i had a question about EV-DO... what does that mean/what is it i saw people talking about it and i just wanted to know what it was
thanks.

[JoMamma]

lol me 2. (and hey how do u like ur 4050 PM me cuz i am thinkin bout gettin it)

[Marlon_JB2]

It's the 3rd version of CDMA. I think it means Evolution-Data Optimized

[simpsonsadict]

i thought it meant evolution-data only. isnt sprint going straight to ev-dv evolution-data and voice. which would allow data transfer and voice service at the same time

[Marlon_JB2]

I verified it. It is Data Only. Oops.

Thats what I read as well.

[Mustang46L]

well, unfortunately at this point sprint is going to go to EV-DO before they get to EV-DV.. they are going with EV-DO Release "D" which is a relief because Release "C" is only actually EV-DO speeds down, not up..

EV-DV is the future of cell phones, and for most of us on this site can't get here soon enough but it will be time before we see EV-DV here in the US.

Sprint outlines EV-DO mobile data path
By Dan O'Shea

TelephonyOnline.com, Jun 22 2004

CHICAGO--Capping recent speculation that it was nearing a decision, Sprint announced at Supercomm 2004 this week that it will deploy CDMA 1X EV-DO as the next step in its nationwide mobile data evolution, with the potential to upgrade to EV-DO Release A or EV-DV technology in the next two to three years. While Sprint has long considered EV-DV as a potential next phase in its data strategy, the company also never ruled out deploying EV-DO, said Oliver Valente, vice president of technology development at Sprint's networks services division.

"We had always mentioned that we had the flexibility to deploy EV-DO first if competition and market demand necessitated it," Valente said, without referring specifically to the fact that competitor Verizon Wireless has begun a national EV-DO deployment. Still, many vendors and analysts have suggested in recent months that Sprint, in light of Verizon's plans, was re-assessing it previous idea of waiting for EV-DV, which likely will not be commercially viable until sometime in 2006.

Cingular Wireless also recently applied further competitive pressure. After announcing recently that it would test UMTS and HSDPA technology in Atlanta this summer, that carrier confirmed this week that it would deploy those technologies commercially next year.

Paul Reddick, vice president of business development at Sprint, added that Sprint also was driven to its EV-DO decision by the fact that its existing 1X RTT data network has posted significant usage in the last year. During 2003, the carrier recorded 20 million ringtone and screansaver downloads, and 5 million game downloads. Since just the third quarter last year, photo sharing via camera phone has grown 37%, Reddick said.

Valente declined to say which Sprint markets would get EV-DO first, but he said the technology will be available in select markets in the second half of 2004, and in the majority of large metropolitan markets next year. The carrier will use existing vendors Lucent Technologies, Nortel, Samsung and Motorola for the roll out. The deployment cost is covered in a $1 billion network investment commitment that Sprint discussed in it 2004 guidance earlier this year.

That $1 billion also will cover a future upgrade to either EV-DO Release A or EV-DV in the 2006 to 2007 timeframe, Valente said, adding that Sprint is still evaluating the potential of both technologiesm and has yet to make a decision.

The EV-DO deployment plan could be seen as something of a missed opportunity for Flarion Technologies and other providers of so-called 3G alternative technologies. Sprint confirmed it had been evaluating Flarion's solution as an alternative to EV-DO or EV-DV, but Valente said, "Sprint is not deploying Flarion. There were certainly attractive aspects to the technology, but we had some concerns about timing and equipment availability."

Valente also commented on Cingular's plan to eventually deploy HSDPA technology, which could support speeds in the neighborhood of 10 Mb/s, or more than four times the bandwidth of EV-DO. "HSDPA plans are aspirational more than they are realistic," he said, suggesting that equipment and handsets supporting the technology will not be available in commercial volumes anytime soon.

what does verizon have C or D?

[ImmerStark]

DATA AND VOICE:

cdma2000 1xrtt rel 0 is what we have now, 153kbps

cdma2000 1xrtt rel a is what we will not be getting, 307kbps

cdma2000 1xrtt rel b we will not get, it just has qos enhancements

cdma2000 1xev-dv rel c we will not get, it is the first version of ev-dv that supports 3.1mbps in the downlink, and 153kbps in the uplink.

cdma2000 1xev-dv rel d is what i hope we get, it is the second version of ev-dv that supports 3.1mbps in the downlink and 1.8mbps in the uplink

DATA ONLY (DATA OPTIMISED):

cdma2000 1xev-do rel 0 is what verizon and sprint are deploying, it supports 2.4mbps in the downlink and 153kbps in the uplink

cdma2000 1xev-do rel a is the next upgrade for ev-do, is brings speeds up to match those of ev-dv rel d. 3.1mbps down and 1.8mbps up

[SeminoleGrad]

Does the A700 support EV-DO already? And, if so, does anyone know about the "mythical" sanyo 5600, etc.?

hey man ya the vm4050 is the best phone ive ever had. the camera is awsome, video camera kinda sucks.(its a phone guys) the outside screen is nice, but the display is AMAZING. great great phone

[ready4URlink]

Uhh, I believe the EV-DV would have taken (and will probably) take Ready Link up a couple notches, and possibly outranking NEXTEL's iDEN Motorala/Direct Connect service. I'm confident that EV-DO will give ReadyLink more expedient speed than we have know. However I belive EV-DV was (is) in our best interest. Not that I'm not knocking our current system'; Hell, I'm married to Claire and Vision - I love em...

...but a far advance upgrade is needed to stay in an innovative position in the wireless industry.

Another good point, Sprint saw the threat of Verizon taking the lead and SPCS took deciscive action to compete with a newer version of EV-DO and slap VZW in the face. And I wish Cingular would step up, they'd get knocked right back down!
(Goooo Sprint!!)

[Rams29]

The Versions of EV_DO is dependent of the path a carrier selects. There is No noticable differences with the exception of equipment / Hiearchy. Most of us will not see the Upstream and Downstream speeds but will see a great improvement.

[Invader J]

Then it's all going to turn into EV-DVDA, the ultimate in 'interoperability' and 'high capacity' and we'll all go to hell.
