3G

OK, I'm pretty sure I already know the answer, ie. "No", but I know so little about it I thought I'd ask.
is the XDAII compatable with the 3G networks beign rolled out? Here in NZ we're going 3G in the next couple of months, I assume GPRS etc. is all still supported, but I know if I buy a new device I'd like it to work with the highspeed network.

no xda2 is not a 3g phone

3g do you want a fry'd brain with that ?

3G in Australia/NZ is the "3" network from Hutchison which is basically UMTS so not compatible with the XDA which is GSM/GPRS
I noticed some people on eBay selling XDAs saying that they are 3G compatible but the smallprint read" on the 2G network" or something similar ie their fallback GSM network.
Cheers

if we are LUCKEY!
then maybe with software upgrades the xda
could be able to use
Edge also called G2,8
because it's based on G2 (GSM)
in maybe it dont need a new transmitter

EDGE is a new transmitter
UMTS (3G) is a new system even! So, forget the software thing.

3g problems

Hi. Newbie in this forum. Bought an htc tytn from u.s. but am from Phil using smart carrier with gsm band at 1800. after going thru sev topics, properly identified device as Herm200 rom:1.18.255.3 07/22/06 extrom:1.18.255.106 radio1.03.03.10 protocol32.34.7010.01H.
All phone features working perfectly except for 3G. Smart carrier people cannot help. What could be wrong. Vendor says 3g works on 2100 band. Confusing statement. What can be done? Connects to umts but when video call is pressed will not connect.

Which carrier are you on again? Smart Carrier? .. From what I know no carriers in the US support video calling .. Also, Cingular is the only GSM carrier in the US with 3G which runs on the 1900Mhz band ..
also .. what does your phone display while connected "G" or "U" ... what are your phone band settings .. can you also goto dslreports.com/mspeed and see what speeds are you getting ..

According to GSM world SMART (a Philippine operator) uses UMTS 2100, which your TyTN does definitely support.
Have you checked if your SIM card is 3G-enabled? Most 3G networks require special USIMs for 3G usage.
I just learned, that Cingular uses UMTS 850 and 1900 to be exact. According to the American HTC website the Cingular 8525 supports "Tri-band UMTS/HSDPA high speed wireless data network support (2100MHz and 850/1900 MHz), Quad-band GSM®/GPRS/EDGE worldphone".
Does anyone know if there is a special hardware version, that supports UMTS850 & 1900 or will my European TyTN work on those networks, too?

TyTN is tri-band UMTS .. 850/1900/2100 .. so it should work on these networks without any issues ...
And my bad .. didnt realize that you are trying to use the TyTN in Phillipines ..

You should also check, if the called party has a 3G signal, while you call him. Further make sure video calls are activated by your network operator.

3g problems in the philippines
Everything you guys mentioned in order(am in a 3g area calling a 3g enabled party with a 3g sim card). Even the tech staff behind Smart Communications cannot make it work. Displays U and u. But video call cannot push thru even if pic on front camera shows. There is 1 thin line( or command?) stopping it from connecting. My last option is to borrow my friend's unit and see if her unit's 3g works here then it's my device that's a problem. Thnks for the input. Keep it coming.

Hi. I don't know how they did it but Smart Communications did it! Apparently and ironically their 3g sim card is not compatible with the htc tytn but their regular sim is. Thanks all.

are u using 3G now in Phil ?
Is there a Globe perpaid 3G simcard ?

3g problems no more
Hi everyone. After my first thread i have finally got everything on my tytn working: 3g, mms, internet, phone. The problem was on the settings. Smart and Globe, the primary carriers in the Philippines can both work on the phone if the settings are right.

sectorlord,
yes there is 3g and hsdpa along with gsm and gprs and wap in the philippines. and yes you can buy globe prepaid 3g sim card.

glad to hear you've got your problems solved jjc!

ATT 3G settings with Topaz O2

Hello,
i've got a Germany Topaz with an original O2 Rom (6.5), and am currently in New York. I've inserted an ATT sim card, and the topaz came up asking whether it should install the ATT settings, which it then did.
I'm able to get a connection fine, but only with Edge, not 3G. The whole greater Manhattan area is 3G covered, so i should be getting a faster connection.
I'm wondering whether there is something i need to do to activate 3G? Anyone have any ideas why i can't get a 3G connection?
thanks.

Doesn't O2 Germany use 900MHz UMTS, not 850MHz & 1900MHz as AT&T? So your Topaz is likely not an 850MHz (& 1900 MHz) UMTS model - will be able to use only GSM.

Ok, thanks for that. But i thought the Topaz has the same frequencies as the Germany Kaiser, and i used that 2 years ago in California, with ATT, and had 3G almost always. Strange.

You are aware that there is a variety of models/frequencies specific to local markets?
What is the model shown under the battery: eg TOPA110 T5362?
Then do a search for that model and compare with the (UMTS/HSDPA, not GSM) specs for AT&T Pure:

[q] what's wcdma,cdma ? Are they the same ?

Hi , my phone has WCDMA along with GSM (XPERIA X1) but can't read a regular CDMA simcard !
I asked the network service but didn't get much help .
So is WCDMA really CDMA ? or is it a name for UMTS ?

WCDMA is an alias for UMTS.

But whatever you call it, it still uses the technology named "Code division multiple access", right ?
And a device supporting what is called WCDMA/UMTS only (and NOT what is called CDMA), will not speak to CDMA only cell sites.
Get's confusing when names are used in different contexts.

WCDMA is just a technology used in many networks, but it is used synonymously for the UMTS family (3GPP) as it is one of the core technologies in that 3g network technology.
CDMA is also just a technology used in even more networks, but may be falsely used synonymously for CDMA2000 (3GPP2) which is the technical name for the 3g networks used in the US for example.
Here are some Wikipedia Articles that should shed some light into the whole terms:
3GPP: http://en.wikipedia.org/wiki/3GPP (That are the people behind UMTS)
3GPP2: http://en.wikipedia.org/wiki/3rd_Generation_Partnership_Project_2 (That are the people behind the concurrinng technology used in the U.S.)
CDMA: http://en.wikipedia.org/wiki/Code_division_multiple_access (A networking technology not only used in mobile systems, but also in GPS for example)
W-CDMA: http://en.wikipedia.org/wiki/W-CDMA_(UMTS) (1.: Air interface most commonly used in UMTS Networks based on CDMA 2.: WRONGLY used synonymously for UMTS)
CDMA2000: http://en.wikipedia.org/wiki/CDMA2000 (Has two meanings: 1.: Air interface "CDMA2000 1X" that is the concurring technology to wcdma but serves the same purpose 2.: Family Name of Network Protocols also known as US-3G ### Here the synonymous usage for Air interface and Protocol family is ok as they are really named the same ###)
UMTS: http://en.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System (Family Name of Network Protocols that uses WCDMA as an Air Interface and is commonly found as the 3G Network in Europe and Asia)
The post-3g mobile networks will use a single technology as the 3GPP2 companies stopped development of their own 4G standard in favor of LTE (a post-3g and not really 4g standard) and LTE Advanced (which will fully comply with the 4G definition).
Where LTE (Advanced) is based on the UMTS technology by the 3GPP People.
LTE: http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution (Post-3g / Pre-4g network based on UMTS)
LTE Advanced: http://en.wikipedia.org/wiki/LTE_Advanced (The "real" 4G network)
4G: http://en.wikipedia.org/wiki/4G (4th generation wireless cellular standard that is currently in the make)

CDMA is just a theoretical type of air interface... how the physical layer and data link layer work. I wouldn't expect all CDMA to be created equal. Not sure how Verizon got to the point where it became synonymous with CDMA, because lots of carriers use the technology. Each implementation varies quite a bit in terms of spectrum allocation, time division and things like that.

[Q] Verizon Trophy AWS or just PCS?

Does anyone know if the Verizon Trophy will do CDMA on AWS with the correct PRL on any of the available radio software?
Also is there a app or a way to show cdma call info such as channel, PN, rssi?

It says "HSPA:AWS 2100" and that is the GSM Trophy. I think its safe to assume that the Verizon model supports it as well + CDMA.. but.. well.. AWS is new one on me. I won't pretend to fully understand what your talking about. XD *haha* I better go do some reading.

AWS is advanced wireless services. It's the FCC name for the band of spectrum the 1700 and 2100mhz range.
What I'm not really sure about is if the same radio is used for both CDMA and HSPA. The phone can do AWS if using HSPA, but it uses the cellular and PCS bands for CDMA. (800 and 1900mhz)
The issue is that the radio need to be programmed for those bands and there is hardware needed to make it happen. So a phone programmed for 800mhz can't just switch to 2100mhz unless there is hardware present.
The Verizon version of the phone might just have an extra radio thrown into the case that operates seperatly from the GSM one. If that is the case then it wouldn't be possible to use CDMA on that frequency. If it's all tied into the same radio then it seems like it could be done in software. In either case I'm not sure if will ever happen because you'd probably need to write your own firmware to do so. (It really wouldn't make sense for HTC to waste time seeing if the phone would do CDMA on 2100 if it wasn't designed to)
For reference there is a great article covering the bands here:
http://www.phonescoop.com/articles/article.php?a=99
There is also the full version of the spectrum chart online here: http://www.ntia.doc.gov/files/ntia/publications/2003-allochrt.pdf
There is a dev screen you can get to on the phone to show signal strength and a few other options. If you dial ##634# you can select field trial. You can see Channel #, band class, Active Set Pilot PN, Rx Signal Strengh, Rx Power (dbm) under the EVDO screen. There is also a section for 1x and GPS. I'm not sure if another option shows up for HSPA if the phone is on GSM...
EDIT: The best I can tell is that AWS uses UMTS/WCDMA so the phone should support that. HSPDA is just a faster version of WCDMA so since the phone can do HSPDA on 2100mhz it would be able to slow down to WCDMA speeds. The only time I could see it possibly being an issue is if CDMA was being used on 2100mhz and not UMTS.

Only thing I am seeing inside of the newest Verizon Trophy software (mango v3 8107) is that they added support for CMAS.
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\ShortMsg\Settings]
"CmasOperatorEnabled"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\ShortMsg\Settings]
"CMASAlertOption"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\SMS\Broadcast]
"TestPort"=dword:4370
As for radio, there is only one radio software.. but from what I can tell, the CPU/radio has all the same support as the Trophy GSM, but with the added CDMA. AWS should work, but only via GSM bands.
