Understanding AT&T 4G...

Time to teach an old dog some new tricks. Being an AT&T customer for over 10 years it should come as no surprise that I'm an absolulte stranger to 4G . I have few questions though and hope someone can steer a little 4G knowledge my way.
1) When 4G hits will we need to be on a stock rom and radio?
2) For those of you already in HSPA areas (lucky bastards) what kind of speeds are you experiencing.
Thanks in advance

I think when 4g hits all we will need is a new sim card but I could be wrong

ATT runs hspa+ as "4g", which will go to 21Mbps, then 42Mbps. Then ATT will roll out LTE as real 4g soon too, which will be a whole new network, new frequencies, and need new phone hardware antennas and radio. LTE speeds can go very high, talking about 100Mbps eventually.

I think the sim card stuff is hokey. I'm more worried about custom Roms and radios. Like will we be able to run CM7 when 4G drops.

Yep we will need a lte phone and 4g sim. HSPA + will work fine on different roms. Dallas has it and ive gotten speeds over 6 dl. Stock radio and custom rom.

That's the feedback I was after. 6mb, nice!

Well ATT's current hspa will be able to go up to 42Mbps when they turn it on. Look at current t-mobile speeds, its the same technology and they run 21Mbps with users seeing 9Mbps in select areas, and higher. So same applies to ATT.

I am in southern california, supposed "4G" coverage area; only get between
500k to 1.5mb/s. Stock rom and rooted, same result. Att blows.

thats my next step. I am using TPC optimized stock rom, which should have some build prop edit to it already, but will try to tweak it some more and see the reaults. I doubt I will see anything over 3mbs....

Chicago here, I get 6 down and 1.5 up on non-peak data times. I don't think the sim card is a non-issue considering that hspa+ is just an evolved 3g technology. I can't wait for a more consistent speed, even though I use wifi most of the time. I am using cognition hd right now and still getting these speeds.

Getting + speeds or not.
ok...i cant post pic from my phone here. But my average was between 5 and 6.5 mbps. Slow uploads though. Nothing higher than 1.5.

Those are excellent speeds for this phone. You are on HSPA+ for sure, otherwise you'd be getting less than 1-3 Mbps down/0.5-1.0 Mbps up if you were on 3G only.
Also your phone should say "4G" right in the status bar, which is what T-Mobile calls HSPA+.

I didn't mean the lame comment but I knew it would get me results. I do average between 4 and as high as 11 mbps so the speeds reflect hspa+ I just assumed it would say hspa+ not hspa in my settings.

This is the expected behaviour. He was talking about the label for "4G" or HSPA+ in settings. HSPA+ is simply T-Mobile's version of 4G. Which, for what it's worth, isn't technically 4G.

The status bar indicator isn't accurate. Side-by-side, my G2 with Mobile Signal PRO shows 3G while the G2X never moves from 4G. Mobile Signal PRO never registers anything above 3G on the G2X which is weird. I have friends that use it on Samsung and HTC phones and it's always spot-on and it's always been accurate on my G2. I think there's something funky going on with the LG radio software.

its propably not fully optimized for the g2x yet

It works on a friends P990 in the Netherlands so it must be specific to the T-Mobile version of the radio. I e-mailed the dev to find out what's up.

There will not be an H or H+ icon... its 4g... hspa is too many letters for the general public to deal with...
Also, Phoenix does not have 4g yet however I am getting the 4g signal when i am on UMTS.. YOU DONT FOOL ME TMOBILE! I am pretty sure there is not even a 3g icon on our phones, anyone wanna get into the files and look? I am on campus and cannot check this but I think it would be funny if they did not even install a 3g icon lol

explain to me why i am only getting UMTS then? I am freaking sitting on campus right now...

cuz asu is gaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay

Does anyone else lose 4g a lot?

I've tried WCDMA Preferred and GSM Auto (PRL) but I am constantly losing 4G switching back and forth in areas I have never had a problem.

Download the app called 'Network' in the Android market and set it to WCDMA only.

That isn't a solution but why wouldn't I just set it in the testing mode? Why download another app?

I lose 4g often too....and I go down to 2g....what happened to 3g? My old prepaid Cricket phone had a consistent 3g signal all over Tucson, while the 4g is really fast, it isn't reliable, and almost (almost) makes me wanna go back on cricket.

this radio is garbage.
my g2 was piss poor with 4g and this one is even worse.
I can watch it sit on the table and go from full bars of 4g to 2 bars of 2g/edge and STAY there.

sorry for the uninformed question, but is this something that can be fixed in a new rom, or mod?

I added data tweaks to my roms. I don't have any issues.

It's not the radio. It's more likely the 4G signal in your area. I am in Atlanta and I have full bar 4G almost everywhere I go. At home it will drop down to 2G but I have wifi there.
As for 3G, this is a 4G radio. We're you joking about the 3G expectations?

Point #1 - You are incorrect. I am saturated with T-Mos "fake" 4G coverage and have never had a phone drop it like this one does.
Point #2 - What are you asking the other posted about 3G expectations. This phone doesn't have a 4G radio. T-Mo doesn't have 4G. They have 3G that they market as 4G.

Everyone has "fake" 4G coverage. LTE isn't technically classified as "4G" either, the specification calls for rates of at least 100/mbps. T-Mobile currently has faster and more widespread pre-4G coverage than any other carrier, and the phone does have a pre-4G radio. The phone does support HSDPA at rates up to 21Mbps, and does is in fact have a pre-4G radio. And as far as my other comment not being a solution, have you tried it before bashing it? I've had plenty of luck with that solution personally and I figured it would be kind of me to share, but I suppose I stand corrected.

Yes. Thanks to your roms, I have signal in places I never had before (like the bathroom at work. I can now surf while doing my "business" and important "paper work" in my "office", ya know.?
while i poop.

What are data tweaks?

I have noticed like the iPhone 4 that if you touch that metal peice on the back around the camera the signal drops. I got a case that covers that up and that fixed all my 4g signal problems. My phone stays on 4g most of the time where I am. The T-Mobile network where I live works very well though.

If you are on the tmobile network, you can't get 3g anymore if your phone is a 4g phone. It's either 4g or 2g.

have all HSDPA towers been upgraded to HSDPA+?
Or does the phone just recognize all HSDPA as '4G'?

It recognizes all HSDPA as '4G', I have full signal in certain areas with a '4G' icon but get speeds around 1Mbps and when I check the actual signal with third-party apps it is registered as HSDPA.

i think u guys got bad apples cause i always get 4g an my friend wit the same phone has 4g all the time

Are our captivated getting 4g speeds (not Lte)

So I am on cm7 and it says h in the too corned and sometimes 3g. On stock it only says 3g. Does that mean on certain roms you get 4g speeds and on others you don't?

No. The captivate won't ever be able to use 4g. The hspa network is pretty much the same as 3G.

Technicaly the 4g speeds are that hspa thing I thought. Isn't Lte something different?

No. They are different. Imagine that hspa+ is faster than 3G but not 4g so it's more like 3.5g. It is faster than regular 3G but your phone still doesn't have the hardware for the 4g network.

AT&T is calling their 4G, 4G, but technically there is NOTHING running 4G. For AT&T, 3G is capable of HSDPA(Download). 4G is the addition of HSUPA(Upload).
For our Captivates, specifically custom ROM's. Captivate based ROM's do NOT have HSUPA. i9000 based ROM's DO have HSUPA.
To answer your question, CM7 is a i9000 ROM and is running "4G"
And yes, LTE is something completely different

thanks kang for not making me say all that.

Thanks to both of you for clearing things up haha. I really appreciate it.
Sent from my SGH-I897 using XDA App

The AT&T roms don't make any distinction between HSDPA (which shows as "H" on CM7) and UMTS (which shows as "3G"). So on an AT&T ROM you will only see "3G". Both are 3G as far as AT&T is concerned.

The new "official" Gingerbread leaks for the Captivate all say H+ in the corner instead of 3G as well... But the speed is the same.

I think only KI1 shows that. The ones released after it show regular3G.

That's not true. The new leaks still say H+

I don't care for at&t's false advertising there fake 4g. On my HTC Inspire, the stock Rom will only say H+, E, and i think I've seen G. No 3g . Its say H+ regardless. Even If your on a 3g signal.

[Q] 4G icon for CM 10.1

Using the latest CM 10.1, I noticed that my phone says "H" for the connected network, even if it is HSPA+ / HSPAP. Now, this doesn't bother me over much, but I really would like to change the H icon to "4G" when I'm in an HSPA+ area, and "H" or "3G" in a non HSPA+ area. I hope that makes sense
