[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.

[Q] Sprint to switch to LTE

I read an article on engadget that said it was a possibility that sprint would be switching to LTE because of Clears(Clearwires) financial problems. Anyone have anymore info on this ?? Will our EVOs work on LTE? IS there a special radio required for that or just software?

There is a thread on this in the general section. And I would say no, as it would be GSM and requires a simcard, and the Evo radio can't access it. But it won't happen immediately.

LTE is not even related to GSM.
I have been reading different theories. One is that our current 4g antenna can handle LTE with an update, but I am not sure I buy that one.

Well I never claimed to have all the answer. But as to your second point, I don't buy it either doubt the evo would be able to support it.

Verizon uses LTE on cdma (same as Sprint). As for LTE being compatible I've heard rumors an update to the radio is all that's needed.
I assume if its not they will keep us wimaxers on clear and in 2 years or so we will all be upgraded anyway (new phones)

ok to clear this up since everyone seems to be misunderstanding everything with this.
The WiMax radio and the LTE radio are very different. As far as I am aware, LTE requires a sim card. WiMax does not. The Towers that sprint has put up for WiMax can apparently be converted to LTE towers by changing one piece of hardware and issuing a software upgrade.
Your Evo will not be able to access LTE. It does not have an LTE card in it, it has a WiMax chip.
in the real world, LTE is the faster network than WiMax is. The downside is they can control what you do or don't do. What websites you go to, etc.
in my experience I have seen LTE do 15-20 down and 2 up on a broadband card. Wimax I have never seen past 10 (due to sprint limiting this anyway) and it is usually around 4-5 on average.

ACTUALLY, wimax end of life is suposed to be able to hit 140 mb/s and LTE end of life is only looking at 100 MAX... so in the long term wimax is much faster, most people have said that it's mearly the way clear rolled it out that makes it so unreliable and slow.

Sprint working on spreading 4G network?

I know that when I purchased the Evo I was kind of upset that I didn't have 4G because of my area. Now i'm onto the ET4G and still no 4g =/. What's my solution? Move to the city to get 4G? Curious I suppose and its a shame to have a 4g capable phone and not get 4g network.

Trust me I was with ATT and didn't get 4g either and not even 3G because a lot of there network isn't even 3G build yet. And they are way more expensive. Though now I at least have 3g with Sprint.

i hate to be the one to break the news to you bro. all the WiMax 4g towers that are currently installed and operational right now are all the 4g WiMax towers there ever will be. Sprint canned it since it was on a not power/non building penetrating frequency of like 2.6 ghz or something. verizon i beleive uses like 700mhz or something close to that which allows the single to penetrate buildings deeper and travel farther. Sprint just anounced its "Sprint Visions" plan i beleive its called. What it entails apon aproval from the FCC i beleive since its 20 or 40 mhz away from the GPS frequency. they are moving to LTE towers like Verizon. what does this mean for your WiMax handset? it will never see the light of day with 4g. it will not work on LTE as the 4g chip does not work on those frequncys. in early 2012 sprint will start to release new handsets with the new radio chip in them. i beleive they said it should all be deployed within 3 years? also that are moving to Rev B 3g so its faster. also will be able to use the internet and phone voice calls at the same time. they use all the push to talk nextel for the new 3g or something like that. idk, people if you know whats the plan better than i please feel free to correct me. but thats just the general idea of whats happening

You summed it up pretty well. WiMax won't be expanded, but it will continue to be supported for a few years. Sprint actually basically has 3 types of connections. EVDO, Nextel's PTT, and WiMax. They'll be able to put a multi-band antenna up at all the disparate sites, providing some awesome coverage! Of course this is still a ways away.

4g
Sprint hasn't canned 4g in my state they just put up two more towers one in my town and one about 6 miles outside the north side indy which will make a total of 4 towers in indy and that doesn't include the iu and iupui campuses. And they are putting up more so i don't know where you got your info that sprint canned 4g but they aren't now we are hosting the super bowl and that could be why They are putting up towers left and right in my city.

Sprint hasn't canned 4g, but is changing over to lte next year. All of this information came from the investment talk they gave I believe at the start of October. Sprint covered how this would work and that work on the towers was starting in order to move to the new 4g. Wimax will still run side by side with lte for a few years.

Does Sprint's 4G LTE Rollout Upgrade 3G Networks?

Once Sprint officially rolls out 4G LTE, will their 3G signal and data speeds improve?

That would totally depend on the market you're in.
The teams that are going around putting in the 4G upgrade are doing multiple things depending on the market.
For example, I asked this question specifically to a sprint tech the other day when purchasing my S3.
I live in Miramar/Pembroke Pines Florida (Just West of FtLauderdale).
Signal here is great in some spots (near I-75 or the turnpike) and almost non-existent anywhere else. Hell the other day I saw the nice little "Hey you're now roaming" message on my S3 (I never saw that on my Evo, though the signal was horrible).
The tech said that they are in fact upgrading EVERYTHING in my area, 3G, normal phone cellular and 4G LTE (they said the wimax would not be upgraded of course). It took them a minute to find the info as they had to look it up for my specific area to see what is and is not being upgraded.
She mentioned specifically that it wasn't just upgrading the current towers, but putting in more to improve coverage in areas such as Plantation, pembroke and Miramar specfically.
So my advice is to either wait and see what happens, or try to contact sprint and find out about your area.

[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.

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.
