[SPRINT] No data during a phonecall? - Nexus 5 Q&A, Help & Troubleshooting

I have full LTE service where I live, but noticed that I do not get LTE data when on a call. Is this because of the tri-band nature of the phone?

I believe CDMA phones that allow simultaneous voice/data require a separate on board chip, which the N5 does not have so it isn't possible.

It has to do with Sprint's software and not the chip: http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
This is the same info...except with the various cities where issues are occurring: http://www.geek.com/android/sprints...ed-service-for-the-forseeable-future-1577462/

Those links speak about no LTE at all, which isnt my issue. But, the general explanation of how the tech works makes sense.

Ah, that's true and a new wrinkle. In the past (before tri-band) Sprint LTE phones required a separate chip on board to handle this but it sounds like it's going to be supported via the tri-band set up instead in the future. I guess they're going to deploy "Voice over LTE" sometime but knowing Sprint we'll have moved on to the N5 2015 by the time that happens.

No sprint triband device (which is every device starting now) will ever have SVLTE or SVDO until the arrival of VoLTE in later 2014-2015. Developing and implementing SVLTE or SVDO on a device which utilizes both TDD-LTE and FDD-LTE technology cost far too much with far too little benefit for both Sprint and the OEMs.

no, but there are radio chipsets that can do both. I don't think the infuse has this chip. and the infuse is not spec'd to have lte capabilities.
2g,3g,and 4g are just marketing terms that are supposed to give a general idea to the consumer how fast it is.

Chatted with another AT&T tech support Jesus. According to him, "Infuse can run on both [HSPA and LTE] ... It is a phone designed for this transition since 4G level speeds are available with both LTE and the HSPA networks. And the Infuse can access them both. The Motorola Atrix as well ... I am not able to find documentation that is not proprietary. The information I have, since LTE is only in testing stages, is that LTE compatibility is not posted on the Specifications. The 4G speeds are currently being provided by an enhanced version of HSPA and HSPDA, and the phones are connectible. The 4G phones, such as designated the Atrix and the Infuse, will be able to access LTE once it becomes established via a software upgrade."

That's somewhat more believable - e.g. the hardware is capable but the radio baseband isn't yet.

the motorola xoom is lte upgradable so ther eis a posibility that the atrix is as well. this says nothing for the infuse. t-mo had the 4g flag on there hspa+ devices months ago and they cannot be upgraded to lte. it is a marketing game that started with sprint (wimax isnt all that fast compared to hspa which can run at 14.4mbps, hspa+ can run at 42mbps but att is only willing to supply 7.2 and 21mbps respectively http://www.intomobile.com/2010/06/04/data-speed-showdown-sprint-4g-vs-t-mobile-hspa/) 4g just means that it is faster than 3g was, infact wimax is barely comperable to 3g with hspa on many gsm networks. the 4g flag offers no garentee that it will support lte on any carrieer other than verizon. att reps often speculate and talk out of there assses, many times the information comes from customers and not corperate.
The infuse supports the highest speed of lte and hspa that ATT has out now and it will support the fastest they have by the end of 2011. My ATT Rep (for work) told me so and has one herself.
Edit: btw, my att Rep, represents my entire district, highly doubt she would talk out of her ass, but I do agree that the ones u find in the stores r mostly untrained

There' no way. If the Infuse were capable of LTE they would have advertised the hell out of that. Unfortunately reps aren't engineers and clearly don't understand the technology. Now the infuse may be capable of the fastest speeds, i.e. equal to whatever the LTE network is limited to, but it's not connecting using LTE.
i believe att will wait for the tmobile acquisition to finalize before releasing lte devices so they can use as many bands and cell towers as possible, easing network load issues and increasing coverage speed and reliablility.

Most of the population would raise a brow if u even mentioned the terms HSPA or LTE. They didn't advertise it because spending that much money to advertise a feature that only 5% (guesstimate) of the population knows about isn't the brightest idea.

Verizon built an entire ad campaign around LTE
http://androidcommunity.com/verizon...-its-the-most-advanced-4g-available-20101122/
And I can't seem to find the ad with the kid in the store, but they definitely push the fact that it's 4G LTE upgradeable. If ATT could, they would.

Agreed...
As you point out in your next post, carriers do not shy away from using technical terminology in their advertising. Further, even if this were the case, one would expect LTE connectivity to at least be listed on the spec sheet. Not only is it NOT there, but it was not on the sheet I saw back when this thing went to the FCC. I'm not a lawyer, but assuming what was posted was what the FCC was looking at, I believe AT&T would be in violation of the law if this thing supported LTE.
DING DING DING!
We have a winner!
HSPA+ and LTE are NOT the same thing and the radio bands have little to nothing to do with which tech is used. Remember when AT&T had their last Mea Culpa moment and enabled 3G on the 850 MHz band? (Because it penetrates buildings better)
If the Infuse *is* capable of LTE, that's news to everyone. It would be on Samsung's Spec sheet. The manufacturer would want to announce ANYTHING that it's capable of.

I'm from the SGS2 forum and we're having this debate too. A leak of the new 2.3.4 ROM that's supposed to be released at the end of the month has APN's for AT&T's LTE network along with PNGs of their unique LTE logos. So whatever version of the SGS2 AT&Ts releasing, it will run the same ROM as the international version. So, based on what you said about the "tech," what do you think what I just shared means? Is adding the 700mhz frequency to an existing radio all that's necessary to access LTE? Could the existing radios already support the frequency but have it disabled? No one really has a lot of info on LTE so it's kind of a mystery.
Here's an interesting article...
http://www.pcmag.com/article2/0,2817,2388526,00.asp

Does Mango support LTE?

I was under the impression that LTE would not be supported until Tango or Apollo, but the AT&T Titan II and Lumia 900 will have LTE while running Mango.
Is it something special about AT&T's LTE network that allows this? Or did Mango always support LTE?
If Mango supports LTE, how far off does an LTE WP7.5 device for Verizon seem? (Verizon said that the reason they don't support WP7 is due to lack of 4G LTE)
I'm not sure if 7720 supported LTE, but I think one of the newer releases does.
Mind you, LTE or not, AT&T uses GSM and Verizon uses CDMA, and it may just be that, while both are supported independently, the combination of CDMA with LTE is not yet tested. After all, most of the world uses GSM; CDMA wasn't supported at all until 7389 (NoDo).

Does it matter whether the phone uses GSM or CDMA for 2G/3G? LTE is a GSM technology (hence the LTE SIM cards on 4G Verizon phones), so I figured it'd be all the same to the phone.
I'd guess it's the combination of the technologies, since the phones aren't pure LTE. Being able to fall back from LTE to 3G CDMA, or being able to do data on LTE while taking a call on CDMA (something pure CDMA phones can't do at all), probably requires a bunch of extra work and testing.
It's also worth noting that Verizon may just be misleading people. They've shown no particular interest in the Windows Phone brand at all, right from the beginning. Between "Droid"-branded Android devices and iPhones, they don't seen too interested in other platforms.
I want to say yes it does because T-Mobile has 4G Windows phones at their stores.
T-Mobile isn't using LTE yet, though. Their "4G" is really more a "3.5G" technology - it's a faster variant of their 3G, not a completely new tech. It let them bring it to market early and deploy it widely, and it *is* pretty fast, but it's not LTE.

I stand corrected.
Mmkay. So my understanding is that Mango supports LTE on a GSM network (AT&T) as of now, but not LTE mixed with CDMA (Verizon)?

I guess I have to say on Verizon's defence, They only had a choice of 2 devices, because of their CDMA network. It's Microsoft that limited the options for Sprint and Verizon.
Yes, I do also believe that Verizon has Android and the iPhoney so far up their ass they don't see anything else...BUT, they have released in a Press statement that they would be interested in WP7 if it had LTE options available. Maybe the Lumina 900 would come to verizon...
Maybe we will, maybe we wont...
Waaaait... *Microsoft* limited the devices available to Sprint and Verizon?!? Not Sprint and Verizon themselves, who chose to use a technology almost nobody else in the world uses. Not the OEMs, who didn't build more CDMA-based WP7 devices. No, it was Microsoft, who will license WP7 to anybody who wants it and who have both a CDMA and a GSM version, who are to blame here? I'm confused.
The OEMs are the ones who decide what devices to manufacture. Of course, they do that based on having customers. If Sprint and/or Verizon were to ask for more WP7 devices, you can be sure HTC, LG, Samsung, Nokia, and maybe even Dell, Asus, or Sony Ericson would be willing to provide (Motorola seems to have no interest). Heck, Toshiba/Fujitsu *has* a CDMA/GSM hybrid phone running Mango - it was the first gen2 phone ever released! I'm actually surprised Sprint *hasn't* started importing it; the IS12T is a nice piece of hardware, and would complement the Arrive well.

It's not Sprint and Verizon's fault for choosing CDMA over GSM. They made the decision years ago, before smartphones even existed.
CDMA is actually the smart choice for a big country like the US. Each CDMA radio tower has a larger cover radius than GSM radio towers. Not only that, the call quality is usually better.
And China predominantly uses CDMA. As time passes, CDMA will become more prevalent.
That said, it's not Microsoft's fault, either. The reason there aren't many CDMA WP7 devices is due to OEMs not making many of them.

Keep in mind, the world is about 90-95% GSM. Microsoft decided to support the world wide standard before they went to CDMA on release(it was publicly stated by Microsoft). So, yes, it is sort of Microsoft's fault why there is only 2 US CDMA models.
OEMs knew this too. Make phones for 90-95% of the world or promote your efforts to a smaller market. It makes total business sense why it was done this way. Windows Phone 7 Didn't even support CDMA till NoDO months later after release.
China's CDMA is not the same as the US CDMA, its almost totaly different, WCDMA, they dont work together, so it's a different chipsets needed.
WIth that being said, Verizon or Sprint could of dumpped money at the project to get more WP7 devices but, with the problems with WM, they held back a little.
So, it's Microsoft and the carriers fault for the lack of CDMA phones. LTE is another thing totaly. We should hear about LTE WP7 phones at WMC coming up very soon.
A release for LTE based CDMA phones is another story....

OK, this is something I will address. There are three large mobile operators in China: China Mobile, China Unicom, and China Telecom.
China Mobile uses GSM/EDGE for 2G and TD-SCDMA for 3G.
China Unicom uses GSM/EDGE for 2G and UMTS for 3G
China Telecon uses CDMA2000 for 2G and EVDO for 3G.
What the local Chinese refer to as "CDMA" is actually W-CDMA which is a UMTS technology.

Whether or not Verizon choose to carry LTE Windows Phone is a political issue, not a technical one. Windows Phone does support both LTE and CDMA2000/EVDO.

Officially the N5 does not support Verizon explicitly, it may work but that is dependent on Verizon allowing you to activate the phone on their network. you can try but there are no guarantees. Personally i wouldn't hold my breath in anticipation.

CDMA bands, which is used for voice capabilites and 3G data: No. The Nexus 5 supports CDMA bands 0, 1, and 10. Verizon uses 2 and 5.
EDIT: It looks like my cross-referencing led me astray. Verizon and Sprint use the same 3G frequencies, Band 0 and 1, at 850 MHz and 1900 MHz, respectively. The Nexus 5 supports CDMA bands 0, 1, and 10. In theory, assuming you can get Verizon to sign off on it, it might actually be possible.
LTE bands, which is used for....LTE data: Yes, but it's very very limited. The Nexus 5 supports bands 1, 2, 4, 5, 17, 19, 25, 26 , and 41. Verizon mainly uses band 13, but is slowly rolling out band 4 support, but the odds are it won't be in your area right now, and the roll-out is slow.
EDIT: Again, more research suggests that through firmware editing, it might be possible to enable band 13 LTE on the Nexus 5. This is due to the Snapdragon 800 having band 13 support. It would be along the lines of enabling band 4 LTE support on the Nexus 4 (although we had official legacy radios that supported it, so we had something to go off of).
Besides: look at how Verizon is handling the activations of the Nexus 7 deb ("mobile version," if you will). They won't officially activate them, so you have to activate another device on their network and plug that SIM card into the N7, essentially working around them.
So, in short, no it's possible I would not buy this phone if you are locked to Verizon. My advice? Ditch Verizon ASAP. Not just for the phone, but because they are a shady company that blocks competition, among other things.

From the chart Both Sprint and VZW uses the same 3G FRQ only different Voice FRQ but each carrier can ride the Voice on the 3G bands so conceivably it can still work.

I thought that Verizon uses bands 0 and 1 for CDMA. Well I got the information from Wikipedia here: http://en.wikipedia.org/wiki/Verizon_Wireless#Radio_Frequency_Summary so I guess it could be wrong.
But Sprint devices can roam on Verizon's network, so that means that the Nexus 5 will be able to connect to a Verizon CDMA tower. The only problem is getting it to comemct to Verizon, and we still don't know what will happen when we pop an already active Verizon SIM card into the Nexus 5 yet.

Just because some sprint devices can roam on Verizon, doesn't mean ALL can. Every phone doesn't have the exact same frequency bands. That said, I would Imagine any newer cdma phone will be able to ride both verizon and sprint CDMA networks.
^^^ this. And for all we know band 13 LTE is supported by the hardware, just not by a Google that has a soured relationship with big red.

All LTE bands are supported by the baseband IP in the Snapdragon but it depends on the FW.
Activation of course is another story ie Nexus 7 LTE. Preactive SIMs should work but its up to VZW to accept it on their towers.
Well I can still hope. I'm on contact with Verizon until February and I'm about ready to kill my GNex. And I can't just go pay full price for a phone. Too much money, but the Nexus 5 is actually reasonable without contract. That's why I want it so bad.
And even when my contract is up, I can't switch, because everybody else is on my family plan. And I can't just go to T-Mobile $30 unlimited prepaid because there is no T-Mobile coverage at my house. (So frustrating, my housing development has towers for all the other three carriers, but when T-Mobile got their tower approved, the STUPID school people and parents got it blocked because it was within 1500 ft of the school. Like seriously I hate those people who appealed that, but that's another argument) And AT&T is too expensive for a single line. And Sprint just flat out sucks.
So I'll be on Verizon for a while, unless they can fight off those school people and get their tower built.

if you want other options, I've had lots of luck buying phones on Swappa.
If Verizon said yes, how would the non-LTE part of the phone know which network to hook up with? WithSprint and Verizon phones, they go automatically to their own network when activating. Would different CDMA networks pop up like with a GSM phone?

yea...sprint hasn't upgraded their network to enable simultaneous voice and LTE with spark....but i heard they are working on....i hope its not region based and they can get all the towers working on it at once
i miss being able to mess around on the internet while on hold

I have Spark (tri-band) network and Google Fiber in KC. Here are my speedtest results. The top 3 results are GS5 on Google Fiber WiFi, the bottom 3 results on Sprint Spark LTE.

Why spark being the fastest networks, can't talk and data same time.... Nonsense.

Im not in a spark area but still getting much better 4g speeds than my Note 2. Be it modem or whatever its nice

It has nothing to do with upgrading spark to enable voice and lte, sorry but that is completely wrong. Its device specific and not the network, the reason why its not possible is because there is only one radio path with the current crop of tri-band devices which makes it impossible to have lte and voice at the same time so nothing can be done on the network side to make it work. The reason why it was possible on previous non tri-band devices was because they had more than one radio path. I am sure its possible but maybe it just proved too costly and too inefficient to implement Also keep in mind that none of the other wireless carriers can do voice and lte at the same time. The gs5 on att/tmobile, once a call is initiated will drop lte all together but at least they still have the luxury of hspa to fall back on for data in the mean time.

Are you sure? Everything I gave read indicates it's a network issue rather than hardware
The s4 didn't have the svdo radio so we lost simultaneous voice and data on 3g and the original s4 could do it without the extra radio

Non-triband Sprint LTE phones "supported simultaneous voice and LTE (SVLTE). It could do so with two separate transmission paths from the antennas to the chipset. Voice/texting could run via 1xRTT on one transmission path. LTE could run a separate path, allowing data and voice to be used simultaneously."
"In contrast, Sprint Triband LTE devices do not support two separate transmission paths. They have one path, shared by voice/SMS and data. We were alerted to this months in advance. However, we did not realize that the network would have to run on Circuit Switched Fallback in order for this to work and what the ramifications of this would be."

It's a very informative and extensive read-up and explains, sadly, what is going on.

great article and it proves my point that simultaneous voice and data will be available via triband LTE in the future and its a network issue, not phone hardware
"Yes, this is an issue of all Triband devices, as they are dependent on CSFB to be present on the Sprint network in order to be able to use LTE.
The problem is not Triband LTE devices, but rather that the Sprint network is not currently upgraded enough in all places that currently have LTE"
Basically, Switchback Mode needs to be enabled for us to have simultaneous voice and data over LTE
" when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE"
Prior to triband phones, there were 2 radios...one for CDMA, and one for LTE...but now it's all over LTE radio for both calls and data...but not yet enabled, so it can only do 1 at a time currently

GS5 performs really well on tri-band. I'm getting up to around 40Mbps indoors at home, though I'm just a few blocks from a cellsite. The first 3 results are on Google Gigabit Fiber in KC, the second three are Sprint Spark.

Yes, I am very sure, its in the radio design. Even with previous devices that could do svdo and svlte, it was because of radio design of the hardware and not because of the network.

Read post #12. You are wrong, respectfully
yes, there is 1 radio..but spark will allow both voice and data over LTE once switchback mode is enabled, hence allowing 2 channels with 1 radio

Spark in NYC has been a disappointment for me. Haven't seen or noticed any improvements at all (I have an LG G2). Typically test as low as 2Mb to as high as 9Mb usually, which is just fine by me. Fast enough to stream stuff without buffering (most times) but it's just not consistent.
Frankly I'll trade some of that theoretical 40Mbps LTE speeds for better LTE coverage and 3G speeds and the ability to talk and surf over 3G and LTE any day. (I know it's not a big deal for lots of folks but i sure enjoyed it when I had the Galaxy S3 and Note 2).
Definitely jealous of your speeds though.

I am sorry but I don't think you understand what Robert was trying to say in that article. The reason why its not possible is because there is only one transmission path so its only possible for you to be connected either cdma or lte. The purpose of csfb is to let the tri-band device to know when to actually switch, thats why tri-band devices that are in areas that are not fully upgraded with csfb will have connection issues because it doesn't know when to switch. Simultaneous voice and data will not happen with the current hardware design of tri-band devices regardless of whats done in the network side.
EDIT: And when it talks about csfb is needed, its not needed to be able to do cdma and lte modes at the same time its needed to tell the device when to switch to either cdma or lte.

Come on guys, you don't understand what the article is saying:
"In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.
Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE."
When it talks about both cdma and lte modes, its not meaning both at the same time, it means being able to switch between the two seamlessly. Without csfb there will be issues switching back and forth for tri-band devices. In the last paragraph I quoted from s4gru, it tells you right there how it works. When you get a call csfb tells the device what to do so you can get the call, the transition is seamless except for the loss of data availability. Read the whole article not just that sentence.
EDIT: Here is a link to the thread over on s4gru that talks about it in more detail, ask your questions there to see what they say.

SPRINT simultaneous voice/data

Can anyone test if we have simultaneous voice and data on Sprint with pixel? I'm new to Sprint and horrified by the possibility of not having this. Also I only get 3g in my area, I'm not sure if I require lte to get this 'feature'
Sprint does not offer it on current handsets. Ironically, if you go back to 2013 it was a feature that was supported. Once sprint began building out their tri-band lte service, they needed to give it up due to technical limitations. It will not return until sprint activates voice over lte. I am not sure when that will happen.
