So carriers that broadcast on the 850mhz frequency have the luxury of requiring the least amount of cell phone towers. The other frequency that carriers uses is 1900mhz, and while that frequency doesn't travel as far/penetrate things as easily as the 850mhz frequency, if the carrier builds more 1900mhz towers, their coverage can be as comparable.
In my area, Verizon and Alltel are the two carries on the 850mhz frequency. All of the other carriers (Sprint, AT&T, T-Mobile, etc) use 1900mhz.
I've had Verizon (via work) for the last two years. Nowhere have I gone in this area where I've had a problem with my Verizon service being less than perfect.
With my iPhone's AT&T service, I've been less than impressed. I'm seems to work OK when I'm outside of a building, but it's much less than Verizon's coverage inside buildings. Specifically, both my house and work get less than optimal AT&T service where either it has 4 bars (yay) or 2 bars (blah) or No Service. I mean, the phone's sitting in the same place, and the service bounces in between those settings. ITS CRAZY! And at home, my two roommates have iPhones. I may have 4 bars in the same room that the one of the others may have No Service. I'm not sure if that's the problem of Apple or AT&T but it's surely a problem I've never experienced with any Verizon phone.
I was so fed up with the problem that I returned my iPhone on Friday, but after being a day without it and having watched my roommates with theirs, I'm starting to reconsider my decision. How crazy is that????
