Cell Phone Reception Hack 142

But Graeme, who writes a blog called 'Earth: Mostly Harmless,' gives us hope. Succeeding where most would quit, he chronicled his ingenuity in a post titled 'How I got mobile phone reception where there was no signal.'"

Do you know where to buy ancient phones and accompanying service? I'd be amused to have a bag phone or an OKI (they're really cool old hackable analog phones--remote controllable with DTMF, reprogrammable to display a list of other calls on the cell and let you select one to listen to, computer controllable, etc...), but I don't know where to buy them, and I don't know how to get service for them. (The cheapest plans most companies have now are around $40-$50.) Thanks for any pointers you can give.

Verizon's counter-kids don't even know what the word "analog" means anymore. When I talked to the old guy in back, he laughed me out of the store.
The folks at Cingular, who I had service through several years ago but let lapse, thought it would "kick ass" to see "that old beast" running again, so we spent 2 hours trying to get their online activation system to do our bidding. I downloaded motbib23.txt and broke out the screwdriver while standing at the counter, but we couldn't get their system to take the phone's ESN. In the end it was fruitless.
None of the other places I called would even acknowledge that "analog" or "amps" or "brick phones" ever existed. Bastards.

Yeah, pretty much.
I don't want to be too hard on the guy, because it sounds like this was his first antenna project, but the whole article just makes me a little sad. What he did isn't even all that hard, and if he had done a little more searching around he would have found literally thousands of pages and hundreds of articles, complete with formulae and schematics, on how to build antennas of this type.
There's an amateur radio band located just above (and IIRC overlapping slightly with) the 2.4GHz ISM band. There's tons of antenna construction resources; the American Radio Relay League has two volumes written about the topic [arrl.org]. (Although it covers a lot more than just antennas, admittedly.) Although I don't own the book, I'd bet that most of those articles probably have equations for scaling the dimensions to particular frequencies, so it would be trivial to do what he was attempting. (And a quite likely a violation of FCC rules, but that's another story.)
On a more general note, it's a little sad to see how little of a connection there is between the radio "hacking" community and the computer one. Perhaps it's due to there being a generational gap in there, but I've never met two groups of people that have as much in common, philosophically, as computer hackers and ham radio tinkerers. When I read articles like TFA, where the author says "To my knowledge no-one has built a homebrew biquad UMTS antenna before..." it just really underscores how poor a job the amateur radio community has done in connecting with computer geeks. The topic at hand here isn't something breathless and new, it's well-understood to the point of probably being boring. But because of the lack of connection between the two interest groups (even though, as in this case, they have a lot of common interests even if they don't realize it), we have computer geeks painfully reinventing the basics of antenna design, and we have ham radio operators who haven't in some cases even figured the Web out completely, much less how to use it to collaborate.
That's not to say that there aren't computer geeks who are into ham radio and vice versa -- the number of radio-related software projects is testament to that (as am I, and others here on

Last week, my T-Mobile Motorola phone would show 4-5 bars, and when I tried to make almost any call (including voicemail), it would sit for 5-10 seconds, then simultaneously drop to zero bars and show the "Call Failed" message. The interesting thing is that there were two numbers I could call that worked flawlessly: my house's landline, which is probably on my T-mo records, and the tech support number (I think I just dial 611 on my cell to get it). Further investigation on my own led me to believe that my phone was receiving a "fast busy" signal, but that the phone itself would just give the "Call Failed" message rather than let me hear it. Further investigation found that my friends who had been trying to call me received "fast busy" signals. -Further- investigation found that my sister's phone, which is also on T-Mobile, was having the same problem.
I calmly told all of this to someone at support. The frontline person asked a few script-type questions which seemed to want to blame it on my phone or the local weather. Luckily, the weather was flawless that day and my sister's phone was having an identical problem. Since she couldn't blame it on either of those, she forwarded me to an actual -tech- support. The actual tech support person was also very polite, and seemed to be able to check network status for any sort of regional problems...unfortunately, she couldn't really do anything to help. The final answer was something like "we've had some reports of problems and the engineers are working on it"...I could tell that was the best I'd get. She did give me 50 extra minutes, which is at least something (although I also found out that there was now a plan identical to mine at the same cost except with an additional 300 anytime minutes...so I guess I just got ripped off less this month).
Further research on fast busy led me to believe that some part of the local network was saturated...seeming to me like the kind of problem that would have been anticipated in advance if there was any actual hope of it being solved.
Anyways, my main advice:
1) Don't be afraid to call tech support. If you do, be calm, be ready to wait a few minutes if need be...but first make sure that you do a few things:
2) Before you call, try to verify that the problem is not your phone. Power cycle your phone. Try a couple numbers: cell phones, landlines, voicemail, and see what works or doesn't. Have a cell phone and landline call your phone. The more specific you can make your information, the less troubleshooting they'll try to talk you into on the phone, and the faster you can get things done.
3) Don't expect anything major in return.
4) Be nice!
I've pretty much resigned myself to defeat as far as cellphones go. Only once have I ever felt like my cell plan was a good deal (and it was when I first started with T-Mobile). Before and since that time, I've always felt like I was getting ripped off in various ways that I couldn't control. I've never had service in my house/room, but I've almost always had perfect service in my friend's homes/rooms. And, it's pretty obvious that whoever is designing phones and their menu systems has never used a cell phone in their life: it takes at least a full half-second for any button presses to cause action on the screen. The menus are a mess. Several years ago, in about a 12 month period, ringtones went from being something that anyone could make their own and easily upload to their phone to a $1 billion industry. A $1 billion industry created in a year at the expense of consumers.
Nothing anyone can do, because the convenience of a cell phone is still too nice to pass on, and they keep the prices just low enough that we'll still pay. Someone submit a story if some investors ever get together and offer relief somehow.
