Sprint/Nextel EVDO network hack

Does enyone know how to get onto the EVDO network from Sprint that would allow us to Direct connect with Nextel phones? I have heard that since sprint has come out with phones that utilize the EVDO network to access the Nextel network, people have ripped the software and successfully connected via other Networks.

The Kaiser is a GSM-based phone. There is no way to connect to CDMA/TDMA/EVDO networks with it.

sprint sells a phone called the mogul, or known on xda as the titan, you may wanna check in there...

Mr. NotATreoFan
hello
i thought that Evolution Data Optimized (EVDO) are same as High-Speed Data Protocol Access (HSDPA) but only with higher network speed? But my understanding was wrong. I tried to read difference but could not understand somethign at lay man term. can u please advice on difference.

EVDO is term used for non-GSM high speed data access. Sprint currently uses EVDO Rev A, for example. HSDPA/HSUPA only applies to GSM networks.

thanks for clarifications

Actually...
Not to be a smarty pants, but HSDPA is a form of WCDMA, a software enhancement of the original WCDMA that allows faster data transfer, and emphasizes sound and video transfers too. So, yes, the original post is correct in at least one part of the assumption, that Sprint's CDMA/EVDO network is similar technology. CDMA, and WCDMA are actually evolved from GSM, but, equipment wise, are wholly different deployments from each other. WCDMA was the first 3G technology to be deployed, in Europe and other parts of the world, primarily on the 2100 mhz band. AT&T's deployment of HSDPA (on the ever-so obscure 850mhz band) was the first in the world, but far from the first deployment of CDMA.
My understanding is that T-Mobile will be implementing their HSDPA service in something like 27 new markets here in the next few weeks, so some of us may have a second choice for high speed service.
Incidentally, Sprint, and Verizon's decision to go with plain-ol CDMA for their network deployments will, within the next 10 years or so, turn out to be one of the most financially expensive errors ever seen in the cellular industry, as it prevents them from upgrading and deploying the 4G tech that looks to be the next step for 90% of the planet...LTE. They can, and are, at least in Sprint's case, deploying a comparable tech to LTE called WiMax, however, it is not capable of the same speeds as LTE, at the top end, and will once again, push them into the land of obscurity. Sprint & Verizon are the only 2 major carriers in the world that chose CDMA for their standard when deploying their cellular networks. Losers.....

The T-Mobile 3G network is supposed to be live by December of this year, but it is running on the 1700MHz band which will eliminate almost all of the current 3G phones out in the US.
...and I hate Sprint and Verizon too.

T-Mobile 3G Los Angeles Oct. 23rd launch

So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!
http://support.t-mobile.com/knowbase/root/public/tm23715.htm#7
Sorry if this is old news, but i just realized it =)

this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...

you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...

That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

AWS?? well the tier 2 tech did say it...i dont know if he was just talking out of his ass or not...but we'll see in the coming weeks...ill try to get tmobile rep on the phone again to ask them how i can get it...or if i can, even though its supported..

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.

If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

Do you know who this user is? maybe i can PM him and get some details...i knew i wasn't going to get 3G with the diamond, but after talking to the rep. i kind of want to look into it more since there may be a possibility.

Honestly I'm gonna go ahead and call BS on him for that, I've never heard of anyone getting T-Mobile 3G and I know quite a few people with the Diamond/Raphael on T-Mobile in 3G areas.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

[INFO] Explanation of What 4G Really Is And Why The Vivid Thinks Everything's 4G!

OK, so it's come up in several threads, so I thought I might try and simplify things and answer some people's questions with a bit of a primer on GSM, HSPA, LTE, 3G, 4G, etc! So here goes! (And special thanks to ClippinWings, I liked the way you formatted this list, so I'm gonna borrow it! )
GSM Data Technologies:
So in order from slowest to fastest, the GSM data technologies are:
Legend:
Technology | Vivid Taskbar Icon | Standard Android Icon | Actual GSM Category
GSM | G | G | 2G
EDGE | E | E | 2G
UMTS | 4G | 3G | 3G
HSPA | 4G | H | 3G
HSPA+ | 4G | H+ | 3G*
LTE | 4GLTE | ? | 4G*
LTE-Advanced | N/A | ? | 4G
*3G/4G status here's disputed, I'll get to that later
The Vivid, displays G & E, then displays 4G for 3G, H & H+, then 4GLTE for LTE. So no matter what 3G network your on, it'll show 4G (because AT&T thinks H+ counts as 4G, more on this later), then when you're on an actual 4G network, it'll show 4GLTE.
Difference between Verizon & AT&T LTE phone radios:
AT&T's network is completely GSM based for 2G, 3G & 4G, whereas Verizon's 2G & 3G network is CDMA based. Therefore, one radio will work for everything in an AT&T LTE phone. This is different from Verizon, where the two different technologies necessitate two different radios: one for CDMA, one for LTE. This will most likely continue to be the way it works: Verizon (and eventually Sprint) phones will require two radios for two technologies, AT&T/T-Mo phones will only require one.
LTE networks are completely data focused and don't yet implement voice protocols. When they do, it will be VoIP based, so it'll just be more data (This will be called VoLTE for Voice over LTE).
This leads to one consequence, however, concerning simultaneous data & voice. Since this isn't implemented yet, phones must revert to the 2G/3G network to make voice calls. On Verizon, since they're two different radios, you can continue to use LTE data while using CDMA for voice (A new feature for Verizon, as CDMA networks don't handle simultaneous voice & data). On AT&T, they're the same radio, so dropping down to 3G drops the LTE connection. You can still use simultaneous voice & data (as you can on just about any GSM based network), but you just don't get LTE speeds.
Is HSPA+ Really 4G?
Easy answer? There is none. By ITU (the body that decides these things) original standards, 4G was any technology that could provide 100 Mbps downlink. By these standards, not even LTE qualifies. Only LTE-Advanced, the as of yet unimplemented successor to LTE, qualifies (Verizon, Sprint, & AT&T have all committed to LTE-A deployments starting in 2013). However, LTE being a new protocol that uses new frequency bands, it's natural to call it 4G. HSPA+ is an enhancement to 3G technology to provide a short term solution until LTE deployments are complete (mostly through enhancements to fiberoptic backhaul), and is very often called 3.9G (FYI, HSPA is commonly referred to as 3.5G). However, T-Mobile, since they didn't have an actual 4G deployment plan, started calling their HSPA+ deployment 4G. Especially since it gave speeds just as fast (or faster) than Verizon's LTE network, this caught on, and AT&T was forced to do the same to keep up. With HSPA+ squarely being called 4G in advertising, the ITU amended it's definition of 4G. It said that LTE, being fundamentally new, was clearly 4G. It also made a statement that, while not officially calling HSPA+ 4G, justified T-Mobile's & AT&T's use of the term. And since HSPA & HSPA+ are basically the same technology, the Vivid & Skyrocket just show 4G for it all!
I hope this helps clear up some confusion. I made every effort to ensure all of this info is backed up by research, but if I got something wrong, please let me know! Or if there's anything you think I missed that should be included here, please let me know that, too!

Now Asking the Second Part of the Question
Thanks for the expanded explanation. Now to the second part of the question:
Why do some people have great speeds and other people have poor speeds?
Here are some reasons I have tried to glean from the posts here. Please add, correct or clarify as needed.
1. LTE or lack thereof - Obviously only a few people have it now.
2. HSPA+ or lack thereof - The enhanced features of AT&T's 3G may not be in all places.
3. Bandwidth or lack thereof - I saw an article (sorry for no URL) noting that AT&T has more and better capacity in some cities than it does in others. This discrepancy between cities seems to be less of a problem for Verizon.
4. Load on the system - All those iPhones eating up what bandwidth there is.
5. Location - If you live in a hilly area like I do, there are going to be holes. Also, when I moved from a top floor office with a window to a 1st floor interior office (no, it was not a demotion), my phone service dropped.
6. AT&T System issues - Not sure what these might be, but a few posts have alluded to such.
7. Phone hardware and firmware - A couple of reviews I read noted that performance for the Vivid was somewhat less than other phones with the same or similar processor.

Great post!
and no worries, I just reformatted the list I got from your original post
(I totally would have forgot UMTS lol)
Teamwork!

From what I've read up, 4G qualifies for up to 56mps down (thats no load, perfect signal) and is just an upgrade to the Hspa+ protocol. I believe the reason AT&T doesn't show 3G, 3G+, and 4G as different symbols is because they believe it would 1. Confuse the mass population and 2. The mass population would be outraged wondering why if they have a 4G phone it was only picking up 3G (people not understanding the work and money involved in upgrading towers and such). I've heard people complaining about not ever picking up LTE around here and I just facepalm myself so hard considering Charlotte isn't supposed to get it till the 20th and even then we still wouldn't get it here out in bfe.
Good article though, I'm sure the clarification will help some of the newer people here.

all phones will probably end up using one radio after the next gen LTE phones come out: http://www.anandtech.com/show/5118/qualcomm-announces-a-bunch-of-krait-based-snapdragon-s4-socs
this includes CDMA-based phones.
also, the thunderbolt and rezound allow simultaneous voice and data when on 3G, i believe it's because of the way the radios are set up in those phones.
definitely a great post. it's too bad marketing took over the meaning of all the "4G" terms. thanks, t-mobile.

I hope someone makes a ROM that fixes the service bar so that it shows "3G", "H", "H+" and "LTE" properly. That's a total farce.

Most cooked Roms have it like that although I know on like winmo and wp7 there was regedit to do it.

This is a question for Canadian people or people that owns a Raider version:
Do you have actually seen the H+ icon when you are on a HSPA+ network?
Or is it just showing the H icon but you know you are on a HSPA+ network because of the speed?
This is because my network operator claims to be HSPA+ but I can't see the H+ icon only the H one.
My speed on speedtest app is about 6Mbps/3Mbps. Is this HSPA+ speed?
Thanks for your answers.
Cheers!!!

LG Thrill is same as LG Optimus 3D?

I have been posting in the optimus forum for help. I just noticed last night in a topic yesterday that LG Thrill and LG Optimus 3D are the same, except Thrill is 4G.
My phone is called LG Optimus 3D p925g, it's from rogers and I got it October 2011. It's 4G.
is mine the same as Thrill?
What happens if I use LG Optimus 3D 3G roms on a 4G?

Nothing happens. It's the same.

ok Thrill must be an american brand name or something.
when I flashed cyanogen mod ROM I remember seeing my 4G turn into 3G icon. Does it actually change to 3G or no?
also is this forum more active for help? I wonder why they have 2 forums if 4G/3G is only difference.

It's not even real 4G though. So it's all good.
The other difference is that the basebands are different.
One is international, the other is not.

not real 4G? What are you talking about.
I don't know what basebands are so okay.

Well if it says 4G, you're getting almost the same speed as 4G. There's a detailed explanation somewhere. I gotta find it.

Its 3.5g the way i have it my p925g. Always says 4g i dont know why even if i dont havr 4g speeds

4G implies 4th generation technology and standards. Ignoring the fact our '4G' is actually HSDPA+ (which is pretty much what 3G was supposed to be, but they did the same marketing BS with 3G)... we are nowhere close to the simple basic, no BS 4G standards of 100MBPS+ data speeds, with true multi-tower connections.
As well, all 4G means for most GSM carriers is that the phone has the HSPDA+ protocol enabled, and the towers in that region have the same... which is a simple software upgrade. You could be on a 500Kb connection, but they call it 4G simply because it has HSPDA+ protocol delivering those 2G speeds with a 3G technology.
The closest thing to true 4G on the market is LTE, which is totally new radio technology and tower technology, not simply a software upgrade that increases speedo's top speed from 5Mbps to 45Mbps, even though the motor is still only capable of 2Mbps.
The motor, btw, is the tower backhaul, and that is the real bottleneck in all of this and is what will determine your actual speeds. As it stands, there isn't enough hard line bandwidth out there to give true 4G speeds, and likely will be 5+ years before there is.
By then we will be on "6G" and some will still be running sub 1Mbps connections despite the hype.

ya we got lte phones hear now system isnt even up but rogers is claming its going to be 150mbps downloads

The Only difference
Thrill 4G Networks GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1900 / 2100
Optimus 3D networks GSM 850 / 900 / 1800 / 1900
HSDPA 900 / 1900 / 2100
HSDPA 850 / 1700 / 2100

maybe it is
HSDPA 900 / 1900 / 2100
OR
HSDPA 850 / 1700 / 2100
because 1700 / 2100 mean AWS and i don't think this phone (p925g) is aws

don't know what to do.
Hi,
someone offer me a Lg p925G from rogers which is unlocked. the problem: I live in france, when I put a french sim in the phone didn't find no network at all even a simple GSM; I tried to register manually to my network (the phone find it) but say that 's impossible to connect it. The phone is under the last V20C rom from rogers.
My question is simple: is that a hardware problem with the frequencies? or just a problem from the rom?
thanks a lot!

[Q] T mobile 3G/4G after unlock/debrand?

Hi All,
Is there *any* way I can get 3G/4G speeds on Samsung Focus S? I saw the unlock/debrand thread. Will it also enable 3G speeds on t-mobile network or is it hardware related and there is nothing we can do about it?

hardware...

My Focus S did 4G right out of the box.
The main reason you might not be able to get higher speed data lines is because of the frequencies your carrier uses to support those data feeds. Not all carriers are using the same bands. Rogers (here in Canada) uses the same bands as AT&T, so you pretty well have to wait until you can find an AT&T phone to buy to make it work.
T-Mobile in the US uses different bands, so their phones will only do E here in Canada. Likewise, and unlocked AT&T phone will only do E on T-Mobile in the US.

HOW THE F$%& do we get MMS to work if on Tmobile????

that is good

That is good? What are you talking about... @waswaser quit posting random **** to get enough posts to spam the threads! Anyways I finally got data for Tmobile and now I have MMS Woohoo! AT&T is refarming some towers so people with unlocked AT&T phones will get 3g/4g on Tmobile, that will start 2013 i believe...

"T-Mobile reiterates their wish to launch 4G HSPA+ in the 1900 band in a
large number of markets by the end of the year. Current testing shows a
33% increase in HSPA+ data speeds and improved in-building coverage.
“Rolling out 4G HSPA+ services in the 1900 MHz band will also offer
customers with the ability to use a broader range of devices"
in other words... Focus S should work @ HSPA+ by the end of the year (if you are in the right market. Which, selfishly, should include NYC)

You lucky son.... Anyways I get great reception where I life, but it's more of a rural town Northwest of SEATTLE. I've tried AT&T phones here and I get HSDPA+ so would I get it when Tmobile is done refarming? I'd be happy with 3g though as EDGE blows...

that is good
