[Q] Why is my AT&T LTE increadibly slow?

Status bar says I have 4G LTE but 5mbs? I've seen other people well beyond 30mbs.. 5mbs seems more like HSPA+..

Probably just the area. My HSpa+ speeds are so erratic lately.. sometimes I only get like 50kb per sec its horrible.. att needs to step it up and upgrade the network.

Some ROMs take away 4g.. I don't know about the ROM you're currently on, but mine has said I have 4G when I was really limited to 3G. I know this isn't much help, but I've had similar encounters and it was the ROM I was running.

It says LTE:14.

Just wondering for those with good speeds, which baseband are you running? I'm on I747UCLH9. And I hadn't had high download speeds since I flashed it.

Is this 4g lte?

Sent from my SAMSUNG-SGH-I317 using xda app-developers app

No. But it's a good speed.
You can check by going into settings, about phone, status and see what network type says.

Example

Correct. Not LTE, but fair speed for H+, arguably slightly faster than the typical 3G. You're getting the speed I used to get when I was on my SGSII (non-skyrocket) until I upgraded to the SGN2 with LTE here in San Diego.

Thanks. Its says im running LTE:14. So I guess the question now is why am I not getting lte speeds!?
Sent from my SAMSUNG-SGH-I317 using xda app-developers app

Just ran another test, slightly faster speeds but you can see in the status bar it says 4g instead of h+.
Im running jellythunder perfect storm..which I thought h+ meant lte.
Ideas?

Ok. Than u are getting LTE. The rom u have just isn't showing show in your status bar.
Did u flash an international theme or something that may have caused this?

4G=LTE
H, H+ = HSPA (3.5G)
3G = UMTS
This means that when you are in LTE you won't see the LTE symbol but instead 4G.
Depending on the rom u are using of course. In order verify that your ROM is actually using LTE go System Settings --> About Device --> Status. Look under Mobile Network Type.

I am in a lte area and my status bar now says 4g which means lte. What are normal lte speeds? My last post was the speed test on the lte...that normal?
Thanks again!
Sent from my SAMSUNG-SGH-I317 using xda app-developers app

No, this is what it would look like. Look in between the alarm clock and the signal strength meter.

LTE = faux G as far as I am concerned.
AT&T is still on 3G .. its just 3G+. According to what I have read, LTE (and WiMax) was originally a "transitional technology." Then it was upped to 4G and HSPA+ is now a a transitional tech. Then some1 dumped a lot of money into an offshore account and transitional tech is 4G.
Cue the nerd rage at this point.
LTE Advanced (as well as WiMax v2 or whatever they were going to call it.) are 4G. These are some way away. With big V saying LTE deployment going into 2015, one could guess we won't see "pure" 4G until almost 2020.
Edit: LTE is 100Mb/s down AND up. LTE adv is basically gigabit. As far as the original spec, 4G = gigabit. So .. we aren't quite there yet.

Well, the symbol at the top left says H+. So, no that not LTE, if it where it would say 4G.

But if its an international port than it says 4g, jedi states so in first post

haha .. nothing like downloading (theoretically) a DVD iso in under a minute.

I'd rather have the lower ping time and the lower bandwidth connection than the higher ping time and larger bandwidth connection.
The fact that your ping is so low makes me believe that you might be on LTE. But it could be an excellent 3G connection or whatever ATT likes to call it to make themselves feel superior. I've seen speeds that low however for LTE when the signal isn't very strong.

LTE support in new update?

Can anyone with the new update please confirm if the new baseband supports LTE or not? Thanks!

The phone is already LTE capable, however T-Mobile needs to flip the switch 1st then we will get an update.

Not yet tmobile not ready 4 lte sometime in 2014
Sent from my SGH-T889 using xda premium

Or more likely 2013 depending in your area.
Hastily spouted for your befuddlement

Hopefully someone can find out how to activate LTE so that we won't have to wait til 2014 when the phone is outdated.

2014? Really dude....phone is already LTE capable and tmo is rolling out their 4G this coming year. Chill out.

Enabling the phone won't do crap until Tmo heats up their LTE mojo on the network. Patience grasshopper.

Not everyone who has the T889 is on Tmobile like you. The phone may have an LTE chip, but it's not usable... so it's not really "LTE capable".

Yes this. T989 will never run lte no matter what software is on the phone. We don't have the hardware for it. And the lte software package is there in general, for phones that have it.
And we don't have it.

Help with signal bar icons.

I have the GS4 from T-Mobile (obviously) and I recently flashed the Slimbean rom and it's great but when I turn my data on I sometimes get an H or a DC icon instead of 3G or 4G, and I also never had this happening in any Touchwiz roms. I've been looking everywhere for what it means and I sort of have an idea but is it bad or should I just ignore it? Any feedback on this would be great!

H is 4g.

Yeah thanks but I know that already, H is more of like 3.5G. What I'm more concern of is the DC icon. What does it mean and/or is it bad, anyway to fix it?
Sent from my SGH-M919 using Tapatalk 4

DC is DC-HSPA+, to my knowledge, dual HSPA+ (from two nearby towers I believe).

So with that being said, is DC better than H or 3G then?

It's possible to get better speeds out of DC-HSPA+ over regular HSPA+, however sometimes it doesn't make much of a difference.
