Switching between 3G and HSDPA - Nexus One General

Hey I was just putting this out there and seeing if its just me, or an issue on my phone. I have recently rooted my N1 using amon-ra's recovery and I put on Cyanogen's lastest mod, and I'm at the new ERE36B with the new radio. When I got to work today where there is 3G (I live in the US btw), my phone says I'm on 3G. But whenever I use an application that uses data, my phone switches to HSDPA. I'm just wondering if its an issue, if 3G or HSDPA is faster, or just something that is caused by the new radio...? Anybody with any ideas?

What you're seeing is normal.
3G = UMTS
H = HSDPA
Of course, HSDPA is technically faster but as of right now, there's not that much difference between 3G and HSDPA until towers are upgraded with more bandwidth.
Cheers,
Kermee

HSDPA is regarded as 3.5G in UK atleast...auto-switch when application demands it.

3G on HTC TOUCH HD In NYC

Not trying to start any problems with my first posting but, The 3G icon on my touch hd has change a few times during since I purchased it, Does anyone know if this has been caused by any changes with EDGE.
What do you mean by has changed a few times? You never got 3G in New York did you?
The 850mhz bandwidth was converted from 2G to 3G. http://wmpoweruser.com/?p=2195
"AT&T is apparently changing the 2G and EDGE band, from its current 850Mhz to the weaker 1900Mhz. What that means, is that devices without 3G capabilities, like the original iPhone, will have to cope with the reduced coverage that the new 1900Mhz band has. In the other hand, devices supporting 3G networks like the AT&T Fuze, Tilt, Epix etc, will only benefit from this upgrade, as the 850Mhz band provides much better coverage, especially indoors."
Are you really getting a 3G signal in NYC? If that's the case I'm buying one
My Edge (E)icon has turned to G on about 20 occasions since purchase two week ago.Its not a steady G but will last about two minutes and then goes back to E
Interesting that you posted this. I am using my THD in NYC and NJ areas with T-Mobile USA. I have also noticed that the "E" icon on my THD had changed to "G" at some areas in NYC. But I have not noticed any difference in the data speed.
I just thought that my phone is able to acknowledge the T-Mobile 3G signal, but does not have to facility to access it. I do not know the technicalities behind it.
Isn't the "G" icon for a slower connection than EDGE? i.e. GPRS
yes!!!! now we have firm confirmation that touch hd is capable of 1G and 2G (EDGE)

What this means is that us in the usa better hope that we can enable 3G on the HD soon.
ya. even if tmobile does require both bands, one for down and one for up, it'd be nice if only 1 workded (down) and we were able to at least be able to DL quickly or something. any speed boost is better than none
Just to throw it out there:
Don't know if it is 3G but my "E" changed to "G" on few occasions, for few minutes here in LA, CA (T-mobile). I didn't sample the connection speed, however; thus, wasn't able to tell any difference with the download speed. Edge is good enough for my usage, tbh.

G = gprs 1G which is not 3G and it's slower than Edge 2G....
When I look at the G settings
Its says GPRS,3G

You guys...these are the icons you'd expect to see on your HD for GSM coverage in order of speed:
G - Normal GPRS data
E - Enhanced Edge data
3G - 3G coverage
H - HSDPA, 3G turns to HSDPA on some networks while downloading data then switches back to 3G a few seconds after data use.
If you are seeing a G on the top bar, it means the HD is in the slowest GPRS data rate mode.
Thanks for the clarification, guys; I thought so. Oh well, no need for wishful thinking, then. 2G or not 2G...blah, curse you Hamlet!

max speed technically...(at least in Germany)
GSM:
G --> 56kps (0,05MBit/s)
E --> 256kps (0,25Mbit/s)
UMTS:
3G --> 384kps (0,38Mbit/s)
HSDPA --> 3,6; 7,2; 14.4 Mbit!!! (depending on operator) --> sometimes called 3.5G
LTE (long term evolution) --> 4G (Generation)
coming in 2010 from 25Mbit onwards
using opera, just for surfing, i think EDGE is enough. (without using flash in opera)
regards
irm
p.s. @galaxys: the old analog network is to be considered as the 1st generation; GSM (incl. EDGE) is the 2nd generation. EDGE is some sort of speed upgrade like HSDPA for UMTS.

Your saying that it said 3G on the top of your screen not just G? If so can you post what rom/radio you are using?
You can find this in settings/system/device information

Is this on the top bar or is it the popup network setting bubble? Take a pic for us...
There is a setting, probably hidden and changable via Advance Config and/or HD Tweak where if a network has 3G capability then it shows "<network> - 3G" (I disabled it via one of them)
This is regardless of whether your phone itself can handle the 3G network, which in the case of Touch HD it cannot as the device does not support the frequency of US 3G bands
Mine shows "O2 UK - 3G" for this reason regardless of whether it says G, E, 3G or H at the top of the screen.
Additionally, the "generation" things are as follows:
- - GSM - 1G
G - GPRS - 2G
E - EDGE - 2.5G
3G - UMTS - 3G (surprise surprise)
H - HSDPA - 3.5G

UMTS vs HSPA indicator?

Hey - so, I searched for an answer to this, but couldn't find one.
Is there a way to determine whether you're on HSDPA or UMTS on the Nexus One? T-Mobile USA is supposedly all 7.2Mbps HSDPA, right? I'm getting download speeds of max 700kbps in Minneapolis, MN.
Most 3G towers havent had their backhaul upgraded to support faster speeds I only geet 700-1000kbps down at my house, but in downtown DC i was getting 3mbps+
Just go to settings, about phone, status and it says UMTS or HSDPA.
In CM-5.0 beta it shows H for HSDPA and 3G for UMTS.
Ah, thanks for explaining that. I can see that I'm getting HSDPA if I'm in the middle or just after a big download - seems to switch to it temporarily as needed. Or maybe I'm imagining it.
If you go to Settings>About Phone>Status, it will either say Edge, UMTS, or HSDPA, depending on what you're connected to. I usually get UMTS when I get 3G, although I've seen HSDPA a couple times as well.

HSDPA or 3G speed?... I go crazy!

I have a question regarding the HSDPA on the TMOUS HD2. I used a Diamond back in Germany and when I was in an area with HSDPA reception it was indicated by a "H" in the taskbar. Now I am using the HD2 in Baltimore. From what I`ve read there should be HSDPA available arround here (especially since I am in Downtown B`more) however I only get the 3G symbol in the taskbar. I have also been in DC over the weekend and it was the same only 3G. But I am quite sure they have the HSDPA network available there. Does that mean my HD2 doesn`t get the faster HSDPA speeds at all?
I did a speed test using mobilespeedtest.com and IE.8 teethered WiFi connection on a Windows 7 system. My results in Downtown Baltimore are: "Your speed: 1428.571 Kbps Your latency: 0.561 seconds Transferred 100 KB in 0.56 seconds". With a 4 bars 3G symbol instead of a H in the taskbar. Aren't this speeds you would expect on a HSDPA network? I am running the original stock ROM on my HD2 by the way.
I am pretty sure most carriers use 3G with hspda enhancements, aka 3.5g, which would allow the speed above 3G's cap (364 kbps). As far as why your phone states H instead of 3G, it is dependent on the phone and icon set your phone uses. Some roms will show 3G and others will show H.
where do you find the HSPDA settings? I know they were somewhere but I can't find them!
I think the 3G/HSDPA is weird on the HD2. I can sit in one place and watch it change from Edge to HSDPA without moving the phone (and sometimes a random 3g will show up).
It definitely sounds like you have HSDPA since those are some nice speeds. Mine says 'H' and I get around 780kbps, so you're double that. As long as you have a fast data transfer (and you do) I wouldn't worry =)

I was in Las Vegas Convention recently, and witnessed the power of HSPA+.
HOLY CRAP. Why can't we have that speed ALL over the world?
I was always under the impression 3G was better than H. Perhaps it's a good thing then that mine's usually H then! Where does E fit into the speed scale?
E = Edge. the slowest.
actually GPRS is even slower than EDGE
if i remember EDGE = 500kbps
GPRS = 360kbps
GRPS = 2G
EDGE = 2.5G (sorta)
3G = 3G
H (HSDPA) = 3.5G

So my 3g doesn't work...always switches to HSPDA and then works.

Title says it all. When i have NO HSPDA I become screwed and I have to revert to EDGE otherwise I have no data connection. I haven't tried it out of town yet, but it's ridiculous. It says I'm on 3g, but then switches when I start a speedtest. Is that just because I'm always in HSPDA? Any ideas?
I'm on the Desire ROM. I don't think it's the rom though, because this happened on Cyanogen.
HSDPA is only on when necessary, when it isn't, your on 3G. You're in an HSDPA area, so when you use data your carrier bumps you up to HSDPA.

Assuming you're in the U.S. and on T-Mobile, this thread covers your issue:
3G --> H Data problems
Cheers,
Kermee
Ahh much thanks. So in theory if I leave the HSPDA area my 3g will work because it isn't trying to switch?

If you leave an HSPDA area and only UMTS (3G) & EDGE are available, then in theory, yes. The data will transfer over 3G or EDGE. It's normal for the N1 to "idle" with the "3G" icon, but when you're actually doing data transfer, it'll switch to "H" if it's available.
In other words... nothing is broken. =)
Most people are confused by the "H" because on the *Stock* ROM, the "3G" icon doesn't differentiate between "UMTS/3G" and "HSPDA"... It'll always display 3G with either technology. The *Custom* ROM's differentiate which technology the handset is talking with the tower in regards to HSPDA and UMTS.

HSPA is not working on Virtuous 1.0.0

Hi All,
I'm getting a very weird and annoying issue regarding HSPA on Virtuous ROMs.
I found that H is not working properly in the same place where it got to work on Stock ROMs.
I'VE READ ABOUT THE FAQ ON THE ISSUE:
Q: I used to see HSPA+ (H) connectivity with the stock ROM, where Virtuous shows me 3G in the same area. Why is the data slower?
The stock T-Mobile ROM lies about data rate and displays H even if you are in a 3G-only territory. Virtuous displays H only when you actually have HSPA+ service.
HOWEVER, I DON'T THINK THIS IS AN ANSWER FOR ME. IT IS VERY WEIRD THAT HSPA NETWORK (shown as "3G+" in virtuous 1.0.0) IS TRIGGERED EVERY TIME I MAKE A PHONE CALL. However, I'm not able to start H by opening a browser, etc which triggers a data transfer.
Therefore, it should not be a network problem. Also, when I switch back to stock ROM, the HSPA is working properly.
May I ask for your kind help? Thank you in advance!
P.S. I'm using:
HBOOT: ENG S-OFF 0.84.2000
Radio: 26.06.02.27_M
ROM: Virtuous 1.0.0 with htc kernel (also tried using Std and Adv kernels but problem still exists)
i think that the 3g+ is H
cause i get H speeds when it is 3g+
Yea same problem
When I switched to Virtuous even 0.9.5, I no longer have HSDPA speeds nor HSPA+.
P.S. im running 1.0 right now
anyone plz?
No problems here - I get the 3G+ everywhere I used to get H.
Also, you mention that HSPA is working correctly when you switch back to a stock ROM - that's probably not true. The stock ROMs show an H whenever you have *any* 3G coverage (whereas pretty much all of the custom ROMs differentiate between '3G' and '3G+/H'). So when you see an 'H' on the stock ROM, you have no way of knowing whether it is 3G (like you're seeing on the custom ROMs) or if it is, indeed, HSPA+.
Menu - settings - about phone - network
HSDPA
It is working.
Pretty sure he's using new icons, in the latest roms. There's no issue, its just using a different icon to show the same thing.
It's just the icon, they really don't differentiate between the speeds.
Yea the rom is based on orange and they use 3g+ and t-mobile uses HSPA... well speed should still be the same
Sent from my HTC Vision using XDA App
To clarify, I do know about the 3g+ icon issue.
My problem is that I can only get UMTS after switch to new ROM. No 3g+ no matter how much data I transfer.
The most weird thing is that 3g+ is triggered only when im making a phone call.
Im sure its not a carrier cheating issue because i was able to get hsdpa in *#*#4636#*#* mode. After switching to virtuous i only get umts.
Thanks all who was keen to help and reply!

I am having the same issue you are...
Im stuck on UMTS HSDPA nor HSPA will load... I did a nandroid restore and now it wont get off UMTS
EDIT: I am running 1.0.1
EDIT AGAIN: Updated to Latest Radio and everything is back Online!
