Simultaneous voice and data on Verizon / iPhone 5

[Anubis]

i asked in the ip5 thread but is this really an issue at all? i never at any time thought that i needed this feature

 

[ponyo]

Is there some technical issue preventing simultaneous voice and data? That's what I'm curious about.

Apple

from what i was reading earlier its because it basically requires 2 separate radios which many android phones have, ip5 is a all in 1 solution

It's the fact that simultaneous voice and data doesn't come in handy all that often. People make it seem like a huge issue, but it isn't.

So are you going to stop your conversation and start checking sports scores? Maybe you're on that con call you don't care about so sure, but when actually talking? Yeah let's see you read that email and carry out a conversation.

Oh so you want to call while you tether? Well I suppose then. But how many people tether anyway on an iPhone?

So, I don't get it.

In the other thread, you were all about how the GS3 sucks because it has 2 models, the US and international variant and that its fragmented because you want "ONE DEVICE", even though I'm pretty sure the US GS3 still works internationally, considering that people on XDA have been unlocking their phones for international use.

Meanwhile the iPhone 5 has, I believe 3, variants all unique to their area because of the chip, and when it gets reported that there are multiple SKU's each with their own radio, suddenly its not an issue. This was brought up to because you wanted international use, and even though international use is rare, this was a BIG DEAL to you.

Meanwhile, voice wtih data, which is actually very useful and used commonly, is available for the GS3 and many other phones on VZW LTE, but NOT on the iPhone is suddenly not useful and therefore not important?

Is there some sort of newletter I can subscribe to where I can figure out what are important features and what are not important features according to you? Also, can I get some sort of updates as to how you react to certain features that are not there?

Apple is literally retarded. I don't see how iFans can justify this.

because very people actually care/use this feature for $200 Alex

 

[Rayb]

I guess the term "multitasking" is still a term not well understood by some people.

 

[sswingle]

Ok, so they use one radio so you can't do LTE and voice at the same time, but why can't it drop to 3G data and voice like other phones have been able to do for more than a year now on verizons network?

[bearxor]

It sounds like, after reading, that the feature actually requires two separate antennas for that and Apple has decided to dedicate both antenna to voice diversity instead of splitting one off for data.

In the end, I don't think this will affect a LOT of people, but it's still a mistake. Was thinking of switching to Verizon or possibly Sprint, this will seal me staying on AT&T.

 

[Fingolfin269]

It's only a mistake if someone at Apple is slapping themselves in the forehead saying "OH MY GOD HOW DID THIS HAPPEN?!!!!". Yeah no. They know that most people couldn't care less.

You _DO_ realize that Verizon is as much to blame for this as Apple? You make a lot of outrageous and wrong claims against Apple, it's to the point that it is ridiculous how biased you are. I've refuted you on at least two ridiculous anti-Apple claims and you ignored my post because you know you are wrong.

For those with at least a shred of impartiality, most of the CDMA implementations in the USA do not allow simultaneous voice & data. This required two radios, one for voice, and one for data. This is a fault of CDMA and it is also Verizon's fault for using CDMA. This is not Samsung's fault. Not Google's. And most definitely not Apple's.

And this is not to imply CDMA is inferior, there were definitely advantages to using CDMA over GSM. There is also an update to CDMA which allowed both voice & data but wasn't enabled by Verizon until 2011.

Now, Apple has implemented a single chip for both CDMA and LTE. That means they are not using two radios (antenna design may play a part in this) so it can't access voice and data at the same time over Verizon's CDMA network. Obviously other phones have the two radios necessary for this functionality. For aesthetic as well as cost reasons, Apple is not going this route. Therefore, only either voice or data at one time. But as anyone who is impartial can see, this is as much Verizon's fault as it is Apple's.

From the perspective of Apple, most people (especially non-geeks) will use this feature. Is it nice? Definitely. Would I like it? Definitely. Will the average Joe miss it? Not likely. So Apple is not implementing a feature most people won't miss and saving a few bucks in the process. Sounds like a brilliant business decision to me even if it does suck for geeks and power users.

Pretty much everyone on WiMax or regular CDMA has the same constraint, I have yet to see it be an issue.Tmobile or ATT or someone was trying to use in their marketing with literally zero impact, as most people see it as a gimmick.

I don't think I've ever had a case where I would put someone on speakerphone to be able to google something; the closest thing would be switching to an open maps app or open browser window.

It's not a huge deal but big enough for AT&T to make a commercial promoting just this feature over the Verizon version of the iPhone a while ago.

I thought Sprint 4G wimax phones allowed data and voice.

 

[ponyo]

Why are you blaming Verizon? For using CDMA? SGS3 has no trouble on the same CDMA network.

Apple made the design and engineering decision. No one forced Apple. The blame lies solely on Apple.

You do realize the choice for CDMA was made loooooong before the iPhone was a glint in Steve's eye, right?

Yea Luke Wilson will get more $$$ for his commercials. So how come the HTC/Samsung LTE phones can do both data/voice simultaneously? I know they dedicated one of the antennas to voice and another to data but Apple dedicated both antennas to voice? Is this because of the lawsuits?

 

[akugami]

And this excuses Verizon for choosing CDMA? That's Apple's fault? Again, Verizon made their decision to choose CDMA with its advantages as well as disadvantages. Apple made their decision and will have to live with the advantages and disadvantages of said decision.

Make no mistake, Apple's decision does have both. It's not as stupid of a decision as Phokus makes it out to be. For one, improved battery life without having to power two cell radios. Another is reduced size and weight. For Apple, another positive is reduced cost even though this cost saving isn't passed down to consumers. Purely a business positive but when you run a business, you usually want to make a buck.

As far as negative goes, it's the inability to simultaneously use voice and data on Verizon or Sprint's network. Keeping in mind most people don't use voice & data simultaneously, this isn't as big of a deal as it originally sounds like.

 

[jersiq]

again, it was chosen a long time ago. so long, in fact 1x-rtt wasn't available yet. maximum was 14.4 kbps rate on a single CE. do you think that in 1998 timeframe you would have had the foresight that there would even be a smartphone market?

PS VZW didn't chose it. The regional operators that later formed VZW already chose CDMA.

 

[Bateluer]

Its part of the reality distortion field. Its a feature that few actually used, but most (iphone owners) raved about when most decent Android phones with 3G only Verizon devices. When the first LTE devices arrived, and could do data&voice, it wasn't an important feature any more and something that was barely used.

With the iPhone 5, its an irrelevant feature. When the iPhone 5S arrives and has data/voice, then it'll be important again.

this was because qualcomm obviously had some under the table shady crap going on. they tried this in other countries like brazil, canada, etc, which all abandoned cdma in going to 3G networks and went for HSDPA. in fact they deployed 3G so well that by 2010 they were using GSM phones with no CDMA fallback at all.

Verizon had a choice to move to UMTS. But no.

AHAHAHAHAHAHAHAHAHAHAAHAHAHAHAHAHAH, ARE YOU SHITTING ME? How the HELL can you blame verizon and defend Apple for this? Apple KNOWS how the technology works, it's been that way for a LONG time! It's not like Apple was blindsided by this.

Oh my god, this defense of the indenfensible by you iFans is becoming ridiculous (if it wasn't already).

Ad hominem attacks such as 'iFans' is barred as outlined in the sticky at the top of the forum.
This is your first and last warning.

So to enable simultaneous LTE data and 1x OR GSM voice phones have been built with two RF chains that can be run simultaneously (note this is not two baseband processors, just the analog)

There are however other ways to do this...

 

[Aikouka]

Here's an article from Anandtech on it:

For those that care: Simultaneous voice and data might not be important to some people, but it is important to me. I check movie times, do searches (based on questions that come up during conversation), check for restaurants, check email, check the weather, check product specs etc. while talking on speaker phone or using a headset. Is all of this necessary? No. Do I enjoy doing it? Yes.

I am currently an unhappy AT&T subscriber, and I was looking forward to the move to Verizon. I now have another thing to consider before I make the switch.
