[Q] Can I use Tmobile HSPA+ Network

I just noticed yesterday that T-mobile has a 4G network in my area and I was wondering if there was a way to force roam 4G on tmobiles network? So that I could pick up 4G.
If its possible how?
Oh and sprint needs to hurry up and put 4g everywhere

You said it yourself. T-Mobile is HSPA+, Sprint 4G is WiMax. So, no.

Naa dude. HSPA+ is not compatible with cdma(sprint). Matter of fact t-mobile is using 4G now because its "trendy" and everybody else is using it. Their network is closer to 3G in infrastructure. But thats up for debate.

That sucks like hell. There's 4G here I just can't have it. AHHHHHHH!!!
Well if its like 3G I guess I'm not missing much.

You are on the money. HSPA+ is no more than an upgrade to existing 3G technology. If I remember right, it only has a theoretical max of 54 Mbps down. It is not, nor will it ever be, 4G.
Granted, the current 802.16e standard of WiMax is not 4G either...just waiting for that 802.16m standard to be finalized =). Which once that is complete, infrastructure can be updated and we should be able to utilize it with a simple firmware update.

No its way faster than your normal 3G. Faster than WIMAX too. Its nothing to pull down 7 or 8 Mb.

I bet it's better on battery than wimax is on ours.

It uses the same radio for voice. The EVO has a separate 4G radio thats has to be activated and scan then connect. So 2 radios running at the same time would use more battery than 1 GSM radio running. Also CDMA has a tendency to use more battery when searching for signal in low signal areas.

Having installed T-mobiles 3g upgrade here in Chicago market back in 2008, I can say definitively that HSPA is just a radio cabinet addition to the existing cellular framework. Depending on the layout of the tower/site, "Flex radios" handle the data on 1, or sometimes more antennae, while the voice travels over GSM through remaining antennae. Very similar to ATT infrastructure, but tiny radios handling big bandwidth.
Having said all that, 4G is a silly buzzword that Sprint started, and T-mobile is now exploiting.
In a way, Sprint is just using extra radios on top of their existing 3G cellular, and just integrating the enhanced data speeds of Clearwire's network into their own.
T-mobile's speeds are indeed fast both HSPA and HSPA+, but to call them 4g may be overstating it, as it is just an upgrade to their existing technology, and not a new technology.
As another poster stated, nobody officially has 4g yet, not even Sprint, and until the 802.16 commission finalizes and LTE is launched we still won't.
To re-emphasize to the OP, not a chance, and don't believe the hype.

I can see sprint(or clear) and T-mobile going to bed for some real 4G'ness.

Yeah, I heard a rumor that Sprint may eventually adopt LTE.... It makes sense.
Wimax will make a great backhaul, and could stay in place, not to mention supporting cities and rural areas. But LTE will be the big daddy, and similar to WiMax, works on it's own and should be seamlessly integrated on top of cellular.
I'm not sure but I think it can work with CDMA or GSM, hooray for global WiFi!

I wouldn't count on LTE on Sprint just yet. Hesse denounced it last week; however, Sprint, Clearwire, Google, Time-Warner, and a couple others purchased Spectrum not only in the 2.5 GHz, but the 2.3 GHz band also. So the bandwidth is there and, in the past, Hesse has been quoted saying they can easily switch to LTE if need be.

Thanks for the info.
I think the most important thing in the article is that LTE can happen if necessary.
Sorry for getting off topic.

A theoretical Sprint to Verizon LTE question

So I love my Evo 4g, but I've grown to hate Sprint. I know that it is possible to port my existing phone over to Verizon's service (using the alltel method), but I'm also looking at that sexxy new Evo LTE.
Given that Verizon already has an LTE network, would it be possible to access their LTE network on a Verizon Pre-paid plan?
I realize that no one will actually be able to verify this until the Evo LTE ships, but in theory would it be possible? I'm not sure if the two LTE networks operate on different bands from one another.

Hmm, looks like it will be a 'No'. Taken from a CNET column
...AT&T and Verizon are using 700 MHz spectrum, while Sprint is using 1900 MHz and some 800 MHz spectrum. That's why those networks are incompatible, even though the underlying technology is the same...

Also, the EVO 4G LTE might be held back in the U.S. due to a patent war with Apple. All over how it interprets contact info in a body of text.

Wasnt this already cleared up? I thought i read that the ITC approved the HTC EVO 4G LTE and the HTC One X late last week.

no 4G?

hi
i recently got a nexus from google.
it woks like a charm but i notice i have never gotten 4G on my phone.
i know there is cus my friend has 4G on his GS2.
so any one knows why is my phone not connecting to 4G network?
any help will be appreciated
PS: the APN i have is epc.tmo.com

It wasn't built to display HSPA+ as 4G for T-Mobile.
Google and rest of Europe considered it plain old 3G.
HSPA+ is not true 4G. It's considered 4G because it's almost as fast as 4G but it's not and people don't mind being tricked by that. They want to feel good about their phone. So they simply accept it.
I would just to brag about it. =p
Look at the AT&T 4S, it has HSPA+ but they don't advertise it as 4G. They just say it's faster then normal 3G.
That's why all my friends on AT&T with a 4S and jailbroken just get winter board and change the 3G to 4G and say they got 4G.
It's as fast so they say, "WTH!!! Let's make people feel like they got 4G and see a symbol that says so, even though they know they don't."
That is why you dont see 4G.

Ahh ok. Im asking cus someone told me i needed a new sim card. But thanks

Yeah I understand why you would be confused. U assume it's 4G since it's as fast. =p
I'd do the same unless I'm told. And since I found out when the 4S came out (I was confused at first), I learned it's just simple 3G on steroids.

Actually one of the firmware updates to the 4S revised the indicator so now it *does* say 4G on AT&T. Which is frustrating because non-technical types now say things like "Well my son didn't get 4G on his Verizon 4G phone in our area, but I get 4G on my AT&T iPhone, so I guess AT&T has better 4G."

I know.
Advertising something that is not true. They can trick people into thinking that the AT&T 4S is better and make people think they have more 4G coverage.
Technically it does since it's considered just as fast. But technically isn't good enough.

The iPhone 4S utilizes HSPA+ just like the Galaxy Nexus. The only difference is that the 4S has an HSPA+ radio that is limited to 14.4Mbps, just like early T-Mobile HSPA+ devices like the G2x. The Nexus has a 21Mbps radio. Functionally, there isn't a whole lot of difference.
Fortunately, we should see true 4G in the states soon, as T-Mobile plans to roll out LTE-Advanced; which, unlike AT&T, Sprint and Verizon's LTE, is the version that actually complies to all of the initial 4G standards, which are not limited to speed. Unfortunately, it will likely still be quite a while before we see speeds of 100Mbps / 1Gbps, which are also one of the requirements. The backhaul and infrastructure for such a network simply aren't utilized in the US. Also, I don't think we really need speeds like that. The initial LTE we have now is still a battery drainer, where HSPA+ still excels in efficiency. The main benefit of LTE and LTE Advanced is changing from a circuit switched network to a fully IP based system, which HSPA+ partially supports.
Correction: The 4S uses HSDPA+HSUPA, which is close but not identical to HSPA+.
HSDPA+HSUPA Release 6
HSPA+ Release 7
LTE Release 8
LTE Advanced Release 10

3G is UMTS. 4G is HSPA/HSPA+
4G and 3G are not the same in these terms.

T-Mobile's HSPA+ is already at 48Mbps in most cases. No word on the max speed for LTE Advanced yet.
Keep in mind that maximum theoretical speed and maximum real usage speed are two different things, but LTE Advanced supposedly reduces a lot of the issues that HSPA+ has, including the speed degradation that HSPA+ has when it comes to distance from the tower and interference.
Also, to be honest, speed tests are just like benchmarks. They really don't show realistic results most of the time. Besides, most of us really only use about 250kbps-3Mbps in actual real time usage, at best and on high load.

They're already on 48mbps HSPA+. When they deploy LTE, it'll be LTE-Advanced, which is the next iteration above the current LTE deployments by AT&T/Verizon.

Verizon's still busy implementing Release 9 LTE. Less incentive for them to upgrade to LTE Advanced, but possible the groundwork has already been laid for it, not entirely certain of what the differences between the hardware needed at the cell site or the hardware needed in the handset have to be.

LTE is quite horrible for battery life. I'm not sure what the difference LTE Advanced will make. I do know that one of the reasons LTE battery life is poor is that LTE coverage is relatively sparse for the time being, as the radio is having to work harder to get and keep a signal than it would if LTE coverage were as prevalent as HSPA+ coverage is.

[Q] Difference between WiMax, 4G, and WiFi on Evo?

Simple question..
I'm a bit confused about WiMax and whether or not it is (strictly) a cellular communications technology embedded in the Evo 4G, such as 3G and 4G Mobile Data Speeds, and how this relates to the Evo's normal wifi connection.
Is there any crossover between WiMax and WiFi?
Or is WiMax simply a mobile data technology not related to the onboard wifi network card?
Thanks

I think the wimax is part of the 4g service...

WiMax is a type of 4G, with LTE being another type (of 4G)
And yes, neither of those have anything to do with the wifi and there is no crossover involved

^This. Older Sprint phones like the EVO 4G, EVO 3D and Samsung Galaxy S2 E4GT (among others) use Wimax, which was Sprint's original offering for 4G service. Sprint has since gone to LTE (Long Term Evolution) for their 4G service, although Wimax still works in areas where it's already active. Phones on Sprint utilizing LTE include the EVO 4G LTE and Samsung Galaxy S3. Wifi has nothing to do with either Wimax or LTE, as previously stated. A Wimax-enabled phone cannot utilize LTE, and vice-versa, as they are two completely different 4G standards and operate on different frequencies.
The advice is free....the bandwidth, not so much

It really grinds my gears that there aren't new phones available supporting either Wimax or LTE or Wimax AND LTE. I am stuck in Ohio where the Wimax roll out was thorough, and now there is no info on if/when LTE will come here. Eventually people in ohio will all have upgraded to LTE phones due to attrition and we are paying for data plans that we can't take advantage of. I really want a new phone, maybe the new One that is coming out soon, but the drawback is no 4G in Ohio. Sprint really dropped the ball on this one. I'd take a phone that was a little thicker so they could fit both chipsets in there no questions asked.

Thats very true. I think it proabably has to do with the extra work of getting the two to play nice while both being available in one phone, and the extra drivers and hardware required to have both
Definitely what you said though, I'd have no problem with a bit thicker phone that features both but since other competitors are moving towards slimmer and sleeker phones, while at the same time having monstrously powerful processors, it probably wouldnt be a smart move on Sprint part

I was trolling the new HTC One forum yesterday, and did notice that the One might be coming with an LTE radio supporting 800mhz and 1900mhz. This is promising as I believe the 800mhz is what sprint rus the Direct Connect system on. That system is avail in my area so maybe they will use it for LTE? #wantLTE

I remember hearing or reading something sometime back from sprint that eventually they were going to convert the old Nextel iden network over to 4g lte because of the bandwidth it runs on. I also remember that person telling me that this new lte on this frequency would penatrate 2-3x better meaning better 4g lte signals indoors. It may have been a sprint tech who told me on one of the many phone calls I have made to them over the years.
Sent from my ever-changing OG Evo...

Everything you say is true, just replace the word "bandwidth" with "spectrum". iDen was using lower frequencies which penetrate better. You get slightly lower theoretical max speeds, but the connection is more reliable, and people generally agree that's what's important.

can I have my sprint note 2 work on Verizon

I'm sick of slow 3g speeds, my area got wimax so we are going to be last for lte (not that I got any wimax with my gs2) so I've been thinking of switching to Verizon... I'm still not decided but if I do decide can I take the phone with me or is it a waste of 800 dollars if I do it?
Sent from my SPH-L900 using xda app-developers app

I believe it's possible, but I'm not familiar with the process. And it definitely looks like it has some challenges from what I've read on some of the posts for going to TMobile, Boost, and so forth. I would definitely look at some of those threads to see what it involved.
If you did pay $800, you can probably sell it and get most of your money back.
As for LTE, I think if you got WiMax in your area, you'll probably get LTE sooner or later. Maybe you should ask Sprint when they plan to bring it to you market. I lieve in araa that didn't have WiMax, but I could drive fifteen minutes and get to areas that did. But we got LTE in the areas where I live and work. And most of the WiMax near me got LTE as well.
As for 3G with LTE, although the speeds are increased, in my area, it's not that big of a bump. It's only about .50Mbps, especially compared to the LTE speeds. I find I'm averaging around 1.2Mpbs on 3G, whereas before it was around .8Mbps.
Plus, you'll definitely want to see what the Verizon are getting, and maybe specifically on the GN2. Then you'll need to consider how, if any, change to how you'll use the GN2. Are you going to use more data, say more media streaming? I'm not that familiar with Verizon, but I'm not sure if they offer unlimited data. I know they use to. It's possible they may throttle as well. If there isn't a unlimited, then you'll need to know how much you use and how much that usage will cost on them.
I understand your frustration about the speeds. When I had the BlackBerry Curve for Sprint, which was on the iDEN network, the data speeds were so slow, I literally couldn't stream audio without a lot buffering; It was like being back on the 54.4k modem days on the PC. Going to the Evo 4G from that, even without the WiMax available, was like lightening fast. Sprint will bring LTE. It's just a question of when.

It depends on the frequency that the sprint note 2 supports. It has to have the 700 mhz frequency for verizon lte. I havent looked at sprints note 2 frequencys on this phone or not. Look into and see what all frequencies the sprint variant supports.

Lte will never work the sprint lte frequencies are 800, 1900 and 2500mhz and I'm not even certain current device's support 800 or 2500mhz yet as they won't be available until mid 2014 when iden is fully decommissioned for 800 and wimax is decommissioned for 2500

I like to break stuff!

The fact that your area got Wimax has no relation whatsoever to the order or timeframe that it will receive LTE.
For Sprint LTE info please refer to s4gru.com, specifically http://s4gru.com/index.php?/topic/212-network-visionlte-deployment-running-list/ in which they have basically ALL the LTE rollout information. Moreover, if you donate any amount (say $3) you become a sponsor and have access to maps with the towers that already have LTE etc.
