n4 Switching from 3G to HSDPA

I'm with t-mobile and i always have my connection on 3G but only when i use the internet shows h ans 2 bars. Can someone confirm if their nexus 4 does the same out is just that mine is defective

The nexus 4 only switches to HSPA when you use the Internet, in order to save battery.

Majorly annoying feature...it should at least give a 5 second window before switching back. Latency is ridiculous with the constant handover

Ditto bro, super annoying feature

Sometimes, it doesn't switch to HSPA+ and the bar stays on 3G when I use the internet, but when it does I don't get any connection.
I don't get anything over "E" either when I force 2G in the settings.
Because of this, I only have access to T-Mobile 4G but nothing else. I would like to use their 3G or even edge when I am traveling in the rural areas and there is no HSPA+ available. Does anyone else have this problem?

Its as a test to see if I will get data over anything but 4G, since 3G (UMTS:3) yields no connection whatsoever. And by forcing 2G (yes I know is edge, duh) I wanted to see if it was only a 3G issue. But obviously its not, since it doesn't get anything either. Not even 0.01 Mbps.
Btw forcing 2G gives me EDGE, thus showing an E symbol. That's why I expected to get something over E when I force 2G
EDIT: nvm, got speeds over 2G (E). 0.12 up, 0.06 down
3G still having issues

See your word choice can be taken two ways. By "over E" you meant data being transmitted. I took it as you were expecting something more than E.

In that case they need to fix the technology. That's how it works you know...things get better by patching bugs and fixing anomalies. If it's causing unexpected negative outcomes to the user, it behooves the manufacturer to fix it. I'm not really sure why I even bother replying to you, if you can't figure out why things should be tweaked and settings changed, you're at the wrong site bro.

i'm having issues with no connection for a long time when I open up a game or something. I'd have to wait about 5 seconds or longer for it to connect. Therefore, when I open a game such as Wordfeud, it will say error, no connection, pause, then open the game up. Is there any way to change this? I don't mind a hit on battery since I have an external I carry with me. Thank you in advance.

Would it be normal to bounce back and forth between all three, Edge, 3g and HSPA?

You must have really crappy signal then for it to be going between 2G and 3G. Between 3G and HSPA isn't a big deal because that's by design as was said. Having active connection to the towers only ties up the limited number of channels on a tower plus kills your battery faster. If everyone held open channels on the towers, calls would be failing since they had no channels to connect to. I think it's something like 256 channels per tower or something. That's why tower density is important in big cities.
I'm on AT&T MVNO though and my phone stays on H the whole time (not dropping back to 3G). I've had that issue with my SGS2 and newer radios for it but the older ones would always fall back to 3G. There is a momentary lag when the device renegotiates a channel with the tower but in general it shouldn't take that long, maybe 3-5 seconds from complete idle. There's a half-way stage called DCH (or is it ACH) where it can jump back to actively sending data in 1/2 second but it only stays that way if the timeout of 7 seconds doesn't expire (if the tower you are connected to support Fast Dormancy it does 7 seconds, if not i think it's 30 seconds).

Yeah, it looks like I've got really terrible signal strength at my house, but still manage to pull 5mb down. My signal strength is around 100 at best. The only time it was punting me down to 2g was when I was first activating, but that hasn't happened again. Maybe it was just a new setup type of issue, and like all of us, one little thing goes wrong and I think the sky is falling.

It's normal for it to switch from 3g to hspa

T-Mobile LTE in announced markets

This thread is for pretty much anyone who has T-Mobile LTE in a market where they haven't announced it yet.
I live in Virginia Beach and saw today (surprised as hell) that I have LTE...

Cool, can you post a speed test.

I can confirm the Phoenix metro market got LTE on the turn-on date March 26th as expected. I went into the store on the 27th and ran a speedtest on one of the Note 2s in the store. I'll post a confirmation picture I took with my SGS2, but it came out to 33mbps down, 22-23mbps up on LTE. I'm waiting for the SGS3-LTE to come into my local store then I'm likely going to sell my SGS2 and take some money from my paycheck and buy the new T999L.

What's interesting is my Nexus 4 gets a drastically better LTE signal than my Note II. On average ~10dB better.

That is interesting because the LTE radio in the N4 does not have an amplifier connected to it like the Note II. Every report of signal quality for LTE on the N4 I've seen has been poor levels, functioning but poor. The Note II at the store down the street from me was working fine with full signal, I didn't get the detailed dB on it though. I haven't seen what the N4s look like out here with service, but now I might need to look into picking up an N4 to get the LTE service.

My note II averages -105dBm at my house while my Nexus 4 averages -95dBm. That's pretty significant. Again, this is LTE.
Neither phone drops it or anything like that. How do we know for sure the Nexus doesn't have an amp?

IGNORE ME I HAVE BEEN CORRECTED, THERE IS FULLY OPERATIONAL LTE HARDWARE IN THE N4! HOORAY!
There was a discussion after the phone was pulled apart XDA style and we first discovered that it even HAD an LTE radio (I remember the uproar when that was found, remember it's UNLICENSED (no FCC regulatory approval)). People noticed that there was no amplifier for the LTE radio but there were solder points for it. Based on this information plus the weak LTE signals people were getting on AT&T in most areas (-107dBm or less) everyone put two and two together to get that there was no amplifier built in. The amplifier is only really needed to enhance the reception to the tower, not from the tower (you can't boost a useless signal into a usable one if the antenna can't receive the signal already, it doesn't work like that), so as long as you're in the city, you'll have LTE without a problem as you're mentioning. The amplifier is enabled and used for transmissions when you're further away from the tower and the signal cannot carry as far from the chip's existing amp (typically weak) in order to maintain a two-way transmission. This would also account for the longer battery life that people are reporting on their N4s after they switch over to LTE primary. No amp means no extra draw against the battery as the GSM radio is only used as backup and for calls on T-Mobile (they don't do VoLTE). Typically a tower will not enable broadcast in a direction that there is no serviceable clients, hence the multiple vertical aerials facing 3 directions, and will cease to broadcast at full strength until it receives contact from a client device (power savings). Either your basic amp built into the chip is hitting the tower or there's other LTE users in your area and keeping the tower at full strength, either way, AWESOME.

Just to enlighten, the nexus 4 lacks no components to function properly on T-mobile's network, as a matter of fact it's fully functional on any band 4( 1700/2100mhz) LTE network. Check out this article and the Nexus 4 LTE Band Coverage table about half way down the page.

Yup, LTE 33mbps down, 23mbps up was tested at the T-Mobile store on Baseline & Rural in Tempe 2 days after launch of the LTE service in the valley on a Galaxy Note II in-store display model using Speedtest.net. Reports are mixed from the west valley that LTE is either not up or is spotty, and there is continuing tower maintenance to bring LTE online out there currently. (Lot of my friends are on T-Mo, we all love the service)

This is all great news I cant wait for the HTC one to be released.

[Q] Bad T-Mobile Signal, Anything I can do?

So, I have a Nexus 4, and T-Mobile ($30/month prepaid). I live in the south-western part of PA. I'm in my house currently, and have full bars, no problems there.
I was at work earlier (inside), and had no signal at all. Outside I have like 1-2 bars, sometimes. I'm in the same town too, and the area seems to be in a more elevated area as well.
When I tried searching for mobile networks, I did notice AT&T showed in the list, but not T-Mobile. Perhaps this means AT&T has better coverage in my area than T-Mobile? Is there anything I can do to improve signal on my-end, like flashing different basebands? I was on the latest (.48 I think) earlier when I experienced this, but I flashed down to .33 now. Still full bars in my house, but I'll have to wait till tomorrow to verify if it actually changes anything.
I like T-Mobile, so I would prefer to keep using their service, but I do need some kind of cellular at work :/ I don't think AT&T offers anything like T-Mobile's $30/month prepaid plan either, for that cheap anyway.
Edit: T-Mobile's Coverage map shows green for my entire town and neighboring towns, for 2G/Voice.

Had a Razr Maxx about 8 months ago, beginning to miss that part too. Can't use wifi because of the unsolvable multicast packet wakelock/drain. In buildings where I used to get 2 bars 4G with the Note 2 its now either 2 bars 3G or 1 bar 1X if I hold the phone at the bottom (where I think the radios might be). Needless to say I pay attention during the entire class period now.

Living on the edge of 3G coverage...when I say edge I mean 5 ft behind my house I would drop signal on most phones. 2 bars and no dropped calls or failed to send texts I would get with the old S4. So im getting great reception.

I spend time in a remote part of north Idaho. I get 1 bar of signal, no 4G, and limited 3G (instead of 1G) when I am lucky. I previously have chosen Moto phones because of the weak signal in that area. I bought a Note 3 fully prepared to return the phone in my 14 day window and swap for the Droid Maxx if necessary. I have been pleasantly surprised with the quality of the radio reception. It is on par with my previous Droid Razr. I have no complaints.

I've noticed my N3 gets poor or no 4g reception where my Note 2 got great 4G. I also noticed it would be on 3g when I know there's 4g in the area I'm in (e.g. highway), and I also found that if I disconnected data manually or made a call and disconnected (which also disconnects 3g), sometimes it would find and connect to 4G.
I hope this gets fixed in a radio update

Signal strength horrible
Just bought a note 3 coming from a droid Bionic and original droid before that. The signal in my building is not great but my Bionic rarely had a problem with 4g. The note 3 is dropping to 3g and I have even seen 1x (haven't seen that in years). Data doesn't work half the time at work and that is an issue. Since I haven't had a Samsung before does anyone think this will be fixed? I did the update yesterday and was hoping that was this fix but nope. I was tossed between the note 3 and the droid maxx( for battery life). I still have a week to switch (for a fee of course) but the phone is awesome. However I can't live with bad reception. Does anyone have a comparison with the droid maxx for reception?
Thanks for the help.

So that is in PA
BAD ASS NOTE 4

Been hitting 60+ in sw Houston area. 80 max. But consistently 30+ easily the last few days. Used to be 15-30 maxing out out at 40.

Southeast Hou. Im at 13-14

Honolulu here. 34mb DL. 12MB UL.

I live in Anaheim California which is on the list but am only getting 28.33 Download & 3.50 Upload, no difference from what I was getting when the Note 4 first came out

i would think this would help more with consistent speeds vs everyone getting higher speeds. Im sure if you are connected to the wideband lte you would see higher speeds during non peak hrs but i can definitely tell the difference in peak hours vs non peak hrs in ABQ NM. Ive seen as low as less than 1mbps down due to congestion and no, i wasnt throttled. Around 11pm, my speeds would jump up. It basically forced me to use my wifi at home due to such low speeds. Hopefully the wideband increase will help clear up congestion as the faster people load/download their data...the faster they can get through the pipeline allowing for a smoother flow. Considering youtube would stop qrtr way through the video due to buffering... i would hope this would fix some of those types of issues.

How do we know we are using LTA? Do you get a symbol on the phone? If so what does it look like? Screenshot maybe?

This is what I'd like to know as well. According to "LTE Discovery" I'm on Band 4 right now. The linked page shows that my city should be LTE-A active. My speeds haven't changed even a little. Mid-teens down, a handful up.

Do you have to update modems or something to get it? I've been rooted since new and never took any of the updates.
I haven't seen anything other than band 4 locally.
This is the best I've done in town, but only the downtown area gets 4 bars. I'm usually 2 or less around most of the town.. This is versus what I typically get around my house.

When you go into the service menu by dialing *#0011# on the first line you will see Band 4 BW: 15MHz. When you have a connection of 15, or 20MHz you are using wide band lte.

This is correct. This is like a 4 lane highway instead of a single lane. This also includes the lowband spectrum 700mhz it baught from Verizon which is band 12. Band 12 is what travels far and through buildings. You might even get signal in an elevator because of it.
