>I read that just for cdma you need 2 times more towers
nonsense, for CDMA-450 less just because they get further.
450 is generally safer. Less towers, lower frequency.
>by name 2 Gt
2000 is the year of invention, not frequency.
>3G is wcdma based on gsm and cdma-800
who said such nonsense?
I repeat: 3G is a common name, it includes both HSPDA from GSM and EVDO from CDMA. By the way, Skype says that EDGE is also 3G. Probably wrong, EDGE - 2.75G.
CDMA-800 operates in America mainly in CDMA-450 in Russia (Skylink) and China.
GSM in Russia, at least in the European part - 900.
So it turns out that Sky is 2 times safer than any operator.
P.S. EVDO Rev.A: receive 3.1 Mbit, return 1.8. HSPDA: 3.6 Mbit reception, feedback ... And here is FAIL - the return is very small, I don’t remember how much I remember, but very good. few. I will upload the same pictures on twitterpick a few times longer if GSM.
P.P.S. "GSM" is associated with "GSOM", which means - I think
understandably.
