HSDPA+ Speeds

yahoowizard · Oct 31, 2011

About how fast are we really looking at for our phones as of now? AT&T claims up to 21 mbps, but each speed test has its own results, and just looking for what I'm supposed to be realistically seeing. Also want to check to see how much different it might be from LTE, but yeah, probably not going for the upgrade (my phone just shipped in today, and it wasn't entirely fun to see the news story this morning x.x)

I see anywhere from .5 to 3.5mbps down and .5-1.5mbps up using speedtest.

i average 3 mbps down, 1 up in DFW. which was better than my iphone 3GS, which was about 700k down, 200k up.

oddly though, i ran a speed test against an iphone 4 (not S) side by side with my S2 and i got 3mbps down, 1 up, and the iphone got 5 mbps down, 2 up.

ran it multiple times, iphone always had higher speeds.

I'm in a north suburb of Dallas (so I should have LTE), was playing with my Galaxy S2 and an iphone 4 yesterday as I ran errands.

Which was faster flip-flopped wherever I was, sometimes the Galaxy was significantly faster, sometimes the iPhone was (odd to me, as I ran speedtest from both devices at the same time in the same place).

I've had a range of .264 to 10.9 on the Galaxy, .20 to 8.8 on the iphone 4 (not 4s)

ditto. Depends on where I am. at home I'll get 3-3.5 and at work i'll get .1-.5 down. I dont use the speedtest app because I find it inaccurate at times. I use the speakeasy speed test through the browser.

shouldn't matter that you have LTE in your area because the phone isn't an LTE device.

In NY (city, outer boroughs, upstate and long island), I averaged .35 to 4mb down, mostly in .8-1.5mb range though.

I mean, my old phone was a Samsung Captivate, which ran on 3G, and this is supposedly "4G", thought there would be some speed increase but seems to be the same x.x

if you believe AT&T, LTE will get you an average of about 25 mbps (real world). so it should be 3-5 times faster than the S2's HSPA+ data speeds.

there's no debating, LTE data will be significantly faster.

Well, they claim HSPA+ to be 21 MBPS, so not sure where they're going that. On the same note, I'm getting about 8 MBPS on my phone, so not sure what's up with that either...

HSPA+ claim versus HSPA+ real world is different. which is why said, i've heard reports of AT&T's LTE networking running around 25 mbps real world

yahoowizard · Nov 1, 2011

Well, this is AT&T's first LTE phone, so...but yeah, I've seen really high speeds from other LTE networks, such as 25 mbps and stuff..

BigCiX · Nov 2, 2011

I've gotten as high as 7mbps early in the morning. During the peak hours it ranges from .5-3mbps.

chienb · Nov 3, 2011

socal 92626 getting max 2.5 down 1.5 up.

so sad...

understood...I mentioned that more as "hey, I have the premiere network in my area, so my reception on whatever band should be good"

21 MBPS is the theoretical max speed. You'll never see it. Conditions would have to be 100% perfect: you'd need to be off a tower running HSPA+ 21 mbps with no other load besides you, you'd have to have a clear line of sight to the tower, the phone would have to be in perfect condition, the wind would have to be blowing the proper direction, etc.

Real world is always very different from theoretical. Even being inside with one wall between you and the tower could affect the signal.

Oh, I misunderstood that someone said AT&T had claimed it's LTE network had 25 MPBS speed, and I pointed out it wasn't that different compared to the expectations for the HSPA+ network...But yeah, he was talking about real speeds, not theoretical...

Actually SGS2 has 21mbps baseband chipset, BUT AT&T's HSPA+ network only runs up to 14.4mbps because they still use 16QAM modulation. You will never see over 14.4mpbs until they start using 64QAM modulation that is essential factor for getting speeds over 14.4mbps.
Here are the videos:
AT&T HSPA+ uses only 16QAM - YouTube
