HSPA+ etc - G1 Q&A, Help & Troubleshooting

So with t-mobile's recent upgrade to HSPA+ this is bothering me more than ever. Am I the only one that has to run multiple speed tests to get it to switch to the faster network? I clearly have the signal to get the faster speeds, but I have to run a single speed test first to get it to "switch", and then on the next speed test I get the faster speeds. Is this normal?
Secondly, what's everyone's latency? I always have MUCH higher latency than any of the other speed tests I've seen. I average about 150 on the upgraded network, and about 300 on the other one.
If anyone is in Seattle, what kind of latency do you get on speed tests (tethered or not)?

Q: about 3g on kaiser

How well does the hsdpa work as far as latency and speed. I know its therotically possible to play xbox live off a cell phone connection as ive done it on my Wizard. Could someone run a speed test from the phone and maybe a few pings.
Appx. 800/1.2...should be theoretical speeds of up to 3.6, but I guess AT&T in this area hasn't uncapped the towers...
800 down or ping? thanks in advance!

Problem with HSDPA

Ive noticed that the H symbol doesnt actually show hsdap availability. For example, when I have 3g signal but there is no data transfering I have a 3g symbol with arrow next to it, as soon as i start transfering data it changes to an H even if im connected to a 3g cell with no hsdpa functionality, (confirmed by a speed test).
Any ideas how to actually show whether i am in HDSPA coverage or not?

Why do you say that your not in a HSDPA area or signal range? Just because your not getting really fast speeds? Most HSDPA speeds are from 300Kbs-1.5Mbs when that little 3G changes to H your are most deffen... getting HSDPA
well ive done speed tests when it says the H and it varies between 200 and 300 sometimes.
Is that normal?
Yes just because the Max Download speed is 3.6Mb that does not mean you will come any place close to that. there are so many factors that will throw the download speeds off hell the wind blowing from the west and not east the window being closed and not open you get the Idea
I've been confused by this as well and while speed is clearly better with the "H" on than with 3G, I never go above 450kbps which is a bit slow, 3G tops out at 340kbpw. I wonder how efficient the Qualcomm chip is for 3G+, I hear that Samsung i600 users are getting speeds of 600/700 in the same area.

3G Same Speed as HSDPA?

Hi, i'm on t-mobile UK. I've run some internet speed tests and i'm getting about 300kbps on both 3G and HSDPA. Is that normal - i thought 'H' was meant to be quicker?

Not nornal because HSDPA (If configured and rolled out properly by the operator) gives up to 7.2 mbps
Might also depend on your contract. The more expensive your data contract, the higher the speed you get.
out of interest which speed test did you use?
check with t-mobile on your contract. in general, W7W £7.50 users do not get HSDPA included. You'll see the H symbol, but you wont get the speeds.
Also, depends on network traffic in your area, network capacity etc. etc.
I'm on the £12.50 W7W add on and get around 600kbps. not the full 7.2mbps, but that is a theoretical maximum, and you will never get that. same as ADSL is 'up to 8meg' , HSDPA is 'up to' 7.2meg.

3G vs Edge

Is your 3G much faster then Edge, I just ran 2 tests firstly deleted cache, cookies and history then went to http://www.nationalgeographic.com in Opera.
On Edge it took 58 seconds to load the page then on 3G after clearing cache, cookie and history it took 45 seconds. I then tried http://www.cnn.com on Edge it took 56 seconds and on 3G it took 46 seconds.
There doesn't seem to be much difference for me between the two and I could probably make do with using Edge which while slightly slower is still fast enough, is my 3G particularly slow or is my Edge particularly fast? Is there really that much between the two.
The answer will depend on your network. In theory, on an ideal network,located close to a cell base tower, 3G should be many times faster than Edge, which is just a small improvement (double the speed?) over GPRS.
In the real world, or at least my real world in the UK on T-mobile, 3G is rapidly becoming a bit of a joke. What they don't tell you, is as the service becomes ever more popular, everyones speed drops. Also, as you move further away from the cellular tower, your speed drops again. And, using a small phone with an inefficient antenna, your speed drops yet again.
What starts out on paper as an advertised 7.2 Mbps 3G service ends up as 100 - 200 Kbps under normal conditions as described above. You will never, ever, see anywhere near the advertised figure. Nobody will.
You might well find, depending on your location, and whether your mobile provider has completely geographically separate 2G and 3G masts (as most do in the UK), 2G (or 2.5G as I believe Edge is known as) might be almost as fast as 3G if the mast is much closer and it has fewer users, despite being far slower in theory.
I have not done any tests. But, one of the reasons why I didn't want to get the D2 was because of no 3G here in the U.S. But, after using it with Edge I am pretty satisfied with the speed and streaming Cingular video.
I notice a pritty big difference between HSDPA and Edge, I can stream live football video on HSDPA, and when I try edge, it only just about streams radio.
There's more to the apparent speed of loading web pages than the raw download speed. For a page that contains lots of small images you may well find that the connection with the smaller latency is faster rather than the one with the fastest data rate.
I did a speed test at http://test.dslreports.com/mspeed and got these results
1st Run 88 kbit/s EDGE
2nd Run 51 kbit/s EDGE
3rd Run 95 kbit/s EDGE
then switched to 3G and got
1st Run 181 kbit/s 3G
2nd Run 106 kbit/s 3G
3rd Run 109 kbit/s 3G
4th Run 66 kbit/s 3G
5th Run 93 kbit/s 3G
6th Run 82 kbit/s 3G
So while the first 3 runs were faster then the EDGE results and last 3 runs were in EDGE territory, and the max I got was 181 kbit/s far slower then even the 1.8 mbit/s quoted for 3G, it seems for me anyway 3G isn't *that* much faster then EDGE.

[Q] Very slow 3G data speed

I have problem with my captivate such that 3G data speed(according to Speedtest.net app) does not go over 300-400 kbps. Also app chooses closest server as Wichita Kansas and I am in in Portland Oregon.
Besides the speedtest app Internet browsing is slow in general even though signal is good ,3-4 bars constantly.
About 1/2 mile away from my work place ATT has put new 7.2Mbps tower but even in close proximity of the tower my download speed does not go over .5 Mbps.
I got new SIM card at ATT store but that did not help either.
BTW phone is rooted
Any suggestion would be appreciated
The tower is 7.2 megabits. Your theoritical speed limit is about 1000 kbps so...did you try intalling the hsupa modem? Be warned that it will screw up bt and headset controls
Using the power of the force close
Have you tried the speed test multiple times? I verified my tethering with really high speeds which were cut dramatically the next morning. It could be time of day or just lousy network congestion. Try again over wifi and compare to your computer for a benchmark.

On wifi there's no problems at all. But seriously regardless of the time of the day or location I do not get anything better than average EDGE speed even the phone shows 3g icon constantly. Is there some APN setting that I need to check.
I compared the download speed to iphone4 , 3gs, HTC ARIA and motorola q9h on the same time of the day and on same location and captivate gets at most 1/3 of download speed of the other 4 phones. (Other 4 phones get in average 1.2 Mbps download)
Not to mention that even that speed is actually low for HSDPA. I did not flash HSUPA since I'm not so concerned with upload speeds
