I haven't noticed until know that the SGN from Verizon shuts off 3g/lte while making calls.
Does this have something to do with ATTs contract with Google and Samsung.
I will leave this thread open as hope that we can resolve this issue. Please post your experiences. If your are not having issues with your SGN from Verizon please post. Thank you
Oh yeah wtf? Right?
Its a limitation of cdma.

OK but why did Verizon tell that me it does do calls and internet at the same time. Two customer reps told me this and one told me its in the manual. I'm going through the manual now
It's the network. Not some under the table contracted agreement.
It should be able to do voice and data anytime you have an LTE signal. On 3g you cannot though. Its a limitation of cdma.
Yeah Verizon has good towers here in California. Sh..ty service and BS like made me spill my coffee
Fine could we at least mod that out? I mean that's a load a crap
No.
Only LTE can coexist with calls.
Well what about a lte only switch if that was compiled than it would help right?

No. An LTE only switch would kill the cdma radio which is where the voice is routed on the Nexus.

*blink blink* TRWTF is the above question.
As stated, this is a limitation of CDMA, or at least Verizon's current implementation of CDMA. Every 3G phone exhibits this behavior, as well as LTE phones when out of range of an LTE signal.

There is one exception to the rule. VZW has updated their CDMA towers to allow SVDO which is voice and data over 3G, however the phone has to have a compatible chip set for it to work. The HTC thunderbolt is the only phone I know of that does SVDO when there is no LTE signal

Yeah, that's what's described at the "current implementation" link. As far as I was aware, SVDO hasn't been rolled out yet. Has Verizon already "flipped the switch" on SVDO?

SVDO was ready at launch of the TBolt. There was no press release when it launched tho. I don't think SVDO is going to catch on with VoLTE coming and the power hungry chips is just not q recipe for success

Welcome to CDMA. You can't do simultaneous talk and data over 3G. The only way you can do voice+data is if you're talking on 3G and doing data over LTE. If LTE drops while you're in a call, you have no data.

Well than i m guessing it would be a long shot to implement SVDO into a modded radios package
. Or maybe the hardware's incapable regardless

I just noticed yesterday that T-mobile has a 4G network in my area and I was wondering if there was a way to force roam 4G on tmobiles network? So that I could pick up 4G.
If its possible how?
Oh and sprint needs to hurry up and put 4g everywhere
You said it yourself. T-Mobile is HSPA+, Sprint 4G is WiMax. So, no.
Naa dude. HSPA+ is not compatible with cdma(sprint). Matter of fact t-mobile is using 4G now because its "trendy" and everybody else is using it. Their network is closer to 3G in infrastructure. But thats up for debate.
That sucks like hell. There's 4G here I just can't have it. AHHHHHHH!!!
Well if its like 3G I guess I'm not missing much.

You are on the money. HSPA+ is no more than an upgrade to existing 3G technology. If I remember right, it only has a theoretical max of 54 Mbps down. It is not, nor will it ever be, 4G.
Granted, the current 802.16e standard of WiMax is not 4G either...just waiting for that 802.16m standard to be finalized =). Which once that is complete, infrastructure can be updated and we should be able to utilize it with a simple firmware update.

No its way faster than your normal 3G. Faster than WIMAX too. Its nothing to pull down 7 or 8 Mb.

It uses the same radio for voice. The EVO has a separate 4G radio thats has to be activated and scan then connect. So 2 radios running at the same time would use more battery than 1 GSM radio running. Also CDMA has a tendency to use more battery when searching for signal in low signal areas.
Having installed T-mobiles 3g upgrade here in Chicago market back in 2008, I can say definitively that HSPA is just a radio cabinet addition to the existing cellular framework. Depending on the layout of the tower/site, "Flex radios" handle the data on 1, or sometimes more antennae, while the voice travels over GSM through remaining antennae. Very similar to ATT infrastructure, but tiny radios handling big bandwidth.
Having said all that, 4G is a silly buzzword that Sprint started, and T-mobile is now exploiting.
In a way, Sprint is just using extra radios on top of their existing 3G cellular, and just integrating the enhanced data speeds of Clearwire's network into their own.
T-mobile's speeds are indeed fast both HSPA and HSPA+, but to call them 4g may be overstating it, as it is just an upgrade to their existing technology, and not a new technology.
As another poster stated, nobody officially has 4g yet, not even Sprint, and until the 802.16 commission finalizes and LTE is launched we still won't.
To re-emphasize to the OP, not a chance, and don't believe the hype.
I can see sprint(or clear) and T-mobile going to bed for some real 4G'ness.

Yeah, I heard a rumor that Sprint may eventually adopt LTE.... It makes sense.
Wimax will make a great backhaul, and could stay in place, not to mention supporting cities and rural areas. But LTE will be the big daddy, and similar to WiMax, works on it's own and should be seamlessly integrated on top of cellular.
I'm not sure but I think it can work with CDMA or GSM, hooray for global WiFi!

I wouldn't count on LTE on Sprint just yet. Hesse denounced it last week; however, Sprint, Clearwire, Google, Time-Warner, and a couple others purchased Spectrum not only in the 2.5 GHz, but the 2.3 GHz band also. So the bandwidth is there and, in the past, Hesse has been quoted saying they can easily switch to LTE if need be.

Thanks for the info.
I think the most important thing in the article is that LTE can happen if necessary.
Sorry for getting off topic.
A few weeks ago, I posted a thread asking why does my friend get 4G, but I don't. If you are like me in a situation like this, the process is simple. In my area, there are 4G and Edge bands that phones connect to. My phone persistently connected to the edge band while my friend connects to the 4G. So lets get to the point shall we.
If you are having problems like me try this:
Go to your settings, wireless and network, mobile networks, and then select network mode. (After doing some research about GSM and WCDMA, I found out that GSM (3G aka edge) was slower than WCDMA (the newer technology 3G).
Select WCDMA. (For me it took a while so don't worry. If it does take too much time then select WCDMA + GSM.) You are going to have to select it anyway when you are done if you don't automatically connect to 4G.
When you select the combination, your phone should reconnect to your carrier provider and you should get 4G like me.
Oh. F.Y.I. T-Mobile doesn't actually have 4G. It's just a fast 3G network called HSPA, but they still display the 4G symbol when you have it. Hope it helps somebody.

Well sort of. Wiki mentions it but glazes over it a bit. It's a reference anyone can change of course so take it with a grain of salt. ITU relaxed their position about this time last year to include "evolving technologies" of which WiMax, LTE and HSPDA are all included.
So the reality is, all the carriers can make the 4G claim and sleep comfortably and the extended reality is, the speeds are all showing that next evolutionary step in speed, even if the technology as it sits today is just that. Steps toward LTE Advanced and whatever WiMax is calling their next version. As a TMobile customer, and one that it seems will stay with the TMobile branding it's unfortunate they are using a technology that has it's limits. But I'm getting 10-15Mbps on occasion and solid 7 to 8 Mbps speeds generally speaking so I'm not complaining. Until the carriers clear more spectrum what "G" it is isn't relevant to me. With 2Gbps, or even 5Gb soft caps I don't need to get to my ceiling any faster than I am now.

Well technically it is a quarter of the speed. If you are going by 100mbs defintion.
By industry standards , marketing, its 4g. But the term is meaningless. It is way faster than previous generation of phones.
So whatever, I'm calling 4g.
Multi-channel HSPA is capable of ~40Mbps, which is damned fast.
Call it what you want; technically LTE ir WiMax is 4g, but if it runs as fast as the others, who cares what it's called?
You would think at those speeds you'll burn through your data cap in days. I don't get the requirement for faster data speeds let alone just for minor things.

Can we end this stupid 4g/3g debate? I'll end it for you right now.
Until a few months ago NONE of the technologies out were 4g, not LTE, not WiMax, not HSAP+ ...BUT the ITU (International Telecommunications Union), which are the people that say what's what in the wireless industry, folded under the marketing schemes of the big 4 here in the U.S. and said that TECHNICALLY NOW LTE, WiMax, and HSPA+ All count as 4g. So...yes they have 4g. A few months ago they didn't. Now they do.
So what was the trick again? lol

Wikipedia is an administrator-approved peer-editing system. For one, there are references to back up the claims made, two, you can't just click "edit" then put in whatever you want. A Wiki admin approves all edits made, so bogus stuff can't just be easily added. (Sorry, I'm just sick an tired of people claiming wiki is a poor source for valid information, when in reality it's one of the most largest and beneficial information sources on the internet. Again, sorry, didn't mean that as an attack on you lol)
Either way, yes, our "4G" is fast, but in reality it's not in comparison to what it should be. And for those of you with worries about your data caps, these will be removed in due time. It becomes easier and easier to reach those caps without any effort at all (Google Music being a perfect example), carriers won't have a choice but to remove data caps, especially with carriers like sprint still offering unlimited data (for now lol)

KDDI uses CDMA 1X WIN and they have multiple phones that also feature WiMax.
The CDMA side of things may or may not work.. I've never had cdma 1x win h/w to see if its backwards compatible with what Sprint uses. KDDI's WiMax network runs on 2.6ghz.. same as Clearwire. So the device could at minimum run on our WiMax and Wifi networks for web browsing, sms over data w/ google voice and sip calling.

Actually, Sprint is the only one at the moment with LTE operating on that frequency.
I wouldn't be surprised if they, figuratively, hacked the LTE into the system for now and don't perform authentication.

The technology in LTE networks doesn't handle voice transmissions it only does data. So when you place a phone call on LTE it’s actually rolling back to the carrier’s older network to use CDMA tech to make the call.
I'm on Verizon and I can do both at the same time. I just tested it.

Well I believe you answered my question about this particular device but just to be clear both my Evo 4G and my evo 4G LTE would maintain data connection while I was talking on the phone not in an LTE area

So you are on Sprint? It all depends on the carrier too, I believe. If I remember right, AT&T used to be the only one that could do that that I knew of. I switched to Verizon and realized they didn't have that capability. Then LTE came out and gave that feature to them. I dont know about any other carriers though.
Again let me explain there has been many times I have been using my phone as a hotspot device to watch movies on my ps3 and I would receive a phone call in the middle of the movie I would accept the phone call and keep watching the movie without a problem. There is no LTE in my area of Western Kentucky I am on Sprint with an exceptionally fast 3G connection , I was surprised to find that this device does not have the same capabilities

If you used the Evo 4G it may have been connected to data via 4G, which is not the same as LTE. You can do the same with LTE being connected and voice calls. However it can't be done with 3g and voice as they use the same radio and like the above post says no US carriers have that technology. The only reason 4G and LTE works is becase they are data only on seperate radios. Of course it could have been magic.

Well I dont know then. All I know is that my Verizon Galaxy Nexus does both internet and calls at the same time with no issues.
I am posting this during an active call, with no 4g connection

I'm just wondering why any download I'm attempting to make will stop whenever I receive a phone call with my Galaxy Nexus?

Its not a difficult concept. Your data connection is being cut off because you're on a phone call. You might manage to post (something that can be done on even the slowest weakest connection) but something as intensive as downloading is always going to be interrupted.
063_XOBX is mostly correct.
the CDMA GN has a CDMA radio and a LTE radio. if you are not on LTE and you get a phone call, your data will shut off.
most HTC phones (esp the EVO) have a radio chip which allows data and voice at the same time as there are 2 CDMA radios in the phone.

Thank you for your reply, I really love XDA community I knew I could count on somebody for the answer

SVDO, while not officially supported, is alive and well. The Thunderbolt, Rezound, Incredible 4G, Viper, and Galaxy S3 on VZW are a handful of phones that are capable of simultaneous voice and 3G data.

The technology in LTE networks doesn't handle voice transmissions it only does data. So when you place a phone call on LTE it’s actually rolling back to the carrier’s older network to use CDMA tech to make the call.

No, VoLTE is not yet available, hopefully soon. That is not what I was saying. LTE handles data during a call, and CDMA handles the voice. If you are not on LTE or WiFi, there will be no data while on the call.

You are correct if only taking about CDMA. Cant say for any other carrier, but 100% with VZW you can do simultaneous data/voice if you are in LTE coverage.

To correct something I saw on this thread (and to complement previous commentaries):
- LTE is considered to be a 4G technology
In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users).[1]
Since the first-release versions of Mobile WiMAX and LTE support much less than 1 Gbit/s peak bit rate, they are not fully IMT-Advanced compliant, but are often branded 4G by service providers. On December 6, 2010, ITU-R recognized that these two technologies, as well as other beyond-3G technologies that do not fulfill the IMT-Advanced requirements, could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced compliant versions and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed".

- UMTS handles voice with a data call active at the same time.
