Just thought I should bring this up. I have noticed that most of the builds does not support HSDPA which is a faster version of UMTS data networks, (check Wikipedia for more information).
I have first noticed it after flashing KingxKxRom, which is the only Rom - that I have tested - that supports HSDPA. Maxisma, Ccyrowski, Cyanogen, and Enomther Builds do not support it for some reason!!!
Correct me if I’m wrong; Hero, Magic, and the Dream do support it by hardware. So I wonder; where the Ball was dropped , or is it just that Kingklick is using a different base for his build, or is it a kernel matter.
This was bothering me for several days and after a lot of research I could not find the reason behind it. I’m not a Rom developer by all means; just thought developers could shed some light about it.
This has been discussed previously. HSDPA is actually supported in those ROMs, however the "3G" icon doesn't change when you are connected on a network with HSDPA coverage. I guess this is because HSDPA is just another type of 3G, so its not necessary, its just an indicator of a faster "3G" connection also known as "3.5G".
Hope this helps.
edit: if you get download speeds higher than 384kbps then you are connected on a network with HSDPA support, you can actually test it using a speedtest.net app on the market.
The issue is not the icon, withier you review the settings>about or use *#*#info#*#* command it clearly state what type of network you are connected to. I have also tested the speed and it does vary.
I have no idea how any ROMs would not 'support' HSDPA, as it would depend on what hardware you're using and your carrier's network.
If it makes you feel better CyanogenMod most definitely does as I'm using it right now and I'm on a UMTS network. I think you're confusing the network type with the protocols used to get you your data.
I am using CyanogenMod's latest rom and im getting some great speeds on the web 3mb- 5mb download speeds!
As I understand HSPDA is an upgrade to UMTS, if your hardware and network supports HSPDA you will be connected to it, otherwise you will use UMTS only. That’s why I think it has to do with the kernel used rather than the build itself. It did actually show that HSDPA is used in Kingxkx Rom.
and I did try CyanogenMod's but it does not switch to HSPDA.

what phone are you using; im using the Dream.
If you see the H symbol then you are getting 3g also some states dont get 3g yet or have some crappy service.
I can tell you for sure that they all support HSPA. My Touch Pro 2 has a "H" icon and clearly states HSPA (aka HSDPA/HSUPA) network. Right next to it is my G1... which says connected to UMTS w/ the 3G icon. Both test at around 700-1100 kbps download and 200-500kbps upload. Those are clearly HSPA speeds and not UMTS which tops around 400kbps download.
I have used a few ROMs that have the H icon and it makes no difference in speed. It's just for looks.

Some people prefer the 3g icon thouch i think the H looks better on hero roms
Maybe I took the wrong approach in discussing this, although the main use of HSPDA is Data, Telephony could use the protocols as well. I did a small test of not connecting to Data, by deleting the APN for it, or by un-checking the “connect to network” option. It still shows the phone is connected to HSPDA vs UMTS or GSM network!! That is in Kings Rom vs. Other Rom’s. Any Ideas?

Well I'd better sue Vodafone then for selling me a phone that supports HSDPA when it doesn't!
On a more serious note, HSPA is a packet access protocol used over a UMTS network for data, not a network type. Just because you're getting the '3G' icon doesn't mean you're not getting HSPA throughput.

Thanks for your effort so far. Forget the icons "3G" or "H" that’s not my issue. Without connecting to data either; why when I use kings Rom in the setting/about section it shows network type as HSPDA, but when I use any other Rom it shows UMTS. Giving that I didn’t move and in the same place.

Ahh, now I get you. That is interesting though. I've only ever got UMTS as my network type but I definitely get HSPA rates so I took it as a given. Was there any correlation between using a certain type of ROM (like Hero vs. AOSP) where the difference appeared? . I remember trying a Hero ROM once and getting the 'H' icon instead of '3G' so maybe it's specific to those. Wish I'd checked Phone Status now...
It's possible kingklick made some form of modification to get the point across in his ROM, or possibly different APN settings he specifically uses. Kind of doubt it though.

I agree I think it’s something that King did, or it relates to Rom’s based off a phone other than dream, I just flashed back a rooted stock 1.6 ADP DRC83 and it showed me UMTS, so it’s not the fault of the Rom developers I guess. I will try to test this further and I wish if king or other developers could further explain it.
Edit: found no correlation to what the Rom is based off; tried a magic, a hero, a dream based Rom’s and they all show UMTS, only Kings Rom show HSPDA, I will try to PM him tomorrow and find out if it’s only a naming thing or if he did something else.
I've had several diff roms show hsxpa in the status screen, it just matches the icon (eg replace the build.prop to get h versus 3g icons and you'll see the network type change in status too)
All the first hero builds did it as well as all Haykuro's orig Magic to Dream port
Also a stock Rogers Dream shows HSDPA. Here in the US they dumb things down for us by just calling it 3G or if you're real technical UMTS. However in Europe, Canada, and most of the rest of the developed world it is called what it truly is, HSDPA. When you see UMTS in there that is because it is a broader category. The same way EDGE is just an extension on 2G GSM (EDGE is 2.5G), HSDPA is an extension on the original UMTS 3G system (HSUPA & HSDPA are 3.5G)

Plain and simple it does not matter what the phone shows 3g or H if you are in an area with the HSDPA you will have the higher speed data. All HTC androids at least, do have the hardware for it. As far as voice over HSDPA that is not currently enabled yet until the HSDPA is fully up and functional. If you are not getting High speed 3g then you are most likely in an area that does not support it or the connections are maxed out and you are defaulting to the standard 3g network.

i would like to see a different logo, ex "3G' or "H" when i connect to tmobiles new HSDPA+ which has much faster speeds...is this possible?

very, someone just has to program it
The difference is the Radio Interface Library. As far as I know the htc source libraries distinguish HSDPA.
http://www.netmite.com/android/mydroid/development/pdk/docs/telephony.html
system/lib:
libhtc_ril.so
libreference-ril.so
libril.so
You could try pushing HTC sourced RIL libraries to these other builds but the source code isn't available as far as I know.
My fastest tests I took with Infuse were on UMTS network, ranging between 6000 and 6500 kbps. I beleive it's a 3G, right?
Immediately following it from 1000 kbps to 6000 kbps were HSDPA tests (I assume those are "4g"?)
I took about 30+ test in different times, different networks. But top 9 speeds by download were on UMTS network following by HSDPA network.
What gives? If this is a current state of affairs, then I'd rather just lock to 3G and save battery.

Lo should have been forced to hpsa+ when you enter data no matter what. All the tests were on 3g just some happened to be faster. By the way our 4g is not 4g only lte is. Its a gimmick lol. And one thing suprising is regular 3g and this Plus stuff is the same stuff just having more bandwith for it to go faster.Uses no more battery.

No, this is consistent. There are way too many tests to consider this an accident. See results below. Umts is faster then HSDPA on 30+ tests I run so far. As you see in locations they are all different, also different parts of the day as well. Sample is too big to consider this an accendal observation.

Okay, some clarifications. I'm guessing you're just talking about how it was displayed in your app, but HSPA and HSPA+ are both UMTS based networks, so 3G and HSPA+ "4G" are both UMTS. The difference in this current implementation of 3G and "4G" is that 3G is HSPA which maxes out at 14 Mbps downstream, whereas "4G" HSPA+ maxes out at 84 Mbps downstream. It's the same technology, just basically a software update.
Now, most HSPA 3G phones don't support 14 Mbps downstream. I think most max out at 7.2 Mbps. Most HSPA+ 4G phones max out at 21 Mbps, or some even support 42 Mbps, however, being that AT&T's network is 16QAM, their network's max speed is 14 Mbps. So really, HSPA 3G is entirely capable of going as fast as HSPA+ 4G on AT&T's current network, assuming you have a phone with a fast enough chip in it.
As for the results you posted, I'm not really sure what to say. You said your UMTS tests gave you 6000-6500 Kbps, but then HSDPA tests gave you 1000-6000 Kbps. What's confusing is that whatever app you are using is posting random labels on the network which are all technically correct, but only confusing people. 6000 Kbps is very definitely HSDPA. In it's first release, HSDPA was sometimes called 3.5G, whereas UMTS without HSDPA would have been base 3G. The second release of HSDPA is where we go to HSPA+ and "4G", increasing speeds to 42 Mbps.
If all of this is very confusing, then I apologize, but I'm not really surprised. This is why they apply names like 3G and 4G to it when it's far more complex. If you really want to learn more about the network technology, check out the wiki page for HSPA: http://en.wikipedia.org/wiki/High-Speed_Packet_Access
And yes, as previously mentioned and as you may have gathered from what I posted, HSPA 3G and HSPA+ 4G are the exact same technology, just updated a little, so the battery effect is negligible. LTE 4G will bring an entirely new radio, on top of having an HSPA or HSPA+ radio in it as well, so that's where you get more battery drain. For now, HSPA+ 4G devices won't drain any more battery than HSPA 3G devices.

Now, most HSPA 3G phones don't support 14 Mbps downstream. I think most max out at 7.2 Mbps. Most HSPA+ 4G phones max out at 21 Mbps, or some even support 42 Mbps, however, being that AT&T's network is 16QAM, their network's max speed is 14 Mbps. So really, HSPA 3G is entirely capable of going as fast as HSPA+ 4G on AT&T's current network, assuming you have a phone with a fast enough chip in it.
As for the results you posted, I'm not really sure what to say. You said your UMTS tests gave you 6000-6500 Kbps, but then HSDPA tests gave you 1000-6000 Kbps. What's confusing is that whatever app you are using is posting random labels on the network which are all technically correct, but only confusing people. 6000 Kbps is very definitely HSDPA. In it's first release, HSDPA was sometimes called 3.5G, whereas UMTS without HSDPA would have been base 3G. The second release of HSDPA is where we go to HSPA+ and "4G", increasing speeds to 42 Mbps.
If all of this is very confusing, then I apologize, but I'm not really surprised. This is why they apply names like 3G and 4G to it when it's far more complex. If you really want to learn more about the network technology, check out the wiki page for HSPA: http://en.wikipedia.org/wiki/High-Speed_Packet_Access
And yes, as previously mentioned and as you may have gathered from what I posted, HSPA 3G and HSPA+ 4G are the exact same technology, just updated a little, so the battery effect is negligible. LTE 4G will bring an entirely new radio, on top of having an HSPA or HSPA+ radio in it as well, so that's where you get more battery drain. For now, HSPA+ 4G devices won't drain any more battery than HSPA 3G devices.

Boom! Better explanation than me lol. Sorry for my post not being long enough, i am at school. I was trying to get to what he said.
I thought I can connect my 4GS onto the other UMTS network, but its max was HSDPA:9 (HSDPA:8 in JB).
Other phone such as Photon Q didn't have problem in connecting with HSPA+:15
Do I have to manually enable something? I believe this phone's potential is better than this
My carrier is using 2100MHz band, and my baseband ROM is a new one.
Is this info relevant : ?

If your carrier is using the 2100MHz frequency, this phone should have no problem using HSPA+ with it. When I travel to China, I use a China Unicom SIM in my MT4GS which enables my phone to use their 2100MHz HSPA+ network without any problem. Back at home in US, I use T-Mobile SIM.

Thanks, I don't know what causes this...
So, you are seeing H+ (HSPAP:15) right? All I can see with various ROMs are only 3G and H....
Do speed tests, symbols don't always mean what they say after all
Sent from my Nexus 4 using xda premium
just tested: only around 3Mbps whereas other hspa+ phone got 9Mbps...
Is there any hidden menu to tick this on?

The stock ROMs are configured by HTC/T-Mobile to display 4G when it has a HSPA+ connection. Other ROMs, however, will display 3G or H (depending on the ROM) for HSPA+. So, if you see 3G, H, or 4G, they are all HSPA+ connections. This phone operates data in the G (GPRS), E (2G or EDGE), and 4G/3G/H (HSPA+) modes. Depending on the carrier, it can perform up to 14Mbps HSPA+ but of course, you would rarely see that fast in the real world. It does not operate at the 21+ or 42+ levels of HSPA+.
I'm on a stock-based ROM (Miktouch), when I'm home on T-Mobile, I see 4G. Also, when I'm in China and connected to China Unicom, I see 4G.
I've never seen "H" on this phone, it always shown 3G or 4G (using stock ROM, just de-junked and rooted by myself)
IIRC speed test results, I had best down speed exceeding 14+Mbps on Wind in Vancouver and Toronto areas, but in US it almost always was 3G only (but then I was usually outside any large cities).

Thanks for the input, if you are using non-stock rom, still would you let me know what the following says in the most normal case:
setting - phone - status - mobile network type.
In my case, it's HSDPA:9, which seems obviously non-HSPA. Other phone shows HSPA+:15 or HSPAP:15.
Am I missing something, or HSDPA:9 can be also considered as a decent HSPA+ ?
I'm kinda downshifting toward MT4GS recently as I love its small form factor, but somewhat at a loss due to this limitation, thanks.
