I think it would help some of the less techy guys here if someone who is knowledgeable in engineering to explain via diagram why CDMA is so different from GSM. It's hard for me to wrap my head around what appears to be an assumption that a CDMA chip/antenna is different enough from GSM that it cannot be swapped out in any cell phone application. Is it the coding of the chip, is the chip and antenna that much bigger?


Manufacters made their products both ways all the time. Look at the Motorola Rzr line. CDMA and GSM!

The thing is though the iPhone has been sold all over the world GSM only! And most parts of the world are GSM only. The difference in the two are the way they pack their data to transmit voice etc.

CDMA is a technology from the WWII days. GSM is around 1991 I believe. SO .... Does Apple want to make phones for Verizon Metro PCS and third world countries running CDMA .... Only they can decide.
 
Interesting

First, the rumor could be wrong. However, I often believe that, regardless of the arguments played out in the media, if it makes sense for both companies (verizon and apple) to make a deal, they'll do it.

Second, I still believe that a verizon iphone will put a ton of pressure on the other smartphone startups, if they go head-to-head. It could theoretically marginalize the android's market share into that of the zune within 24 months.

Third, maybe apple didn't WANT to have to create a verizon iphone, but the quickly growing android market share forced apple's move.

Fourth, do you think that apple could be releasing a phone for each of the top three carriers, not just verizon?
 
Verizon sells a number of "world phones" with both GSM and CDMA radios, so it's really not a big deal.

The Qualcomm "Gobi" chip supports most of the major radio standards, plus has assisted GPS on the radio chip. The only issue of note is dealing with antenna design for the different frequencies.
Do those Verizon "world phones" do both voice and data, or just voice?

How are power requirements on the "Gobi" chip? Apple is already struggling to get battery life out of their current iPhones (it's one of hardware shortcomings most often mentioned by iPhone owners).
 
at this point I just don't know anymore... We'll see what happens at WWDC. Hope the one more thing will be "we have some Very big news :rolleyes:
 
As far as production goes, would this not be a whole lot different from producing both WiFi iPads and 3G iPads? And yet, they're doing that...whats so crazy about producing both CDMA phones and GSM phones?
 
...whats so crazy about producing both CDMA phones and GSM phones?
There's nothing technically crazy about producing both CDMA and GSM phones, it's more about what sort of return Apple would get by doing both. GSM dominates the world cellular market (about 70%). The CDMA market is far smaller. Even though China uses CDMA, the smartphone market is still in its infancy there. Most Chinese can't afford $200 smartphones and $80-100 monthly mobile subscriptions so the revenue potential for Apple is still very limited at this time in China.

There are costs associated with designing, building, selling, and supporting a CDMA iPhone. Will projected sales of a CDMA phone justify those costs? Only Apple knows and it's their decision.

Apple prefers to maintain high profit margins on its hardware sales, and as an AAPL shareholder, I don't want them eroding their margins with something that simply doesn't bring a lot of revenue.

Apple's primary mission (like that of any publicly traded corporation) is to increase shareholder value. It's up to Apple senior management to decide whether or not building a CDMA iPhone will do that.

Frankly, I'm not convinced that a CDMA iPhone at this time would do that. Perhaps in a year or two. As an AAPL shareholder, I would love to be proven wrong though. :D
 
I find the posts that say "Verizon iPhone will never happen!" a little funny. Really? What do you know? Nothing more than the next guy...

IF and only if iPhone does come to Verizon, I will be happy because I wouldn't have to switch carriers after 7 years of good service. I will be getting this iPhone regardless of which carrier does or does not get it.
I'd be interested in seeing what kind of differences there would be in the CDMA iPhone. I have seen a trend with Verizon phones in the past that they limit a lot of capabilities on their phones. That trend seemed to progressive start to change with the Droid. I just don't know how Verizon would be ok with the fact that one of their devices would not be branded with bull$#it vzw crap and use iTunes only. Not only that but Verizon makes a killing off of their insurance policy...but now people would be buying Apple Care?

I'm definitely intrigued as to whether or not there will be a CDMA iPhone and I do think there will be. I however...am more excited for it to come out and to get it regardless.
 
It baffles me how the Largest carrier in the US, uses the most outdated form of wireless.

Because "yes, I can hear you now".... :D


Not only that but Verizon makes a killing off of their insurance policy...but now people would be buying Apple Care?

I didn't think that insurance was available with an AT&T Iphone. No Applecare, no insurance.

By the way, I made a "killing" on my Vzw insurance. Knocked my touch-screen smart phone out of the holster, it fell face down onto the concrete garage floor. Beautiful spider-web shattering of the LCD glass.

Replaced, no questions.
 
I'll believe it when I see it. It'd be funny if Jobs announces they're releasing a CDMA phone . . . for China.
Of course, my friend who switched to Sprint from Verizon would be pissed. She doesn't like AT&T, but likes the iPhone. Hence, she got an iPod touch.
Personally, I'm good with AT&T's service, so it doesn't matter to me about the possibility of a CDMA phone.
 
Depends on how fast users join Verizon. I suspect for a few months or even a year Verizon users would legitimately claim a faster, non-bogged-down network. But eventually capacity will be hit because it is economically unwise to build too much capacity ahead of demand.

If a significant number of current AT&T customers switch to Verizon at a rate faster than new customers joining AT&T, then maybe the AT&T network will clear-up and become faster for those sticking around!

FWIW: I don't have problems with AT&T in the East Bay of the SF Bay Area. It's fine for me, even under the bay on BART.

the point is that it'll still happen.
 
Why would Apple make a CDMA phone? it cant do any multimedia functions that the iPhone is touted for.
Actually a network having CDMA in todays time is a joke.
I guess as they say "Only in America"

What? What multimedia functions would have anything to do with the wireless radio technology? Can't play videos? Can't play music? Can't stream music? Nope...it'll be able to do all of these things.

And GSM is older than CDMA....so what exactly makes it a joke in "today's time?"

I can see the commercial now. . .

"You can't surf the web at the same time. . . but It's on the nations better network" iPhone HD Now on Verizon

So lame. . . I don't buy these Verizon rumors simply because the iPhone, in America, doesn't need Verizon to still be successful.

GIVE IT UP!
Why would Apple waste money to produce a CDMA phone JUST FOR ONE CARRIER? Not going to happen. Give it a rest already.

All of the Android outselling iPhone headlines would seem to conflict with your statement.

13" mac book pro? nope, er, wait, hmm......

Thinner with a faster proccessor? Um... Doesn't most tech follow the smaller and faster route? That sounds like a prediction my grandmother could make.

Except the 3G was thicker.

However, some only see the advantage for Verizon which is far from the case. IF Apple would produce a CDMA phone I doubt it'll just be for Verizon in America.

Beside, GSM is the most popular for mobile around the world. So in my opinion making a CDMA device would be kind of like a step backwards.

As I mentioned above, CDMA is actually newer than GSM so I don't see it as a step backward. It is generally accepted as having superior voice quality over the TDMA based GSM the US used until recently.

There are 522 million CDMA users worldwide. A majority are in Asia Pacific

Apple isn't everyone else though, they don't NEED to make one. That's not my point anyways. It wouldn't be JUST for Verizon if they decided to go down this route. Once Verizon gets the okay so will Sprint and other CDMA carriers in America.

As well as other CDMA carriers worldwide.

I think they are probably willing to accept a loss with the CDMA iPhone. By having a phone on Verizon they will be able to compete with the Droid on it's own carrier...I believe that will seriously help take some wind out of the Droid's sail.
 
Verizon Iphone

Look, if there will EVER be an LTE iphone that works on Verizon then Apple is going to HAVE TO put a CDMA chip in it to fall back on when there is no 4g coverage. They may have decided, let's get to work on CDMA now so when LTE is ready in the next 12-18 months (like when the 2011 Iphone is ready), they'll already have a year of CDMA testing (using real live users.)
 
Well one thing that was in the way of the iPhone going to verizon was the selling of music be it v cast or iTunes. So that might play a role in this but we shall wIt and see wwdc 2010

As a longtime AAPL shareholder and someone who reads their SEC filings, I do not believe that Apple would be willing to build the CDMA iPhone as a loss-leader. They might have during the era when Steve Jobs was not CEO, but not today.

Most likely, they would wait until the market conditions were right before launching into CDMA iPhone production.

Apple is all about high profit margins. If they dumped money down the drain, they would feel the heat from their shareholders. The big institutional investors and mutual fund managers (about three-quarters of the float) really don't give a rat's arse about Verizon having an iPhone if Apple's profit margins erode.
 
Lots of people seen to have theyre doubts. In all honesty your just going to I've to wait and see what really happens. Could be a toss up. If verizon does get the iPhone great for them. Business for them will skyrocket. If not oh well, I'm good with AT&T anyways I rarely ever get a dropped signal unless I'm in an elevator in the city building and what not. That's am exception I wouldn't be expecting service in an elevator anyways. I do know that most likely when AT&T stops carrying the iPhone I will be going to whichever carrier is most likely.
 
Verizon iPhone - NOT GONNA HAPPEN

Will be funny to watch you eat those words.

CDMA is a technology from the WWII days. GSM is around 1991 I believe. SO .... Does Apple want to make phones for Verizon Metro PCS and third world countries running CDMA .... Only they can decide.

That's a misleading statement. The concept behind Code Division is from WWII. But the actual IS-95 technology standard is from 1995 (GSM 1990) and that was just the first itteration. We are now on EVDO Rev A which is the 4th generation IIRC. It is by no means outdated.

And these other countries that use CDMA are not "Third World". China, Hong Kong, Japan, South Korea.....definately NOT third world.
 
I didn't think that insurance was available with an AT&T Iphone. No Applecare, no insurance.

http://www.apple.com/support/products/iphone.html

I took the 5-7 bucks I would have been spending on phone insurance and put it in the bank. I have never broke or lost my phone so I haven't had to use it anyway...but if I did I'd probably just buy a used phone to replace it. I know...not so easy if it was an expensive smartphone. I just think that the phone insurance is a gamble that I'd rather not take. I just try to be careful with the phone and keep it protected.
 
Verizon Iphone

If true and the Iphone Comes to Verizon. Iam jumping ship tired of the coverage in south new jersey 90% of the time my iphone 3gs is on the edge network if i wanted to be on the edge network i would have bought a regular flip phone. i can care less about talking on the iphone while surfing the net at&t:) just hope it supports verizons LTE network
