Qualcomm today announced that it expects to have EV-DO Revision B chipsets ready to ship to phone manufacturers next year. They expect that data cards using this new chipset will be available by the end of 2007 with handsets to follow in 2008. With this announcement Qualcomm revealed the speed expectations of the latest edition of the EV-DO wireless broadband standard. Rev. B will increase download speeds to a maximum of 4.9 Mbps per channel - a significant increase over Rev. A's 3.1 Mbps, however upload speeds are apparently not enhanced. The Revision B chipset will also be able to combine three channels to further increase download and upload speeds to 14.7 Mbps and 5.4 Mbps respectively. Sprint expects to launch Rev. A early next year, so it is unlikely they will roll out Revision B in the near future. Verizon has not yet announced Revision A rollout plans, so it is possible the carrier may choose Revision B instead.

802.16e Wimax is 4G

Sprint will announce their 4G solution in Q2 of this year. I'll save you the suspense, it will be Wimax. It will be triple the speed of Rev B, you won't have to pay Qualcomm royalty fees, and Intel plans to ship Wimax as part of all notebook chips starting next year. See www.motorola.com/wi4
Sprint is researcing multiple options for 4G, including the former Flarion, now Qualcomm technology. Last I read was that 802.16 had a little trouble keeping up with a fast moving vehicle. 802.16 will be implemented in publicly held wireless broadband...
Who needs 4G? It's pointless.

HSDPA class 10 and EVDO Rev B are both capable of 3x the download speed of my cable modem, and I don't even use all of THAT speed at home on my desktop.

We don't need any more download speed, at least not until upl...

That is crazy...

Verizon has already said that they have equipment coming in soon to test Rev A sometime soon. Why would they test the technology that they don't plan to use? Seriously though, Rev A is in the final stages before release, and just because Rev B will be available "sometime" in 2008 doesn't mean that networks will be ready to launch it. Not to mention that there is no way VZW is going to let a year and a half go by that Sprint has a better technology available. VZW will launch Rev A in the early parts of 2007 just like Sprint because of the competition between the two networks for CDMA2000 technologies. Sprint already has 25% of its customers using data plans which is more than any other company, if VZW waited around for Sprint to soak up even ...
Let me also add this thought...

Sprint started seriously launching EVDO nationwide not even a year ago. So by time they launch Rev A Sprint only would've had EVDO out for not quite two years. So it seems ignorant to say that they wouldn't spend the...

sprintel in trouble??? What will NEXTEL18 do now???

Hmmm, looks like Sprintel might be jumping the gun and should wait for RevB. Q chat might not be worth beans if it is going to run over RevA which is already looking to be pointless with RevB on the horizon. I have a good source telling me that VZW will be going the route of RevB, let the leapfrog game continue!!!!

Next thing you know there will be revision F

Every time I look on here it seems there is a new EVDO revision that will roll out conveniently one year after the other one. Revision A rolls out in 2007, Revision B in 2008. Don't they realize that there are two year contracts? I suppose it's another way for the phone manufacturers to try to increase their market percentage. If Verizon is smart they'll look past revision C and move directly to D so they can one up Sprint. But I doubt that, since Verizon likes to have totalitarian control over their handsets. In fact it seems, judging by the level of control that Verizon likes to have, they'll instead have a revision A and a half, and make their customers only use it for uses of Vcast, and paying th...
No by then 4G technology will probably be good enough to roll out in 2008. And 3G phones will be cheaper.
