There are no really quick, good places to find out what is what when it comes to those nasty acronyms for different kinds of connections. SO, how do EDGE, UMTS, WCDMA, HSPDA, GPRS?
GPRS general radio packet service - basic data transfer
UMTS Universal Mobile Telecommunications System
WCDMA Wide Code Devision Multiple access
EDGE Enhanced GPRS
HSPDA ?
I just found out that US TM is rolling out a 3G network, which I assume is going to be WCDMA, but they just (a few weekes ago) rolled out an EDGE network. I want a new phone, but I want to be able to use the max data transfer possible, in the future.
Can you use UMTS with and EDGE network? (UNIVERSAL mobile tel.....)
UMTS and WCDMA?
EDGE device on WCDMA?
WHat the hell is going on????
Please help me!!!
no utms on edge networks
nmt (old analog cellphone system) == 1g
gsm == 2g
edge == 2½g
UTMS == 3g
google search's liek this should help alot too
http://www.google.dk/search?hl=da&h...zilla:en-US:official_s&q=what+is+UMTS&spell=1
HTC Hermes on May 2006 (Approx)
This device can use UMTS, EDGE, GPRS, HSDPA TBD, GSM Quadband.
HSDPA : High-Speed Downlink Packet Access (The next step 3G)
Is That True :?: :idea:

Thanx Rud.
But where does WCDMA fit in?
And please don't think I don't try, I use search.com to research stuff, and wasn't able to get a very good description of how they all fit in or not with each other. Thanks ya'll
this may be helpfull

otherwise try using google i have no idear what search.com is but google delivers alot of meaningfull results if you search on stuff like
wcdma vs. UMTS or what is WCMDA or WCMDA faq
I don't care what the other guys said about you Rudeger, you're alright with me! :lol:
Im in New york city, when im in manhatten i get the U for my data connection. But when i get back to brooklyn it goes back to the G. From what i understand the 3g network didnt reach brooklyn as yet (even though its over the river) But my real concern is the G. I was reading the getting started guide and there is a E for edge. but im not even getting the E. I know there is edge because i had the 8125 and edge worked fine. Is there some sort of settings i have to input to have it default back to edge instead of regular gprs?

They way that the 8525 is set up is that there is only 2 icons U for UMTS and HSPDA and G for GPRS and EDGE. As far as I know from selling Cingular there are very few areas left that use GPRS.
The guide's wrong ... Cingular messed it up .. there's on U and G on the TyTN / 8525 ...
- U for UMTS
- G for GSM/GPRS/Edge ..
Some are folks on HoFo thought the same .. but check out your speeds using dslreports.com/mspeed ..
its saying 171 kbit/sec. i guess the edge is working right?
171 KBit/s is definitely EDGE.
The TyTN supports GPRS class 10, which means the maximum downlink bandwith with GPRS amounts to 48 KBit/s (4+1 scheme).
im able to grab U settings.. but only 2 bars
I'm about to give cingular customer service a call and *****.. maybe i can get some credit
yp .. 171 is Edge ...
GPRS is only 50kbps or so .. and 3G 500Kbps and above ..

According to the network engineers the 2 bars on UMTS is normal. I called the one in our area because when it was first turned on I had 4 with UMTS and then it has dropped to a steady 2 bars UMTS.

UMTS is 3G? What is UMTS vs GPRS and Edge?

UMTS is 3G, acutally it's the first official 3G standard, as FOMA's standard was a rather proprietary development.
EDGE is 2.75G and GPRS 2.5G.
Have a look at this table, I found at Wikipedia:
2G
GSM
iDEN
D-AMPS
IS-95/cdmaOne
PDC
CSD
PHS
2.5G
GPRS
HSCSD
WiDEN
2.75G
CDMA2000 1xRTT/IS-2000
EDGE (EGPRS)
3G
W-CDMA
UMTS (3GSM)
FOMA
TD-CDMA/UMTS-TDD
1xEV-DO/IS-856
TD-SCDMA
GAN/UMA
3.5G
HSDPA
3.75G
HSUPA
HSOPA
4G
Frequency bands
SMR
Cellular
PCS
IN LAYMAN LANGUAGE:
UMTS is the first 3G standard, based on WCDMA technology ... you need additional device hardware for it and it's upto 300kbps .. HSDPA (High-Speed Downlink Packet Access) is a software upgrade to UMTS increasing it's speed to 1.8Mbps and above theoratically upto 20Mbps (I think) ... anything above that like HSUPA is not commercially implemented .. atleast in the US.
Cingular's running UMTS/HSDPA right now for it's 3G network .. with speeds ranging from 400-700 kbps (officially) and 1Mbps (un-officially)
do i need software to have my hsdpa work when i have utms service? or will it work by itself?
It's provided by the carrier or your device manufacturer ... very low-level ROM stuff ..
Check out http://wiki.xda-developers.com/index.php?pagename=Hermes_Utils ("SetHSPA") for information, howto enable HSDPA.
Most of 8525s/TyTNs are now shipping with HSDPA enabled already .. that utility was supposed to enable HSDPA on some very early ver TyTNs. ..
Also, your carrier should support HSDPA ...
I have a line with 3G Enabled ......On Jamin..
Is there a way i can trick my jamin to use EDGE as a modem for 3G??????????
No.
Having a 3G SIM in your Jamin will make no difference. It simply does not have the hardware needed for 3G network.
EDGE is 2.5G (works with regular SIM) and unless your network supports it, you can not use it.
Just picked up a Hermes 8525 off of ebay.
While upgrading to the latest WM 6.1 roms available - I have been picking up the 3G network in my area here in Montreal.
I do not have a 3G sim card, and do not plan on using any of the data features either. I pretty much just use it as a regular phone - surf via wifi. Am I actually on the 3G network ??
I also do not have a 3G plan with Rogers. Is there any benefit to 3G if just being used as a regular wireless phone ??
If not being used for any data features, etc - will there be an additional charge applied ??
Should I just force the phone to GSM network only - instead of auto ??
Any feedback greatly appreciated
Have a good one
3G is data and voice. So, even if your not using the data plan your voice connection still auto connects to 3G network or Edge.
You wouldnt get charge for data as long as your 3G data connection is disabled.
You could force it to use a specific band (i.e. 850/1900 mhz) but you might have a bad connection on some areas since the phone auto connects to stronger signal. Hence better (sometimes) voice quality.
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
