All of a sudden...getting Rogers 3G on x1i

OK, I must be dreaming! I looked at my x1i today, and I'm suddenly getting 3G/H. Until today, I've always only had Edge.
fieldtest.exe band shows 255:unknown
Ran speed test from dslreports.com using Opera; showing 1124 kbit/sec for a 1MB file test. Ran again with IE and got 1190 kbit/sec
I know the hardware specs on the x1i don't match up with Rogers 3g network, so did Rogers change their network recently?
This is an unlocked x1i with Generic UK ROM 1.05.931.10 R3AA010
I'm in Aurora, Ontario (north of Toronto).
Anyone else seeing this?

Rogers rolling out 3G on the 1900MHz band or you have an X1a.

I've had this x1i since December. So does anyone know if Rogers is changing, and has anyone else suddenly seen 3g?

I started noticing the 3G symbol about 2 days ago myself here in Toronto, before that it was 95% of the time E and sometimes just G. Now its 95% 3G and its unusual for it to go to E anymore. No idea though on benchmarks since I don't have a Data plan at the moment and so I only use it when I really need to. Will see if any friends have a data plan though and don't mind me borrowing my SIM for a few minutes and giving it a try, because I'm curious now. Getting the 30 fps VGA recording and 3G locally - that'd be awesome .

Thanks, pdamouse. This gives me hope that Rogers has changed their 3g network, and that I'll now finally have a really cool phone.
Anyone else seeing the same thing?
Anyone have a tech contact at Rogers that might be able to confirm?

maybe you just passed by one of the very few 1900mhz towers

Called Rogers tech support earlier; the rep I spoke with had no idea, so he asked a colleague. The colleague apparently said they now support all 4 frequencies.
The colleague was on a call, so I couldn't get any further info.
So theoretically, I was told that Rogers is now running 3g on 850, 900, 1900, 2100 mhz.
I have not been able to find anything on Rogers' site to confirm in writing.
Anyone else able to confirm?

Aha! Think it may be related to Rogers introduction of the HSPA+ ROCKET™ MOBILE INTERNET STICK
See: http://your.rogers.com/Store/Wireless/products/rstick_info.asp
Specs there indicate:
Technology: HSPA+/EDGE/GSM
Frequency:
HSPA+/UMTS 850/1900/2100Mhz
GSM/GPRS/EDGE 850/900/1800/1900Mhz
Data Transmission:
HSDPA – Up to 21Mbps downlink
HSUPA – Up to 5.76Mbps uplink

Great I am not the only one that noticed this. Last week I was walking to the subway and noticed 3G and H on my phone. I was blown away! I spent the weekend downtown and had 3G/HSPA everywhere. Couldn't do a speedtest but it was definately faster than EDGE.
From what I noticed, downtown Toronto now has 1900 3G but as you leave the city towards Mississauga you go back to EDGE.

Got the same situation on last Friday when driving at 401 and 404. But didn't get a chance to test the speed before it jumped back to EDGE.

I'm getting 3g consistently in Aurora and Newmarket. Better in some areas than others.
Also noticed 3g as I was coming down the 404.
Now in Pickering, and it's completely back to edge.

ok wtf, i bought my phone from rogers, and i've been getting 3G and H for a month now, but i just checked settings->device information->identity and under model it says x1i not x1a. anyone else noticing this? maybe because of custom rom?

from http://forum.xda-developers.com/showthread.php?p=4579528
go into Settings, System, Device Information. Select the Hardware tab. Beside the first entry, CPU, you'll see one of two things:
"QUALCOMM(R) 7200A" means you've got X1i
"QUALCOMM(R) 7201A" means you've got X1a

lol I live within 200 meters of where those highways meet (404/DVP and 401) - that might be why I've been seeing 3G on my phone 100% of the time I'm at home. I never thought being this close to the busiest highway intersection in Canada would help me get better cell reception - but apparently it does .

Lucky you. The 3G signal disapears at Finch, so I still can only get EDGE at home. Hopefully more towers will be upgraded soon.

Today I managed to stay in place long enough to do a speed test.
I got 2.2mbs down and 0.65 up. Not really mind blowing but I was in a building and wasnt getting full signal. Also, there is 3G in north Mississauga, it's weird.

Sorry man, I'm sure they will be adding more towers - the area is expanding quite quickly. I was suprised at getting the signal more than anything, and someone mentioning right where I live as the place they see it - I way way over use the : P smiley...

wait a second here
This thread doesn't make sense - I have read elsewhere that the X1a and the X1i have identical cell frequencies.
To confirm, can someone with an X1i do the following:
Go Start > Settings > Personal > Phone.
Select the Band tab.
The second drop-down box entitled "Select your GSM/UMTS band" should give the following options:
Auto
GSM(900+1800)+UMTS(2100+900)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100)
Those are the options I get on my X1a, purchased directly from Rogers. Aren't those the options on your X1i as well?

I actually get this on my X1i:

UMTS(2100+800)
But we are discussing 3G support and HSDPA - they use different frequencies for that here as opposed to Europe, and the X1i uses those European Frequencies, while the X1a is specialized for North America. The GSM Quadband is a given that it will work everwhere there is GSM - but the 3G bands are not universal.

Sprint iDen 800mhz -> Sprint CDMA/LTE 800mhz and the One

So, according to HTC.com and Phonescoop.com, the radio for the Sprint version will have 1900mhz LTE, just as with the HTC Evo 4G LTE. Sprint is supposedly rolling out 800mhz LTE (former Nextel iDen) in the 2nd half of 2013. Question is, can the radio be modified via software to have 800mhz LTE, or is this a hardware issue?
Anyone know?
Thanks!

What a mess most of their customers will have, IMO stupid decision. Most people to use this network will need to replace their phones, and it means for you, that you have a decision to make on your LTE future, one which phone you buy or change provider, second option probably the best.
Please note that the Snapdragon 600 chipset does not have any modem support on chip, therefore additional hardware radios are added per requirement. HTC should have gone for the Snapdragon 800 which has a modem that supports LTE as well.
And in short, no you can't just change, it is hardware. However, towards the end of the year hopefully all phones will start to use the Qualcomm chipset announced yesterday which covers all bands worldwide.
HSPA/WCDMA:
Europe/Asia: 850/900/1900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
LTE:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

Re: Sprint iDen 800mhz -> Sprint CDMA/LTE 800mhz and the One
Ok thanks for the clarification that's what I was thinking. Perhaps Sprint will go ahead and pre-load the LTE radio for the former iDen 850 spectrum, and activate it with a firmware update. That's all I can hope for I guess.

Very interesting. Not sure what is going on, also not sure if HTC has any clue what is going on. There website is obviously wrong or not up to date. Still doesn't list 800MHz in US.

Looks like the One will only have Sprint band 25 LTE (1900). At least from the FCC figures.

SVDO is also missing, so no simultaneous 3G and voice. Understandably, though, with the LTE network increase.

Have gone from S1 to S2 with sprint, might go with HTC One instead of S4.
Does only one band of LTE on the phone mean there could be some towers that use the band not included in the phone, so I would only get 3g?

Do you have problems with Sprint now? are you using LTE currently?
Your LTE coverage will only be as good as how many 1900Mhz towers Sprint has around. If sprint doesn't have a tower in your phones range for LTE then you will only get 3G
If you travel a lot with roaming, then you will most likely want the AT&T model which covers most of greater America. If you get LTE while roaming will depend on Sprint and other Carriers agreements, otherwise yes your option will be 3G.

Thanks, I wasn't sure if their towers would have both bands or just 1, I wasn't sure why the phone only having 1900Mhz would matter.
I don't have an LTE phone, but I do have wimax coverage in Daytona, LTE is supposedly on the way. My work forces me to travel a lot, don't get to use 4g much anyway, I'm heavily dependent on roamcontrol, with a hacked PRL I make due with us cellular's 3g usually. When I am in Houston/Daytona I would like my LTE phone to have proper coverage though ;P

LTE coverage is great throughout Houston. It gets weak and sometimes drops to 3G when in buildings though.

Yes you are thinking correctly, however Sprint's 1900mhz is pretty comprehensive, in fact, I believe Sprint has more 1900mhz spectrum than any other carrier (hence why Sprint used to be 'Sprint PCS', referencing the PCS 1900mhz band), and far more 1900mhz spectrum than the old iDen 800mhz. You should not have any problems whatsoever.

Ill just be glad when they roll out 800mhz 3g..which this phone does have suport for. If they finally get around to upgrading the 3g here in Houston then I wont mind as much when the connection drops down. As such, the way it is right now, 3g is nigh on unusable, and sometimes so is 4g.

It has nothing to do with the modem. The One has a separate Qualcomm MDM9x15 modem which is not that much different than the modem that's integrated into the Snapdragon 800. It has plenty of ports which could handle another LTE band if one could be "fed" to it.
The issue is the front end RF stuff. Due to the uniqueness of the 800MHz LTE band that will be used by Sprint, it's difficult at this point to source the necessary antenna switches and transceivers and other front end RF components that will handle that specific 800Mhz LTE band.
My guess is that you won't see any ESMR800 LTE phones come out before Q3 or Q4 and it's also probably at least six months at this point before Sprint starts to deploy the technology commercially.

They are not going to roll-out EVDO on 800 MHz, only voice/1x, and a 5x5 LTE carrier.

That is not what I have heard from multiple Sprint reps about EVDO on the 800mhz. I was told, very recently in fact, that the voice/EVDO would be rolled out to the 800mhz, well before any LTE bands were activated in that spectrum. That Sprint was pushing for better penetration for voice and EVDO signals through the 800mhz spread, and that LTE would be focused on the 1900mhz for the time being.

According to this article:
http://www.lightreading.com/sprint/sprint-to-dial-800-for-lte-in-q4/240153521
"We expect to deploy LTE on 800MHz in the fourth quarter," said Steve Elfman, president of network operations and wholesale at Sprint on the call.
Nonetheless, Sprint is clearing the way for LTE integration with WiMax partner Clearwire. Hesse said he expects Clearwire's fast 4G service to start arriving late in the third quarter with "TD-LTE, multi-band devices."
With so many different chunks of frequency to support, Sprint will need these devices to switch between 2.5GHz, 800MHz and 1900MHz to get around the network.

That's not that unusual and really not that big of a deal for the the radios to handle in the upcoming devices.
In any case, working with multiple bands is fairly commonplace. Look at Verizon and AT&T for example which operate four different bands.

Wow
This has to be the most technical thread I have ever read Where do you folks obtain all this knowledge?

WiMax > LTE?

Will most areas with Wimax get LTE? I didn't care too much about this until I read that AT&T Ones get both Wimax and LTE. How exactly does this work? Has it to do with the GSM/CDMA thing?
I was with T-mobile before and you could say I was spoiled by their HSPA speeds. Now its normal for me to get anywhere from 80 to 100 kbps with Sprint. Occasionally I get an LTE signal and speeds upto 1.5 mbps. Would I get faster speeds if I had an older, Wimax phone?
Also, I was told by the Sprint rep that the Nextel towers will be converted to LTE. Is this true?

Where'd you read that att models support wimax?

It's magic, considering ATT never deployed wimax whatsoever. Sprint is the only major cellular provider who went with Wimax, everyone else went lte or HSPA+

All of this is true except AT&T ONE getting WiMax. As was said, AT&T has never had WiMax and the ONE is not capable of it. Whoever told you that is either mistaken or lying.
Depending on where you are WiMax could be more available then LTE as of right now. As they shut down the 800mhz Nextel towers, Sprint will be rolling out LTE 800 on those is the story most have heard.

I'm in Chicago and we have a lot of wimax. But also a lot of lte too. I did get faster speeds on wimax, but I could only get wimax if I were outside. So... I kept it off and only used wimax if I really needed it. It was a major battery hog.
Sent from my HTCONE using xda app-developers app

I had og Evo and Evo 3d which were both wimax phones. The signal was much more consistent than I get on my Evo lte and HTC one. As far as speed, I HAVE spiked to 22mbps once or twice on lte but I have to be right there in that sweet spot which is on the side of a major hwy. I can pull 5-8 mbps on an average lte signal but I am constantly loosing it and switching back to 3g and going back and forth. My wimax signal was a goo 7-8 inside my house. Lte is very inconsistent and my area is suppose to be over 80% complete I think last time I checked.
And like gk said wimax was a battery hog. I could never get half a day if I left my wimax radio on and off the charger. My lte devices last a lot longer. This one I take it off the charger in the morning and still have half battery at night most times

I would be surprised if it were directly true. The Nextel towers were all IDEN-based and are in the process of being torn down. I have no doubt they will be eventually switched to CDMA/3G and then LTE (or maybe built with LTE from the get-go), but probably not until after Sprint rolls out LTE to its existing tower infrastructure.

Not to go off topic too much but when I lived in Columbus Ohio we had pretty good wimax coverage. And in complete honesty the battery hit was hardly any worse than 3g so I would leave wimax on all of the time. I could go a full 12 hour day at work on my 3d with moderate usage and get home with 30 percent left. Similar comparisons in battery life on my 4g, shift, and et4g as well. Apparently its similar to any other signal issue.... But if its a good area wimax doesn't hurt the battery too bad at all really.

I used to get really inconsistent lte a month ago. I'm not sure if they improved the network to correct it or what but when I unlocked the bootloader, I saw a very consistent experience. Not sure if wiping everything did something to correct it, placebo, or new towers were flipped on the same day.
But I only get 2-3 mbps on lte
Wimax I was getting about 8-10
In any case... Sprint is the only major wimax carrier in the USA and att doesn't use it - as mentioned earlier, OP was lied to about this.
Also, I hear the Nextel iden network will be configured to lte on 800 mhz which our phones don't support. None do at this point actually.

wimax is awful & I live in a "good" wimax area. Besides Sprint quit building on the network once they realized it sucked.

All right thanks for the clarification guys. I was suspicious when I read it (no idea where, some random forums). Since Sprint is letting go of Wimax and replacing their Wimax devices with LTE, would it be safe to assume that places with "Best" Wimax coverage and/or Nextel coverage will get LTE at some point (6 mos-1 year)? It's really sad when it takes 30-45 minutes do download Cut the Rope at the local mall (in silicon Valley).

Sprint lte (any carried for that matter) is very signal dependent. Stronger signal = faster connection. If u connect to lte and its a slow connection, chances are you are connected to a site farther away then u think, or have a site (one that serves your voice coverage) between the lte site and your phone. All sprint sites are being converted to lte. Most Nextel sites are not. During the conversion, sprint is putting up panels has house both voice and lte on 1900mhz, voice on smr800 and lte on 800smr. No 800smr lte devices are out yet, will will be starting this fall. When Nextel is turned off (last day of this month), sprint will start turning on the 800smr on voice and lte but may take some time (especially lte side). 800smr voice is already being broadcasted in parts of the county, such as in Chicago. Most if not all native sprint coverage will have lte by this time next year. For much more info, go to s4gru.com

It wasn't so much wimax sucked based on the symptoms you described, it's the frequency Clearwire was using. They used 2500 mhz for wimax and if it were lte on that same band, we'd still have poor building penetration and weak signal.

the htc one should actually be capable of 800smr lte with some changes to the radio config (and possibly radio software too, but i'm pretty sure that won't be necessary)... once 800smr lte is up and running somewhere near where i live i'll be able to test and figure out what exactly needs to be done to make it work.

cdma band class 10 is 800smr. both antennas work for 800smr. the radio can transmit and receive on 800smr frequencies.
it's very likely that a simple configuration change will enable lte on 800smr. if that turns out to not be the case, it's definitely possible to do it by modifying the baseband software.

I asked Sprint support about a month or 2 ago if the One would be compatible with 800 when they launch it and they said none of the currently released phones are capable and none will be released until Q3 or Q4

Note that by the time Sprint actually deploys in large-scale any non-1900mhz LTE, you'll be up for a new phone (that is, 2 years). It's going to take a long, long time. They haven't even started yet.

that radio (antenna) will not work on 800smr LTE. Voice 800smr yes, lte, no
The Sprint version of the HTC One is limited to band 25 LTE 1900. It does not support either of Sprint's upcoming LTE bands -- band 26 LTE 800 and band 41 TD-LTE 2600.

***THIS IS LIKE THE OLD "WILL MY WIMAX DEVICE WORK ON LTE" DEBATE " lol ....we all know how that ended up

LTE not working on Sprint (Fix?) [11/16]

The following is my understanding of the problem. If any corrects or updates need to be made just post and I will update the OP.
Many N5 users are on Sprint noticing that they are not connecting to LTE. The key here is that the N5 is a single radio Triband LTE CDMA device. There is also a great post that explains everything here (thanks LordLugard) and technical pros and cons as well as nice information on the current state of the network are on post #8.
From the s4gru post:
In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.
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 or text 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/texts on its own. It is just using LTE data happily. However, what if someone calls or texts you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call/text 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 or text on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If it is just a text, the data session is only interrupted for fractions of a second and is likely not even noticed by the user...
...much of Sprint’s legacy network either doesn’t support Circuit Switched Fallback or doesn’t support it in cases where the legacy network equipment is by a different manufacturer than the new Network Vision equipment.

So in other words your N5 cannot get phone calls and texts when using LTE while on old crappy legacy towers so it keeps you on 3G.
Warning, I am not responsible for any problems following this advice or code causes. In fact I suggest you stop reading, close your browser and never come back to XDA.
But wait there's a fix!!!
Well not really... but kinda. Type *#*#4636#*#* into your phone dialer and then go to Phone information. From here you can set preferred network type. Choose LTE/GSM/CDMA auto (PRL) (in rare cases LTE only (PRL) maybe required). Now you will auto connect to LTE if it is available. The problem is that if your on a legacy tower you will not receive texts or phone calls when on LTE. It's easy enough to switch between LTE/CDMA auto (PRL) and LTE/GSM/CDMA auto (PRL) on the fly but that's no solution, it just builds the hatred in your blood.
Update - This app is not needed but will be left up. See update 2.
I've built a really simple app to help with this. All the app does is put the above code into your clipboard and launch your dialer. You can then just paste and it will launch the Tester/PhoneInfomation of your phone.
Full source here. The apk is also in the repo.
Update 2
No Dialer codes need. Just install this app and it will launch the activity you need. Credit to DMX31 for posting this link I this thread.

I haven't had any issues so far with LTE (sending texts, making and receiving calls) on my Nexus 5 and i'm in a spark launch city.
I'm not even going to pretend to understand half of what's being discussed because I don't care enough...

I have a lte tower right by my house and can't conext to lte on my n5. 4 other phones connect just fine cause it's a strong signal. Called sprint and they said it's a known problem. This is ridiculous. If it's not fixed by my 14 days it's going back. Can't stand not having lte

This problem effects me, so bad to the point I just sold my N5 and went back to my CM S3. Kudos if you're not having issues, but lots are. The hours on tech support and browsing forums searching for a fix is not worth the effort over a piece of plastic to me with no ETA on when all the towers will be upgraded. Probably months out in my particular area. Happily chugging along on LTE again, maybe I'll try the nexus again next year.

Wait of the n5 is single band lte and sprint is changing their phones to single band to. Shouldn't this be a problem soon to go away?
Sent from my SPH-D710 using Tapatalk

It's only a problem in some markets. No issues where I am, for example, but in Chattanooga where I will be moving, the towers are only 4G accepted, not 3G/4G (from what I hear). This problem should be going away for anyone in completed 3G markets soon, and for markets that are not 3G accepted, Sprint should be ramping up the pace of the completions through vendor incentives.

I think that the key is them updating their towers. I don't know about where you live but that doesn't occur quickly in Raleigh North Carolina.

The key is Network Vision 3G upgrades so the phone can talk to the eCSFB side of the network. Incumbent vendor regions that are mostly not affected are regions where Alcatel-Lucent took over Lucent and Ericsson took over Nortel. Those should be fine and if there are issues then it's really just a software update on the cell site.
In areas where there's non-incumbent equipment then it's a big deal. Areas taken over such as Motorola will have an issue. Then there are the Samsung vendor regions.

Every Samsung region is a non-incumbent region (except PR/VI) and are guaranteed to have issues because Samsung is replacing Nortel, Motorola (hard handoffs known for a while - see Chicago), and etc. According to the document I'll quote below the only mitigation for the eCSFB gaps are to actually quickly complete the network rollout / conversion and fire up NV 3G as soon as possible so Tri-Band devices can actually talk to the LTE core and 3G side.
Explains the apparent "lack" of work in Samsung markets but a huge number of sites physically completed. No time for acceptance / integration when you must complete as many sites as possible to mitigate the eCSFB gaps.
Sprint eCSFB Gap Issue Legal Approved Talking Points:
eCSFB Gap Talking Points
Sprint’s Network Vision Plan (Spectrum)
Sprint’s Network Vision plan includes access to three spectrum bands, (1.9, 800 and 2.5), and LTE handsets with a single radio.
Access to diverse spectrum assets allows Sprint to maximize capacity and coverage.
Current Sprint LTE Devices (2 Radios)
Current Sprint LTE devices are Simultaneous Voice and LTE (SVLTE)—using two radios, one for voice and one for LTE data. This allows CDMA calls and LTE to operate at the same time.
Dual Radio SVLTE devices can degrade the user’s quality of experience – two antennas may slow throughput at the cell edge and reduce battery life.
Future Sprint LTE Devices (1 Radio)
CSFB and eCSFB (Circuit Switch Fall Back and enhanced Circuit Switch Fall Back) are features that enable single radio functionality in the handset.
eCSFB Benefits:
With eCSFB implementation, Sprint will be able to offer fast LTE data speeds and 3G voice supported on single radio devices. This provides a more cost effective option for Sprint’s long-term business plans to support additional spectrum bands.
eCSFB is expected to improve handset battery life compared to SVLTE.
eCSFB Gap Issue – What you Need to know:
Smart devices require eCSFB to “fall back” to 3G to accept a voice call if the user is connected to the LTE network.
All markets need to be upgraded with eCSFB capability.
eCSFB Gaps are only in non-incumbent markets where a site has 4G LTE and no 3G upgrade.
4G LTE integration with 3G is different by OEM type:
Incumbent markets – LTE 4G only sites can communicate with either legacy 3G or NV 3G sites.
Non-Incumbent – LTE 4G can only communicate with NV 3G sites; so individual sites need both NV upgrades.
LTE devices – Customer Experience
When 4G LTE is deployed in a non-incumbent market on sites without upgrade to 3G service, there is a gap.
Existing Devices – No Impact
eCSFB Devices – Phone becomes 3G only device
Non-Launched Markets
No coverage visible on Sprint.com maps but different experience for users with existing devices versus new eCSFB devices.
Launched Markets
Sprint coverage tools will display LTE coverage. For new LTE smart device users this could be confusing since they would expect LTE and 3G coverage with the device they purchased, but would not experience LTE until the 3G network is upgraded.
Mitigation plan:
New LTE Markets
When locking new LTE markets for announcement/ launch, eCSFB deployment status will be a factor in the analysis. New LTE markets will not be announced unless the eCSFB gap risk is low.
Complete the build quickly in eCSFB gap impacted markets.
Acronyms
CSFB – Circuit Switch Fall Back. It allows for single radio devices. (ERC)
eCSFB – Enhanced Circuit Switch Fall Back Next generation CSFB. (ALU, STA)
SVLTE – Simultaneous Voice & LTE. Allows CDMA calls and LTE to operate simultaneously
Incumbent – An incumbent market is one in which the OEM stays the same as before Network Vision
Non-incumbent – A market in which the OEM changes as well as all of the equipment.
ERC - Ericsson
ALU – Alcatel Lucent
STA - Samsung
NV – Network Vision
OEM – Original Equipment Manufacturer (ERC, ALU, STA)
Gap – 4G LTE on sites without appropriate upgrades to 3G service
1.9 GHz Spectrum - Provides initial capacity and coverage for voice and data services.
800 MHz Spectrum - Improves coverage and in-building penetration for all services.
2.5 GHz Spectrum - Increases data capacity to support higher data demands and more users.

^^this. To the OP, this is only a temporary problem, as it is not in Sprint's future plan to keep any markets in a eCSFB gap. This is just an unfortunate side-effect of the rollout not being finished.

Temporary yes but really what does that mean. I'm guessing maybe between 1-2 years? By the time it's fixed in my area I might not even have this phone any longer. Their network has been a mess for years and I'm paying good money for this crap.

Is this related to my data dropping completely by any chance? I can connect to 3G and 4G fine, but after a random amount of time the data connecting just disappears but I can still make calls and send texts.
The Nexus 5 is a great phone, but I'm finding this whole situation pretty frustrating so far.

I have not experienced that and it doesn't sound like the same problem to me...

The easiest way(for me) to toggle between networks is this app
https://play.google.com/store/apps/details?id=de.mangelow.network&hl=en
No dialer codes needed.

So here's something that's happening to me. I'll send a message and it'll be stuck on sending. BUT. If I place a call and let it connect then hang up the text will go through fine. I'm in Dallas and have LTE almost everywhere but my house lol. Sometimes i'll get LTE upstairs at my house.
I can also remember doing this on my Evo 3D around September-November 2011

When I go into *#*#4636#*#* and force LTE Only in Phone info, the radio indicator in the notification area shows me as having four bars of LTE, but the Current network indicator stays in the Searching for Service state and never progresses past this point.
I am however, able to run a ping test on that screen, and while both the "ping hostname" and "http client test" pass, the "ping ipaddr" test fails with "IP addr not reachable".
Is this what others are experiencing as well in markets where you have to force LTE?

Great work. Should be useful to Sprint users.

You can skip the computer part if you install logcat and begin at step 5 after launching.

Wouldn't battery use increase from enabling this? Because it would be constantly scanning for the other 2 frequencies?

True enough, but you need to get the right logcat app, some don't work as well as others. I initially tried aLogCat, but didn't seem to work. CatLog app worked great, however.

Just saying. No one has been able to get a B41 (TDD-LTE 2496-2690) connection with a Nexus 5 and that's with actual maps of Clearwire sites that's been upgraded and knowing where each site is located at. I've personally visited over 24 sites to no avail and know of others that visited many sites as well. Looks to be a much bigger issue than just changing up the LTE Engineering settings and may be network related.

Just got the phone but I'm pretty disappointed with the LTE speeds 1/2mb down, outside it's a bit better. Went downstairs and it disconnects from LTE altogether. Anyone know if it's a radio (hardware) issue with the phone or firmware radio? Some spots of my house won't even catch LTE, whereas my s2 would get wimax.
I've tried spark but it makes my connection more unreliable more pocket loss, but indeed it does seem to make it faster, placebo? I'm in Los Angeles don't know if it's been rolled out. I tried updating prl/profile to no avail. My next choice would be to try the LG 2 in hope of it having a better radio.
GPS is spot on, and wow this thing is fast!

Just a question, but wouldn't prioritizing band 26 make more sense since that is the 800MHz frequency band?

No, band 41 has the most capacity so you would want to connect to that if you are actually in range of it. It will automatically drop you down to the lower frequency bands as you move out of range of the higher frequency bands.

Hello, I tried this on my N% for Sprint today. btw. I live in N. OC, near Los Angeles. If I happen to be in and out of spotty LTE coverage areas. Will these adjustments cause more battery use or or worse performance?
When viewing HD youtube videos, it seems to play smoothly for a while, and then pauses as it the speed is going and up and down or being throttled.

About Band 41
So you means the Band 41 is unopen under default setting?
we need to open it by manual?
You know, the biggest mobile carrier China Mobile's 4G is TDD-LTE, and also use the band 41
But if I use the 4G sim card, it still work in 2G.

I am with uh60james spark seems to offer more throughput and less disconnects.
I drove to Corona from Carson the other day and i was shocked how much coverage sprint has improved on. I wasn't able to stay connected to LTE on my the entirety of my drive but it is impressive how Sprint has extended lte coverage around corona at least on the freeway.
Spark works better for me, less drop offs.

I am in Naperville. Will check this out and see if tri band goes this far out west from chicago.

I haven't heard anything about DFW having Spark anytime soon, so more than likely not. I live in Arlington myself, and would love to see this area Spark-enabled sooner than later.

Enabled this on my n5 a couple weeks ago .... dismal speeds on lte in downtown Los Angeles as usual around 4 down and 2 up.... Yesterday for the first time spark kicked in and I got 44down and 14 up. BUUUUT today its back and slower than ever. around 2 down/1up on LTE

Seems that due to Nexus 5 lacks TD-SCDMA for China Mobile 3G, it is very hard for Nexus 5 auto connect to LTE.
You need *#*#4636#*#*, change mode to "LTE Only" and wait connect to band 41/38 cell and then change it back to "LTE/GSM Auto (PRL)".
After it, you will on LTE until one of following happens: no LTE cell signal; incoming call; make a outgoing call. If fallback to GSM, you will need another round of "LTE Only" settings. Please check some chinese forums, there are plenty of guides.
It seems N5's baseband firmware did not implement some directly GSM to LTE function and do not support China Mobile 3G, so ...
