Hi guys,
I noticed that 4G (HSPA) drains my batter far more than 3.5G (HSDPA).
I noticed this because all day yesterday I was getting H only not H+ and I noticed my battery drained less than when its primarily connected to H+.
Is there a way to turn off HSPA (4G) but keep HSDPA (3.5G) active?
Thanks.
You are confusing yourself.
HSPA and HSDPA is same thing.
HSDPA = High Speed Downlink Packet Access (Downlink/download part of the HSPA)
HSUPA = High Speed Uplink Packet Access.
HSPA+ = Evolved High Speed Packet Access (faster)
All of these are 3.5G only. Some american carriers like to call HSPA/HSPA+ as 4G but its not.
Basically if network sometimes looses HSPA+ connectivity for short period due to network glitches or as per area sometimes. Thats why you were getting just H and not H+ for short period.
Nothing more to it. Phone is HSPA+ ready so if your network supports it, it will default to HSPA+. You can force it to be in EDGE mode, thats it.
Correct. HSDPA and HSPA+ (what he called 4g) is quite literally in every respect the exact same thing. Literally, they are both 3.5g. The battery drain was likely coincidental. More tests would certainly be needed.

Nope, HSDPA and HSPA are the same, as HSPA is just a container name for HSDPA and HSUPA. HSDPA+ is up to 84Mbit and HSDPA is up to 14Mbit.
Hmmm so apparently I cannot seperate HSPA from HSDPA as they are the same thing.
HSDPA + HSUPA = HSPA
So does that mean previously the upload rate was not as fast as the download so they introduced HSPA which combines a fast download (HSDPA) with a fast upload (HSUPA)?
Because it appears I can disable HSPA (HSDPA) but dialing *301279# and turning off HSPA which will give me 3G only.

i thought the nexus s doesnt have HSPA+ bands? confused here
It doesn't. It only supports theoretical d/l speeds of 7.2 mb
Sorry new to tmo, is the phone on hspa when it displays an H instead of the 3g or E for edge?

HSDPA is technically 3G.
It will only flip for custom ROMs. The stock ROM will say 3G on both UMTS and HSDPA.
NS does not have the hardware capability to operate on HSPA+. H in network is HSDPA, little snip from my other post.

HSDPA and HSPA+ is not the same. As HSDPA (high speed downlink packet access) is considered 3.5G by today's standard and is capable of 7-14Mbps using UMTS. Where HSPA+ (high speed packet access) is 21-42Mbps and sadly due to FFC changing standards its now considered 4G.

Now back when 4G wasn't used so freely H was fine for HSDPA but now since we have HSPA+ only way you can actually know it if you looking directly at the mobile network type. So from H itself you won't actually know if you are using HSPA+ or HSPA only way is if you install widget that display network detail on panel.
So just curious, I have this feeling that all 3G connections say H+ on the Atrix. I am at home on an AT&T 3G Microcell and it says H+ on my phone and I know for damn sure the Microcell doesn't support HSPA+ speeds.
Any input?
It will display the H+ on every connection besides 2G (edge).
Probably means HSDPA, which most of ATT's 3G network has (the 7.2 network)

Nope.
The correct answer is: AT&T has turned on HSPA+ connectivity on all towers, even if the backhaul is not there to support it.
So, this means that if you have a HSPA+ "4g" device it will show H+ irregardless of if the tower is actually broadcasting HSAP+ speeds.
Yea but a microcell device doesnt support HSPA+ thus there is nothing to turn on...

Ya, that's not correct at all. There are plenty of user towers (microcells) that haven't been patched or "turned on" for HSPA+ and they're still showing the "H+" in the top.
The reason is because AT&T 3G *IS* HSPA...so instead of saying 3G it just says H.
iv owned my atrix for around a year now and iv always had a small problem but just brushed it off my shoulder asif its how the phone should be, although this may be on my carriers side of things.
Im in the uk and i get signal from T-mobile and Orange as there the same company and share satellites but iv always noticed my phone signal status is really missleading, this is how it goes
normal full bars
full bars with 3G next to them
full bars with H next to them
when on the normal full bars i can barely make a call or send a text, after a few retrys it eventually gets there but otherwise says there is no network, so why is it saying i have normal cell data?
then when im on 3G which is supposed to be a half decent data transfer rate, i can call and text perfectly fine but if i try to open a webpage or facebook/twitter, it takes a painfully long time asif to say the 3G is actually cell data or something, its that slow i give up if i see 3G on my phone that means to me that its unusable for anything other than calls and texts...
then theres H+ which is lightning fast.... calls and texts once again are perfect, and when i load a webpage or facebook its faster than my wifi at home... the problem is i rarely even get this H signal unless im around a built up area like a city centre...
what im trying to get at is that although my phone is labellingg the signal as certain things it seems to be getting mixed up?
normal bars fells like it should be "no signal"
3G feels like it should be "normal cell signal"
and H feels like it should be "3G"
im not sure if i get 4G over here in england aswell before anyone asks but my H is alot faster than the 3G on my friends iphones, my friend who also has a sony xperia S also has this same confusing problem..
iv always just wondered why they seem to be labelled wrong, or is 3G just awfully slow and cant handle todays smartphones data?
any answers and discussion would be helpfull.. thanks
Hi, can I just clarify with you which device you have?
Do you have an Atrix 4G from AT&T or do you have an Atrix from Orange/Tmobile/Simfree?
First of all, you should not get confused with the term 4G.
AT&T use the term 4G incorrectly. Their network is HSPA+, which they call 4G.
In the UK, all of the networks are now also using HSPA+.
Another point, if you have a EUROPE model Atrix (Not Atrix 4G) you have more 3G frequencies available to you i.e 900mhz (disabled on Atrix 4G).
You should also be getting the following symbols on your phone (check to see if you have disabled 2G)
G, E, 3G, H (or H+, I have the sim free, it has H instead of H+)
Let me just term everything for you simply:
GSM aka 2G, normally all calls go on this when enabled:
G = GPRS. About 32kbps
E = EDGE. In theory 236kbps but never seen this speed.
UMTS aka 3G
3G = 384kbps theoretical maximum
HSDPA/HSUPA/HSPA/HSPA+ aka 3.5/3.75G
HSDPA/HSUPA or HSPA as its also known = Max theoretical speed 14.4mbps
HSPA+ = The upgraded version of HSPA, also described by the USA as 4G. Theoretical maximum 42mbps (which uk networks are supposed to be rolling out at the moment)

ahhh i see thanks for clearing it up! well i have an unbranded motorola atrix from england so it must not be a 4G but i do get H+ signal
would there be any reason for 3G being slow then?
3g is umts and as already stated above, that's 384kbps = 48KByte/s which is very slow for todays standards. It's like isdn speed, not even dsl...

ISDN would actually be 2x dialup aka about 112kbps so a bit slower than that. Just fyi.
i live in the dominican republic and i only get H. how do i get H+?... whenever i try to access my 4g settings gives me the error "the application settings com.android.settings"

Go to System Settings, About, Status and look at Mobile Network Type. HSPA:10 is the fastest the Atrix supports and is not Evolved HSPA (H+). I was thinking the same as you on this until I researched. My only wish is the we had an indication of all the different HSDPA speeds in the status bar without having to look at the mobile network type. Remember, your provider you not support HSPA:10.
Take a look at the following If you want to read up a little bit: http://forum.xda-developers.com/showthread.php?t=1912716

Hey everyone,
When I bought the international version of Samsung Note II, the ad specifically said it would only work with EDGE lacking 3G, LTE capabilities. I know Tmobile is in the process of upgrading their towers to extend their 3G 1900+ coverage.
Funny thing happened today in Los Angeles, USA-- while I was walking my dog near a cellular tower I saw H+ on my phone (hooray no more E!). I immediately ran speedtest and had 16MB download speeds compared to my 200kb Edge. As I walked away from the tower, H+ became H which downloaded @ 7MB.
So were all these claims/scare that the international version of the Note 2 will "never" have 3G/LTE based on baseless assumptions given the lack of release in US? I'm assuming H+ = 4G/LTE?, H = 3G and E = lame.
Let me know what you guys think!

The International does NOT have LTE.
It does work on AT&T's HSPA+ network and on T-Mobile's EDGE network (2G)
However, if you're in an area where T-Mobile has already refarmed the 1900 MHz spectrum, then you will see HSDPA and HSPA+ speeds from T-Mobile (FauxG). However, in 2013 when T-Mobile starts deploying their LTE, you won't be able to get on that network, however, T-Mobile is planning on refarming the 1900 MHz spectrum for HSPA+ and 3G, so in that regards, if your area already has begun the refarm, then from now onwards you're only going to see more and more places where you pick up HSPA+

H+ is not LTE, it's just being marketed by T-mobile and AT&T to be "4G"
H+ = HSPA+
H = HSPA
I'm currently on x829 USA variant of the Le Max 2. I've noticed that for me switching to H+ gives way faster data speeds. I'm in USA on Metro PCS. I'm using t.mobile apns. Just thought I would let some people know, depending on your area H+ may bring faster data speeds. I've noticed this on all Roms. I guess it depends on your location and where the cell towers are located and traffic congestion. What are your thoughts?
Bottom is LTE with great upload speeds. Top is H+ with better download speeds. Basically when I switch to H+ I can stream Instagram videos no problem without loading. It totally depends on the area your in as well I know.
H+ is 3G HSPA+, it is much slower than 4G LTE.
my area the (t-mobile) LTE network speed is over 100mpbs all the time ....

?!?! This sounds insane! What's the trick? Do you bribe T-Mobile in your area with cookies?!
Max speed of H+ is 63 Mbps. LTE is much faster but it depends on your area coverage.
