This would be a make it or break it buying decision for me but I don't see why the chip wouldn't support SVDO. How soon before the Keynote speech is normally uploaded to the apple site ?
 
Let's be clear here.

voice + data over 4G LTE was a chip issue, not network.

where as,

voice + data over 3G CDMA was a network issue, not chip.

The iPhone 5 page says it support EV-DO rev a and rev b, not SV-DO, so we will have to see what it turns out to be. :apple:

SVDO is a chip thing. It simply means there is an additional chip present to offset (or circumvent, as stated previously) the CDMA network's limitation.

If someone can answer any one of my 3 questions posted previously, collectively as a group we might be able to get to the bottom of this.

I especially need to know what the "single radio" is and what it does.
 
Let's be precise here, please. It seems you have some specific knowledge about the hardware, can you please answer each of my questions individually.

I'm not quite sure, I haven't actually looked *too* deep at the iPhone 5 yet to see how its networking is fully laid out. I was at work during the keynote and plan to watch the video of it tonight when Apple releases it. I can say that generally with Apple, if they don't emphasize something, then that probably means it doesn't have it. So most likely you will only be able to use voice + data at the same time on LTE. Lets be honest though... this feature probably won't be used that often, and Verizon's LTE network is SOOO much larger than its rivals that it is a very worthy trade off, in my opinion.
 
Indeed it does, very few phones actually use SVDO (only 1 I can think of off the top of my head is Thunderbolt)

HTC Thunderbolt
HTC Rezound
HTC Incredible 4G
Samsung Galaxy S3
HTC Evo LTE
LG Viper

----------

348SStb, whether on LTE or on EV/DO for data (4G and 3G respectively), the phone call is placed over 1xRTT, aka 2G. This is true whether or not it supports SVDO (it's just that without SVDO, on a phone like the Samsung Galaxy Nexus) it isn't able to hold a call on 1xRTT while holding a data session on EV/DO, though it can on LTE.

Right, thank you.

Perhaps you could shed some light on what the "single radio" is that Apple spoke about? What is it and what does it do?
 
this is a great idea for a thread and I was shocked that the one from last night got moved
 
No idea. The Galaxy S3 and others use the Qualcomm Snapdragon S4, which is a CPU, GPU, and radio all in one component, I believe. Saves size, reduces heat, uses less power. The more recent devices that support SVDO all have the S4 in 'em.

Thank you, Rolltide. I doubt anyone will ever tell me why mine got locked and tossed into the abyss.

It's very interesting that there are very few discussions about this on the internet right now.

I am wondering if the "single radio" is dedicated simply to non-LTE data whereas the the "single chip" that handles "voice and data" always handles voice and sometimes handles LTE data.
 
I don't know, man. I am curious to see how this shakes out. Useful feature, wish more phones had it.

Me too. I buy a new iPhone every time one comes out. I don't care about the money. These are the things I spend money on.

That said, I have been disappointed that Apple always insists on marching to its own beat without watching what the competitors do. Apple looks at the available technology and tries to make its own product - it's almost as though Apple makes the product in a vacuum without ever trying to outdo what the competition has done.

Cases in point:
1) iPhone cameras are and have been a joke next to Android handset cameras. This is not debateable. They don't try to match or exceed.
2) iPhone could easily have kept its 4S form factor while using the freed up space to:
i) knock battery life out of the park
ii) add an additional chip so that the phone could support all bands and thus be a one-phone only offering (instead of the fragmented CDMA or GSM offering we have here)
iii) add an additional chip to support SVDO
iv) add an additional LED flash
v) make the camera lens bigger, better, and higher in megapixel count
vi) make the screen intensely bright and snappy as in Samsung Galaxy S III...

...And the list goes on!

That's why we just may not have SVDO!
 
Luckily I live in an area blanketed in Vzw 4g LTE so svdo won't matter much but it would have been nice to have it when visiting rural areas. With all of the changes this may be the first iPhone that I keep for more than one year unless the iPhone 6 is truly ground breaking.
 
I own a Nexus. It does not support SVDO and will not hold a phone call at the same time as an EV/DO data session. You are, respectfully, mistaken.
 
wow, there was a lot of misinformation on this thread.
The people that say that SVDO is an on-device implementation are correct, those that say otherwise are not.

Also, a very easy way to determine this is to simply observe the chipset that currently supports SVDO and LTE within the same chip. The Qualcomm mdm9600 is what is currently used in LTE handsets (and the iPad), the only difference being in the radio that it is paired with to determine the frequencies.
The iPhone uses the 9615 (as evidenced in logic board leak), which also supports SVDO.
 
Preed, that is very, very interesting indeed.

I imagine my failed attempts to raise awareness of SVDO will become more interesting if this is true.
 
I too am very surprised that there isn't a lot of discussions about this yet. I've been wanting to switch to Verizon ever since they got the iPhone and I actually did it on the 4s but ended up returning it. The dealbreaker was the surf and talk, multiple calls or conference calls (doesn't show who you're talking to, and when you dump 1 line they both go away and the person holding rings back as 'unknown caller') and the 3G speed sucked compared to AT&T suedo 4g. To my surprise what I just listed here mostly nobody talks about including Verizon they don't even seem to know about these limitations. For what it's worth I called the Verizon store locally today and they
told me all of their 4G phones support surf and talk and the multiple caller thing they weren't sure. IMO if it does, the playing field is Finally even and I'm surprised apple or the carriers aren't mentioning this....yet. Remember those AT&T commercial saying only network that allows surf and talk on the iPhone? Lte on Verizon is a no brainier spanks everyone else as far as deployment.
