Not to mention cdma can use multiple towers simultaniously making hand overs seamless.

Good info Barciur
I'm not a moderator, I just read a lot at work because I have nothing better to do, and can remember fairly accurately things that I've read in the last few years or so.
Lower frequencies do penetrate buildings better, last I read TMobile only uses the 1900mhz which means it may have a problem in certain buildings. Powersource/Hybrid phones also only use 1900 for the phone part so it will have more problems inside.

i know that just from the experiences i've had, I'd never go back to GSM

Unless you visit europe. And a side note, cdma does penetrate buildings better for two reasons. cdma naturally travels farther than gsm, and with cdma you can hold a crystal clear call with less reception than gsm.
I've heard that towers are effective up to 10 miles. The question is, is that radius or diameter.
This is accurate. as for travelling up to 22 miles, that's a joke. even if a tower could transmit that far, your phone couldn't transmit back making it useless. and the reason cdma travels a bit further is cdma uses the 800 mhz vs. gsm's 850 mhz. while the distance is minimal, it could still make a difference whether your call goes through or not.

LOL.
824 mhz - 849 uplink for GSM 850
869 - 894 downlink for gsm 850
and it could have an effect with CDMA - yes, in an extreme situation. which is rare
the whole still doesnt explain why european GSM covers 99% of the population (in poland at least). that just proves it can be done with GSM.
