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.

..May be why Sprint is now selling off all it's towers to TowerCo

Question about HSPA.

Trying to get my head around all the GSM acronyms.
Looks like AT&T rolled out higher speed 3G in my area HSPA 7.2.
Does My captivate support it, and is there anything I need to do to use it?

****DOH MODS PLEASE MOVE TO Q&A****** Sorry.

i believe att prevents you from accessing it leaving it only for the iphone how can get the faster dl speeds

HMMM false advertising on Amazon's part perhaps?
The super-smart Samsung Captivate for AT&T brings a fully integrated entertainment, messaging and social networking experience to your mobile phone, thanks to its open and innovative Android 2.1 platform. You'll be able to zip through the Web and multitask between a bevy of apps with the Captivate's 1 GHz processor and ultra-fast 7.2 Mbps 3G connectivity.

I just called AT&T and the HSPA 7.2 isn't on my closest tower yet, the CSR told me that my phone would get it as soon as it is completely rolled out.

The thing to understand about HSPA is, while the radio on the phone and tower support 7.2Mbps down, there may not be enough backhaul (wired or microwave connection) to AT&T's network to provide you a full 7.2Mbps. For instance, Charlotte, NC was one of the first cities to gain 7.2Mbps. I've been there multiple times, but the highest I have seen was close to 3Mbps.

Thanks for that info. AT&T has been busting their ass on infrastructure here. Uverse has rolled out and then we have the 7.2 roll out.

4G on HTC HD7?

The rep told me that is is 4G capable, if it is now or will be, I have not heard anything about it or seen a 4G signal icon, only 3G. I have t-mobile in Florida FYI.

It's not 4G capable. I believe it can go up to 7.2Mbps, still plenty for most users.

is he/she a amazon rep , cause they said me that hd7 supports 4G and also they are hooking up all customers with 4G 200 mb plan with tmobile , even though i didn't believe that , but i asked couple of times to amazon woreless and their reps repeatedly insisted that hd7 has $G , thats strange. They are doing pathetic false advertising ; This is what they are saying exactly.......
T-Mobile's New, Expanding Super-Fast HSPA+ Network
As of June, 2010, T-Mobile has upgraded its traditional 3G network to HSPA+ in 25 major metropolitan areas across the U.S., and it plans to continue rolling out this network upgrade to over 100 metropolitan cities and up to 185 million people by the end of 2010. HSPA+ provides our fastest data speeds, up to 3 times faster than AT&T and Verizon's standard 3G networks, while allowing simultaneous voice and data capabilities for the ultimate wireless voice and data experience.
HSPA+ enabled areas will enjoy 4G-like speeds, with a theoretical capability of up to 21 Mbps peak download speeds (and typical download speeds averaging between 5 and 8 Mbps).
While this 3G-enabled mobile phone doesn't offer HSPA+ compatibility, it can benefit from enhanced speeds when connecting to the HSPA+ network today.
can anyone explain what does that mean?

It means up to 14Mb/s as compared to the normal 3G speed of around 3.5Mb/s. HSDPA+ goes up to 21.1Mb/s and HSDPA, which is what the HD2 and now the HD7 use, is basically considered to be 3.5G and rated up to 14Mb/s.

now i got it , didn't understand why amazon folk were stressing that it supports 4G , this explains why tmobile tv is running like a trash on present 3G so once hspa+ is on 3g speeds too increase. thank you.

Actually, T-Mobile's 3.5G (HSDPA) is faster than Sprint's official 4G. TV should run perfectly fine on T-Mobile's super fast 3.5G.

T-Mobile TV's bad performance is only on the WP7 and hopefully Microsoft will fix that just like they need to fix youtube quality. I have the Vibrant as well and T-Mobile TV works fine on the 3G. At least on my HD7, Netflix has much better quality than Youtube and T-Mobile TV.

This article I found will clear the air on most of the misunderstanding of 4g capability. Google (CNET WILL THE REAL 4G PLEASE STAND UP) BTW I run Netflix on my HD7 flawlessly, and that is on numerous trips around Houston.. I <3 my HD7...
Sorry about not being able to post the actual link.. I'm a new user and can't post links..

I agree, netflix looks really good, especially when im on 3g. When im off 3g its acceptable. I do to love my HD7

So, why call it 4g then? I guess they just put it out there because it is a good marketing technique? Saying your first and the only one with something has a pretty big affect, especially on the people who want the first and best of ANYTHING and EVERYTHING no matter the cost.

Great article, but it does not elaborate on the HD7 or any WP7 specifically, just carriers.

[q] tmobile 4g

First, I'm a flashing newbie, and still have the stock ROM and Radio flashed on my Touch Pro 2.
TMOBILE has now updated(via some secret behind the scenes update) their Touch Pro 2 owners to "4G" coverage in the Detroit metro area. I would like flash to some of the ROMS offered but I'm not sure if after doing so will I continue to receive TMOBILE'S 4G coverage. I understand that "radio" flashing is separate from Rom flashing but is anyone sure that just flashing the ROM would not effect the TMOBILE 4G update.
Any help or insight is greatly appreciated.
Thanks

Does the TP2 hardware even support 4G? That's not something you can just "upgrade". Are you sure that they're not just offering more bandwidth via HDSPA? If that's the case, then what ROM you're using will have no effect on that seeing as nearly all custom ROMs have it on by default.

Got a screenshot of your TP2 showing 4G?

from my understanding, only the touch pro 2 from europe and japan have the 4g hardware, usa only 3g hardware, thats why i bought mine from taiwan so when 4g comes out, im well equipped!!!

T-mobile doesn't have 4G coverage in the US...despite their claims.

what they are actually doing is claiming their 3g network as 4g. its hspa. they took a card from verizon that considered their 2g network to be 3g. "you mean, alot of our 3g network is slower than atts 2g? and the only bits that are fast enough to keep up have less coverage than their 3g and is still slower? nonsense! i choose not to believe!"

T-mobile is marketing the same network even when they say 3G or 4G because it's all just upgrades, the appropriate term should be "3.5G". all of their sales reps i've encountered don't know anything about their network or their devices.
a week before the G2 came out, one of the reps tried to tell me that it was sporting a "dual-core processor". i laughed and corrected him without missing a beat. just watch their commercials...it's sad to see someone advertise 4G when it's just "3.5G".

Actually, it's HSPA+, not HSPA, T-Mobile & Sprint are advertising as 4G, which is faster & only a select few devices support the new HSPA+ speeds. So, it's more like 3.75G. HSPA+ provides HSPA data rates up to 56 Mbit/s down and 22 Mbit/s up. Future revisions of HSPA+ support up to 168 Mbit/s using multiple carriers. Regular HSPA maxes out @ 14 Mbit/s. The TP2 & most of HTC's 3G/HSPA(+) devices only support 7.2 Mbit/s down, 2 Mbit/s up. So, to answer the OP ?, If the network in that area was slower than 7.2 Mbit/s down before the upgrade, you will see an increase, but it'd be maxed out at 7.2 Mbit/s due to device limitations. As this is a Hardware issue, ROM doesn't matter other than the fact the lighter ROM's runs faster & therefore can get higher speeds because of the extra free RAM/Resources. Whereas, heavy, more feature rich ROM will tax the device more & therefore the CPU/RAM/Etc. won't be able to attain max bandwidth. It's like having a 30 Mbit Cable/DSL connection on a Pentium 3 PC. It'd never get the max speed as the system is just too slow to take advantage of it.
So basically, their advertising maybe false, it is used to explain a faster network & used to simplify which devices support this new speed. Most consumers wouldn't understand all this. So instead of dealing with, "why doesn't my 3G phone get full speed? *cry*" from customers not understanding their device has a limited bandwidth. Think of it like the days of dial-up modems. ISP A has a 56K network, but User B has a 28K Modem, so User B only gets 28K speeds.
"A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as ultra-broadband (giga-bit speed such as 1000+ Mbit/s) Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users."

So it goes something like this;
2G -> EDGE (2.5G) -> 3G -> HSPA (3.5G) -> HSPA+ (3.75G?) -> 4G (?)
Also keep in mind it's measured in bits per second, not bytes. There's 8 bits per byte. So 8Mbit/s = 1 MB. Also some service providers cheat by counting it as 10 bits per byte. (b=bit/B=Byte)
EDIT: Interesting side note, according to gsmarena.com, the G2 & MyTouch 4G only supports HSPA 14.4 Mbit/s down & 5.76 Mbit/s up (T-Mobile's network is 21 Mbit/s according to reports) & the Evo 4G only supports Rev. A, up to 3.1 Mbit/s.

[Q] 3g/4g confusion

I have a Galaxy S (i9000t) from Bermuda, and am not happy with my service provider, so I'm looking at switching over to another provider who also sell the Galaxy S i9000t. They just launched 4G service today, and in their list of 4g supported phones they have the SGS. Is this true? I dont understand much on the differences, but they are saying you don't need a new 4G phone, that current phones are compatible. Instore they have the iphone4 and the SGS listed as compatible 4G. Can someone please explain?
http://www.cellularone.bm/4G.asp

The "4G"* that CellularOne are advertising is HSPA+. The Galaxy S I9000 is capable of HSDPA up to 7.2Mbps, but does not have HSPA+ as standard (though T-Mobile US have announced a HSPA+ version for their own network). If the network offers 7.2Mbps HSDPA as well, like T-Mobile US, then you'll still see pretty good speeds from the I9000, but an HSPA+ phone could theoretically download a lot faster on a suitable network.
(* Arguably no current "4G" networks are officially 4G according to the ITU, who decide such things. However, this battle is lost now that so many networks have decided to start using that nomenclature, and even the ITU have been forced to concede that the term may be used to forerunners of true 4G technologies.)

thanks heaps. I appreciate it. I emailed Cellular One today, and interestingly enough, their official response was "the Galaxy S is a 4G phone, you will be able to use that"

Never confuse marketing (which includes what a salesperson tells you) with the truth.
But yeah, the term "4G" seems to have escaped from formal standards, and is basically meaningless.
