HSPDA NETWORK NOT WORKING, ONLY GETTING 3G (getting hspda+ on vibrant) - Vibrant Q&A, Help & Troubleshooting

I apologize for this thread as it might not be in the correct area, but i figured most people log into the dev section so this might get answered quicker...
I have 2 questions so lets start with the first:
1) For some reason I'm not getting HSPDA network working on my phone. the best speed I've posted is about 3.2Mbs, which is not HSPDA speeds, or at least not as fast as it should be. It also says that i'm on 3G as opposed to H...is there a reason for this. Keep in mind I live in LA and they have one of the strongest networks for HSPDA (at least according to the rep I talked to).
2) Is it possible for us to get HSPDA+ speeds with a radio update. I don't know too much about the radio but it would seem to me like that is what it would take to get the HSPDA+ working as I'm assuming that it is the radio that determins your speed and not the hardware...though I could be wrong.
Just a thought, and a response would be awesome.
Thanks in advance guys and gals!

I would answer if this were posted in the correct forum.

where would you like me to post this then...not sure where to post...general q&a?
EDIT: Now posted in gernal Q&A....

settings > about phone > status
what does it say the mobile network type is? the status bar will still display '3G' if you're on HSDPA unless you're on froyo or a custom rom.

If you go to menu settings, about phone, status, it will tell you if you are connected to hsdpa... But it won't show up in the status bar...
The more ppl on the network the slower the speeds will be... I can connect to an hspa tower about 30 mins away but I don't get the speeds... my phone is actually slower now with the new tower...

it says HSDPA but it doesn't feel like that, i figgured it would just fly, but it's not as fast as I thought it should be. Also the speed test is only giving me like 3.2Mbs as opposed to my friend with with the behold II who is getting like 5...

Also, anyone got any info on the second question by chance?

i haven't done enough research on the vibrant's HSPA+ capabilities to answer

it would seem to me that the radio would do it...i mean that is what the radio is, it tells your phone what signal to use...right...can any devs help us out?

1)That is HSDPA. Normal 3G is UMTS 384kbps, HSDPA 3.5G Theoretical Maximum of 7.2 (also available in 3.5, 7.2, 14.4, etc) getting down 3.2mbps is considered very quick, connection really tops out at a max of ~5mbps, but would require you to be near a tower with a fast backhaul, and not many other people on the network at the same time. Also keep in mind speedtests are not completely accurate as they have cached data they are sending to you.
2) There is no such thing as HSDPA+, there is HSDPA in a bunch of flavors, and HSPA+. and no, our radio does not support HSPA+ 20mbps. but in field tests it was only marginally faster than HSDPA 7.2mbps anyway. the radio is a piece of hardware, there is firmware they can tweak to try and get more potential out of it, but its just more of the potential of the hardware, not extra speed.

thanks for the info, glad to know that I am at normal speeds.
Also thanks for answering on if we were able to get HSPA+ on our phones!

I believe the vibrant can get speeds up to 7.2 down. Personally, I get ~5-6mbps at my house (Seattle, WA) and the most I've hit is ~6.5.

If you flashed the Update, your not going to get a Speed increase.
After Testing & Testing me & barak both don't get over 3.5MB & with the Old Modem.bin we both get over 6MB downloads..
Another thing we noticed with the new Modem.bin is it never switches to the H network, just stays on 3G / E..
With the old Modem.bin H / 3G /E Connects

3.5 mbps is on the H network. the normal 3g network would be 0.3mbps....
However I'm not disputing that the H network could have been crippled/slower after a modem update. You are still on HDSPA, just something has been messed up about it and its only half as fast as normal for you.

I'm on hsdpa and I'm only getting .3mbps

My phone shows that I'm on UMTS and I'm getting 5mbps dl speeds. Occasionally I'll be on HSDPA but the speeds stay about the same.

UMTS is 3G, HSDPA is an improvement to the UMTS protocol.
So yes, all HSDPA/HSPA is UMTS, not all UMTS is of the HSDPA/HSPA.
UMTS (vanilla) 384 kbps
UMTS (HSDPA 1.8/3.5/7.2/14.4) 1.8/3.5/7.2/14.4mbps
UMTS (HSUPA) up to 5.76mbps Enhanced uplink portions of the data connection
UMTS (HSPA+) up to 56 Mbit/s on the downlink and 22 Mbit/s on the uplink

Theoretical Maximums, you can get UP TO that number, anywhere between 0 and that number is what reality is.

Sounds like an obvious problem, but not sure what that could be. Also, 3.5MB is not the same as 3.5Mb. 3.5MB/s = 28megabits. 3.5Mb/s = .43MB/s.

While I am mostly a fan of your answer (it is pretty much spot on), I do have to make you aware of the acronyms and their meanings.
HSDPA = High Speed Downlink Packet Access
HSUPA = High Speed Uplink Packet Access
HSPA = High Speed Packet Access (this implies that the network uses BOTH HSUPA and HSDPA)
HSDPA+, HSPA+ = Evolved HS(D)PA
Just FYI.

Best Radio in the USA

I just got the phone and I cannot find the right radio to use in order to get 3g speeds:
. What is the best radio to use in order to get 3g and HSUPA speeds over 300 kbps/sec? I use to have this speed when I got my AT&T 8525 that is ancient now. How do I get the speed I use to have off the 8525 on this phone?
Thank you for your responses in advance.

well as u see i am new at this. i read a lot from these forums since i love the htc product. but i don't know how to tether or anything like that. i just installed the radio i just displayed hoping to be able to get 3g speed. but it stays at edge at all times.

and the site u used to determine my speed i just found off google is a downlink site. and still my speed is slower than edge speeds.
Keep in mind the tower that is servicing your phone can have crap for bandwidth too.
I was near Gretna, VA on a trip and had full bars on 3g. I swear they had a dial-up modem on the other end of the tower though. Google maps were loading up slower than a typical edge connection.
In the end, it may not be your radio that's giving you trouble.

I tried it through out Atlanta today. Different towers and several areas of metro Atlanta. West Atlanta, North Atlanta, and East Atlanta.
Keep in mind my phone is the htc touch pro. I do not have the brand names from t-mobile or AT&T.
Should I try a different rom or is that a useless effort?

You may have a hardware limitation. I noticed on the various Rhodiums that were around and for sale, the unlocked Touch Pro 2's stated they were not ATT 3G compatible, although they were 3G compatible. Apparently there are different implementations of 3G.
You may want to look into whether that is something in the firmware associated with the radio (Radio ROM) or the hardware itself.
Sounds like sprint
If you have the SPRINT service or a SPRINT phone, you do not have the "3G" icon enabled. This is because SPRINT uses the EDGE network and not the 3G network. They say that their network now (REV A) is actually what they consider 3.5G and is supposed to be faster than regular 3G . I have no issues with my phone with the speed, however, if you want the 3G to display, find a custom task bar and that icon will change to the 3G. Once again, SPRINT does not display "3G"
Hope this helps.

thanks everyone for all of ur input. i'll look into all of it and get back to u. thx again.
If you have a standard Touch Pro (not Fuze or T-Mobile version), there's a very good chance you accidently picked up European version of it. European version will have European 3G, which is not compatible with US 3G frequency bands. Look into your documentation and see if you phone supports the following:
AT&T uses 850/1900
TMobile uses 1700/2100
European frequency bands are 1800/2100 if I remember correctly.
I have the Fuze and radio 1.14.25.35, and I get 396kB/s with only 2 bars...
Oh, and I'm in Connecticut.
lame!
something has got to be wrong man....i live hours away from 3G and if i even look at my phone wrong i lose reception!
BUT i got 281-392 Kbps!
Have you called your provider?

That could be true, but the documentation i have states:
Quad-band GSM/GPRS/EDGE:
Europe/Asia: 850/900/1800/1900 MHz
the 850 and 1900 Mhz should not matter if its in europe or in usa, right???
but there is a new updates. i Used IE on the phone and my speed is incredible. i was able to test 3mb and it came back with speeds higher than fast 3g. just like my old phone. but under opera it would not go any faster than 40 kbs. i used another browser called skyfire. and i went to mobilespeedtest and got: . i went to cnet brandwidth test and got 3632.3 kbps. lol. amazing it looks like opera was my problem. hear are all of my results:
opera: (after testing using the other browsers now i get these results)
mobilespeedtest.com
cnet bandwidth test
.6745 mbps
IE:
mobilespeedtest
.408 mbps
Skyfire:
mobilespeedtest.com
cnet bandwidth test
3.2588 mbps
is it me ... or does your phone get warm when u use the net for a long time???
I doubt that the results are valid with a browser like Skyfire. It does all the rendering on the skyfire server instead of on your phone. It's probably reporting the rates in between the test site and the Skyfire server. Skyfire is fast, though; it's much faster at bringing up a full webpage than any other browser. You can open up espn.com in about 5 seconds.

[Q] Flashing HSPA+ Radio?

Does anyone think or know why or why not we can flash the radio from the G2 to work on the vibrant to get the HSPA+ network connections. or is this a hardware thing? im not a dev but wouldnt mind learing so i can contribute too.
it is a hardware thing. the vibrant can get hspa connections but not hspa+. hspa maxes out at 7.2Mbits/s though, so that's still pretty good.
How would we be able to get hspa working? I think my touch pro2 was on hspa. I always had the H logo in the tool bar.
Sent from my SGH-T959 using XDA App
This same question has passed my mind as well. More often then not I notice in the phone status that the signal is UTMS, on the rare occasion is may say hsdpa. So i wouldn't be surprised if in the radio settings, utms is the preferred signal type.
we already have hspa. hspa+ is what the g2 has. hspa is just 3g...
From past experience with all of my previous smart phones the radio firmware upgrade is hardware specific.....So a Samsung radio will not work with HTC(G2) firmware.
for t-mobile, when you're on HSPA or UMTS, it just uses the 3G logo on the notification bar.
you can check at settings->about phone -> status to see what mobile network type you are on. mine says HSDPA right now, but when i'm at home, it usually says HSPA.
when they update your cell site with the HSPA+ cell, you will probably get an increase in speed because they will probably upgrade the internet connection to the cell to support HSPA+ speeds which means you get up to 7.2Mb/s. I think someone said earlier that most 3G sites only have two T1 lines as the backhaul, meaning you will probably get max 1.5Mb/s in a speed test.
Hardware thing. MIP
HSPA 7.2 is good enough for me and when HSPA+ rolls out in my area I ought to get closer to that theoretical speed more often. I've seen speeds like 5.9 Mbps on Speedtest.net when I'm near a regular HSPA tower.
I do wish we could mod the icon to display an "H" on HSPA connections like the G2 (G2 shows an "H" for regular HSPA as well as HSPA+). I remember running Klick Hero on my G1 almost a year ago, and getting the H icon from time to time on that old thing!
You can confirm you are on HSPA with the Mobile Signal Widget.
Itll show h on 2.2

The reason you cannot flash the G2 radio to get HSPA+ on the Vibrant is because the Vibrant DOES NOT HAVE A HSPA+ RADIO. Flashing the radio/modem software onto the Vibrant will not help and will probably damage your handset.
Adding software to the phone to use hardware it does not physically have is pointless.

You don't do anything to "get HSPA working", because it already works. If the cell site your handset is connected to is HSPA, then that is what your handset will connect with.
Just because the icon in the notification bar says "3G", this does not mean that you are not connected to a HS(D)PA network. Check "Settings > About phone > Status > Mobile network type" to check which type of network you are connected to. Mine currently says "HSDPA", but I have a "3G" icon in the notification bar.
Does anybody think its possible to take a baseband chip from the Epic 4g, and solder it into the Vibrant to get it to work with Sprint's WiMax network?
Only way I see that happening is of you mod the phones hardware then mod the software drivers to make it work...it can be done but is a huge pain in the butt....I use to mod our sat phones and radios over in iraq to bump signal for direct calls...the hardware side is easy little patch work needed....software side to make it work is where the work would really come in...mod for the kern...then drivers...then fixing all dependency issues for the radio...then last part is the battery issue...you would have to find a radio that wouldn't eat like it was at an all you can eat dollar dinner....but if you are into hardcore mods keep everyone posted...lol

Not without a ton of programing knowledge.
i would venture to guess no, because more than the baseband chip would probably need to be included. you'd probably some of the receivers as well. At the very least, the chip marked wimax power amplifier.. http://www.chipworks.com/samsung-epic-4g.aspx
why would you want to do that anyways? the phone isn't designed to support two baseband chips so you probably wouldn't have any way of having both tmo and wimax. might as well just buy both phones

The shipped ROM on the Vibrant does not display an "H" for HS(D)PA connections ever. It will only show "G" for GPRS, "E" for EDGE and "3G" for UMTS, HSDPA and HSPA.
Try phono which shows real time signal. I was able to find the right spot for signal at work.

http://en.wikipedia.org/wiki/Umts - when the icon shows 3G this is what it shows

HSPDA is able to provide faster speeds, but I believe it's highly dependent on how strong your signal is
Not sure myself, but if you're on Tmobile or ATT it pribably stands for HSDPA. 3G would mean WCDMA I believe.
Sent from my Vibrant using XDA App, Bionix-v 1.21
Long story short... it depends on how the ROM has been programmed to display what protocol your phone is using for data traffic.
3G just means regular UMTS 3G data
H means that it is is using HSPA, a faster protocol for UMTS 3G.
It doesn't mean that you're taking advantage of the faster speeds... that is dependent upon a slew of other factors.
Just to clear some things up. 3G is an all encompassing term, that INCLUDES the following technologies:
UMTS
HS(D/U)PA(+)
W-CDMA
EV-DO Rev 0/A/B
LTE
WiMax
As noted in the post immediately above me, the symbol it shows, depends on how the rom was customised to show each icon for the corresponding protocol.
If you don't believe me, that's cool, but go look at the ITU declinations on what is and is not 3g. There is no 4G CDMA technology. Pure CDMA is dead in the long run. All the current 3G GSM technologies, use the WCDMA or OFDMA air interface.
OFDM is not 3G

This is false. WiMax uses OFDM and LTE uses OFDMA (the same, but for multi-user as opposed to single). WiMax as 802.16e is NOT 4g. Neither is anything currently available and anything being deployed in the next 2-3 years.
I didn't say it was 4G. I said that OFDM was not 3G.
It isn't. Taking the broad view, its pretty clear to me that code div mult access is what differentiates 3G from its predecessors.
With 4G it will be orthogonal frequency
Here's a mathematical formula that pertains to all Vibrant ROMS that use an H and/or 3G
3G = H
The answer is, there is no difference except for the way they look. Both are really only using 3g.
The phone switches from hsdpa to umts back and forth all day according to how you use the internet. It automatically switches from hsdpa to umts when it is not browsing the web. That is-- if you live in an area with hsdpa. In which case it would stay on umts all day. Which would make your battery pretty happy. My battery hates hsdpa

This is false. Your phone jumps on the preferred network. Usually, unless you have specified, it sits on the fastest preferred network available. As such, battery consumption improves when you disable 3g (which is HSPA AND UMTS).

I didn't say it was 4G. I said that OFDM was not 3G.
It isn't. Taking the broad view, its pretty clear to me that code div mult access is what differentiates 3G from its predecessors.
With 4G it will be orthogonal frequency

If it's not 3g then what is it? OFDM is used on both current 3g and future 4g (LTE-Advanced) systems.

hi there,
I believe what you say and if it is just a matter in which the ROM is programmed, why does my stupid S3 still switches from H+ to 3g?
I dont know and I cant tell if either of the two is faster than the other, but it is annyoing the constant switching
Thanks

H+ = HSPA+ = 3g. There are different names for the different 3g evolutions and technologies, but they are still 3g. It keeps hopping between the networks because you're unfortunately in an area with bad coverage for the faster network.

[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] Disable HSPA? Leaving HSDPA only?

Hi, I looked for this in all motorola forums but I couldn't find any real solution.
It seems the latest update to my home network (HSDPA to HSPA) is not well received by my phone. My battery is draining really fast since this upgrade.
Is there a way to enable ONLY HSDPA? I mean, HSPA is great for downloading and uploading, but battery life is really poor. I had very good battery life with HSDPA and I'd like to set my phone to this type of data connection.
Somebody told me to look for some entries in build.prop but I didn't find anything. Does someone know how to do it? Thanks

Hey, thanks for your help. Well, I'm not suffering battery draining for any other reason. I don't want to use 2G networks only. Just want to change HSPA to HSDPA. That way, I'll go back to having the usual battery consumption.
Any other suggestion?
HSPA is a term that encompasses High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) - if your network was using HSDPA, it was an HSPA network.
Enhanced HSPA (HSPA+) is an enhancement to HSPA that enables download speeds of up to 21Mbps and beyond, up from the typical 7.2Mbps. The Atrix is a 14.4Mbps compatible HSPA+ device.
So you saying you don't want HSPA, but want HSDPA doesn't make any sense. Do you want to disable the increased upload speeds? (HSUPA) or the HSPA+ speed enhancements? (up to 14.4Mbps) I know Samsung have an option to disable certain parts of the network through a hidden network, no idea about the Atrix though.

Yes, I want to disable HSUPA (what makes it HSPA) since it's killing my battery. I found a lot of info on Samsung phones but I don't know how to do it in a Motorola mobile
Sorry to bother again. Any solution yet to prevent phone from going on HSPA and stay in HSDPA? Thanks in advance
Just for your information, I found some build.prop tweaks to set HSDPA only, but none of them worked. Any ideas? Am I doing something wrong?
Thanks

BUMP... Still trying to set phone to HSDPA only... Any thoughts?
it can be done, it took me three weeks to figure this out. we had a flood come through here about three weeks ago and it did something to just one antenna on the tower, i dont know what it did but it prevented anybody using a phone on hsupa from using their internet on their phone, i called att multiple times on the issue with no fixing of the tower that was transmitting a bad hsupa signal, the same antenna was transmitting a good "3g" signal or "hsdpa" both of my 4g phones would work anywhere else in the world except for at my house where the bad hsupa signal was. so i knew i had to find a way to downgrade to hsdpa to get my phones operational again, no help from att as to when or even if they would fix the towers. att thought i was crazy because i was the only one complaining about it because everyone on 3g was unaffected, probably only a handful of houses on this one antenna, att locks you out of your phone from being able to go to 3g or 2g, all automatic. 3 weeks of this crap then one day i remembered when the atrix first came out hsupa was locked out, remember all the scoff att got for that one, so here's what i did to shut off hsupa and get my phone back running again:
1. make sure your bootloader is unlocked - not sure if this will brick your phone if it isn't
2. download these radio packages http://www.megaupload.com/?d=V0LDOGFJ
3. flash the one radio that says att shipping radio or something like that through rsd lite (this is the original radio that shipped with the atrix) and don't worry its safe to flash if you are on gingerbread..
4. reboot your phone and you will be locked into 3g or hsdpa thus locking out hsupa
5. if you want to turn hsupa back on just flash the other file
this method worked great for me and got my phone working great again and no hsupa for me anymore until att gets the tower fixed which may be never since i'm probably the only one on this particular antenna with a hsupa phone.
all we need now is a nifty dev that can hack one of these radios to shut off automatic network selection for those of us that are stuck on it.

Well, thanks a lot. I was able to set phone to HSDPA only by flashing the radio you provided. I can't test if it really decreases battery drain but I'm going to try tomorrow with regular use. Thanks a lot!

I can see why he called it hspa since this is the information displayed by the phone vs when the phone is on hsdpa. or what I call 3.5 g

Hey pal, your method worked! After flashing the old radio, the phone is on HSDPA only and battery life is way better, back to Froyo times. I don't really care about the enhanced upload. Download speeds are as good as they were on HSPA.
Thanks a lot.
Can you please upload those radio again? I'm suffering the same thing with my atrix. Thank you.
