CDMA is great for voice if you aren't running whatever ****** codec verizon runs while being overloaded at the same time....oh but wait this is just the standard with any wireless network .CDMA is great on USCC and Sprint for voice for the most part, my friend seems to drop a lot of calls on sprint though...I blame sprint lol.
I'd say EVDO is decent for data. What is interesting though is that EVDO is similarly as efficient on the air interface as HSPA yet AT&T's average was a lot faster with less spectrum devoted to 3G as a total (due to sharing with GSM/EDGE). A lot of this has to do with dynamic balancing of voice/data in the carrier though. Even still for similar networks AT&T really isn't doing bad. I think the reason why T-mobile does better is simply because they have less users, higher cell density, actually have 64QAM, and haven't been selling 3g phones for very long compared AT&T nor did they have the 3G penetration in their line up for as long.
Geeze look at Sprint's 3G average lol. Sprint's WiMax average is not much faster yet AT&T managed a higher peak than WiMax lol.
Now EVDO/HSPA isn't going to perform like a new LTE network primarily because those networks are basically handling all the devices so that isn't really any surprise here.
