More fuel for UMTS vs. EV-DO

jinx7676

Sep 27, 2005, 11:31 AM
i haven't heard this fact mentioned anywhere.

UMTS allows for simultaneous Voice and Data transmission, whereas EV-DO is "Data Only" (hence the "DO", so if i assume correctly, if someone is using their EV-DO device for internet applications, they wouldn't be able to recieve a voice call. Just another thing to think about... 😉

but the question i have is when will that revision roll out? i mean i would think they would want to build the infrastructure first, then roll out upgrades. meaning for the time being, UMTS will have the advantage until that revision is implemented.

rev o is being deployed as we speak by sprint and verizon, rev a will probably be on the networks by late 06 early 07.

here is a website about comparing between ev-do and umts its quite interesting.

Not a hope that they'll have HSDPA out by year's end? They are launching the HSDPA upgrade in tandem with their UMTS deployment. That means HSDPA will be in about 30 markets by Christmas. Even more in the following months.

You are correct. EV-DO is for data only, but Verizon is adding to the network and has plans for their EV-DV network to be running (at a time in the future, when? I have no clue).

Sep 28, 2005, 3:05 PM
I shouldn't say it has been dropped altogether, but rather development has been suspended. The reason being that EV-DO rev. A is faster than EV-DV and it retains backward compatability with EV-DO rev. O and what not. The point is, EV-DV has no viable future and won't be accepted by copmanies in the future.

First off, is a personal attack the proper way to answer an honest question? I don't think it is.

I didn't know because I misunderstood a huge piece of the puzzle:

I was under the impression that Rev A was EVDV. I have since been informed correctly by someone who doesn't feel the need to ridicule everything someone says.

Thank you.

rev a isnt ev-dv. rev a is an upgrade from ev-do REV O. REV A has been enhanced, thanks to my qualcomm, with voip and that is why ev-dv isnt needed.

Ruff, seems like your stalking me (jk). If I read your link correctly, the EVDV is being scrapped because EVDO is already in use and they plan on revising the current system to effectively be like what EVDV was going to be. Is this a correct assumption?

Vox Dei

Sep 28, 2005, 6:00 PM
EV-DV was designed to take EV-DO and enchance the origional 1xRTT voice system. The thing is with EV-DO's rev A lagnecy rate is so low that they are planning on just using VoIP instead and getting rid of the voice system completely eventually. This will cut the costs for the carrier drasticly because they will no longer be reliant on land lines.

I don't believe that they manufacture entire phones, but they do have proprietary technology on just about everything that you put in a phone. They've recently bought out screen manufacturers, antenna manufacturers, anything you can think of. And of course, they also make CDMA and UMTS chipsets.

Ah... so, basically, Qualcomm are the puppet master of the wireless industry. Interesting. What if they were to fall tomorrow (just speculate), what would happen to the wireless industry, I wonder...? Food for thought.
...
RUFF1415

Oct 3, 2005, 7:06 PM
Quite simply, it would never happen.

If they did, there are thousands of other companies that still produce the components of phones to keep phone industry working smoothly. Texas Instruments produces phone chipsets, for example. The fall of Qualcomm wouldn't do much to affect the GSM side of the industry, because Qualcomm's forte is with CDMA.

But once again, it would never happen.

if qualcomm or TI (texas instruments) went chapter 11 we would have to say good bye to all phones, however, as ruff said it wouldnt happen. the amount of cash flow they both generate and the huge patent portfolio and r&D spending that they have and will have in the future will prevent chapter 11.

what ifs are always nice to examine though.

Yes, it's interesting to see that we take something for acquired and never wonder what it would be if we were to lose it. I could ramble on, but this has nothing to do with Cingular, so I'll stop there. Would be a good topic to pursue in the Lounge forum, though.

Anyways, back to UMTS. I look foward to it. Why am I saying this when it has begun to be deployed? Well, up in Canada, EDGE is still in it's infant stages. And yes, this is not a joke.

yea, we can take this to the lounge or to tech but even though this has nothing to do with cingular, it does have to do with ev-do and umts becuase both qualcomm and ti helps supply chipsets to make these things possible....

whoever started this thread probably shouldnt have put it here, but its ok i guess.

yea, i like talking about this stuff it is quite interesting.

actually it has to deal with cingular becuase with out qcom and txn cingular wont get umts/hsdpa. 🙂

SAN FRANCISCO-Cingular Wireless L.L.C. provided another round of updates on the progress it is making in integrating the former AT&T Wireless Services Inc. operations. An executive Wednesday said the integration is still on track to be completed in 2007.
"We are entering into the most critical phase of the integration process," Mathy said, adding that the carrier was moving from "13 good networks" toward "four great ones."


Cingular noted that significant progress has been made on integrating the GSM operations, which after the merger included 63 overlapping markets. Mathy said the carrier would have 35 of those overlapped markets completely integrated by the end of the year and that some...

Well technically they're both CDMA. Although UMTS is based on the core GSM technology, it is overlayed with the coded-air interface of true CDMA, hence the interchangable term WCDMA. Both technologies will have similar voice quality, signal penetration, coverage reach, and call capacity for that reason. It's the speed of data where they differ. And that is where UMTS beats EVDO.

Oct 2, 2005, 5:04 PM
It's true that the commodity of SIM cards gives UMTS the advantage, but then again, it's just a matter of preference. For buisness users or people who change phones frequently, then UMTS seems the better option to consider. But for those who use a phone till the day of it's death, then CDMA is viable too.

Just like I said, it's a question of preference. I prefer CDMA (which I have been using for one year now), and I have used GSM before. When I first had my phone, the quality of CDMA left me breathless. But I am not closed-mind to UMTS, on the contrary. I simply prefer to let time run, and hear feedback from people using UMTS. If I hear good things about it, then I will consider UMTS as another option when my LG VX-3200's time in this wor...

You understand that UMTS uses 5 Mhz of bandwith were EV-DO is 1.5 Mhz. EV-DO has 3 times the capacity because of this (its slightly less than this because each channel is slightly less capacity than the UMTS 5 Mhz channel). Hsdpa is only high speed download and uses regular UMTS for upload (which is slower than EV-DO. UMTS does have better penetration into building and such which is it's main advantage over EV-DO and it's lagnicy is slightly better than EV-DO rev 0 (but loses that advantage when rev A comes out).
