Frequncies on phones - Networking

Hi all,
Sorry if this sounds daft, but I have just been given the tech assult by a Telstra Australia guy.
Telstra uses a "Next G" network that used 850MHz and will state that ONLY phones bought through them will be able to fully utilise the network. Is this a firmware thing (IE, can I flash the radio rom) or a hardware thing? If I bought a device from anywhere else would I be able to utilise the speed of the "Next G" network? If not, what features would we be missing?
Cheers
Al

Frequncies is a hardware thing
some phones support that band as it's also used in usa you can check the wiki for the phone in question

if you have a quad band phone with 850 MHz, it should work ontelestra, the only features that might not work on it are features that have been cooked into the rom. Phone and generic features will work as the are standard to all hardware types.
If your phone is 3g capable, yes you will be able to use their updated 3g as the attachment to allow their network to work on your phone will be on a telstra sim card.

3G/UMTS Issue

I just bought a HTC Dual Touch, traded in a Cingular 8525. But I cannot get the DT to detect the 3G network that my 8525 did. So right now I can only use the edge network (slower) and this phone is supposed to be twice as faster as the 8525. Any thoughts ???
um... hv u consulted ur phone network service provider?
3G/UMTS
Yes I pay the extra fee for internet use with my internet user, and was activated on my Cingular 8525. I dont know why my dual touch doesn't detect the 3G network
can't they provide you with settings parameters, such as access entry point and etc, so that you can add a new connection manually?
I've also noticed this in moving from my tytn to my touch dual. I tested with them sitting side by side and identical settings. It'd be nice if it was just a problem with software or settings, but I figured it was the move from a quad-band phone to a tri-band one, and that the 3G stuff runs over the one I lost (850Mhz).
the 8525 is quad band gprs, tri band UMTS/HSDPA
Touch dual it tri band gprs, single band UMTS/HSDPA

Also, looks like the TyTN II is the only HTC device which has 850/1900/2100 UMTS bands. All other latest models (Touch, Touch Dual, Touch Enhanced, Cruise, S730, etc) has only 2100.
I dont know where you are but where I live cingular/AT&T uses the 850 band.
experiencing same problem and the reason is the dual is configured at 2100mhz waiting for a radio fix or something to help us go down to 850 as well.
from what i've heard there is a version touch dual 850 which works on the 850mhz band, if we can get the radio from that model maybe it can help our situation.
ok so australia is on a 850mhz network and telstra has the touch dual working on there 3g, do you guys think if we load the australia rom it would work or would we probably need the radio as well?
how would you find out if you have that different version?
i've been checking telstra's web page for specs but they match up exactly so maybe its just a radio change.?
Did anyone ever find out if a radio update to the original Touch Dual would allow quad band support and 3G bands for US frequencies?

Does anyone knows how to download Australia rom on touch dual
I have the same problem, I have a 20 key dual and can't use it. Works great in Indiana but, when I'm at home in Ohio it's dead I think the towers around my home are on the old network. I can only use the quad band phones. Bought a Cruise and works fine other than the Dual is just so sexy I hate not using it.
i have the u.s. version of the dual distributed by Best Buy, my problem is that it doesn't show the H logo for HSDPA in places where my AT&T Tilt always did, and I do have HSDPA enabled on the Dual.

Samsung Omnia i900 - unlocking UMTS frequencies

Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.
I just got an Omnia and sometimes it hits the 3g network so i am sure that the firmware is there but it is locked.

more details please - where are you at? what network/carrier do you mean? do you really see 3G icon and experience fast browsing/download? what is the firmware version on your Omnia? (Settings -> System ->Version)
AT&T.I have it from Singapore.PDA:i900DXHH3/DZHH3.As i mentioned it hits 3g for a minute or so and then it goes back to edge
man i sure hope this issue gets fixed!

a US model for the Samsung Omnia is coming to the US in October via AT&T. Look for the Samsung Mirage.

AllTheWay I started this thread to solve the problem for people in US,who already have Singapore/European Omnia, the i900. It's a well known fact Mirage hits AT&T on October 21st, but it doesn't help us one bit. Unless of course, you're willing to dump the ROM from i907, reverse it and replace the i900's radio with the one from i907 with all supported UMTS frequencies unlocked
I wish somebody could help us out on this issue, I dont know enough about rom editing to be of use ;(
besides, i think the 907 is already available but not branded to at&t: http://www.celluloco.com/samsung-i907-omnia-8gb-us-3g-support-version-hsdpa850-1900-e-pr-1873.html
any update of this thread?
HTC Diamond users with US 3G - please help
I'm starting to believe it might actually be possible to tweak existing radio firmware to unlock UMTS 850/1900Mhz bands using already embedded secret debug menu from Samsung developers, rather than having to dump it, reverse it, patch and flash back. Here is the secret code to access Root Debug Menu on Omnia: *#197328640#
Option #4 "UMTS rf nv" has sub-option "umts rf nv write", which I think allows to modify the active UMTS bands in the radio. Assuming we have that set correctly, option #9 "Common" from the same Root Debug Menu has sub-option #5 "WCDMA Set Channel", which allows to specify downlink channel range.
Here is my idea: some devices, such as HTC Diamond with US 3G enabled radio, have the same Qualcomm chip as Omnia, and run the same WM 6.1 OS. So,
I'm thinking it's worth a shot if someone with US enabled HTC Diamond provided us with settings from his device for those 2 configurable menus I just mentioned. If you backup your own settings, so you could restore them if it doesn't work - I think trying settings from another device will not fry the radio, worst case scenario transceiver will just shut down and be offline until settings are restored.
This would be great.... Iv'e been dieing to get 3g in the usa with the omnia.... Can anyone help with this?
Any updates on this? Would be nice. Especially now since we know omnia isn't coming to ATT as i907
If possible i will donate to the guy that dicover how to enable!
It may be easier to copy the setting from an I907 Epix. That has almost identical hardware and it is ATT + Samsung + Tri Band UMTS.
When I try writing the WCDMA channel it says "That value is wrong".
Also, I can only set one number, so I assume that they want me to set one in the listed range which is WCDMA2100.
Here are the bands:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
Oddly, the Channels currently set stretch a few beyond the range cited on Wiki for WCDMA 2100. They start on the same channel.
Another oddity is that there is no uplink channel. I suppose that people just use Edge for this? Does the I907 do HSUPA?
well...
i'm living in ISRAEL,
and we have GSM network but we also have another cellular company that work with "UMTS 2100/850" band..
i'm working well on 3G with the 2100 band (my onmina have only UMTS/WCDMA 2100 only without 850 also..)
i will be happy to open if it's possible the UMTS/WCDMA 850 also.. so i'll have both 2100 + 850 on WCDM/UMTS (not GSM) freq...
but i'm not shure it's possible to open what ever you like.. anyway i'll try to ask our guys (at my cellular company i'm working at) about this freq stuff...
hope this thread will bring us good information..
also, just know.. my job is with Cellular phones.. and we have "for Testing" Omnia phone with WCDMA/UMTS 2100/850 bands..
but i don't know how i can download the firmware to my pc and try to use it on my omnia back...
if anyone know how i can "take-out" the firmware explane to me and i'll try to do it....
..
Someone else has further evidence:
http://www.modaco.com/content/i900-...6374/open-omnia-umts-wcdma-850-900-1900-2100/
OK guys,
i had this omnia in my hands..
the Version says
PDA: i900LJJHK1/JJHK1
PHONE: i900LJJHK1
as i think.. it's diffrent model.. I900L this "L" model.. not like ours phones... (i think, it's looks exactly the same!)
i don't think the ROM will chane the bands anyway..
anyway as you asked me to do.. when i'm doing the *#2263# code
i'm getting diffrent menu then our Omnias..
i'm getting 3 options that one of them it's "WCDMA Band Select" and in there you have ALL the UMTS bands and there is "Automatic" option.. what says this phone open to all kind of UMTS networks............ (including GSM also..)

jakeordie said:
juvaknin, you posted this on Modaco as "PHONE: i900JJHK1" without the L. Please let us know which one it was. Thanks!
Click to expand...

yes, it was suppose to be with "L" mabe i forgot it on Modaco forum
anyway i hope this is only Rom issue... but anyway i can't "Rip" the rom right now.. because this phone is 24/7 testing time and i can't "make it gone" from the test station to drop the rom to my PC
i hope there are more guys who have this I900L to share the rom with us..
anyway you remmeber the code that you can change the phone settings buy country?
the main code is (type it from the dailer) *#1546792*#
and the password for section "2 - Preconfiguration" is *#81230*#
it's looks like if we will have the code for the "Internal" section, mabe we will find something in there ?!?!
if we will change to another country.. like Austrlia or something.. the bands will change also? what you guys think?
Hi juvaknin I was reading on web that this i900L is for latinamerica and its frequency was
Cellularhone
Cellular_Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900
Cellular-Data;Links: CSD, GPRS, EDGE, UMTS, HSDPA
found this at hxxp://www.pdadb.net/index.php?m=specs&id=1446
change the xx for tt. Also wher did you buy this phone this info is real ?

Band restriction hardware or software?

I live in southern africa where its still going to be some time before the G1 is launched.
It would be possible for me to order the US G1 from ebay but I am concerned about the network band because firstly I want to know that the phone will at least work on the regular 2G network (1800 in my country) for the usual phone calls and then of course I want to be able use 3G for Internet access. I don't know the 3G frequency in my country but the service has been available for over a year already.
Is it a software restriction which can be resolved by updating the firmware at a later stage or is there actually different hardware for the model being released in the US and those being released in other countries like the UK?
Thanks!
Take a look here to find the UMTS frequency that your carrier uses (of course, call to double check):
http://en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
It hasn't exactly been confirmed yet, but the G1 is supposed to support both 1700+2100 (UMTS IV) and 2100 (UMTS I) networks. Since African carriers are all using 2100, you should have no problems getting a 3G signal without having to worry about hardware/software compatability. You should also confirm that your carrier will provide the approrpiate connection settings in case you need to set it up manually.
The G1 also comes with quad-band GSM/EDGE, so you will certainly be able to receive 2G signals.
However, keep in mind that the first batch of G1s will be locked to T-mobile. You will need to make sure that you get a carrier-unlocked device in order to use your carrier's SIM.

Thanks, that makes me feel more comfortable with ordering a G1 from the US.
I was just concerned because I read somewhere that the US version does not work in AUS so there obviously are problems in some countries with the bands. The UK version will apparently work in Aus.
Again, I want to emphasize that you need to make sure you have an unlocked version. When you first turn on the phone, you are required to log into gmail (or create a new account) over a 2G/3G network. If you are unable to login (because the phone has not been unlocked to work on your carrier's 2G/3G), you will not be able to use the G1 for anything other than emergency calls. You won't even be able to enable WiFi to handle the login.
http://androidcentral.com/g1-wont-work-without-a-data-plan-period/
If at all possible, I would advise waiting at least until some other folks have tried bringing the G1 to other networks so that you know what exactly you will have to do to get one working on your carrier.
Thanks again, I will definitely ensure that I do not purchase a network locked G1.

3g compatibility

Hey guys, I'm interested in purchasing this phone. Only thing I'm wondering about is the 3g compatibility in North America, specifically on Rogers Wireless in Canada. I know it is not compatible out of the box but wondering if one is able to make it compatible. May sound like a stupid question but I'm unaware on our it works. Thought since there are many ROM updates that it can change the 3g frequency. Thanks in adavnce.
If it doesn't work out of the box, it's not gonna work. The frequencies are hardware specific, so no ROM change would make it work. I'm not familiar with your carrier, but look up its 3g frequencies and then check if they match with those of the HD. (make sure to check the Australian HD as well, as it has slightly different frequencies and can work on AT&T in the US, while the normal HD cannot)
if Rogers is on the 850 3G band, then the Telstra Touch HD should work. i have the Telstra HD and it works on at&t's 850 3G network. unfortuantely, you WILL NOT be able to change 3G bands with ROM updates.
So if I were to obtain the Telstra HD, I am still able to update the ROM on the phone correct? That would be awesome news if the Telstra HD works on our Rogers network. Has anyone in Canada tried it? If so were can I obtain a Telstra HD that will ship to Canada? Thanks for the help guys
Hi,
I have the Touch HD (T8282 so not Telstra which is T8285) in Canada on Fido (which is owned by Rogers and works on the same network) and it works perfectly, however only on the EDGE network for my data plan. I have to say that it is still pretty fast and I dont suffer from not having 3G that much.
I would actually recommend changing the ROM (I have Dutty but I tried L26 too), since it will then come with a Network Wizard that will automatically detect the network and configure your phone automatically ( as opposed to doing it manually with a standard ROM).
Hope this helps,

[Q] Radio Question - I couldn't figure out yet

Hello,
I have been reading about HTC Vision Radio around posts here (For both the G2 and the D-Z).
I saw that that the hardware specs for the Radio bands are different between the 2 models and that people can actually flash the Radios from both models into the G2 device (Which I own).
Considering I use an Israeli operator that has 3G network only (known that its bands are 850/2100 here), My question is - Does updating the Radio for my device is actually controlling the bands I can use with it ???
In other words, The main Radio circuit supports all bands and then the Radio Firmware locks it to use the specific band for the specific operator ? (i.e. T-Mobile) ...
I would love to know if that's true, so I definitely need to upgrade/update to a working Radio for my operator since I know right now I'm using only the 2100 Band and I'm getting real reception issues.....
Thanks in advanced,
Amir.
You're asking whether changing radios can change the bands used by the device for calling/data? If so than no it can't, flashing a different radio can't change a Tmo G2 to use at&t 3g bands etc... That's pure hardware.
Sent from my T-Mobile G2
