Where's Your 'D-Spot?' 262
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.

Crappy reception at home. AT&T converting sit (Score:4, Informative)
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.

Take one antenna and put it in your living room or where you want to do most of your calling, then put the other one outside, on the roof or in a window that gets good reception with the cell phone normally.
Hook them together with some 50 Ohm Co-ax, RG-58 will do nicely but not for more than about 50 feet. If you need more length get a lower-loss Co-ax like RG-213 or RG-8.
Then, go in to the area where you call from and try it. You might be surprised. A buddy of mine worked for Motorola in an RF lab, and he couldn't hear his local Ham Radio repeater, so he did exactly this in his lab (read: Faraday Cage) and hooked an antenna inside the lab to one on the roof and it worked! That was at 440 Mhz, but cellular should work fine at 880 Mhz as well.

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.

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.

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...
