EV DO Rev B
Damn, and certian carriers dont even have their 1st gen of 3g rolled out yet
Rev. B gains steam
Airvana gearing for operator tests of the CDMA upgrade
The wireless industry’s incessant march toward faster and better networks appears to be showing no signs of slowing as industry players gear up for increasing interest in CDMA2000 1x EV-DO Revision B technology, a software upgrade to the Rev. A networks that Sprint Nextel Corp. and Verizon Wireless are in the midst of building out.
“We’re seeing a lot of interest in Rev. B,” said Dave Nowicki, VP of marketing and product management for infrastructure vendor Airvana.

While there is apparently interest in Rev. B technology, it seems the next step on the CDMA evolution path—Revision C—is still in the far distance.
Perry LaForge of the CDMA Development Group said that, so far, there is little interest in Rev. C, which is also called Ultra Mobile Broadband (UMB).
“I don’t hear (interest in) it,” LaForge said.
Oh, there'll be interest aplenty if WiMax does at all well in 2008, 2009.
...
I wonder... what will we be downloading to our phones in 2008 or 2009 that will require speeds greater than 1.4 mbps!?!?
I dunno, imo rev A is as fast as I'd ever need...

Ahh, i didnt think about aircards. That would make sense. But for a phone, not so much.

Streaming high-definition video in 1080p, maybe? Though of course that'd be to laptops through an aircard, not phones.
It's a good question. Some people think the ultimate goal of very high-speed data networks such as WiMax isn't so much to provide mobile data service (though that's part of the plan), but to wirelessly broadcast video (like cable TV channels) into people's homes, for cheaper than cable or fiber can do it.

PS- Oh, and I almost forgot about 'video calling'.
Though I think most people don't really want that... who wants to comb their hair and look presentable just to make a phone call? 🙄
I guess it'd be good for dating services... the guy and the gal can find out if the other is an uggo before agreeing to a date.

It's good for Sprint because they can get into business other than Mobile phones. Clearwire for example provides fixed-location internet services for home and business using wi-max.

Yeah, I think that is the plan. Sprint does need to diversify, 'cuz their gettin' their asses kicked in the mobile space right now.
Providing video and broadband to the home wirelessly while sidestepping 'last mile' problems/costs would seem to be a very intelligent use for WiMax (and Rev C evdo for that matter, if its economical to use it as such).
...
I could see that taking off in 3 or 4 years. The quality would have to go up, the plans would have to get much cheaper and have more minutes, and it would have to be a much more common feature in phones which will take a long time.

Sure you get 9.3 MBps but that's on two channels. It's still get only 4.65MBps per channel (though wikipedia says its's 4.9MBps).
Here are the numbers first
(download per 1.25MHz/upload per 1.25MHz)
Rev. 0: 2.45MBps/0.15MBps
Rev. A: 3.10MBps/1.80MBps
Rev. B: 4.90MBps/1.80MBps (but channels can be combined to get faster speeds... like the 9.3MBps/5.4MBps example above using 3 channels)
Rev. C/UMB: 17.50MBps/4.69MBps (up to 16 1.25MHz channels can be combined making 280MBps/75MBps possible if you can get access to that much spectrum at one time. This is considered a 4G technology btw)
