Carrier Aggregation (Sprint) - X Style (Pure) Q&A, Help & Troubleshooting

I've read that this phone is capable of doing CA. How can you tell if this phone is actually using it?
I work in Riverside, CA, which has CA active, but the speeds I get don't seem like they're any faster.

What is 3G (Noob question)

I hear its third generation, like faster internet, well I have t-mobile gprs, will it be faster?...
Like GPRS but instead of 10k speeds, u get 300-500k speeds (depending on your MNO). Naturally u eat up costs faster too...
Also allows video phone

Well, I have T-Mobile unlimited GPRS internet plan within the United States, so if I got this my internet would be insanely fast?
It only works if u r in a 3G coverage area. But yes, I'm using mine as a modem whilst out of the office, and it's not far off being connected to adsl. In my country I pay US$0.15/Mb which means u can hit a Gig without feeling any pain what-so-ever.
How could I find out if T-Mobile in the United States supports 3G?

actually thats not true, Cingular is rolling out HSDPA very soon, and that very close to ADSL speeds and you can also do voice and data at the same time, try that with verizon's EvDO, you cant because verison ev-DO stands for Evolution Data Only, s
HEy, imablackcat,
Tmo USA just unrolled Edge in many places, and will be expanding, and is shooting to have 3g in 4th quater 2007. Stop whining, USA is about 3 years or so behind the rest of the world in a lot of technology: cell phones being one of them. We can iether suck it up, or move to Europe......
Good luck!
EDGE won;t work on the JJ, nor will HSDPA I'm afraid.
HSDPA is sometimes called 4G - it's potentially magnitudes faster that 3G - easily 3Gig transfer rates - depending on MNO's allowed bandwidth.

I was under the impression that after AT&T merged with Cingular they then started rolling out UMTS this year. I think you can get 3G in limited places. Phone them and ask.

Sprint 3G speed in Los Angeles?

Anyone on sprint can comment on this?
What's the 3G speed in Southern California (LA and vicinity)?
I am coming from ATT and just wanted to compare the speed!
Orange county I get 700-1300 down about 300-500 up.

Orange county is kind far from LA but don't you think 700-1300 is kind of low compared to ATT? Did you use ATT before?
No, never with AT&T, and I am using a Hero not an Evo.
Thought you would want as much data as possible and didn't see any responses.
So disregard if this doesn't provide you some ballpark.
Its been fast enough that I never use wifi.
Downtown Los Angeles: ~1MB down, ~.4/.5MB up.

No I really appreciated your response. Thanks again. I use my phone more for data than voice. Just wanted to see whether I will lose any speed going from ATT to Sprint.
Anyway, I will have 30 days to decide so I should be good.

From La Mirada/Norwalk (5FWY/605FWY) I get 1.4MB down; .5MB up on my Hero. The EVO will be uncapped 3G as well, no? I've had ATT and T-Mobile, and my connection has always appeared to be faster. In my corporate building, amongst all the other users (ATT, T-Mo, Verizon) and phones (Eris, MyTouch, G1, N1, Pre, BB, etc), I've always had the strongest signal and fastest connection. Might just be the area though.
In westwood area, I get 300 - 400 kbps in the day.. and 1 mbps at night.. not that great

Yeah, that's very poor data speed!
I live in Alhambra, never check the speed, but it seems very fast. I can wathc spb tv, youtube and listen to the radio smoothy.
Sprint's 3g speeds are simply horrible in the entire SF bay area compared to to at&t (i know this is not the region you asked for).
I get 300Kbps - 1Mbps down (mostly 500Kbps) and 500-700Kbps up.
I checked pretty much all across the Bay Area. it is like 3g from the 90s....and might just be a deal breaker for me.
They do however have better coeverage than at&t in most places. not sure why their speed is so slow.
With at&t i get about 2-3Mbps down in most areas tested.
not sure up there but down here in FL sprint 3g is way faster than att 3g or tmo 3g.. i have the HD2 on tmo and a 3gs on att and evo ofcourse on sprint and im not sure if is the phone or the sprint network but evo kick the **** out of the hd2 and att on a test i did using the 3 phones.. evo loaded pages significantly faster than the other 2 carriers . in some sases way faster

Not true, in the last month or so I have consistently been seeing 4+ download and 500k up on my iphone 3gs. So other than uploads, Sprints 4g won't be that much faster than what I am seeing now with AT&T. In the suburbs it is dropping to 1.4+ / 400k.

[Q] 4g speeds with MetroPcs(Is it Possible)

Is it possible? Cuz I bought an Epic frm craigslist but I dont know if I should go with boost for 3g speeds or just take the chance with metro...And I live in South Florida in 4g coverage area for metro
I highly doubt it, Sprint is the only company offering WiMax 4g is the US as far as I know.
Metro pcs has lte/wimax in a few cities. If they are usng the same spectrum then your chances are good that somebody can make a work around for that. Which I go to detroit mi once a week and they have their 4g there so I would use it if someone does this?
Sent from my SPH-D700 using XDA App
Yeah but it's just to find the genius who could do it...A couple of stores are near tom me but I doubt they could...I'll just wait or search my good friend Google til something pops up
How is the Epic going to work on MetroPCS' 4g? Doesn't Metro's 4g network run on LTE 1700 / 1900mhz in the very few areas they have 4g?
Sprint's WiMax/4g runs on 2.5ghz (2500mhz), so how would the Epic pick up a Metro 4g signal?

MetroPCS does not have WiMax. They use LTE (1700/1900) for their 4g. Sprint/Clear (and partners like Comcast/Time Warner e.t.c) use WiMax.

This was the point I was making, but wasn't sure if maybe they hooked up with Sprint at some point in time recently. We don't have Metro available in Tennessee...at least not that I have seen.
Metro and sprint use 2 completely different technologies.
If they used wimax and sprint had no wimax in the area, you should be able to 4g roam, but since sprint is essentially the only major provider its kindaa hard to get on someone elses wimax network
What I wanna know is can a metro pcs lte phone roam off verizon/any form of lte on the same frequency?
EDIT: nevermind. Verizon uses 700mhz

Well, you could always double down and get a Clear account!
Thanx for the replies people...Guess I'll just go with boost & satisfy with 3g speeds

[Q] Anybody in the U.S. on 4G yet?

Does anybody got 4G service from AT&T yet? How fast is it? What city are you in?

Check the dev forum, we can now sbf just the radio from the telstra 1.4.2 which unlocks hsupa. I've averaged about 100 for ping and 2 down/1.4 up in Connecticut. Other users have reported better increases as well as some with less, it will still depend on your area. Flashing the sbf is quick and easy (took me about 10 min to dl and flash) and I haven't had any other issues. Good luck.
Edit: 1.4.2 radio is not our "4g" its just hsupa. Thanks for the correction.

That's not exactly true. The Telstra radio is only for HSUPA. I get the impression that the op is talking more about download speed, but I could be wrong.
I believe I heard somewhere that they were working on the backhaul and it would be sometime before the end of the year. I don't think I have seen anything reliable about that though, mostly just hearsay and whatnot.

you are correct, it has to come with increase backhaul at the cell sites, which has only been done in a few cities across the US. HSUPA has nothing to do with 4G. HSUPA is the upload component of HSPA, which most cell sites are on now (HSUPA is blocked on the Inspire and Atrix but not on the iPhone or Nexus One, etc). They will only be 4G or HSPA+ when increased backhaul is in place.

Yeah it's a bit of sneaky marketing (though unfortunately not uncommon).
The phone is certainly capable, however the service is not.
-Doogs™
HSPA does not equal HSPA+.
The HSUPA update unlocks 3g speed, which is HSPA.
Without the HSUPA we are basically on crippled 3g.
HSPA+, or '4g' (more like 3.5g) will come when AT&T finally gets around to deploying the enhanced backhaul to your particular city or region.

click on the coverage map, and run your mouse over the map. cities that have some backhaul in place will pop up like Chicago.
also, note their disclaimer anytime you see or read about 4G
*4G speeds delivered by HSPA+ with enhanced backhaul. Available in limited areas. Availability increasing with ongoing backhaul deployment.

AT&T's 4G network coverage map shows Baltimore as 4G enabled but I haven't seen any 4G speeds here. The fastest download speeds I have seen in Baltimore downtown area were close to 5.5Mbps. The recent radio mod does not seem to increase the download speeds.

that is better than what I get! When I was in chicago a few months ago I saw the same speeds. your download speeds are much greater than my 3G speeds at 1.5-2 Mbps here in Denver. I assume that once more backhaul is in place across the country, that 5.5 number will go up. Also, I think I read somewhere on ATT's site that 6Mbps down would be typical of their 4G deployed this year. let me see if I can find where that is stated, I could be making it up

Question:
Just how fast is AT&T 4G?
Answer:
With enhanced backhaul AT&T is seeing network speeds up to approximately 6 Mbps. Actual speeds experienced will vary and depend on several factors, including location, device, environment, and capacity. LTE is expected to deliver even faster speeds.
Note: 4G speeds require a 4G device and are delivered when HSPA+ technology is combined with enhanced backhaul. 4G speeds are available in select cities with availability increasing with ongoing backhaul deployment. For information on currently available 4G markets, see 4G Speed from AT&T and select the Coverage map.

Also I occasionally try to get a response from AT&T about this, and as of a few minutes ago they responded to me on Facebook.
Random AT&T Rep on Facebook™ said:
The HSUPA upgrade is coming soon! As for 4G we've already expanded HSPA+ to virtually 100 percent of our mobile broadband network. That combined with expanded backhaul produces 4G speeds. We expect about 2/3 of our mobile broadband traffic to be carried over expanded backhaul by the end of the year, but we don't have an ETA to share on Dallas quite yet. Thanks for your patience!

Why do you assume that? I would assume the opposite really, though I would hope it won't be noticeable. I would assume once a tower is connected it is connected and that the more towers you connect the less bandwidth there is left to share.

I assume this because once they get the enhanced backhaul in place, they can continue to "enhance" said backhaul and not let it get stagnant. of course, that may take a while. but, this is just an assumption and has no scientific backing
Wait, so this update coming out this month isn't even supposed to bring '4G' (HSPA+)? It's only supposed to bring us to full '3G', and later this year we get the full '4G'?
I'd be happy with just having 3g installed where I am!

This is a why I am so happy about the AT&T and T-Mobile merger. Regardless of it going through and no matter how long it drags on, part of it was a big roaming agreement. I am being optimistic that includes 4G because my area has T-Mobile's 21mb speed. I could handle that.

[Q] Can I get 3G+ on ATT Focus?

I've done the whole diagnosis tweaking (release 6) and pretty much all of the other tweaks I've found in these very helpful threads.
But my download and upload speeds are atrocious. 80-150 kbs mostly. I ALWAYS have a 3g signal. I'm located in Boston and before this I had a Tilt2, which data speeds avg. 2000 - 3500 kbs.
Could it be my sim card? it is like 3-4 years old. Just a thought, because really i have no idea.
I am a novice when it comes to this type of tweaking. Any help would be greatly appreciated.
Thx
The specs indicate that the Focus is only capable of HSPA (HSDPA and HSUPA), not HSPA+.
Michael.
ouch, that hurts....8(
Thanks for the quick reply...much appreciated
But your Focus should still be able to match the speed of your Tilt2 which is HSPA as well (but with HSUPA disabled). The real world experience really depends where you are and how many AT&T customers are on the same tower as you. I routinely get about 100kbps speed (download) on my various 3G smart phones as well here in nation's capital.
On the other hand, a lot of ppl who bought the new '4G' HSPA+ AT&T phones (Inspire 4G and Atrix 4G) are also rarely ever get HSPA+ speed at all. Those so called 4G phones also comes with HSUPA disabled.
So, in the end, it is the same crappy AT&T network that limits your connection speed, really doesn't matter what phone you have. I'll be happy if I can reach the full 3G speed (2 to 3 mbps down, 1mbps up) in next few years. And refuse to play the AT&T '4G' game.
You should get a new sim card considering it is 3-4 years old that will affect connectivity to 3g and hspa network..
Boston network shouldn't be a problem.
Samsung Focus At&t USA
I had the same problem when I had an old SIM card in my att fuze when trying to connect to 3g and hspa speed networks...rule of thumb is buy a new SIM when switching to a new phone....it also depends on what network your on...are you at&t?
Samsung Focus At&t USA
Yes, I am currently on Att network. Which I must say was really reliable and fast, up until the last few months...
And I will get a new sim card after work today or early tomorrow. I will let you know if that helps at all.
Thanks peeps 8)

Samsung Focus unlocked I get 3G+ in EU, if that helps. Seemed pretty fast, but I haven't done a speed test, though.
Usually I unlock my phone as soon as I get it home. With a bunch of unknowns with the Focus, I'm waiting it out right now before I do anything

I got 3G+ icoon with Rogers ROM, but not with AT&T ROM. And there's tool which can enable 3G+ icon, so I think it's just a registry issue.
3g+
I also get 3G+ with a Rogers sim card in my Focus, same card in the BB only 3G.
Is it possible to check whether this is just graphic, or there is a real difference in d/u speeds? I am using AT&T Focus in Europe.
You can check real speed with speediest.net to differentiate whether its gfx only or real network.
