Facts:
WCDMA is a 3G for GSM, UMTS is a part of WCDMA
EVDO(CDMA2000)is a 3G for CDMA
(WCDMA) (CDMA)
WCDMA - 70-140 kbps EVDO - 300-700 kbps
UMTS - 275�380 kbps
WCDMA != CDMA <----- FACT! (WCDMA does not equal CDMA)
My thoughts:
CDMA > WCDMA
UMTS will not rule the world and those history books will remain blank for years to come.
If you travel the world GSM is right for you, if you travel the states CDMA is right for you.
If you like to get a new phone every month GSM is right for you. If you like to send and receive large amounts of data CDMA is right for you.
Verizon has the best coverage, over Sprint (both CDMA) but the software on the phones **** (Verizon)! options: Smartphones; Sprint has coverage in concentrated coverage areas, more people in the target areas.
I have both PC cards Sprint and Verizon, Sprint seems to be in more spots I travel, however Verizon seems faster when I can connect to the faster network.
AT&T has the best phones! Lowest dropped calls my [explitive]!
I have had 6 dropped calls on Verizon, 4 of which in the same area in TN while traveling it is just a bad spot, and 50 million on AT&T. This comes back to the type of network, CDMA hands the call hand off to the next tower much much better. I drive a good distance often, if you are not moble and in one area during most of your conversations dropped calls are a moot point.
