Qualcomm Suspends EV-DV Development

thanks for the explanation.

in your opinion, was it a bad idea that qualcomm is stopping production of EV-DV? what do you think will beat out EV-DO Both REvisions? (wimax and flarion)

thanks....

My pleasure!

No. It was simply realistic. I don't think anyone really made a mistake, it's just the way things worked out. If EV-DO rA hadn't come out, or Sprint hadn't changed its mind about skipping EV-DO, then we'd be in a different boat right now. Really, it was Sprint deciding not to wait for EV-DV that put the final nail in its coffin. After that, Qualcomm didn't have much of a choice - the market for EV-DV simply evaporated.

Nokia and TI are in the same boat. Worse, actually, because they bet everything on EV-DV, skipping EV-DO completely. They lo...

Great info. I just happened to see a slideshow updating information regarding the Sprint|Nextel merger and in the presentation it showed a time table of events happening over the course of 3 years and in it was Deploy PTT on EV-EV network by 2008. This was going in contradiction to what is being discussed here which is no plans for EV-DV. Does this mean that Sprint is deciding on backing away from EV-DV? I mean I know Sprint originally wanted to deploy EV-DV versus EV-DO but Verizon beat them into deploying a 3G CDMA network (EV-DO) in major markets. Now Sprint wants to catch up and decided on deploying EV-DO before upgrading to EV-DV therefore being ahead of Verizon in the end after deploying a nationwide EV-DV. Does that mean that this wo...

It's interesting to hear that Sprint is still looking at EV-DV, but I can assure you those plans are still tentative at best. They still have to finish rolling out EV-DO r0, and then upgrade to rA.

Who knows what the landscape will look like by that time? With Verizon talking seriously about moving everything to all-IP over EV-DO... if an industry standard emerges for that kind of thing, then that will certainly be a tempting alternative to EV-DV, when the time comes.

What Sprint has talked about publicly is unifying Sprint and Nextel on an EV-DO rA network, including PTT (presumably based on QChat). I have a hard time believing they would roll out EV-DO rA and not do the major Nextel transition at the same time. Waiting for EV-DV woul...

Yeah well this update was published 2-10-05 which was before the news release about Qualcomm so it could mean that they decided to opt out of EV-DV although that would be weird. I checked out the PDF file again just to make sure my information was correct. The timetable is as follows:

2005: Complete phase 1 EV-DO deployment.
2005-2007: Invest in iDEN network until voice traffic can be supported on CDMA network.
2005-2008: Rapid coverage ehancement through use of Nextel sites and spectrum.
2006-2007: Complete 100% overlay of EV-DO Rev. A and Deploy CDMA-iDEN Interoperability.
Mid 2007-2008: Maintain iDEN for Push-to-Talk centric customers.
2008: Launch PTT service on EV-DO Rev. A

very true sir. excellent analysis. yea verizon is using REV O. i dont belive verizon has an option to go to REV A, but i am not sure. sprint is going to do REV O then upgrade to REV A and then roll out Qchat, if in fact this merger gets approved.

from now till 2007 there will be dual mode phones, iden and cdma. also qualcomm, nextel and motorola are working on a gateway so that cdma push to talk would work well with iden's push to talk. ( i belive that is seperate from qchat)

hope that helps...

Thanks for the information. I figured they would try to develop some sort of gateway to get these to interoperate with each other. It makes total sense. I think this may be why Sprint never really advertized ReadyLink. There had been talks about Sprint possibly mergin with Nextel for some time now and although its natural to compete they weren't one to show off a product all over TV especially if they would eventually merge with Nextel and release a new PTT on its EV-DO network powered by Qualcomms QChat which Nextel bought the rights to a while back because they knew that they eventually needed to move on from iDEN and CDMA seemed like a good direction to go so they bought the rights to QChat before anyone like Verizon or Sprint did but aft...

well done. you are a very knowledgable person. any questions or concerns just dont hesitate to ask.

Thank you. I was hoping Rich Brome gave me a few pointers on how to get in the industry and what college majors to pursue since I am still debating on what path to head into. I like technology and I particularly like this type of technology dealing with communications and wireless data and that sort of thing. I don't know if I want to be an engineer but I would love to be an analyst or journalist or a product tester of some sort. I like to read and that's how I get my information. Sometimes I don't know if its right but most of the times it has proven to be correct. If anyone out there has any tips or suggestions on what I should do I would greatly appreciate it. Thanks a lot. Do you know when the PTT gateway is expected to be ready?

yea, technology is very fun. i was actually thinking of doing that (going to an engineering school or a school like ITT tech or something of that sort) after i get my bach's degree then i might go for my masters. not quite sure yet, becuase i am only 21. (i major in business mgmt and double minors in accounting/finance and marketing. )

thats why i love being so young, i have many options to do for my future.


well, you can be whatever you want to be as long as you work hard at what you are doing and set goals for yourself.

Psst. Skippy. Engineering school and ITT are two TOTALLY different things.

Another newsflash...everybody loves or loved being young.

i do, however, since i have ties to nextel and sprint i cant really disclose that information, unfort. see thats the problem with having ties to companies, becuase you cant discuss anything thats not published. and i am not sure if this site is monitored by the sec, ftc, fcc and other regulatory organizations that is why i am very careful with what i say.

no you idiot. it means that somethings you cant talk about unless its public. have you ever thought of that? i guess you dont have ties with a publicly traded company. there are things called disclosures and things of that nature. you can not tell things that arent listed. hence insider trading and things like that.....

Yeah technology is lots of fun. I am currently 20 and my major is Business Management with a minor in Accounting/Finance. We are on the same boat somewhat. I want to get into the business but still unsure as to what area in particular. It interests me which is good cause I don't want to spend the rest of my life in a job where I am bored and the slightest bit interested in what I do. I use to have both ties to Sprint and Nextel not anymore. Wish I still did. I might try to get myself back in. By your name im assuming your carrier is Nextel. I am Sprint here. We should chat sometime. Thanks for the info.

yea i have nextel for 6 years now, and actually prior to nextel i had sprint for 3 years. unfort sprint and i left on a bad terms, however, i did like their data speeds and content, but didnt like their customer service as well as other things. (coverage was pretty decent, but not better then nextel's)

In regards to Verizon taking everything to all-IP over EV-DO. Is that meaning to basically use the data spectrum for everything meaning turning voice to essentially VoIP? I guess that makes sense. I guess it would be easier but will it be as reliable? Isn't Sprint looking at something similar? Weren't they talking about WiMAX? I know Nextel was looking into Flarion but since the merger I think they dropped it due to Sprint's EV-DO plans. If you could elaborate on the speculations I would really appreciate it. Thanks Rich.

well said rich. the latest that i have heard is that sprint doesnt want to do DV anymore, but deploy wimax over their DO system.

have you heard differently?


yea qchat will be used on the DO REV A network in 2007. i belive if i remember correctly that about half of nextel's iden towers will be transofrmed into cdma towers by 2008 so thats a pretty good step. we have to hope and same with nextel that qchat will entice their customer base by going with sprint/nextel. i belive they will, but we shall see. i dont think that verizon or any of the other push to talk offerings will even effect nextel/sprint when they are combined. 2007 will be a great big push with the transition and qchat. it shall be interesting and i cant wait.

very true sir, and i thank you for your sound opinions.

" WiMax is no shape to replace anything yet. And Flarion's technology is good, but not yet proven for voice, and it isn't an industry standard. "

when you said that, i am feeling that you might be wrong, even though Wimax and flarion isnt really "out there" if thats the correct wording to use. however, i belive more providers worldwide are starting to test these technologies, that i belive that it could hurt ev-do. becuase when i compare the speeds, latency, and coverage areas to wimax and flarion to ev-do flarion and wimax destroys DO in every way. i guess the problems with wimax and flarion is becuase its not "out there" and that no one really knows how much it would cost.

...
(continues)

Actually, Flarion was available from Nextel in the Research Triangle Park (Raleigh/Durham/Chapel Hill) area, NC for about a year (though it appears that they recently cancelled it, probably due to the Sprint merger), and the reviews were almost universally positive. Still a bit of information here:
http://www.nextelbroadband.com/ab_home.html »

i know about the whole situation with nextel and flarion. but what i am saying is that they could always go back to it and/or go to wimax. it can be cancled for now, but later on they could always launch it over their DO system.

The thing about WiMax is that it's not designed to be mobile. There is a version of WiMax supposedly in the works to address this, but it's not anywhere near ready for market, from what I understand.

Mobile makes all the difference. A fixed wireless standard (assuming the antennas are fixed and don't move) is easy, but when you make it mobile, you have to deal with handoffs, Doppler effect, changing terrain, etc. That gets really complicated, really quick. WiMax just wasn't designed for that, and it's not the kind of thing you can just "tack on" as an afterthought (although some people seem to be trying anyway).

Flarion's Flash-OFDM is more mature, but it's still a proprietary technology, with no proven track record for voice. I think ...

very true thanks....


"WiMax just wasn't designed for that, and it's not the kind of thing you can just "tack on" as an afterthought (although some people seem to be trying anyway)."

yea, sprint is trying that actually.

i agree with your assumptions with flarion's ofdm.


we will have to see. it shall be interesting.


" think it's still worth testing, but I wouldn't expect it to overtake the existing 3G standards overnight. "

thats true. but what about in a few years? lets say in 2008 or 2009 maybe. do you think that wimax and flarion would hurt DO? do you think other providers domestically, here in the USA, and worldwide, which is more important becuase of people, will choose wimax and flarion over DO? (or is it just...
