So I was thinking about the tbolt, and realized something that I believe is interesting:
It's pretty common knowledge that Verizon CDMA does not currently support simultaneous voice/data, a huge grievance for many a verizon iPhone owner. The Thunderbolt is touted to be the first device that can handle this function and will do so by handling voice over the CDMA network and data over the LTE network. Makes sense, sounds good and all right? BUT....I was thinking about coverage of LTE and how it's pretty scarce for now and was wondering what would happen if you were not in an LTE area and using the Tbolt? Wouldn't the absence of the LTE network effectively stifle your ability to use data while on the phone?
Does anyone have any info on this or remember reading anything about it? It seems to me that it is entirely possible that the Tbolt will have the same limitations over simultaneous voice/data as the iPhone and other smartphones as long as the user is in a non-4G/LTE area. I am lucky enough to live in a 4G/LTE area so this wouldn't be a huge factor I guess but some people were really looking forward to having that capability.
Unlike all the rumors, the phones has two radios.
1 - 1x voice/data radio
2 - EVDO / LTE radio
The phone will do simultaneous voice and data in both 4G and 3G areas. Only issues is that two radios means increased battery drain

Your post makes no sense bud. The phone has the following specs:
CDMA 1X/EVDO Rev.A: 800/1900MHz
CDMA LTE - 700MHz
Rev A Capable
The phone has one of 2 possibilities:
1. In an area with no 4G coverage, the phone will simply not work as advertised. It will act just like any other 3G smartphone.
2. The more likely option, and I say likely mostly because they like to avoid class actions: Verizon partly delayed the phone in order to upgrade the towers and networks with the ability to process 3G data and calls simultaneously.

if that second option were true, wouldn't that mean that every phone currently running on 3G (iphones and droids alike) would all gain the ability to run simultaneous data and voice? that sounds very nice indeed.
i don't have any sources but i believe i remember reading that the nature of CDMA and how it connects prohibits simultaneous voice/data as opposed to however GSM operates. sorry for such broad information but i'm not exactly a wireless carrier expert. if what you said is true though and they found some way to upgrade it, that would be awesome for all those on verizon 3G.
my skeptical side though is saying that verizon is no saint and would just respond that simultaneous voice/data is a feature specifically for 4G service and if you aren't in a 4G area tough break and wait for 4G/LTE to roll out near you.
Actually VZW recently did a software upgrade for their infrastructure to allow simultaneous voice and data over EVDO Rev A and the Thunderbolt is their first handset with the radio capable of supporting it. From what I've read it's a hardware thing so they can't update firmware in other phones like the iPhone to support it. I can't link to any articles from the XDA App but read any of the major Android blogs as they've been reporting about it for the past couple days or do a Google search for SVDO.

BAAMM! lol
That is the rumor Verizon is not using 1X advanced, so the only way that simultaneous voice and data works if you have two radios which are capable of transmitting at the same time. This is why only select 4G phones support SVDO.
As I said earlier, SVDO will work in both 4G and 3G areas because of the dual radios on-board.

The Thunderbolt have SVDO support, because it's using a SVDO capable chipset. Dual radios doesn't have anything to do with it, but only with CDMA/ 4G LTE handoffs, which is similar to Sprint's 4G phones. SVDO works on a 1X and 1X Advanced capable device, so didn't need to switch to 1X Advanced in order for it to work, though they have been some 1X advanced codecs for a while. Verizon wanted this including in their iPhone 4 phones so bad, but it just wasn't ready.

Ok, so I was interested in checking out the LTE speeds and wanted to test out the ability to do SVDO. I went to my local Verizon store and realized that My area doesn't have 4G yet. Duh! lol. And when inspecting the phone itself I could not find a way to turn on or any mention of LTE in any way anywhere on the phone! Hmmmm. So then I tried to test SVDO. I called one t-bolt with the other display t-bolt and then tried to surf. Newp. no can do. The call went thru so Its all setup but maybe it had no sim card?? I didn't check. Maybe my area doesn't have SVDO yet either? Can anyone now confirm simultaneous voice and data??? Now that people have got the phone in their hands now.
I am not in a 4G area and I can confirm the phone does voice and data simultaneously, very well, I might add

You know my verizon rep said a funny thing today when I asked him about the voice/data at the same time on 3G...he actually said "we don't guarantee that will work yet and that the network is still being worked on in some places to enable this feature for certain devices like the Thunderbolt" I had already tried it on the demo TB so I wasn't worried but maybe that's why it's not working for you.
I can also confirm that in a non 4g area it does both voice and data at the same time... nice feature I didn't expect.
Hmm, yeah I guess as usual my area is slow at upgrading the network. Man, if Verizon would pay my etf on Sprint I would be all over that thing.

I work for verizon and you are right they have changed on the network side making simultanious voice and data through both 4G and 3G and it was done on the network not on the phone itself. Now I don't know if this was the reason for the month and a half delay or not but makes sense. From what I heard from my friend in the testing department it had to do with battery.
I don't know about you guys but I really love the fact that all the naysayers that simultaneous voice and data is impossible can finally shut up. LOL

i know this is gonna sound mean but it makes sense. if u lose 4g its not a smooth transition. so until it reconnects to either 3g or 4g u tech dont have any service
Unfortunately they are right. There needs to be a better setup as anything up to 3G runs on the same CDMA radio, so therefor it switches and forces a dropped call. 4g is a separate card and works on it's own. Until there is a way to get "just" calling and 4g (aka turning 1X 2g, and 3g off but not 4g) it will continue to do that. I assume custom ROMs will do this in time, but as of the moment it's a known issue that it happens. Sorry to hear it causes you and so many others troubles.

well.....you could go into that secret menu and just enable LTE radio. i dont remember what the code was tho
Your phone calls do not go through the 4G network so that actually would make no sense at all... Your phone routes calls through the standard radio all all data through the 4G radio (if available). If you do not have 4G coverage, the both voice and data are carried on the standard 3g signal. This is Verizon's first simultaneous data and voice over 3g (yes, cdma data and voice) and there are known issues with the tech right now. However these issues have zero to do with any phone using 4G for data while you're on a call. Hope that helps clarify.

That's what I'm trying to figure out. Unless it's poorly programmed, it should maintain the voice connection as that's over 1x and independent of LTE.

It's most likely the same problem that Pantech UML290 users are experiencing when dropping from 4G to 3G, and both devices are using the exact same Qualcomm MDM9600 chip. If you look at the Engineering Mode when the drop from 4G happens, your phone doesn't just fall back to 3G, but it actually lose the connectivity for a few seconds and then "redials" back into the data connection.
I hope they fix this real soon.
When you lose 4g, the data tries to resume on 3g, and since no 3g and calls at the some time, you get data on 3g and dropped call

That's incorrect.
you have to have CDMA service for a voice call. EVDO alone will not allow a voice call, LTE alone will not allow a voice call. you should be able to lose 3g and keep your call going, and you should be able to lose 4g and keep your call going.
Maybe that's their way of preventing talking while driving. lol.

It happens because both radios power down to meet SAR requirements. Two radios at full power = too much radiation

Sent from my ADR6400L using XDA App
SVDO uses two transmitters simultaneously for voice+data over 3g. EVO has been using 4g+voice over CDMA for a long time.
look at the last couple pages of this document
http://www.qualcomm.com/common/documents/articles/1X_Advanced_Benefits_050509.pdf
I don't know if simultaneous voice+data over 3g is only available where verizon has 1x advanced or not. since SVDO only requires the handset to have the capability, it would make sense that it could use regular 1x and evdo simultaneously but it would use more spectrum.

It is true.
Verizon says it is a limitation of their network system and that dropped calls will indeed happen when you leave a 4G zone. They have intentionally designed their network not to fall back onto CDMA when 4G is lost, and they hope their customers will be patient while they expand their 4G coverage - which is occurring at a very fast clip. See the following bit from CTIA this week:
However, Verizon has taken the view that it will minimize annoyances for users handing off between LTE and CDMA, because its LTE coverage will be so wide so quickly. For this reason, it is not bothering to invest in systems to support fallback to CDMA for voice calls when a customer moves out of an LTE zone. Although the call will break in this situation, it will be a rare occurrence, insists the cellco. CTO David Small reiterated the point at CTIA, saying: "At the velocity at which we are pushing LTE markets, this becomes a non issue."

Yeah it's really noticeable when you do something try to send a picture message while on the phone. The upload speed is just crazy low.
No throtling being done here. From my understanding during a phone call lte simply cannot be used in conjunction with voice calling, so the LTE radio is turned off and voice is sent over hspa+(or whatever other bands its using) and data switches to HSPA+. So not neccesarily intentional throttling per say, just hardware and technological limitations. Once VoLTE is more common practice I'm sure this will change.

That's not really true. If it were then the faster the connection you have, the faster your on call connection would be. If what you were saying was true then when I'm in an area that gets 9 megs during a call, I should get better on-call data speeds than if I was in an area with 2 megs. Instead regardless of if I'm in a 9 meg or 2 meg area, my data speeds during a call still instantly drop down to around 1 meg and the upload ALWAYS goes down to the 20k area (even if I'm in an area that gives me over 2 megs of upload. BTW, it wasn't always like this either. It isn't a limitation of technology, it's a limitation placed by AT&T, most likely to save spectrum. The crazy thing to me is they air these talk and surf commercials but you can barely do it now. If you compare it to Tmobile, it's like night and day.
I saw that the other day when I was on a call. Thought I was just in a bad area. Just tested on my coworkers note while he's on a call, same thing. Lame.

How is it a hardware and technology limitation if the SAME PHONES perform DIFFERENTLY on different networks using the same technology?
Ok some of you guys really need to research more about how AT&T's 4G lte network works lol,Lte is purely for data so when not on a call the phone will sit on the lte band but the moment you make or receive a call the network hands off the phone to a hspa, hspa+ or edge (connection if the other 2 3g connections hspa or hspa+ is not available) . Once the call is done the phone should switch back to the preferred lte connection. Currently not being able to make voice calls over lte is a limitation by the tech, once voice over ip is ready to be implemented on lte then we're good to go.
Sent from my SAMSUNG-SGH-I727 using xda premium
I can confirm this on my Note. I thought it was just an odd quirk for me but I'm partially glad to hear it affects everyone. On my old HSPA phone I could maintain 2-3 Gbps at home even while on a call - useful for work so I could be on a conference call while also remoting to my work computer's desktop. Now when I'm on a voice call the data connection becomes nearly useless. I may have to switch back to my old phone next time I need to do this - which is ridiculous!
So even if a phone call does force you onto HSPA, they are still throttling you far below the available bandwidth.

This issue has nothing to do with LTE though. I know I saw someone earlier in the thread bring it up, but that has no bearing on what we're experiencing.
I noticed the same thing as well last week when I would make calls. LTE shuts off, 4G kicks in for calls. Hang up, LTE turns back on. Just like Verizon's no data while talking its simply a hardware limitation on the network for now.

From what I've experienced it goes beyond just kicking you down to the HSPA network.
They definitely changed this. Tested this extensively when the skyrocket came out
The hardware is not capable of both seperate radios operating at the same time and voice over lte has not been implemented.
Plain and simple.
When you make a call the lte radio goes idle. The hspa (3g and hspa+) radio activates
Speeds during call should be the equivelant of speeds achieved with a 3g phone...like we confirmed with a gs2 Back then
Now though
Slow speeds while on a call
tested 3g speeds...added the phone apn and select it. It may or may not work but if it works it will lock you onto 3g briefly enough to do a speed test. Compare that to your in call tests. or use a 3g only phone To get a comparison test IN REAL TIME
Technically att could begin throttling but it could be network issues as well.

Perhaps YOU should do a little more research...I assure you I am not a ROOKIE when it comes to these things. I have known for a fact that people were able to surf and talk on AT&T's network in the past without any problems. Now internet is practically UNUSABLE while on a call. Pages wont even load. There is something very underhanded going on.
Even by your own statement the phone should revert to 3g speeds while a call is being placed so why are speeds equivalent to EDGE/Dial Up when people have adequate signal strenght?
Apparently some GNex users in Athens, GA have a live LTE tower... Let's hope this holds up...

Great question... With 4G, it didn't even feel like a mobile data connection... Hopefully LTE auto-searches and quickly connects while using the same or less battery.
Also, everyone, the 30mb/s won't stay for long... Once more towers are active and more lte phones are available, which is probably this summer, speeds will be down again.

*I have had T-Mobile for 6 years, just currently switched to a iPhone 4S with sprint in January...regretting it :|
Personally, I believe Sprint is going the wrong way with their plans for their mobile network. Now, before you discredit this post, hear me out...
Sprint is the #3 carrier in the US. There is absolutely no way they'll be able to trade blows with AT&T or Verizon as far as their mobile network or subscriber base. They will always be playing catch up to those two and even T-Mobile with their HSPA+ network. Now, here's where I believe Sprint should go:
Do the initial roll-out of LTE as they have announced. Immediately begin switching their network from EV-DO revision A to revision B and start focusing on their 3G network. I honestly believe that Sprint would be better served if they could provide a consistent high-speed 3G network; even more-so than they would be if they begin moving away from WiMAX and toward LTE. LTE should be in the cards, however I believe if they were able to upgrade their 3G network (which would be supported by ALL of their current phones) and start promoting the nation's only 3G network with 5Mb/s down and 2 Mb/s up and the strongest voice network in America, they'd be in better shape in a year than where they will be if they continue their current plans.
Just my 2 cents. Anybody have any thoughts?
OMG... That's even faster than my router.

Hmm so you have to search for it on Verizon LTE devices as well?!
It is most likely a placebo but I never use 4G because of the fact I feel as if it is like a wifi that can go away or weaken in reception depending on where I go...I like the GSM way of handling 3.5G/4G

No, LOL. It auto switches and connects like 1x and 3g do... That iPhone is probably the issue though.

Sprint is the #3 carrier in the US. There is absolutely no way they'll be able to trade blows with AT&T or Verizon as far as their mobile network or subscriber base. They will always be playing catch up to those two and even T-Mobile with their HSPA+ network. Now, here's where I believe Sprint should go:

5 mbps down on CDMA? Good luck. Sprint isn't just upgrading to LTE. They are doing a huge overhaul of their 3G network using lots of options including massively improved backhaul. From the speed tests I've seen in network vision areas so far, their 3G network should be on par with verizons network as far as speed goes. Coverage will be improved by about 20% as well. I agree they should upgrade to EVDO revision B, although I'm not sure what upgrades would be involved in that.
Back on the topic of the first post though, hot damn. I know speeds will drop once more people start using it, but those are impressive initial results.

From the little bit I've read about EV-DO revision B, it wouldn't involve any hardware upgrades. It would only involve a "firmware upgrade", if I remember it correctly. But yeah, 30+ Mb/s down is pretty sick. Even after "full-spectrum saturation", if we could get 10Mb/s in half of their 3G footprint, I'd be satisfied.

Great question... With 4G, it didn't even feel like a mobile data connection... Hopefully LTE auto-searches and quickly connects while using the same or less battery.
Also, everyone, the 30mb/s won't stay for long... Once more towers are active and more lte phones are available, which is probably this summer, speeds will be down again.

That is the reason that Sprint is only advertising speeds on LTE just below what Verizon is advertising. For the most part people in unsaturated markets will see speeds exceeding 20Mbps down on a good day. And those speeds may even hold up that high once Sprint starts releasing LTE on 800MHz next year as well. And according to some stuff that people have gotten access to, Sprint will be setting up phones to dynamically switch between LTE on 800, 1900, & 2500 so as to keep cell sites from being over-burdened. It will be a while before Sprint's LTE starts to suffer from over-crowding.

Sprint last fall flat out stated that they are not going to roll out EV-DO B. Network Vision will max out the capabilities of EV-DO A while they roll-out LTE on 1900 and 800. After that is complete and LTE Advanced is rolling out, they will be able to start taking existing 1900 EV-DO carriers and transition them to LTE as well. I expect that eventually, EV-DO will be phased out for a completely IP-based voice network using VoLTE. And Sprint is even releasing some devices with SVDO on EV-DO A so you can talk and surf at the same time until LTE is covering their entire network footprint.

Looking at the viper 4g lte options it seems there is no "on-off" setting for 4g lte. Looks like it will just be there. My area doesn't have lte yet so I can't be positive but I definately could not find a 4g setting of any kind
Sent from my PG86100 using XDA
I'll say it over and over again. Sprint doesn't have a 4G network. Also, Verizon has 50+M down and 12+M up
Then again, at this point in time who needs more than 3-4M down. just upgrade to rev-b and done.
This is a common thing for my WiMAX at the house but WiMAX is so freaking glitchy.
Sent from my PG86100 using XDA
This is typical WiMAX in my area.
1900mhz is going to be set up 5x5, but no confirmation if 800 and 2.5 will be set up on 5x5 though. More than likely they will be set up on 10x10 since there is a ****load more spectrum on there, especially 2.5GHz. There is 120mhz of spectrum in the 2.5GHz frequency that Clearwire owns.

and yet a year later i am gettn 38 mbs down
I've been with Sprint for 12 years and it has always been that you couldn't have data and voice at the same time with their system unless you were on the 4G connection. What changed with the EVO, I now have a data connection when I am talking. I can surf the net, emails come through, everything just like I have a 4G connection. I'm in Portland and we don't have LTE here so I know that's not it. I'm not complaining just curious.
It's called SVDO, simultaneous voice over data. Separate chips allow for this.
Well-known feature, but not well-publicized. The upgraded towers will allow SVDO on newer phones.

It has nothing to do with upgraded towers, its either a phone supports it or not. Hell, the iphone 5 doesn't support it and neither does the gnex, but the evo lte, gs3 and viper does.

It was my understanding it was a combination of both. I find it difficult to imagine that Sprint could've had SVDO for years if only phone manufacturers supported it.
Edit: there's really no clear answer, but you may be right.
Closing this as there is a lengthy thread on this already here...
SVDO....and yes its the phone that allows it. Nothing to do with a change they made nationwide to all towers overnight...

While this isn't a deal breaker as I get 4g about 90% of the time, it may be a bummer for other people. The galaxy s3 can do data and voice simultaneously while on 4g and 3g. I don't know why they did not include it on this phone. The gs4 only does simultaneous voice/data while on 4g. I download files all the time as well as ROMs and would hate for my download to be interrupted or broken if a call comes in. Just posting this to help anyone who has not yet purchased their s4 and has to have this feature... You have been warned!!

3g, being CDMA for Verizon, is not capable of supporting simultaneous voice and data. The Verizon Galaxy SIII was not able to do it on 3g either. Hopefully it won't be a problem too much longer as Verizon moves away from crappy CDMA and covers the whole country in tasty LTE.

The GS3 IS capable of doing voice & data simultaneously over 3g CDMA. I've done it many times. For the first few months of owning the GS3 my area was 3g only and I would talk and surf simultaneously all the time.I wasn't able to do it on any of my previous phones.
Thankfully I have LTE now but the GS3 can do CDMA+Data
I'm not familiar with the GS3, but I know the Thunderbolt was capable of simultaneous voice & data in either 3G & LTE, but that was because it had multiple onboard radios. The major downsides with having multiple radios is that it raises cost and constantly draws power (even when off due to leakage current). They probably made a design decision to not include additional hardware for simultaneous connections because LTE has become prevalent (as well as WiFi) so this isn't a major issue for most folks.
It was my understanding (since I've been with verizon, and 3 phones so far) that CDMA is 1X (equivalent of Edge on GSM) and EVDO is 3G while 4G is LTE (which uses a GSM style signal if I'm not mistaken also).
Granted the only phone I was forced to use 3G on was the Thunderbolt (no 4G LTE yet) so I guess I can't compare, but this is interesting if it actually is true. I'll have to try it later... tether in 3G mode and call someone

That is patently false. You may want to read the white papers on the last couple of generations of Snapdragons as well as the FCC filings for some phones. The simple fact is that the Verizon Galaxy SIII is capable of SVDO, along with a handful of other phones such as the Incredible 4G, Rezound, and Thunderbolt.

My HTC Rezound was able to do data and voice over 3g as well. I'm a little underwhelmed and overwhelmed at the same time with the S4. I like it, but there are some things I liked better with HTC.
SVDO on Verizon was never simultaneous over 3G itself, but data over 3G, and voice over 1X. eHRPD has nothing to do with SVDO as it's just the communication network used to hand off 1X to 4G. Apparently the Sprint GS4 can't do SVDO either, so it seems to either be a limitation of the new radio in the Snapdragon 600, or Samsung chose to not add in support this round.

You're a little confused on what eHRPD does, but in essence, the rest is correct.
Alright, so it is pretty much certain that 3G and voice are not simultaneous on the S4?

Since Verizon now covers 497 markets and 95% of their 3G footprint is also LTE, this warning will only affect 5% of Verizon customers. Glad i'm not one of them.
