I used to have crappy coverage (non-existant at home) until I switched to Verizon (800 mHz CDMA G3). It works flawlessly. You can switch providers and keep your existing number. It's called ''porting''. Radio Shack are the experts. Porting is old news by now. But I would not trust what a Radio Shack rep says. Time after time I discovered that I knew more about a product than the RS sales clerk. -- John Richards |

And, Verizon is known around here for having great coverage in rural areas, which Sprint does not. This leaves me with evaluating the audio quality of the phones themselves (not the network, but the individual phone models). |

I use SprintPCS with a 4 year old Motorola StarTac ST7867. Just moved to a new house and I can barely get a signal unless I stand in the middle of the yard. That's problematic in winter. After grilling a couple of customer service reps on the phone, I stopped into the Sprint store today and came away with some questions I need answered before I terminate my service and try another provider 1) The salesman was the first Sprint employee I've found who was actually able to show me the actual location of antennas. There's one a mile from my home, and 2 others within 5 miles, with no obstructions of any kind. No hills, no tall buildings, just trees and homes. He says this explains nothing because he signal is highly directional. True or false? Resoundly True. Cell sites use directional antennae... in fact in an area where buildout is mature, they sort of have to. Cell sites, even those that operate on CDMA as Sprint does, are sectorized to reduce interference with neighboring cells on different pilot signals. 2) His next suggestion was (of course) to try a newer phone because mine uses "older technology" which might not be able to pick up such a great signal. Likely or not? Actually, very likely. The 7867 is a 5 year old design at least, and the network has changed quite a bit since then. The carriers have worked to squeeze more capacity out of the network, and in CDMA that means a generally higher signal to noise ratio (in CDMA, all other conversations happening on the same channel are "noise" to your particular handset), and thus greater tolerance requirements for a higher noise floor. This has forced chipmakers (mainly Qualcomm) to come up with better, more sensitive RF stages for newer handsets. The result is your old phone will still work with the present network, but not as well as it did four years ago even in the best of circumstances. If you put a current-model Sanyo side by side with your StarTAC, the Sanyo will probably receive a better signal nearly all of the time. 3) Here's the tricky part: I'm not totally adverse to a newer phone, even though I have absolutely NO need for color, email, songs, games, digital pictures, or any other crap. I just need a friggin' phone. But, I've made an observation over the past few years while listening to the sound quality when people call me from THEIR phones. It seems that some manufacturers have gone WAY off the deep end when designing their noise cancelling arrangements. In many instances, background noise causes the phone to also kill or scramble the voice of the user. This, of course, makes the phone useless. I make quite a few calls from my boat in high winds, and people tell me that as long as I'm manually dealing with the wind somehow (turning away, etc), the phone sounds like a normal phone as opposed to some sort of special effects in a B-movie. Yeah, a casualty of the need to squeeze capacity is sound quality. Vocoder ("VOice enCODER") bitrates have gone down, and that means your StarTAC which uses a 13kbps vocoder will sound better than the 8kpbs/variable-rate vocoder on today's phones. However, some phone manufacturers are still better than others. A lot of people (including myself) swear by the Sanyo models. Samsungs aren't all that great, and the jury is still out on LG. Of course nothing, not even a StarTAC, beats the sound quality on the original Qualcom QCP-2700s that Sprint first started out with back in 1996. I had one and could swear that phone sounded as good, and sometimes even better, than a landline. It was small and light, and it was solidly built... if you smashed the 2700 against a brick, my bet would be that the phone would win and the brick would lose. Sadly, none of that is true with current phones from any wireless carrier these days. Before jumping ship, I would give the Sanyo 4920 a try. It's the descendant of the 4900, which Sprint users have been raving about for a while as being the best phone (of current models, anyway) for call quality and for holding a signal. -- E-mail fudged to thwart spammers.

I have a 5 year old Kyocera 2-mode cellphone and it works much more reliably in a fringe area vs. my new Audiovox flip phone. My GF also has an old Audiovox and it works superior to the newer ones. In their efforts to make the phones compact and add features, they really don't seem to be paying attention to signal quality. b. |

Sadly, none of that is true with current phones from any wireless carrier these days. My wife JUST switched to a new phone at the beginning of this summer. she WAS using one of the old Qcp-2700's. The only reason she switched phones was (1) the difficulty removing the battery (having to use that nifty specialty screwdriver), and (2) She couldn't find any new batteries for it . |

Connecting two antennas back-to-back makes a passive bi-directional
repeater. It's a cheap solution useful where the field strength from each transmitter is high at the antenna which is pointing at it and there is an obstruction between the transmitter and receiver. I used this technique successfully on a 13 mile bi-directional analog video microwave link, with a 1/2 mile dogleg from the top of the hill down into a valley. The hilltop site was unpowered and accessible only with ATV but was a lot cheaper than putting up a 300 ft tower. It should work with cellular telephony as you suggest. The trick is to capture enough energy from each transmitter to overcome the transmission line losses and lay down sufficient signal strength at both receivers. If you can't make it with antenna gain, then you'll have to go with an active repeater.

I have a Motorola 343 and it sounds very pleasant (for digital). Plus
it has this handy featu you don't have to unfold it. It's one of the new ''one piece'' designs. On Tue, 12 Oct 2004 18:32:42 GMT, "Doug Kanter" wrote: "David" wrote in message .. .

However Samsung's cell phones, for lack of a better term, are total ****. Every Samsung cell phone I've tried from 1999 all the way to the present are cheaply constructed, have horrible audio quality, and couldn't hold calls even when I was outside and in plain view of a Sprint cell tower. The exception is NEC/Mitsubishi. All of their products have proven to be mediocre. ![]() -- E-mail fudged to thwart spammers. Transpose the c's and a's in my e-mail address to reply. |

Talk about dumb, though: When I first got a cell phone, I signed a 1-year, 29.95 per month contract with Sprint. At the end of the contract, I did nothing, they said nothing, and I just kept paying the bills for 2 more years. I called the guy at the Sprint store this morning and mentioned the Sanyo phone. He said that in order to get that phone, I'd have to upgrade to 39.95 per month. I asked how a monetary issue is connected to the particular phone, and he sort of mumbled something about the purchase deal for the phone. He's checking with his supervisor blah blah blah. |
