They'd rather transfer me 15 (yes, fifteen) times, asking me to reconfirm my address and re-tell my whole story each time.

      By now you're thinking this was a long way to go, especially when it's so easy to change carriers these days. But, I had been a CellularOne customer since 1989 before AT&T took over last September. Think about that! Fourteen years! I had always been able to work out problems before. I had a bunch of resumes out with my cell number on them. (And I really didn't want to punch my whole address book into a new phone!)

      Too bad, AT&T. You took a winning, mutually beneficial arrangement, and turned it into a losing proposition for both of us. Say good-bye to a fourteen-year customer. One who had multiple phone lines and had, at times, spent thousands of dollars a year on telecom.

      You'll never see another cent from me. It's all going to one of your competitors now. The money you think I owe you? Try to collect -- I'll make you spend even more.

      Forget about ever getting a recommendation or referral. In fact, every time your name comes up, expect me to tell my story. When I see your other customers on the street, I'll strike up a conversation -- guess what the topic will be. In a business setting, I'll advise people to build their own phone company before choosing AT&T.

      Oh, you've also managed to anger someone who knows how to use the internet. Know how to remove piss from a swimming pool? You're welcome to try.

    I really wish the embeded-in-the-car cell phone hadn't gone out of style. Next time you're in the passenger seat of somebody's car, compare the reception of the car's AM/FM radio to the reception of a handheld Walkman. It's just plain going to be no contest on stations that are not extremely local. The car radio has access to a nice big antenna outside of the car, the handheld device doesn't. Simply put, you'd get better reception in your car if we still had the little swizzle stick on the roof.

    The second most annoying dead spot is the home, and exactly the same principle can apply. A roof-mounted mast gets much better TV reception of stations more than 10 miles away than rabbit ears on top of the TV set.

    Bluetooth or WiFi would be a great tool to use in order to make the "last mile" link between the handset and the actual RF transmitter and reciever. Why should the user be expected to walk around their own home because one side of the house has coverage but the bathroom doesn't? It'd do wonders for apparent coverage and battery life if our handsets would pass off the task of actually speaking to the cell network to hard-mounted devices that have access to either grid power or at least the car battery, so the device in our hands can save its battery life for the times that we're really out on the road and need the handheld transmitter.

    The dead spot that's most likely to make a user switch carriers isn't the airport, it's the places where the user spends the most of their non-working time... their home and their car. If they're getting cell calls on company time, then the company's responsible for picking and paying a carrier that works at the work site. Still, a localized dead spot can usually be solved simply by using a short last-mile connection to get to a high point outdoors where radio signals usually are clearer...

    I've travelled all over Texas quite a bit, based out of San Antonio, and use AT&T for my work cell phone.

    In any of the larger towns (50k+) it tends to be good, without many dead spots.

    The IH35 and IH10/90 corridors have good coverage.

    Taking 281 between San Antonio and Dallas is another story. If you've taken this route, odds are good that if I mention 'that McDonald's on the hill in Lampasass,' you know EXACTLY what I'm talking about. This is the only location for about 250 miles that you can get a signal.

    Of course, west Texas heading towards El Paso or heading up towards Amarillo is mostly dead once you turn off IH90.

    Most of the sticks have spotty service, which unfortunately, I'm in too often. I'm told that Verizon has good coverage in these fringe areas.

    I've used my AT&T cell on trips taking me to Denver, Burbank/Valencia California, and to Calgary/Banff (Canada...duh). All those locations were good.

    Odd spots:

    The Sybase offices on the 19th (?) floor of Lincoln Center in Dallas. If you put your cell phone down on the table, you can watch it rotate between Digital, Extended Area, and Roam, and watch the antenna bar go up and down--while the phone sits still.

    The Amerisuites near Aurora (Denver) Colorado. As soon as you walk into the main lobby, your signal dies. Step into the elevator, and as soon as the doors close you get a signal again. It's clear all the way up and back down, until the elevator doors open again at the lobby. Walk outside the lobby about 30 ft from the building, and you get a full signal again.

    Hey, it beats the hell out of Sprint PCS. That was just a total POS, and rarely worked at all.
    • Just take IH-35... then you can have coverage while you sit in a traffic jam going through Austin. :) (Yeah, I'm in Austin. Yeah, we need a bypass.)

      I switched away from AT&T mainly due to their crummy coverage throughout central Texas. I'm surprised that you haven't been able to roam onto T-Mobile around 281, though; they've got a much nicer coverage footprint around here. The day I went out to Enchanted Rock and was able to see (but not use!) their signal was the day I decided to switch.

      • Austin is the only reason to take 281 instead of 35 =P

        I haven't gone that way in a couple years. Perhaps it's improved.

        Besides, my phone may have been partly to blame the last time. I started losing signal more and more often (Nokia 6160), so finally replaced it (6560).

        I really don't like it--slow as hell, and reception is better, but still a tad flaky. Unfortunately, it's the only phone they offered that had a somewhat 'normal' keypad on it. Now you have all these damned circular rockers and othe

    I know that T-Mobile has very detailed maps that employees may access -- I'm sure the major carriers have this as well, so just ask a salesguy when you look into your next phone.

    Since my area is a little rural, but between some big cities (Baltimore and DC), my cell reception can vary wildly. So I asked the rep at the store, and he goes on the internet and shows me very detailed maps of their coverage (tenths of a mile in scale). I asked if I could view these pages at home, and he said it's only for T-Mobile use, and so it's not publicly available. But the data is there.

    • Yeah we've got internal maps (I work for a rural cell carrier), we pay lots of money for those and have to keep them confidential to stay competitive. If $big_cell_carrier knew we had a known dead spot at the mall, they could have their sales people ask "Do you go to the mall, our service works and those other assholes don't", we would be farked, our internal maps (and call accounting) allow us to capacity plan for dead areas, if we are really losing traffic at point A and there is a business case for it,

I tried it anyway (because no other carriers worked at my house, and I have a work phone anyway), only to find I do get reception (2/5 bars) -- good enough that I've never dropped a call. YMMV, but that's my case.

    You likely never will. Before getting fed up with the IT industry, especially the corporate IT industry, I was a technical manager at AT&T Wireless. My team worked on a GIS project to show coverage data, among other things. We wanted to use the actual coverage information which would have shown gaps in the coverage and everything, but the legal department wouldn't allow it. Instead of actual RF propagation data, we wound up using hand drawn approximations, then forbidding the user from zooming in to a level of detail that they could hold us accountable for the accuracy of the maps on a local level. Because Engineering already had the data in a compatible format, it would have actually been easier to use the true data... Oh well... :-)

    From the article: "In addition to the survey, AT&T Wireless customers who enroll in the new national plan, GSM America, as well as those already on one of the company's qualifying national GSM plans, automatically get the benefit of paying no roaming charges anywhere in the United States. " The implication is, where there's a signal, you can call. But, the truth is quite different. No charge for roaming means limited roaming. Roaming only where they have agreements in place - not everywhere there's a signal.

    Coverage is a major problem with AT&T Wireless in the Los Angeles area. So bad, in fact, that there is a pending lawsuit about the matter, Petrove, Wireless Consumers Alliance, et. al. v. AT&T Wireless [lchb.org]. The page has not been updated recently, but it's a live case that is working its way through the courts here. I believe they are trying for class action status if they have not been granted it already.

    Basically, the case centers around alleged false advertising claims made about coverage area. I can personally tell you after being stuck with a bad contract that the AT&T coverage area sucks, as I can't drive on the freeway for more than five minutes without losing (or "dropping") a call. The page talks about one lady who was carjacked and got shot in the face after she tried to call 911 but her cell phone didn't work. About two months ago I saw an accident on the 210 Freeway where the driver was bleeding and knocked unconscious. Over the course of a few miles I must have called 911 like five times on hold, then getting cut off, then finally dialing the operator. Instead of the local city the cell operator transfered me to San Bernardino County, which is about 30 miles away, and the dispatcher asked me to try again. I had to tell him that my cell phone wasn't working so he had to make the call for me, oh, and by the way, I might get cut off again.

    My whole experience with the calling areas here has been bad, but I'm not sure quite as bad as my experiences with the cellular contract that got me here in the first place. Luckily, it just expired, and I am switching carriers ASAP -- that is if AT&T has gotten its number portability together [slashdot.org]. Bad AT&T Wireless service is a common theme [toyz.org] in the L.A. area.
