Just what do you mean: 4G wireless? (vs. 3G wireless)

[Jeff Hawkins]

There is discussion about "4G" networks vs. "3G" ones, but there doesn't seem to be any threads asking the more basic question of 'what is 3G?' and 'what is 4G?' and 'How do the 2 compare?'.
So I'll start a thread here for those questions. If you know, please respond! Lots of 'newbies' wanna know!

I don't want to sound rude, but it's simple to research through the your preferred cellular provider. 3G has been around for several years, while 4G is obviously the 'newest' "generation" (G) in the CDMA (now WiMax) data delivery.

1xRTT was first, then 3G, and now 4G for the CDMA technology.

I know I should let you all do it yourself, but there is the wiki pages.

I see on Sprint's maps they have 4G in Chicago and Dallas so far in the central US. I didn't look around too much but I'm sure there are a lot of other areas as well. I'm impressed with how fast they are rolling it out.
