I dream of the day I can actully talk to somebody and look up something and send the message at the same time.....oh yeah...fix my compass too....lol Can anyine do that with software??

Oh good, finally. Looks like I'll start working on a Gingerbread build this weekend.

Nope. CDMA cannot run both data and voice at the same time. HSPA can, but CDMA cannot. This is a technology difference at the carrier level and software can't fix it.
(This is why the iPhone or Android on Verizon cannot do it either - but I believe LTE addresses this, so as carriers migrate that way...)

I've been waiting for a ROM for my Triumph ever since I first got it. Super excited about this find!

Verizon started introducing simultaneous data/voice on the Thunderbolt, even with 3G CDMA. It is possible, but the carrier (and phone chipset) has to support it. The technology is called SVDO. It enables EV-DO data while the phone is on a 1X call.
Found a write-up about it here.

Yes! I can't wait for a ROM too. I really hope the gps sync issue is fixed along with a new rom. It's not essential for me, but it would make this phone more likable than the Optimus V if someone will make a rom that fixes a lot of the issues this phone has.

Just to expound on this, the idea here is just a bit more complicated on simultaneous voice and data (you're exactly right and I dont mean to offend at all, I'm just adding to your point).
SVDO as you mentioned, and LTE, are two different things in the idea of simultaneous voice and data. SVDO, as you already said, allows a 1x and EVDO session to occur simultaneously, and requires the chipset to support it. The problem is that very very few actually do. The thunderbolt is one such phone, but it only does it in very specific circumstances and in a special way.
LTE is an IP-based technology, and therefore treats voice and data the same (like GSM).
That being said, VoLTE (Voice over LTE) is not an easy road because of the difference between 3G and 1x (circuit switched networks), vs. LTE networks (IP based). Because of these huge differences, bridging equipment must be used to work with the handoffs of calls between the networks. This process on phones is called eHPRD and is in place on all current Verizon 4G phones. This process will not actually be used though and is an empty feature. This process is so complex that Verizon has said that their VoLTE system will NOT be doing handoffs to 3G or 1x. Calls placed and received on 4G LTE networks must remain on the network. That is why for now, Verizon's LTE ONLY handles data, Verizon is not initiating VoLTE until the first half of next year.
Also keep in mind that while LTE + 1x voice is *technically* simultaneous voice and data, it is not SVDO in the sense of the acronym, which refers to sending voice and data over the same bands by using spare frequency from a 3G data session to "squeeze in" a 1x voice band in the space where previously, a entire 3G band would have been placed. LTE + 1x voice is really no different from using Wifi + 1x voice. Both rely on the idea of using 2 entirely separate bands for a voice and data session rather than squeezing a voice and data session into 1 band.
The thunderbolt can do SVDO because it has 2 radios (and a proper radio firmware to enable SVDO and allow the two radios to work as 1). The qualcomm processor + radio (MSM8655) gives the phone its 1Ghz processor and the capability of 3G and 1x (but only 1x is used on the Thunderbolt); and then a second qualcomm radio (MDM9600 Gobi Radio commonly used on 4G mobile broadband cards) capable of LTE and 3G. That's why it has antennas literally bursting at the seams (and into the battery cover), and why its battery life is amongst the worst of all the 4G phones. A call received on the Thunderbolt always goes to the 1x radio on the MSM8655 processor. 3G and 1x treat data and voice separately, with 1x capable of voice or data and 3G capable of simultaneous voice and data only if SVDO is supported on the chipset (the thunderbolt nor any other 4G verizon phone support SVDO on a single chipset, the thunderbolt is able to do it with multiple chipsets). I'd make a table, but I'm not really sure how to, so in case my rambling on was a bit confusing, I'm going to lay out a concise list assuming Wifi isn't being used (which as said above is similar to LTE + Voice on current networks) That will change next year.
Verizon Thunderbolt:
When in a 4G LTE zone:
Data is sent over the 4G LTE radio from the MDM9600, while received or placed calls to the phone go over the built-in 1x radio in the MSM8655.​
When only 3G is available:
SVDO is activated through software. Data is sent over the 3G radio from the MDM9600, while received or placed calls to the phone go over the built-in 1x radio in the MSM8655. The 1x band for the call is squeezed into the same band as the 3G data session using SVDO.​
When only 1x is available:
Only the MSM8655 processor has a 1x band, so the session can be either data or voice, but not both. Even if the MDM9600 had 1x, it would not be possible to have simultaneous 1x voice and data because it is impossible to squeeze a 1x band into another 1x band.​
Droid Charge, LG Revolution, and other current Verizon 4G phones: The phones all share the fact that their 4G radio only supports 4G, there is no 3G or 1x data band in the second radio like the MDM9600 used in the Thunderbolt.
In the case of the LG Revolution, the same MSM8655 used in the Thunderbolt gives the phone its processor, and in this case, its 3G and 1x bands (The 3G is enabled on the MSM8655 on the Revolution but not on the Thunderbolt). This is because its second radio, the LG L2000, is only capable of 4G LTE.
In the case of the Droid Charge, the Hummingbird processor used does not have a built in radio. While the Thunderbolt and LG Revolution use a (Processor + Radio) + Radio methodology, the Samsung Droid Charge uses a Processor + Radio + Radio method. The Droid Charge has a VIA CBP7.1 radio to handle 3G and 1x, as well as Samsung's own CMC220 radio that once again, is only capable of 4G.
This results in the Revolution and the Charge behaving the exact same way:
When in a 4G LTE zone:
The phone's 4G radio handles data, while the phones primary radio handles voice.​
When only 3G is available:
On both phones, the 3G / 1x radios do not support SVDO. Therefore, the phone can support a single 3G data session until a call is placed, in which case the phone drops to 1x voice, removing data access while in the call.​
When only 1x is available:
Same as when only 3G is available, except the phone is holding a 1x data session until a call is placed, in which case it becomes a 1x voice session, removing data access while in the call.​
As for current 3G phones, no singular chipset fully supports SVDO, and since almost all phones only have one 3G/1x radio, simultaneous voice and data on these phones is impossible.
SVDO requires the carrier to support the technology, as well as the chipset in the phone to support it and the software to enable it. So far, no individual chipset supports SVDO. This includes the MSM8655, otherwise the LG Revolution would support SVDO over the 3G/1x bands built into the processor. But it does not. This first gen hardware is hacked together as 3G phones with additional 4G radios. This allows the Thunderbolt to get SVDO simply because its 4G radio also supports 3G. Since the software is written to allow SVDO, the two radios work together to provide it.
Late next year I would expect to start seeing matured single-chip solutions containing 4G + 3G / 1x in a single chip. These chips should allow built-in SVDO + VoLTE. Until then, there's not much support for it in current hardware without a multi-chip solution.
Lastly, I'm sorry for the long, drawn out, entirely off-topic post. But I hope it clears up some thoughts as to where we are headed with current CDMA technology and the transition to LTE.

Does the incredible 2 have the right hardware to support svdo?

[Q] Data drops from LTE to 3G/HSPA During phone call

When I make a phone call my data connection switches from LTE to 3g/hspa. Is anybody else seeing this?

Same here on AT&T Downtown Los Angeles, drops to HSPA+. Honestly to me, it doesn't really matter.

thats what its supposed to do.
when on a call, it goes into HSPA/3G, then after the call ends, LTE should kick back in.
thats how AT&T LTE works. there is no VOICE over LTE yet

LTE is a Data only network, No voice calls should go through it.
The LTE standard only supports packet switching with its all-IP network. Voice calls in GSM, UMTS and CDMA2000 are circuit switched, so with the adoption of LTE, carriers will have to re-engineer their voice call network. Three different approaches sprang up. Most major backers of LTE preferred and promoted VoLTE (Voice over LTE, an implementation of IP Multimedia Subsystem or IMS) from the beginning. The lack of software support in initial LTE devices as well as core network devices however led to a number of carriers promoting VoLGA (Voice over LTE Generic Access) as an interim solution.[13] The idea was to use the same principles as GAN (Generic Access Network, also known as UMA or Unlicensed Mobile Access), which defines the protocols through which a mobile handset can perform voice calls over a customer's private Internet connection, usually over wireless LAN. VoLGA however never gained much support, because VoLTE (IMS) promises much more flexible services, albeit at the cost of having to upgrade the entire voice call infrastructure. While the industry has seemingly standardized on VoLTE for the future, the demand for voice calls today has led LTE carriers to introduce CSFB (Circuit Switched Fallback) as a stopgap measure. When placing or receiving a voice call, LTE handsets will fall back to old 2G or 3G networks for the duration of the call.

[Q] Nexus 5 LTE & HSPA

Hello everyone,
Just got my Nexus 5 with carrier AT&T and got my LTE activated using the IMEI that came with the N5 and everything works great. Just a quick question regarding the icons that are shown depending on which network you are on. When on LTE it will show LTE above the signal bar. When not on an LTE band it will switch over to H. My understanding is that the H stands for HSPA+. Would this be the equivalent of 4G? I was under the assumption that the H was basically 3G. I also thought then when using LTE it is considered LTE/4G, so wouldn't the LTE switch to a 4G symbol, or does the Nexus 5 not have this and that would be what the H is referencing.
Thank you.

H is hspa+ which is faster than 3g but not as fast as lte. I am usually on H+ or lte. I rarely get the 3g symbol on AT&T. I also found that H+ is almost as fast as Verizon LTE. I think it is due to do many devices on their network.

Thanks, so basically you won't get the 4G symbol on the Nexus 5 using AT&T? Mainly what happens is i'm on LTE, then when I make a phone call it switches to H (HSPA+). I thought AT&T is able to do voice calls over a 4G network. I may be wrong.

You may have to manually add in AT&T's LTE apn (which you can find with a quick google search) if your phone doesn't automatically pick it up. Also make sure your SIM card has been provisioned to work with the LTE bands (use with another 4G phone ex. S3, HTC One)

Well I get LTE, I just don't get 4G. I figured the phone doesn't show a 4G icon, but if it does, then I'll check my sim in another device.

Google just changed the "4G" icon to "LTE". On jelly bean, LTE would show "4G" if you had the hybrid N4 radio flashed. hspa+ has always shown "H" on the stock ROM. Some custom ROMs have you the "H+" symbol though.
As for voice calls on at&t, they go over their hspa+ network, at&t uses their LTE for data only at this time. BTW, at&t considers their hspa+ to be "4G".

4G and LTE are the same thing. LTE is a denotation of the network standard just like 3G is EDGE. If you're getting LTE above the signal indicator you are on the 4G network.

Yeah, it is the same on T-Mobile. When they refer to 4G, they are referring to HSPA+ (or H). I like to call AT&T and T-Mobile's 4G, fauxG since it is really just an improvement upon 3G. I don't know who shot first, but I wish the marketing teams would have called it 3G+ or something instead of lying to everyone or at least referred to LTE as 5G. So now everyone has 4G and 4G LTE and really LTE deserves more as it isn't a hack job to get more speed. It will replace all the legacy networks and even eventually be used for voice transmission.

Yes it switches because they're currently you cannot surf the web while being on a phone call with LTE, so it auto switches to hspa+ so you can surf the web while talking

It's no big deal. I considered HSPA+ more or less 3G+ anyway. All is well, you guys are great help. Got my phone unlocked the bootloader and set everything up, got my LTE (which I did not get with the nexus 4). Time to play around with the phone some more now.

I have had my Nexus 5 for a few days now and I have noticed quite a difference in reception between lte and hspa on T-Mobile. I will have lte marked and have one maybe two bars. Then I switched to hspa and then my bars went all the way up. Why is this?

4G is a communications standard, that currently no one meets. In fact, many people report that T-Mobile HSPA+ is faster than Verizon LTE in their areas.

I'm with Australian network provider Telstra, and my phone shows 4G all the time(regardless whether it is transmitting data or not) when I'm in 4G coverage, 3G when I'm not in coverage and not having data acativity and H when it is transmitting data. Do you think it is the different device model and/or the network provider contributed to the difference between mine and what you guys have in the State?

This confuses me. Can't the nexus 5 use both at the same time? You're getting text messages over HSPA(+) with LTE on.
I'm still puzzled why when I make a call why LTE goes away and HSPA+ shows up. This is on T-Mobile.

Well, I have some good news to report. I was having the same issue as you and really getting down about it. I went to my nearest T-Mobile store and told them of my situation. The rep called tech support and he did some sort of reset to my account, I am not sure what exactly. I also asked if I could get a new SIM. I was given that new ISIS SIM and as soon as my phone fired up, it started using LTE. After I left the store, from being in my pocket, it was on HSPA for a few moments and then it finally chose LTE and stuck with LTE the entire time I was within its coverage. I am really happy with my phone now, it now behaves like my hacked Nexus 4 on LTE did.

This isn't *entirely* true.
You'll see the LTE symbol when you're on LTE, that's easy.
You'll see the H when you're on HSPA or HSPA+, which means you'll see it when you're on the network that old phones used to just call 3G.
The other symbols are specifically for Edge. I know it doesn't seem like it, since one is a 3G symbol, but do a speedtest and you'll see it. Modern phones display things poorly for connections because of the differentiation of HSPA and HSPA+. It's obnoxious.

LTE, and even HSPA+, are considered 4G.
As for the 'Why does it switch from LTE to HSPA+ when I make a call?' question, LTE does not support standard switch-based telephony, meaning you cannot make voice calls using the network. Some carriers (I think Verizon is ahead, but I don't remember) are going to be supporting VoIP soon (voice over IP), which allows calls to be made using the LTE network, but they're all data-based (think Skype). As such, current phones will switch to HSPA+ or CDMA to make the phone call and then switch back once it's done.

That's not really accurate. Verizon's newer phones (Galaxy S3 for example) will let you call while on LTE. That's why I'm having such a hard time understanding why the N5 won't let LTE stay on while making a call. Doesn't it have a radio for data (LTE) and and radio for voice? Seems like both should be working in parallel like on VZ.

[SPRINT] No data during a phonecall?

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/

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.

How do you force LTE mode and not HSPA?

on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster

Dial *#*#4636#*#* on the keypad and under phone settings there is LTE only. Your phone won't work for calls possibly after you do this and you won't get data outside of an lte area.

man, i grepped a whole thread in relation to this very issue, it's a very imformitave read on LTE network overlays on legacy & upgrading cellular & the intro to these single chip, single pathed qualcomm snapdrgon families, but it got closed;
the nexus 5 only has one chip to handle all networking, from wifi, voice calls, to bluetooth;
it's doing quadruple duty, a question, what technology are you using, gsm, or cdma?
~edit~
nevermind it, you mentioned hspa, so it is gsm..
i'm reading up on lte to gsm handover right now.. lol

that's what i'd like to know.. lol
necro'd as in meaning; left'd to wither inthe wind, or because it's 5 months old, it's not worth posting to anymore..
that's why i asked if the issue was solved, there's threads, & posted STILL asking about LTE faulty connections scattered all over the place, so i guess the issue isn't solved in relation to this handset..
i'm in the school of thought, that like a car, or any tool one would use, it's best to grasp a critical understanding of what it's being used ON..
(am i wrong in this assessment?)
from there, once you understand the build of your tool, you compare it what it's being used on, with it's pros & cons; heighten it's pros, lessen it's cons..
wen i went to mexico just two weeks ago, i ordered two telcel prepaid sim cards to use for that 5 day stretch, i noticed i only got version 5 sim cards that didn't do lte that telcel provided, i called back & asked why, & was told that yes, telcel DID provide lte, but not in the area i was visiting, the highest i would get was hspa+, & only in mexico city & within cancun proper would lte be utilied..
knowing this, & knowing i would be off the beaten path on the beach & not in the major city, i opted for the cards sent, settling for the highest hpsa+ speeds..
maybe not all of us, but many of us, purchase our vehicles (& phones) based on critical knowledge of the phone & network in unison, **if we want more utilization from our hansets**
remember that scene - http://nilvideos.blogspot.com/2008/09/transporter-bank-robbery_17.html

I don't want to try disabling the hspa and calling without knowing I can flip it back on easily..

hey, are you on tmobile?
if so, tmobile's roaming is set within it's sim, *unless you manually select a particular nework*
"The device detects and registers on wireless networks inside T-Mobile’s calling area, but roaming networks are usually restricted to T-Mobile SIM cards. You can manually select a network only in areas where T-Mobile does not own GSM spectrum." - ~attachment~
our nexus 5s use single chip, single pathed radios, only one path is used at one time, right?
on the network side, things can be set up pretty differently -
3.3 SUBSCRIBER DATA ASPECTS: USIM/ISIM
Coexistence of LTE with WCDMA/HSPA and GSM Network requires a smooth transition of home location
register HLR towards HSS based on 3GPP specifications. This also helps in providing next generation
Data Layered Architecture that addresses operator’s needs regarding centralization of subscriber data
used for authentication across multiple layers of the same session.
The SIM/USIM is the security token in 2G/3G networks for authenticating a subscriber in the operator’s
HLR. The USIM will continue to provide user authentication function at the access level to the LTE
network.
However, it is necessary to define a mechanism for service level authentication as well, for services such
as the IMS. The ISIM (an application on the UICC) is defined to hold both the user’s access level
credentials and the IMS Private User Identity that is stored in the HSS. The ISIM enables the user to
authenticate to the LTE operator’s IMS network and access its services.
3.4 ROAMING SCENARIOS
There are two roaming scenarios based on home tunneling compared to home tunneling with the
possibility of local breakout as shown in Figure 9. The 2G/3G networks refer to legacy CS or PC based
accesses like GSM/WCDMA in the network

to set up domestic roaming on this type of handset ACTUALLY make you roam moreso on other US networks, even though the sim card is provisioned with what network is OK'd?
we're not talking from an older, dual pathed chip paradigm, when that meant exactly *that*..
these newer phones are different beasts..

Yes I'm on T-Mobile.

LTE has an all IP backbone, with no circuit switching mechanism, the network would provide that, & from my understanding from reading up on it, wcdma provides the **IP flattening** for voice on the gsm networks, just as ehrpd does for cdma networks..
what would happen if you switch on domestic roaming in -
APN & data settings
To set the Access Point Name (APN) and turn on data settings, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Check the Data enabled check box.
6.Check the Data roaming check box to receive data when roaming domestically
7.Uncheck the Data roaming check box when roaming internationally to avoid incurring roaming charges.
8.Tap Access Point Names
9.Choose from the following:•MetroPCS - fast.metropcs.com
•T-Mobile GPRS
•T-Mobile GPRS - fast.t-mobile.com
do you think you'd simply, roam on another provider?
i suspect it would aid your phone in it's LTE to GSM voice handling..
i suspect strongly.. setting it to *LTE* in -
Switch 2G / 4G / LTE
To change the band between 2G, 4G, and LTE, follow these steps:
1.From any Home screen, tap the All appsAll Apps.pngicon.
2.Tap Settings.
3.Under 'WIRELESS & NETWORKS," tap More... to display more options.
4.Tap Mobile networks.
5.Tap Preferred Network Selection.
6.Choose from the following:•LTE
•3G
•2G
..........................
on yet another note,, your handset may be functioning more properly than you could imagine; in your OP
"on the device the preferred network type is LTE but most of the time it falls back to HSPA mode and not LTE how do you force the LTE mode only? My location get's 3-4 bars for LTE coverage and all 5 bars for HSPA but LTE is faster"
tmobile's LTE may simply be having issues for a spell, to be worked out at a later date, & you're falling back on hspa+ asa failsafe..
you may not have to change a darn thing..

In the Palo Alto area LTE doesn't always stay on and the HSPA+ does not actually transfer any data. Sometimes hspa+ is on when weak LTE is available. In situations where I want wreak LTE over strong but useless hspa+ I need to force LTE not just prefer it
