[Q] What defines or limits the HSDPA setting? - Galaxy S II Q&A, Help & Troubleshooting

Hello.
I'm curious about the value of HSDPA as shown in my phone's status (I'm running Resurrection Remix JB v3.0.6).
No matter what I do, it always shows as HSDPA:8.
I set it on Build.Prop as:
ro.ril.hsdpa.category=14
which is what the GSII is supposed to support.
a. Network Info II claims my wifi link speed is 5 Mbps (just below the :8 limit of 7.2 Mbps).
b. My wi-fi speed, as per Speed Test, is close to 14 Mbps (my laptop gets around 17 Mbps) and that's what I'd expect.
So where does the :8 come from?
Is it the state at rest and changes as I download? Shouldn't it show the maximum supported category?
How can I see what its value is during download?
Thanks in advance.

u can check with play store for some third party apps that do speed test for u

I'm not sure I understood the question, but you can test your connection speed w/ this app https://play.google.com/store/apps/...DMsIm9yZy56d2Fub28uYW5kcm9pZC5zcGVlZHRlc3QiXQ..

Sorry for the mixup.
I know my connection speed as far as downloads are concerned.
I use 'Speed Test' as I mentioned and it clocks at around 14 Mbps.
My question is about the meaning of: HSDPA:8
As far as I can tell, it defines a network limit of 7.2 Mbps.
So how come I get 14 Mbps?
The only thing that crosses my mind is that maybe HSDPA refers to network speed limit, IF I download through the phone provider.
Maybe it doesn't apply to wifi connections?

I think it refers to the mobile network, I never heard of limiting the wifi connection through a setting xD sorry for my bad English!

REV A not working for me

what do you enable to get the revA speeds?
I am on the 3.2.3 rom and the .3 radio.
I just ran "mobilespeedtest" and ger 349 to 645.3 kps.
What am I doing wrong?
I have already.
.. select data network (#777).. click edit.. click next.. click next again..

without any sucess.
I am sure there is a simple setting I forgot about.

It is on by default with the latest Radio ROMs if it is available in your area. Anything above 256K/sec I believe is REV A speeds. I get any where from 150K to 1meg depending on the signal strength.
you people need to clarify Kbps/KBps/Mbps/MBps.
Big difference between bits and bytes...I've been getting 600kbps or 84KBps (plently fast for surfing) with crappy signal strength. I'll have to do some more testing with it.

I use http://www.dslreports.com/mspeed so what ever units they are using is my units that I quoted above.
EDIT: with a 30% signal strength on EVDO I get 194 kbit/sec but have gotten upwards to 1 mbit/sec with full strength.

That is not correct, as non RevA has speed bursts that is capable of getting up there.
I'm running the stock VZW rom and with full EVDO signal (non RevA) I've gotten speeds in excess of 600kbps

Anyone else test on this site with both PIE and Opera?
PIE gives me a consistent sub 100kbits while opera gives me over 300kbits every time...
When tethered to my laptop.. 1000kbits +
its all about how efficient the browser you use is.
1xrtt, 1xEVDO, 1xEVDO-REV-A Lesson ,,,, again
Ok here it is,
I Do this for a living so here it is for real : 1xRTT shares voice resources, download speed max is 153.6kbps, up is 56k. 1xEVDO is an overlay with dedicated radio channels and up to 4 T1 spans connected directly to the front of the DOM (Data Only Module) with max theoretical download speed of 2.4mbps and max upload of 153.6kbps, this due to the reverse being similar to standard CDMA. REV-A is same sort of DOM but now called a DOM-A and has a max theoretical download speed of 3.5mbps and upload of 1.8mbps because the reverse link is true EVDO. If there is only 1 T1 on the DOM you will not exceed 1.54, actually 1.2 because of overhead bits, and remember also about EVDO that speeds drop more sharply with signal loss than 1xRTT does. There is no REV-A active indicator on the 6800, but it is now on by default, so if it is there you will have it.
Anyone got an upstream test I can run to test for RevA speeds? My download speeds have not changed since I upgraded.

Thanks MadMan for the info. Very helpful indeed. I assume bits not bytes in the speed units?

Ok, I just did a speed test using DCD's 3.2.5 ROM with radio 3.24.50 ROM.
===
http://www.speakeasy.net/speedtest/
Download Speed: 1861 kbps (232.6 KB/sec transfer rate)
Upload Speed: 588 kbps (73.5 KB/sec transfer rate)
===
SETUP:
I hooked up my phone via USB, went to Comm Manager, turned on internet sharing, clicked "Connect" on the screen. then I disabled all my other network adapters, and unplugged any internet cables. I disabled the WiFi and the Internal NIC, and unplugged the cat5 from the NIC. Also, I got my IP from 'whatismyip.org' and ran a WhoIS, and it was a Verizon IP. So this is the most clean/variable free test you can get. I had full bars too, but I do not know how far I am from the nerest tower. Just thought I would share that.

I would have liked to see you run the speed test on the device with at least PIE in the same location at about the same time to see the difference.
It certianly seems to me that while the phone can achieve fast speeds, the software and amount of free resources based on other applications running will have a major impact on the speeds you see. As I Posted earlier the speed in IE, Opera, and while tethered were dramatically different.. all performed within 5 minutes of each other in the same place.
Just because you dont see major speed on the speed tests does not mean Rev A isn't working.
I didn't have to do anything for my Rev. A to work. I am tethered to my laptop and get amazingly fast speeds with only 1 bar of signal strength. I am in Des Moines, IA and love my Sprint PCS!

im getting 1600 kb/s download speed with wmwifirouter and 1000 kb/s with pdanet. havent tried ICS.
I'm in fort worth tx and my speeds fluctuate from 50 to about 350kbs. The prl is 60613 and the rom is 3.56, radio is 3.42.02 and pri is 2.04-003. The last month or 2 the data speeds have been slow as molasses. That's tethering with pdnet and pie on the phone. Could somebody throw me a bone on this. Thanks.

Absurdly slow on 3G signals??

Does anyone else on Tmo/Orange Uk have issues with 3G speeds? Mine are much slower than on the SGS and I can't figure out why.... I'm starting to worry if my phone has a fault ....
anyone had issues?
thanks!!
Dont think it's your phones fault. I get up to 4mbps everytime i take a test, and i got only 2mbps with my desire so, yeh this phone rocks.

just 3G speeds? or with 'H' aswell? download 'speedtest' from android market(free), if your download speed hovers around 356-357kbs, then I would say your download speed is capped.I'm with t-mobile, and mine was. I had to phone and get through to their techy dept and get them to enable 'Hspda'

whats the difference between H and 3g? coz mine goes from h to 3g and then back to h, that didnt happen on my desire. i always thought H was the same as 3g :S

http://blog.ruggedandmobile.com/2010/01/26/a-guide-on-the-difference-between-gprs-edge-3g-and-hsdpa/
G - this stands for GPRS, and is the slowest data transfer method (approx 32 - 48 Kbps)
3G - This is the next level available on T-Mobile, and is around 10 times faster (384 Kbps)
H - stands for High Speed Downlink Packet Access, and is essentially 3.5G. In theory, TM's network
can transfer at 7.2Mbps, but real world tests tend to average out at around 2 Mbps, still significantly
faster than 3G
There is also HSDPA+(H+) which is even faster.
Hope this helps explain

[Q] Speed Test - Data Speed Test Results... Weird?...

Hi All,
I have the Speedtest.net app on my SGSII and have run some speed tests and am getting some results that I find weird.
Yesterday I tested my network speed from my home (small basement suite apartment if that matters) and the results were as follows...
Network HSPA Download -0kbps, Upload -0kbps, Ping -1ms at 8:12PM
Network HSPA Download 247kbps, Upload 15kbps, Ping 1172ms at 8:14PM
Network WiFi Download 11401kbps, Upload 505kbps, Ping 47ms at 8:26PM
Today
Network UMTS Download 2269kbps, Upload 664kbps, Ping 185ms at 10:07am
I know the WiFi ones will be different but can anyone tell me why my HSPA ones from yesterday are SO LOW and if my UMTS (3G) one from today is atleast in the normal range?
I am confused...
Thanks,
One test isn't enough. Maybe the network/cell tower was saturated or had a problem, preventing full speed in your HSPA test.
The 0/0/-1 are Speedtest's bug.

Thank You for the info. Can you explain to me... Is UMTS 3G and HSPA is 3G+? Is that correct?
Today at work I ran a couple more tests and my UMTS Results were fluctuating as well... (I diddnt have any tests that came back HSPA today so far) Anywhere between 863kbps download to 1390kbps download and 301kbps upload to 748kbps upload... Are these weird as well? How can I get a true test of my 3G and HSPA speeds?
they are just slower speeds, the network seems to be under heavy capacity in your area. the only way to get a better idea is to test in the middle of the night, at 1 am, when the network is nearly empty and wide open.

Thank You as well for your response. Can you tell me... IF my device was folr some reason running in 2G or "Edge" mode it would show that as the "Network Type" in the test like it says UMTS or HSPA? Is that correct?
Yes if your phone switches to edge you will see an E at the top of the screen and the setting menu will say edge. You were definitely on HSDPA though, just a slow network, cause edge is limited to 236 kbps. Your speeds were higher than that except for the one that goofed completely.

[Q] What are normal ping, down and up speeds?

I just got around to downloading the speed test app to see how fast me x2 is and after the first test here is what I got:
Ping:19ms
Down:4989kbps
Up:703kbps
Now I dont know much but something tells me that up speed is a little low.
Im on cm7 with the Mash up script and wifi on.
Will the numbers be different if Im on 3G? Are these numbers even remotely good?
Many thanks to all!!
Apps aren't always accurate. I'm not sure what you meant will it be different if I'm on 3G? Wifi and 3G will always differ, wifi is much faster depending on your provider, where 3g can lag at times
On 3g I usually hit 3d and 1 up
Where wifi I'm like 25 down 8 up out there about.
SMILE It's Not Illegal Yet
Your ping time and up/down speeds can vary even when connected to the same tower or wifi network depending the congestion at any given time on the bandwidth provider's network, among other factors.
Your seemingly low upload speed could be attributed to other devices on the wifi network using the upload bandwidth allotted by the isp at the time you performed the speed test. It may also be the case the connection supplying the wifi network is 6Mbps down/1Mbps up. Your upload and download speeds while on wifi can only be as good as the connection from the isp regardless of the settings on your device or how many other devices are on the network.
For what it's worth, I have a Verizon 3G Network Extender plugged into my wireless router, meaning that both my WiFi and the Network Extender can only supply a connection that at best is only as fast as my cable modem's connection to Comcast. Eliminating all conflicting variables (e.g. no other devices on the network when running tests), my Droid X2's 3G upload and download speeds are consistently slower than when I'm on wifi.
19ms is a pretty good ping time, btw.
Lots of useful info. Thanks guys!

I have also been curious and suspicious of my 3g data speeds. When I was stock and rooted with 2.3.4 I would get on average 20-30 kilobytes/sec in my house with a poorer signnal of -87dbm this is using speed test and checking the down up speeds with the mobile network app that puts the speeds up on the notification bar. I used that to monitor downloads and web browsing speeds which agreed well with speed test. In a good coverage area -67dbm I achieved pretty consistently 130-230 kilobytes/sec. I am now running eclipse 2.0.4 with CMDA build.prop edit to increase 3g speeds. I ve only noticed a doubling of speed when in -87dbma area nut otherwise I cannot achieve anyhigher than 300 kilobytes/sec. I wonder could my radio be weak or bad? I thought 3g speeds would but up to ~500 or greater in really good coverage areas.

I never considered radio quality when I looked at my speeds. Exactly how one would go about checking ones radio quality is far beyond me. Its definitely something worth exploring (in my opinion)
Right I would also need to test other 3g speeds on a different phone on the same networko in the same area to rule out network end probs. Plus I got my DROID x2 used so that might be it there. Also if the radio heats up from persistent use that might reduce efficiency and lower speeds.
Those are fairly decent speeds. For a mobile device, that's about what I would expect. Your ping, 19ms, means that it takes .019 second to reach from your device to the Verizon servers, then to the servers of the sites you are accessing, and then finally back to your phone. Anything less than 80ms is considered good, so you have an excellent ping.
And to clarify, your upload speed will never be as high as your download speed. It's a throttling mechanism used by all (and I do mean all) internet providers of any kind to prevent things like hogging their bandwidth with torrents and the like. It's essentially an industry standard.

What are your WiFi speeds with your Note 7?

No matter what i do I can only get 65Mbits (10Meg) per second (and thats on 5Ghz) Is this the max speed the phone can handle? I have 150Mbit per second internet connection.
Im good here...

How did you attach your screenshot, I'm trying to add mine and can't find an option to add an attachment.
NEed to be a bit more specific....
Airplane mode on, then wifi on, speed test, should usually get you 80mbps or higher..
The real test is doing a SMB or internal network transfer... can only get 5-8MB if I am lucky...
First phone was 500k for internal SMB. Speed test always shows great speed going out, but never on a local network..
My speed is super ok WiFi up 380 / down 411 Mbps
I get the advertisex ISP speed (120mpbs) using the speedtest app.
SMB I just about get 1 MB/s
Are you getting 8 MBytes/s ie 64 mbps? I would be very happy that. I warch videos by running the straight of a network drive, the get choppy.
