Hspda = HSPA+?

Or is that different?
I am reaching 400kb/s is hspa+ faster?
sent from planet snarf

its pretty much the same thing wtih different speeds. as far as you're concerned, it's the same thing when it comes to what your phone tells you (as long as you're provisioned for 4g with att). chances are the market that you're in (if it's a city or outside a major city) will have 4g (HSPA+), but it may or may not have the backhaul to support higher speeds. backhaul is pretty much just fiber optic cables to the towers in your areas that allow your upload and download rates to get to "4g speeds".
http://en.wikipedia.org/wiki/High_Speed_Packet_Access

3G - UMTS
3.5G - HSDPA/HSDup (sometimes referred to as HSUPA)
4G - HSPA+
3 different networks, providing different speeds. However, I think that even when connected to HSPA+ you will only see download increases, you will still be using HSDup.

will umts show up as H+ still in the upper ICON?

No - UMTS should show 3G. However different ROMs will display different icons when connected to differnet networks. Don't rely on the icon. You can check which network you're connected to by going to settings - about phone - network (or status) and see what network you're actually connected to
Except in stock roms or roms built from the stock rom where the chef hasn't changed the icon. Stock roms will show H+ when connected to umts. Marketing ploy. F you, ATT

HSPA+ is NOT 4g. LTE is 4g, even though it technically isn't. HSPA+ is jsut a software upgrade to HSPA. the only reason they needed to do the backhaul upgrades were to be able to handle the increased bandwidth.

Checking HSPA status

Hi everyone!
I'm using Nexus S 9023 on Softbank (Japan). I used speedtest.net and the speed was extremely slow, only 0.75Mpbs for dowload and 1.05Mbps for upload.
I wonder how to check if my phone can use HSPA or not? Or is it softbank slow or Nexus S doesn't support HSPA on softbank?
Note: I try to download some file and check the network status. It only shows UTMS

You are aware that you are sharing the cell bandwidth with all the Japanese people in same cell, right? Just remember that everyone of them is surfing 2chan just when you do your speed test

It can use HSPA and it does, obviously. Standard UMTS would only give 384kBit/s downspeed max.

HSPA is part of UMTS.

Thanks for the thorough reply.
I'm from Vietnam and the networks in my country typically reaches around 3.0Mbps for downlink and 1-2Mbps for uplink. So I thought in Japan in should be somewhat better.

I can only say that Softbank Mobile has a somewhat turbulent past. It was first J-Phone, later bought by Vodafone, which lost customers.
There is that passage on wikipedia that says "Vodafone 3G failed to attract subscribers because Vodafone cut back investments in 3G services in Japan in 2002/3".
I don't know how to interpret that statement, but it could mean that they didn't put enough money into the network.
Anyway, they sold the business to Softbank in 2006 and I have no idea how things evolved from there.
However, the lowest specified HSDPA speed i found specified is 1.2Mbps (for the whole cell, or maybe for 5 codes, see table at https://secure.wikimedia.org/wikipedia/en/wiki/HSDPA)

I do get speed more than 384kbps even when I am speed testing and the phone information shows that I am on UMTS, I am just guessing that the update is not that fast. Coz I do get HSDPA like 50% of the time.

Data network modes - 3G or HSPA

My phone does something weird. When the data mode, shown beside the battery icon, is shown as 3G, no data transfer can be made until it is changed to 'H'. This gets very annoying.
The problem is that it stays at 3G until I want to do some data transfer, then it changes to 'H' which takes some time.
Anybody gets this as well? Is there anyway to prevent this?

H means hsdpa,which is High Speed Downlink Packet Access. It is 3.5G. And it is faster than 3G.

I had this very same issue in UK (Virgin pay as you go)

Same issue with o2 Pay Monthly, although it generally switches to H quite quickly when data access is required.

Correct me if I'm wrong. H means HSPA, which is 3.5G, and 3G is 3G in itself, and G is 2G? I thought 2G didn't allow data transmission? So isn't 'G', 3G?
I understand HSPA is supposed to be faster than 3G, but the problem is that 3G doesn't allow any data transmission.

"WCDMA"
H = HSPA = 3.5G
3G = 3G
"GSM"
E = EDGE = 2.5G
G = GPRS = 2G
All of them allow data access, or should do anyway.

Both 2G and 3G allow data access.

No, "G" is not "3G". "G" means GPRS (General Packet Radio Service) and is an old standart to transfer data via GSM. It is, in fact, the slowest ond one of the oldest.
There are two networks, "2G" which is "G" or "E" (EDGE which is is a litlle bit faster than "GPRS" - and "3G" (now even "4G" ) which is a high spead network. "H" should mean "HSDPA" or "HSPA"
Oooops, to slow.
In addition: Via 3G you can do data connection and phone calls at the same time, this you can not do in 2G

Your phone will check to see what the best connection available is before downloading. The wait is down to your network provider's service and availability. And possibly your radio. It's not that it wont download on 3G. It will. It's just that 99 times out of 100 if 3G is available, so is HSDPA so it'll go for that one over 3G every time. Unless you are on my network provider. Then you'd get better consistent data transfer over a piece of wet string.
You could go into your phone setting and choose 'WCDMA only' if you generally have good coverage and want to cut the wait out?
Dial *#*#4636#*#*, from the resulting menu select 'Phone Information' then scroll to the bottom and change the drop-down menu to 'WCDMA only'.
Does that help?

Tip:
You can also do this without dialing a code:
Got to settings/wireless & network/Mobile network/Network mode
So you don't have to remember the code if you want to change settings

I tried this. For now it seems that it is stuck at HSPA now! Thanks! Am I right to assume that under WCDMA only mode, I either get HSPA data or no data at all? The phone will not go to 3G or 2G right? (there's no 2.5G here)
Thanks to the others who clarified the 2G,3G,3.5G terms. I understand it more clearly now!

WCDMA only means you will only have HSPA and 3G connections. You will not have, as you wrote, 2G. 2.5G means EDGE which is still a 2G connection but a little bit faster than GPRS, and right, you will not have that.

HSPA includes HSDPA and HSUPA. I really don't know the difference between them.

HSPA is faster than HSDPA, and HSUPA is the standart for uploads. You should visit Wikipedia for detailed information.

Is 3G faster then 4G?

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.

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.

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.

Tmobile LTE slow data

I have the note 5 and yesterday my LTE speeds slowed way down. From a normal 26 mbs to about 1 mbs today. I did dial *#2263# and changed my preferred LTE band to 4 but i am not sure what band i was on before.
I am assuming that the tower near me was updated to band 12. Is there anyway to select another band? Or tell which band I am on?

T-Mobile will throttle your data if you pass the cap on your plan.

I'm sure he would know if he was being throttled because the 4g lte icon on the status bar would switch to 2G. Sometimes their might just be a lot of people connected to the same tower.

No speed issues here, LTE or WiFi.
I'm located in a Band 12 area, so I used the service mode to tell my phone to prefer it over Band 4. My speeds went from ~20mbps in a particular area to over 70mbps, without moving an inch.

I noticed slower data after flashing the new modem

I got throttle last month and lte was showing.
