VZW to ditch CDMA.

Do you ever see a day when VZW will ditch CDMA and start using GSM? I hate not being able to use my phone with another carrier. I also don't see any real advantages to CDMA. Any thoughts or opinions on if you see this happening?

Verizon will switch from CDMA to GSM, probably never. CDMA is very well suited for covering long distances with a minimal number of towers. Therefore, CDMA is the best platform for countries with large land masses. CDMA is more secure, and the phones are more energy efficient. Also, CDMA phones produce far less EMI.
If you really need the international roaming, there are Verizon phones with global capabilities. Or switch to T-Mobile or AT&T, and deal with that headache.

I would love to see verizon ditch CDMA for GSM! Its a pain to have accumulated phones that I will not be able to use once I switch to a GSM provider. The problem is that it doesn't seem like there is any incentive for Verizon to WANT to switch from CDMA

CDMA is better than gsm in some ways and gsm is better than CDMA in some ways I prefer cdma

Verizon already has been rolling out LTE, is it not just a matter of time before they start to put all services onto that? I would think that at some point Verizon just won't need CDMA anymore.

There lte is CDMA...

Nope its CDMA at a higher frequency to allow faster speeds. How do you think these little companies do it like cspire? They can do it for cheap on CDMA

LTE is based on GSM technology. On current Verizon LTE phones, CDMA is used for voice and texting (and data when there's no LTE), but data (when there is LTE) goes over LTE. That's why you guys have SIM cards in your CDMA devices.
What verizon is planning to do is abandon CDMA for completely LTE phones in the future. What this means is voice, texting, and data will go over LTE, similar to VoIP. It's called VoLTE, which means Voice over LTE.

It's actually at a lower frequency than their CDMA bands. 700mhz band. Lower frequency has better wall penetration. Frequency has nothing to do with bandwidth either.

I know for a fact that lte runs on CDMA at cspire it may be different but there isn't no sim on cspire phones and they couldn't afford to upgrade all there towers with gsm anyway so is there different kinds of lte?

GSM doesn't just mean SIM card. LTE uses GSM protocols. Sprint is the same as CSpire; no SIM card slot. However there's a chip that emulates a SIM card inside the phone. It's probably the same case for CSpire users. The HTC One on Sprint has a SIM card slot though. So does the iPhone 5.

Well, if a phone supports LTE, it doesn't necessarily mean it can do GSM. For example, the HTC Rezound and most newer phones on Verizon do GSM, but only because the phone happens to support it because the chipset is designed for global roaming. But the Galaxy Nexus on Verizon, for example, doesn't do GSM even though it can do LTE.
There was a guy who took the Photon Q on Sprint (the Motorola slider), unsoldered the chip that pretends to be a SIM card, and soldered on a SIM card reader. He was able to use normal SIM cards in his Photon Q afterwards.

don't some CMDA phones have sims though?

Those are phones that also had a separate GSM radio in them for traveling abroad (like the DROID 2 or even the Touch Pro 2, which were not LTE phones).

Ahh, ok. nice to know. Going to attempt to get my D3 on USA ATT this weekend. I hope it works as I really don't want to shell out money for a new phone. I like my D3

There going to leave CDMA eventually but not for GSM. There is a new form of LTE they will eventually adopt because its backwards compatable with the original LTE . Than they can pull all of there cdma and older lte equipment along with the 1x stuff that has been phased out and removed as it dies.
I dont see all of this happening for another 4-5years for the full switchover though and its posable they may leave cdma in some markets to help coverage as it seems some areas LTE just eats it.

[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?

You realize LTE is also not REALLY 4G...
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. Of course, now AT&T and T-Mobile both offer LTE and HSPA+. Which puts them above Verizon in my eyes, because when LTE goes out, you have HSPA to fall back on.

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.

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".

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.

[Q] No LTE icon? (my N5 only shows H)

Hello,
I have been using the Simple Mobile $70 plan for unlimited 4G data. Since I got my brand new Nexus 5, I was wondering why I am not getting "LTE" icon on the notification bar. It only shows H/3G which means (I think) HSPDA+. This is weird since the APN is set to T-mobile LTE (fast.t-mobile.com). Can I fix this if I change the service provider to, for example, T-mobile (assuming Simple Mobile 4G is not LTE)? I heard some people are getting LTE icon with Straight Talk and some don't.
Thanks for your advice in advance!

it depends on if u have LTE service in the area you are at. For instance, I only get 3g service at my house , but if i go a block west of my house i get LTE service. Also i have noted that the nexus 5 have weak reception, some spots i can browse and make calls with my Iphone but at the same spot nexus 5 has no service.
And dont trust the T-mobile coverage map, its a bunch of BS. There are so many areas that I know of that have no service at all of any kind and are shown as great service areas on the map. Best way to find out coverage is to just go to different places ( indoors and outdoors ) and test it out.

You are right. The problem is it doesn't work in my house as well as on campus and in any Chicago downtown area. Maybe I need to try another provider? But buying a new sim card, porting, and changing provider are time- and money-wasting.

You should try using an att sim and see what kind of coverage you get. Att is definitely more expensive than t-mobile and you dont get unlimited data no matter what but i see no point of having and paying for a service which you can not use. Also you can ask someone else who has the nexus 5 and t-mobile how the coverage is for them in and around the areas you frequent, it might be a device issue.

Nope. Simple Mobile is an MVNO that operates on T-Mobile's network. The nexus 5 supports all the bands that T-Mobile broadcasts on.
Does Simple Mobile even offer LTE? Because according their website they do not, but they offer hspa+. Which is kind of considered 4g speeds. No mention of LTE.

I dont see the connection between the processor and bandwidth. I have no idea what bands simple mobile uses but thats based on the radio of the device. As far as i know Nexus 5 supports 3g/4g(h)/LTE for tmobile and att, never used sprint so cant say.
Yes i got my phone from T-mobile and i just put my work att sim card into it, all that was needed was a reboot and it automatically picked up att service with LTE. Data speeds are great, getting 8+ Mbps with only 2 bars of service.
I do think that the nexus 5 have reception issues, the same att sim card in an htc one or iphone 5 gives minimum 4 bars but data speeds are around the same (+ 2~3 Mbps) but more consistent. With t-mobile, i was missing calls, receiving texts hours later and the phone was just hopping between LTE, H and No service.

Yes, I remember OOKLA test once peaked 14Mbps, so it's not just 3G. After some research, I found that Nexus 5 works with LTE bands 1/2/4/5/17/19/25/26/41 while T-mobile uses 4 only, Verizon uses 4/12, AT&T uses 2/4/17/29/30, and Sprint uses 25/26/41. Is it a good idea to change the provider to AT&T, or Sprint? Do they support porting in most cases? Thanks.

Actually there is a direct connection between the CPU and the bandwidth support because the radio is part of the snap dragon 800 'system on a chip' CPU.

After some research, I found that Nexus 5 works with LTE bands 1/2/4/5/17/19/25/26/41 while T-mobile uses 4 only, Verizon uses 4/12, AT&T uses 2/4/17/29/30, and Sprint uses 25/26/41. Is it a good idea to change the provider to AT&T, or Sprint? Do they support porting in most cases? Thanks.

I would suggest straight talk if you want LTE that. $45 a month. Order their At&t based Sim.

Actually there is a direct connection between the CPU and the bandwidth support because the radio is part of the snap dragon 800 'system on a chip' CPU.

I never really looked into the SOC on the snap dragon, the radio modem being on the die with the CPU would definitely effect the throughput. Thanks for the link, I have some further researching to do

You mean the one they call AT&T Compatible Micro SIM Card, right?

Lollipop enables band 4 XLTE

Not sure if this information has been posted...
http://www.phonenews.com/verizon-ht...te-enables-band-4-xlte-coverage-access-30047/
Verizon has begun rolling out the long awaited HTC One M8 Android Lollipop update to owners of the smartphone this week and in the process, enabled expanded access to its LTE network by activating the previously dormant Band 4 (1700 AWS-F band) for access to its XLTE high-speed network overlay. This update is expected to substantially improve coverage for customers that have been dealing with network congestion on the primary 700Mhz LTE network. The carrier is rolling out the update in waves and has posted a*detailed changelog*with the changes on its support page for the phone.

Its dated for about a week ago so I'm gonna say its the update we just got. I don't know what app we could use to see what bands are active or enabled. I'm sure there is something out there though.

Maybe it was Viper ROM but I am pretty sure mine has been active as of kit kat....as I can get speeds of 70-80 down in areas that only used to be 5-10

I wish i can get speeds like that

Hm, I had band 4 when I was running Viper and some other ROMs as I recall. I wonder if it enables Carrier Aggregation with band 4, which I asked last night in Q&A section.

Well depends on where you live....nowhereville Montana isn't getting xlte deployed as quick as metro NJ..but even then I'll get crazy fast speeds at work but if I walk a block away I get only .3 on LTE! So even in highly congested areas they haven't upgraded to xlte.

Use LTE Discovery app if you want to know what band and cell you're on. It's very useful.

"Lte discovery"app says I'm on lte band 13, guess my areas not band4 yet.

Same here in Tennessee

LTE Discovery is a real winner of an app. It's what I use as well.
Band 4 XLTE in central Virginia working like a charm.

Correction the cell tower on the other side of town is xlte band4 30Mbps up/10Mbps down

I thought the same thing...but if you follow the moving arrow (ex. turn your phone around in circles like a weirdo...you may eventually change to XLTE band 4 (happened to me after about 60 secs). Until this cool app I just tried bc of this thread...I didn't even realize XLTE was rolled out around here yet.
The XLTE tower must be far away though, bc I only get 1 bar of XLTE and my speed tests suck when locked on.
Speed Test XLTE: 18.69 D | 1.05 U
Speed Test LTE: 22.64 D | 11.68 U
Speed Test WiFi: 127.31 D | 44.21 U (screamer!)

Exynos in the US?

Has anyone gotten an Exynos S7 to work in the US with any of our carriers?
I'm so desperate for a rooted S7 Edge that I'm ready to change carriers if I have to. :crying:

It probably will work but it won't work well, especially with T-Mobile (no band 12 or VoLTE). Just wait m8

I have been using g930s variant along with g930f kernel + roms in the us tmobile. I live in DC and LTE has been just fine. Maybe i am missing a band but whatever

I'm using the Exynos S7 on cricket and it works flawlessly. Performance is stellar, battery life is incredible and I get great LTE coverage everywhere.

How can you confirm that? I got the Exynos international version, with T-Mobile SIM card. I have AIDA64 but not sure where to look to confirm or deny that the LTE Band 12 is not there.
Cheers,

T-Mobile has to certify and allow the phone to work on band 12 or else it won't be able to make 911 calls. They've verified the US S7 but I don't think they verified the international version.

Hello there,
Well, I can confirm that LTE Discovery App shows the LTE Band 12 working with T-Mobile. I have walked around the building where I work, and it switches back and forth from Band 4 to Band 12.
Hope this helps someone asking if the Samsung Galaxy Exynos International Version SM-G930F works with T-Mobile LTE Band 12 !
Cheers,
G.

it's frustrating that others have said recently that band 12 is NOT supported. what about wifi calling?

Hi there !
I belive that WIFI calling and the reduced Internet speed while on a phone call, are the two things that are different on the Exynos. Tell me how to check and make sure WiFi doea not work and I will try for you. I have tested the second one, and indeed the Internet speed is way reduced when talking on phone. Depending where you are, it is either H+ or 3G.
Hope that helps !

i believe there should be a setting for wifi calling within the "more connection settings". if it's not showing within the settings, then it's not supported.
as for band 12, how reliable is that app you used? a lot of people have mentioned that band 12 is not supported on the exynos model, so i'm really curious how yours has it.
thanks!

OK, there is no WiFi calling setting under there.
As for how reliable the App is, I have no idea, sorry. I searched and found it was mentioned in XDA for checking this kind of settings/capabilities. I will take a screen capture of it once I am in a building and it is showing the band used. My understanding is that LTE Band 12 is particularly good and improves signal inside buildings.

ok thanks for checking! yea band 12 is important for me, as i'm in NYC and inside buildings all the time. the extended range would definitely help.

That's because the Exynos version doesn't support VoLTE. Idk about WiFi calling though

Well i have Canadian Exynos Verison of S7, while roaming in US i had full LTE coverage of both AT&T and T-Mobile and with really good speeds
Sent from my SM-G930W8 using Tapatalk

The Internattional version does support band 12. and it works, however for VoLTE you have to find a firmware that has it which is hard. the Czech t-mobile firmware has VoLTE but no WiFi calling

The "F" international version also has Band 17 for AT&T

why do people who DON'T have the phone act like they know what they are talking about.
Works fine on T-Mo, and ATT. you just miss out on some of the bands, and also carrier features like VoLTE.
my 930F works fine on Tmo. and it'll work fine on ATT as well.
