3g? 3.5g? Hsdpa?? - G1 Q&A, Help & Troubleshooting

Hi everyone,
my data plan covers 3G and also HSDPA......im currently using the JF1.51 and when i use the go online with the device, it only shows the 3G logo....... does cupcake only cover up to 3G instead of HSDPA?
if anyone knows, please tell me, thanks alot....
p.s. i tried the Hero rom last month and after setting the APN, it showed "H" instead of "3G".....does it mean that the Hero rom has "unlocked" the HSDPA function?
thanks alot

The H in Hero is just a custom icon by HTC. All Dreams are capable of HSxPA regardless of whether that icon shows up or not. As for the carrier side, you are most likely on HSDPA. If you are on any T-Mobile network or most Asian networks (Taiwan, Japan, China) they are HSDPA. An easy way to verify is to start a speed test. Any speed higher than 384Kb/s downstream (384Kb/s ~= 48KByte/sec) means you are on HSDPA.
If all that was too complex, just assume you are on HSDPA.

I had thesame issue with the Touch Pro on sprint, it only shows the EVDO icon when connecting, however, sprint is even advertising their new 4G network but I have not seen my phone ever go to 3G or above. I thought something was wrong with my phone...
I went to sprint to get it exchanged because I bought the phone for the faster service. I was given a big spill over the offered network on sprint.
Your answer: Basically, some icons are not unlocked in some roms or are not even included depending on your service provider. This being said, you will most likely have to have the custom rom to get this to show up on your phone.
But even if your phone does not show that icon, test it and see if it uses the technology.
- What I did is took my TP to my friend who has the new Iphone 3G and we started the YOUTUBE app and loaded the exact same video. Even though his showed the 3G icon all the time and mine only showed EVDO, my phone brought the video up almost 5 seconds before the Iphone ever did, not to mention the quality of video is so much better.
Ok, I see that I am rambling, I hope that this helps though, however, if I have been informed incorrectly, please someone correct me because I would like the other icons too, just for my aesthetic needs.

thanks for the reply man, u gave me some ideas to what i need to do....
iv just tested out the jac hero (mod version from Nismo)....my gprs connection varies from the "H" icon and the "3G" icon......somehow i assume that it is running in between both speeds?
haha,
once again, gotta thanks to the bro who replied real quick....u r good guys unlike some members in the xda who arent willing to help with simple questions

i got an ev icon
this is kind of in relation to this thread...i was running one of drizzys hero builds and i was in new york one night...this only happens when im in the village..dont know why but anywho...i got an ev icon..im assuming that was for evdo cause i heard the new hero dumps have cdma support..dont know if im very wrong but the icon switched from 3g to ev and when i got on the browser i was impressed...my connection was flaming fast i mean ridiculous ive never seen nething like it...can anyone elaborate

Your rom can't give you cdma support, that is hardware related. And the G1 is only on GSM networks not any CDMA's so you might have seen some other type of icon because it is not possible to get EVDO on any G1.

these were my thought exactly...but i promise and swear to you it said EV not evdo but EV and my connection was faster than ive ever seen before..im going to get that screenshot capture nd next time wen i go to the spot where it happened i will show you...dont know how its possible or what it was..but it was super fast

I aint saying I don't believe you, I just know it is impossible to get CDMA on a G1 no matter what rom or dump. What I would assume is it was HSxPA and the rom you used had a dump from the sprint hero. That could explain why you had a EV icon and is most likely what happened. Like the other guy said his touch pro had a EV icon although it was getting 3G, so since you do have a 3G icon and it switched to EV it is probably because the area you were in had HSxPA.

yea that makes sense but wow was it fast..thanx for the input

HSUPA gets like 7.2mbps so it is like cable almost, I'm not sure about HSDPA but its is pretty quick too.

how would i get this speed on my g1? im on tmobile with the android plan..

Go somewhere that has t-mobile 3g coverage. That is the only way to get the speed you inquired about. If it's not in your area yet, be patient. They are doing alot of expansions to their network. If you live in a rather remote area (ex: somewhere that doesn't have EDGE coverage) don't hold your breath. It's gonna be a while.

HSDPA and HSUPA are both 3G telephony protocols in the HSPA family. They are two parts of the same thing. HSDPA (Downlink) provides up to 14 Mbit/s. HSUPA (Uplink) provides up to 5.8 Mbit/s.
btw HSPA (or 3g as US carriers call it) is CDMA. Though different from CDMA2000(EV-DO) which is what you were refering to, UMTS is still CDMA based.
And to those confused about the Icons. 3g and HSPA are two names for the same thing. The icon you see simply depends on what the common name for the technology is in the locale the rom was originally designed for. Google based roms usually show 3g whereas HTC based roms sometimes hav H instead. The only difference is the icon.
as for those with EV icons. They are probably from the samsung galaxy system dump. Not to say it's not out there, but I haven't heard anything about a sprint version of the hero rom surfacing yet.

Ohh I guess I didn't have it right. But I know I have seen something about HSxPA gettin 7.2. Damn 14mbits is insane for a cell, I wish I got that in my area. My DSL is only like 7mbits dl and 1.something upload.

Should get it eventually. I only get 7.2 as well, but t-mobile has the whole 1700 band leased, so we might get lucky over the next few years.

AT&T US 3G Not working on Tilt

I'm in an area that supposedly has 3G coverage (Portland, Oregon). But...
My Tilt has never connected to the 3G network. I've gone to many areas thoughout the metro area, power cycled my phone (to see if it picked up new towers) but I never get 3G connectivity. The "3G" Icon has never displayed on my Tilt.
I've tried different radios which doesn't make a difference.
Suggestions anyone?
Wow, a local!
I have HSDPA almost everywhere in Portland (fastest 3G standard). Even with it not enabled, I have 3G in most of the metro area, including Vancouver where I live.
What icon is displayed?
I'm actually in Hillsboro, but it may as well be Portland.
Usually the "E" icon, and rarely I get the "H" icon.
I'm not sure what the "H" represents. I think its HSDPA, but I assume thats not 3G or as fast as 3G... and if it is then what's the "3G" icon all about?
HSDPA is what you want to see! It's the fastest version of 3G, and the newest available.
E is Edge, its 2G, not as fast but not horrible... Until Edge Evo comes out.
The data coverage maps from ATT are usually pretty bad. It doesnt have to say 3G for it to be 3G. HSDPA is 3G (the best) as well as other variants.
Do you notice a hit in your download speeds?
hmmmm... how confusing. If HSPDA is 3G. What's the point of the "3G" icon?
At my apartment I only get 1 maybe 2 bars of service if I am lucky so that means that while I am home "E" is the best I can get (or expect). But...
When I am out and about I get the "H" icon occasionally. Is there a good way to test my connection speed?
Yeah it's sort of weird... Here's a breakdown.

* EDGE (EGPRS)
o EDGE Evolution

o LTE
o HSOPA (Super 3G)

From - http://en.wikipedia.org/wiki/3G
I don't particularly like Wikipedia, but this should help. I'm sure there is a program that will test your connection speed, but you can try something simple like connecting and downloading a cab, lets say Google Maps. Then you can run Google Maps and see how fast you get your satellite image up. There is probably a better way but that should show any big differences.
EDIT: I should add that 3G usually denotes a mix or standards available. It's just a generalization, and the fastest will be chosen by your phone (this is how I understand it)
Also, what ROM and radio are you using?
well in the midwest AT&T was having problems with 3G they dont know why but all of a sudden their networks just failed idk if that is what is causing ur problem but i kept on getting an error saying that the phone couldnt connect to wap.cingular.
Thanks for that breakdown. Gives me a much better perspective.
I've tried a couple of the more popular ROMs. But recently I've been using Q-Mobile 1.2 - It's treated me well. I'm still trying to understand why Dutty's roms are so popular. I can't figure out what makes people flock to his ROM's over the others.
I've also tried out some different radio's. None of them seem to make any improvement (while at my apartment) but currently I am using 1.27.15.32 because I am under the impression that it is the newest radio and therefore should somehow be better.
I'm also unsure if I have the correct data connection settings setup after flashing a ROM. From what I am able to find the only thing I need to do is use "wap.cingular" Then I go into advanced settings and input the OpenDNS servers in for the DNS. Do I need to add any other AT&T specific information after flashing. I've read that there is some sort of proxy information needed as well but its not very clear.
Anywho, what settings for data do you use? What Radio, ROM?

Yeah, I read about that. Aparently AT&T has no clue what happened. And to make matters worse there is more data outages today.
But I'm convinced that my issue is unrelated to all that since I've been experiencing these issues way before the data outages.
I'm glad that helped. I use the Stock HTC ROM 1.56.405.5 with Radio 1.27.12.11 (It's packaged with the radio). It's a legit HTC release, which means very little bugs and it's fast. Flash and hard-reset and you are good to go.

http://forum.xda-developers.com/showthread.php?t=331900
Anyways, I've heard good things about the Q-Mobile roms, but I've been so happy with the .11 radio that the HTC stock works great for me. The .11 radio is also packaged in the stock ATT ROM your device shipped with.
When you first boot, it will prompt you to setup data, and for me it gets all the settings automatially and takes about 5 seconds to do it. Otherwise, I'm pretty sure you just use the wap.cingular, but in all honestly I've never had to do it. I also am not sure why people go crazy over Dutty ROMS. It's almost blastphemy to say that on this forum, and I really appreciate his hard work but they arnt for me either. I like real fast,not too flashy and super usable (and stable, of course, why I love HTC stock ROM's)
I just looked now, my access point name is isp.cingular. Never bothered with it before.
I'll check up on this thread tomorrow, hope this helps you out!
Please ignore this.
Interesting... You make a good argument about the stock HTC ROM. I'll have to try that and see if reception and data speeds are any better.
Although my Tilt came with radio 1.27.12.17 - I've only had it for a couple of weeks so they may have put a newer radio on it.
As far as ROM's go, I'm just looking for something that I can use as a baseline. I don't like programs cooked in. I'd rather have a clean ROM and install what I want. But, on the other hand I do like how the cooked roms often contain the latest updates baked right in.
I'm off to flash to the HTC Stock ROM. I'll let you know how that goes.
Thanks for your help, it's nice to have a local to bounce things off of
I don't care for everything cooked in either. The HTC Stock is pretty bare-bones. The only thing I would recommend adding is Nadavi's upadted camera, dumped from Polaris...

And of course the Tilt Keyboard Fix...

Also, Youtube and streaming video work out of the box, you don't have to do anything fancy to get GPS working (run GPStest, etc...) and besides that there is not much needed. Any eye candy can be easily added.
BUT, remember to hard-reset after flash! It makes a big difference, at least for me.
Let me know how it goes!

H is faster than standard UMTS, and yes, its HSDPA. You will only see the H while data is being actually sent/received though. When no data is being transferred you will see 3G.

I cant use AT&T internet on certian apps?

It use to work before I had Shaps Rom on mine, now resco apps wont work and on occasion Windows Live Messenger wont work. . . Some other apps are Skype, zsIRC, Coreplayer(Yes I have the 1.1.3 one), some others but you get the idea. What could be the problem? I have the right MEdia Net and AT&T ISP settings.
Anyone? What could the problem be?
It would probably help if you posted your set up, i.e. rom/radio/os versions...
Ah, well, I said shaps rom. And I have the radio ver: 1.27.12.17. It could be the radio, but now I am only getting edge speeds, when I am in a city with all 3G and edge in the suburbs and ghetto areas?

oh? i thought schaps had more than one rom released.
with my current setup i haven't had any problems or complaints with edge or 3g.
so, how's your rom coming along?
Oh, lol thats what you meant. . . Its the 4.31 one. I dont know. I havent been able to use certian apps. . . and a moment ago it didnt have any connection and now it does and it jumps from edge to GSPA and then sometimes I cant have 3G back and when I do it messes everything up, like the carrier logo says AT&T 3G instead of regular AT&T and it would change the HSPDA symbol to 3G and sometimes its normal with the Hspda symbol? Why does it do that? Well I'm off to be its too late here anyways. ., it could be a network problem IDK but I hope it corrects it self in the morning.
What part of town are you in so maybe you could help me?
the band switching problem is my favorite. you are lucky to only get that now. try turning off your band setting from auto to either gsm or 3g, that worked for me. you could always change your radio and see if that helps.
oh, and your apps not working, ..... hard reset yet?
i'm generally all over town during the day, but i live near the uni.
although i don't know how much help i'd actually be.
Tried that and I don't want to start all over after 6 flashes(During the time I flashed to the shaps rom out of the time I've had it). Well, it works now. It could have been my area. UNLV? I am by the community college.

Normal operation of HSDPA is this: In a 3G area the 3G icon will show. While data is being transferred the H icon will show. Once the data transfer is complete it will go back to the 3G icon. I think part of what you are describing is normal oeration.
-Jay
Well, no. My whole town is almost 3G, so I dont think its that and it would say HSPDA all the time even with out data transfers. I think the network had a hiccup yesterday. It only did the 3G icon thing when I would have been messing with the band selection(hasent happened lately it only happened 2 weeks ago).

You should not be on H all the time, even when no data is being transferred. My phone got stuck like that once. A soft reset fixed it.
-Jay
Well not connected, all the time it just says [H], is there something wrong with that? I thought that was 3G? When ever the [3G] symbol comes on the carrier display area not the connectivity area says AT&T 3G and when its normal it just says AT&T.

3G not working with HTC shipping ROM?

Firstly, let me thank everyone who does all the SUPERB work on this site, developing software, ROMs, and tools that us normal users would otherwise never see...
Here's my problem:
I got a Kaiser with the shipping AT&T ROM on it - I'm in the US.
I wanted to get rid of the bloatware and other crap that AT&T puts on the device, and take it back to an HTC ROM.
The problem is, I can only connect to the EDGE network, and I'm only getting 40-60k transfers - I know that with my Samsung Sync (my previous phone) I was getting 1.3-1.5Mbps using the same site to test (http://text.dslreports.com/mspeed)
Is this a limitation within the HTC ROM? If so, does anyone know if newer HTC ROM's (perhaps even with WM6.1) will fix this problem, or do I HAVE to use an AT&T ROM to access the 3G (HSPDA) network in the US?
Thanks in advance for your time!!!
Do you see the icon 3G and it changes to H once you're accessing the internet? If no, you might want to check if you correctly config the connection.
I myself don't trust http://text.dslreports.com/mspeed when it runs on PIE web browser. I did the benchmark on 2 different types of connection, at&t HSDPA and Verizon FiOS* Wifi, and it comes up nearly the same speed 1.3-1.5Mbps.
*I have 15 Mbps download package.
Yes, it DOES do that (Mr President...lol)
What site do you prefer to test the speed of your 3G connection? I was hoping to use Speedtest.net, but doubt that they support mobile.
So, I guess that you're saying my connection is probably just fine, but that the site is problematic?
Thanks for the quick reply, btw!!
- Mark
I don't pay attention too much on speed. But, there are many ways to confirm that you're connected to 3G network.
If the answer is yes for any question below, then you're 3G.
a. Tethering internet via your PC on "internet sharing" mode and make a call at the same time.
b. Stream any audio broadcast with bitrate above 196Kbps.
Enjoy.
Um, where do you live? Pretty much only the major cities have 3G deployed, and even then, it's no guarantee. I live in Minneapolis where 3G was rolled out last November.

I'm in Pittsburgh - I know for certain that I'm in 3G territory, as I just got the Kaiser a few weeks ago, and before that, was using a Samsung Sync tethered to my laptop, and getting 1.3 - 1.5 MBps....
UPDATE
Must have had a lousy signal where I was trying it before - I tried it again, using the same site, and was getting 500-600k - so I guess it's hitting the 3G network, but for some reason, changing the 3G icon to an H, presumably indicating HSPDA.
All's well...can one of the mod's please lock this thread? Thanks!

I have the Diamond w/AT&T

Unfortunately bad news everyone. For some ungodly reason the Diamond is only showing G! Not even Edge! From what HTC is telling me they are only supporting 3G on the 2xxx Mhz band? That makes no sense whatsoever! I am willing to try things if anyone has a suggestion but so far not good! Which is weird because I previously reviewed the original Triband TYTN and that at least did get 3G on and off but always had Edge.
http://mobilitytoday.com/articles/htc_diamond_first_look.html
I don't know why you're not getting edge, thats a an extension of GPRS which works over GSM.
As for 3G/UMTS, it never said it suported anything but 900/2100. There's nothing you can do, HTC already said that there wasnt enough space in the phone for the extra antenna's required to support more frequencies.
isnt edge on 1900 ?
yup it is! I would be willing to look into the registry to see if there is a tweak? Any of you have an idea?
no idea my guess would be try forcing 1900 ?
beyond that i wouldnt know
try different area ?
Edge in the US in most areas is 850Mhz, which is the reason I held off on my purchase of the Diamond.
hmmm
interesting but i had bought a original touch in india and that works in most places that i go in the states and i recieve edge

thats the answer ,,, non us versions of diamond don't operate on 850mhz
so dave did u get an hsdpa signal?
and im sorry u in jersey or nyc?
i forgot
sorry but is there a reg edit where he could force the device to look for 850?
just to see if its hidden..then we can find out if they really left out the radio or not...i really wanted to pick one up ...but if it doesnt have 850 its a no go for me...bummer
No HSDPA signal.. All GPRS!!! 7 hours!!! Call quality completely sucks too..

that blows sorry dave ....so how r u liking the ui any lag?
BTW dave if anyone has that rom of the diamond that was sent out to reviewers (that had the att bands) would be nice
Mine does show the 850Mhz band but thats not the problem the problem is that this phone ONLY supports 3G at the 900 and 2100mhz band.
The UI is very laggy so far. I am going to use it via Wifi and see if that improves the UI. BUT another weird thing is that I just popped my Tmobile sim in and now get Edge?

Tmobile is 1900 only so their EDGE has to be on 1900.

For those who are interested I just posted my first day video feel free in checking it out..
At the begining of your video you say that while a GPRS connection is up your calls go to voicemail? Thats not normal behaviour:
Class A devices, which some new devices are, can make/receive calls without dropping the GPRS connection. Just to be clear, data can still be sent/received over GPRS while you're talkiing.
Class B devices, which all other devices are (except the first few GPRS devices made), can handle GSM and GPRS at the same time, but will drop the GPRS connection while a call comes in, or you make a call. They then resume the GPRS connection after the GSM channel is not in use.
Class C devices, can only handle GSM or GPRS one at a time, and you have to manually switch which mode you want. Only the first few devices ever made or Modem terminals are Class C.
Are you absolutly sure about that behaviour because its not a defined class for GPRS.
PS. best quality video so far. With that great lighting you can see exactly how the 'diamond' is on the back. I think the fact its brand new and super clean also helps
Also it seems significantly faster than the coolsmartphone review.. I guess the extra RAM makes a huge difference.
Has a date been tossed around yet for a possible US friendly version launch? Or is this just another one of those cool phones we won't get to use over here?
I am in the USA .. no phone with only GPRS or Edge can take a phone call while in a data connection.. Only 3G can do this in the USA..
Thank you very much for your kind comments about my video.. We try very hard to deliver a good review. I will continue posting more videos as I continue to use the Diamond.. So far for me this phone in the USA is a dudd..

At the begining of your video you say that while a GPRS connection is up your calls go to voicemail? Thats not normal behaviour:
Class A devices, which some new devices are, can make/receive calls without dropping the GPRS connection. Just to be clear, data can still be sent/received over GPRS while you're talkiing.
Class B devices, which all other devices are (except the first few GPRS devices made), can handle GSM and GPRS at the same time, but will drop the GPRS connection while a call comes in, or you make a call. They then resume the GPRS connection after the GSM channel is not in use.
Class C devices, can only handle GSM or GPRS one at a time, and you have to manually switch which mode you want. Only the first few devices ever made or Modem terminals are Class C.
Are you absolutly sure about that behaviour because its not a defined class for GPRS.
PS. best quality video so far. With that great lighting you can see exactly how the 'diamond' is on the back. I think the fact its brand new and super clean also helps
Also it seems significantly faster than the coolsmartphone review.. I guess the extra RAM makes a huge difference.

well i hate to say it but you should have read up on the specs before you bought it, the phone itself isnt a dud. The DIAM200 will work on 3G 850Mhz in the states and will be released in a few weeks

3G on T-mobile US!?

Yes, I know there is no 1700mhz AWS on this phone.
Got an HK ver diamond last week. Immediately put my sim in and got an "H" icon. Being my first 3G phone I thought Edge was wacky. Later Icon changed to "E", so I thought Edge was finally working right (although surfing seemed fast at first).
Played with it for a few days, flashed to Duttys latest (had 1.37) and 1.00.25.05 radio.
Today while reading through these forums I realized that the "H" meant HSDPA. I can't possibly imaging how that could have been real 3G.
I bought this phone knowing I would not get 3G on it here.
I Know T-mobile is just going live, but I never should have seen that "H". Maybe because I was just a few miles from T-Mobile headquarters? Maybe they were testing something? A bug in the phone?
Any ideas?
everyone now and again i recieve the H icon, even though im not connected through HSPDA and infact it's only edge, i think its just a bug

Amazing but hoping it's real You may want to benchmark the speed and compare with reported: forum.xda-developers.com/showthread.php?t=409147&highlight=3g+speed. Let's know, ok?

I think that pretty much sums it up.
Should it happen again I'll do the speed test.
nah...i think it's just the phone trying to search for signal in every possible band, so it stopped on H for awhile on your phone then go back to EDGE...
