is the HTC EVO worldphone like the HTC TP2?

me(US T-MO) and my friend(sprint) wondering if any of u know if the HTC EVO 4G gonna have the worldphone compatability(GSM slot for gsm networks).my friend currently using the TOUCH PRO 2 from sprint and he has the ability to switch the phone to GSM carriers.jus wondering if the EVO gonna have the compatibilty.if yes defenetly dropping my HD2.

The Evo 4G is a CDMA phone it will not work on GSM and never will since it doesnt even come with a slot to insert a sim card.

yea i know that but the ones that u've seen on every website and videos r not the OFFICIAL EVO i think cuz they didnt even announced the official date but if its CDMA im out of luck and wish for a GSM version of the EVO.

It's 100% CDMA w/no SIM slot. So I guess your out of luck

The big thing about the EVO 4G is the fact that it's a CDMA/Wi-Max. If it had a SIM slot, and you put it on a GSM network like T-Mobile, you wouldn't be able to connect to Sprint's 4G network and lose the one big advantage of this phone. Sure it's got 720p HDMI output and 8MP camera, but other than that and Wi-Max, it's got very similar specs to the HD2.
The other reason could be the fact that they wanted it to run Android, and I have yet to see any CDMA/GSM World Phones running Android natively so they may not have worked out the whole dual mode switching in Android - but I could be wrong about that one.

well.......i guess i have to be patient for something better by HTC on GSM carrier network with ANDROID 2.1.honestly i bought the HD2 and i've flashed custom ROM but still not satisfied at all with WM.i would get me NEXUS ONE but then again better phone will come out by HTC every 3-4 months.as far as 4G its not necessary for me at all.i will patiently wait till end of summer for the better.thanks guys

Look it up. GOOGLE IT ESPECIALLY WITH ANDROID
Sigh why do people get fooled by Sprint's cheap marketing... T-mobile's releasing HSPA+ 3G which is going to be faster than Sprints so called "4G"

Dude....Let Sprint and everyone that is on Sprint enjoy the fact that SPRINT will have one (if not the best) of the best phones ever made for a little while until another one comes out. Tmo has the HD2...now is Sprints turn, chill out!
You got HSPA+? Good for you....we'll have 4G! Is that simple.

Alright I'll settle for that... just trying to make sure people don't fall for the marketing gimmick. I had every carrier and been a loyal customer to them all.... Some people will switch just for a single phone even if they don't have reception in their area. Make a smart move it'll last two full years.

really??
boys and girls.. can we all say "contradiction"?
had to do it to u...
all major carriers will come out with their own "4G" setup, that is to be expected. WHEN will it hit the market; is the real question. Sprint has WiMax and it is being rolled out aggressively.
As they saying goes.."one bird in hand.. is better than two in the bush"
that being said... I live in a WiMax area and have the Overdrive. It is faster than 3G but I can only get 20% signal in areas that I am most in.
I hope they get more towers up in my area!!!!!

So when is this mythical HSPDA+ coming out? WiMax has already been out for over a year where I live, and I've not heard of a single person with WiMax-like speeds on any other carrier. T-Mobile is typically last to the game in that regard, but either way, you guys already have the HD2, which I'd rather have anyways.

WiMax is not certified 4G and will never be. I'm really shocked that Sprint hasn't been called out on this and hasn't had their false adverts of a "4G" network pulled.

why would it have to be "certified 4G?" also, from what I've read from the beginning, is that WiMax and LTE are SO SIMILAR, that it wouldn't cost much for Clear/Sprint to fully convert. The even planned on having a combination of the two services.
methinks you doth protest too much.

wimax and lte use different freqs, converting would not only change the protocol(like software) but the antennas, transponders, receivers and transmitters (hardware)
then all the phones themselves would need new radios (hardware + software) It would be a huge mess, I highly doubt they will convert the technology, hope they just adopt LTE with Wimax and your phone supports both someday. As they already have chipsets that support both technologies at the same time with multiple radios and transceivers. But my money is the conversion of technology will not happen, it will just be integrated into the phones instead of the towers.
Now the wimax/4g thing, wimax has been branded 4g, 4g is a general term...(yes I know it's a stardard and has minimum req's) but the term works for it's purpose; recognition more than a actual "standard". evdo started getting called 3g when the 3g term got popular and was a "feature" and was easier to remember no actual feature was added for them to call it 3g.
The point is the idea gets across, as it is agreed they both generally mean the same thing, you know what it means, they know what it means, and making that kinda correction makes people sound like asses. Much like spelling correctors.

BAM! I knew I read that before.

not everything on you read on the internet is true, but facts are facts.. look
Wimax operates on 2.5Ghz
http://en.wikipedia.org/wiki/WiMAX#Spectrum_allocation
LTE operates on 700Mhz
http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution#Frequency_bands_and_channel_bandwidths
the two operate on two extremely different frequencies, you can't magically change a phone that is built to operate on one freq to start using one that differently. It's just not physically capable of doing it. No amount of software is going to change that.
That article was written in september 09' sprint has moved forward with wimax, they have made their decision, once they put equipment out in customers hands, they will have to cut some customers off by making drastic changes at this point in the game. To jump back at this point would be insanity. The infrastructure is already being built, and in some cases already built.

Why is that? Radios can transmit on all sorts of frequencies... you have no idea how they designed their antennae or transmitters. If Clear says, themselves, that the technology is 80% identical, then it's fairly believable. I've been hearing that for years, anyhow.
Hell, just look at AT&T, they have 3G on all sorts of bands, and that didn't stop them people from using them. This argument is pointless. Clear could have hybrid modems in store, or possibly their devices can already use the spectrum to reference. All I'm saying is Sprint/Clear aren't really committing false-advertising. Comparing some mythical unicorn that T-Mobile *might* have in a few markets sometime soon, to WiMax, which has been out for quite some time, doesn't make much sense.
For now, it's 4G... the fastest, and I believe they have the right to call it that. It's Sprint's fourth-generation network. For years, the carriers bounced back and forth as to who had the fastest network, and you didn't see anyone renaming their from 3G.

I have no idea how they designed their transmitter? This is more or less true, I don't know the exact specifics of their radios, but I have a really really good idea. I used to fix radios for the army... I have an good general knowledge of radio technology.
I don't have the exact links but I've posted some to chipset makers in this forum. One is for the evo's chipset, and one for for a future phone's chipset. The future one has radios *note plural* built in that are capable of broadcasting on both the 700 and 2.5 frequencies. The EVO's is not capable of the 700mhz only the 2.5ghz (among others 800 & 1900 but not 700)
The reason you can tune civilian band and police radios to multiple frequencies is because of transistors. But you're talking a very small spectrum. A common span is like 1-50Mhz difference. The Bigger the gap the bigger and more elaborate the electronic circuitry is required. Having to tune amplifiers as well as antennas. I'm not going to give a lesson on radio broadcast technology cause, well I'm just not.
For antennas they have to be cut to exact length based off their wavelength to preform optimally. As the frequency increases the length gets shorter but the principal is still there. It has to be more or less exact, the more you deviate the less clear the signal will be with the higher freqs the more exact it needs to be. Fudging a difference that big will not work for a clear and precise digital signal.
SO... while a cell phone radio might change it's freqs slightly depending on open channels, the range is fairly close, a radio that operates on 700mhz might go as high or low as 725 for example but it will not, and I repeat will NOT do a 1800Mhz difference. Hopefully that sheds some light on this subject.
I can't go into how their backend protocol is worked, because I honestly haven't ever messed with it and would only be speculation on my part. So it might be correct, the software might be easily interchangeable, but the hardware is not, and clear/wimax even stated so in that article. They said they had equipment capable of both or options or something. But a change is needed for sure. The evo is sprint's flagship wimax phone, and it is not capable of the freqs lte currently uses.... end of story.

Unless you plan on using your EVO for the next 4-5 years , i dont think it really matters. If/when they make this move, there will be plenty of phones to come out that will support the new network. I doubt anyone will still have their EVO's /Epic's by the time this actually comes to reality.

Supposedly the wimax radio could be flashed to support LTE per shinzul and the wimax thread.

this might explain why:
a. the 'featured' echo doesn't have wimax
b. the $10 premium fee for non wimax phones
i think that sprint will discontinue the production of wimax phones and wait for the deployment of lte before they release any new 4g phones. if that turns out to be the case, i don't care if they release a evo with a quad core cpu and 8 gigs of ram. there's no way i'm going to stick around with only sprint's absolutely pathetic 3g.
i also doubt that the evo will be hackable to use lte. what about authentication? lte is supposed to use sims. no way the evo will be able to connect even if some clever hackers get the radio itself to be compatible.

Doesn't bother me too much. Yes, I enjoy the speeds of WiMax, but the battery drain is too much of an issue.

Makes sense, also could explain why we haven't heard about an EVO 2. They could be trying to figure out how to apply a triband radio up in the phone.

I'm not so sure about that, I've seen some mean hacks here in the community, we have good talent here that work hard (and free) to get the most out of our devices so.....I hope our Devs here will do something to keep the EVO alive as the did with the Vogue.

Not so sure about that. WiMax currently require some form of key/pw authentication with Clear to connect. LTE on Sprint will probably require SIM cards to connect, like Metro PCS does even as CDMA network. I don't see how they (or even Sprint themselves) will get around that issue. It'd probably be as futile as trying to connect with AT&T's/Verizon's LTE network with a hacked WiMax radio.

Ok sprint will have wimax and lte dual so that good thing imaging and evo 2 with rev b for 3g 1xadvance and wimax and lte omg and being coverd with that much technology

with speeds under 200 kbps there is absolutely no phone in the world that would make me wanna stay with sprint.
Boy,if this is true they will be losing customers like crazy come this summer.

The story was on Engadget the other week. Technically, the Sprint network guy said it was being evaluated for six months...but with no new Wimax phones on tap for the next six months (that we know of), the conclusion will be the same at the end of six months as it is now.
If they are going to make the move, then throw the switch, and have a plan in place to get us off of our EVO's (and them off of their Epics), even if it's three months out, because then that class action thread that's out there may start looking real good and actually get five stars.
Note: If all that's needed is to switch out the baseband cards and run a firmware update, that would mean that Wimax would have to get turned off, because it's the Wimax equipment that's getting the upgrade. So this won't be a side by side Wimax/LTE network. It's either or...right???

i hope not...
LTE will be bad for cost conscience customers.
LTE is carrier's wetdream... consumers nightmare.

Good riddance? Wimax is a joke in my area (metro Atlanta), to this day I can barely connect to Wimax from inside my house and the coverage map "according to Sprint" shows my area lit up with Wimax. I have to stand by my second story window in my house to connect to it and the connection is "poor", Hell its poor when I go outside.
Love the phone itself though.

How so? If it's what I think...network access can be controlled just as easily on a Wimax network as on a LTE network. It's all IP traffic. Verizon just chooses to control it.

If they move to LTE, all us us evo owner's should get a free upgrade to an lte phone, as our phones will be useless for what we bought them for.

If the rest of the post is also correct, they are releasing a wimax version of the blackberry tablet later this year...which indicates they aren't phasing out wimax just yet. so, no...prolly not getting a free upgrade out of this.

Exactly...2-3 years until they're converted to lte, so wimax as normal.

Old news that I've probably mentioned 6 times since posting in this very section. Project Leapfrog was the codename for Sprint's Network Vision. I'm just patiently waiting for Sprint/Clearwire to officially announce LTE is a go, so I could retire this topic. Sprint's ****ty 3G network will be taken care of by this same project they've mentioned since December.

Isn't wimax to LTE as simple as a change in software? I could be wrong but I was under the impression that the wimax chips in our evos could in theory pick up the low frequency signal of LTE. Then again, I have no idea just reposting what I've heard said elsewhere.

On the tower side, the hardware used in the base-stations can apparently be updated very readily -- swapping some circuit boards, and doing a software update, to make them LTE ready.
As to our phones, there is some disagreement. The LTE spec allows carriers to use frequencies in the range of those that our phones can already receive. Whether the hardware/software combination exists to let our phones receive LTE data, is up to debate. Many say no, but based on the spec, a Wimax antenna operating in the either the 800Mhz, 1.6Ghz or 2Ghz range can receive the signals (see Uplink and Downlink bands here: http://www.radio-electronics.com/in...ong-term-evolution/lte-frequency-spectrum.php), but can the phone discriminate and use what it receives? Who knows...

Great move if you ask me. And I don't know about anyone else but the places I've lived and traveling the Midwest parts of the south and here in the west coast sprints 3g has been my favorite. I also have an att and T-Mobile phone for business.... now talk about ****ty coverage lol.

Sprint switcing from Wimax

Well as many of you read on Engadget about Sprint switching from WiMax to LTE. Well naturally being curious, while I was stopping by my parents house on the way home I asked my dad who worked in telecom for most of my life doing contract work for Sprint. He now has since moved out telecom to some other department, but he still keeps up with his telecom friends who do contracting work for Sprint. Anyways back to the point I asked if these rumors were true. He said Yes they are switching from WiMax, but not to what and that Samsung is providing the equipment. If i find out anymore information I will let you know.

There aren't phasing out WiMax yet from what it sounds like, but since the Evo 4G wasn't designed with LTE in mind then no the LTE won't work on the Evo.

but does this mean that they are going to stop expanding the 4g network, and focus only on getting LTE up in more places? this is kind of a kick in the balls for people who just bought 4g capable devices with sprint.

They'll probably continue to expand and run Wimax on 2.5 Ghz and run LTE in parallel on 850 Mhz.

The way I understand, you would be able to swap out cards in the towers to swap out from wimax to lte... At least on new towers. Is that true?

No offense but you have like 5 posts Including 2 in this thread, and you've been a member here just as long as I have pretty much...I'll believe it when I see it, and as ruge said, the evo will be the compare to as the nextel chirp phones back in the day and the razor, obsolete, trust me, no evo will have lte

the Evo 2A will have lte, I promise

Edit: I am changing this because I read this post wrong. You are right they are about to use Samsung products on the new towers but its not to change wimax, it is to make the towers more efficient and smaller. From what I was told they will use new technology which will allow them to add all services on one tower and be able to free up frequency to build out. It would not be imho to drop wimax because they will be the only ones to utilize it giving them an advantage in developing. Back on topic he is correct they are making upgrades and using new hardware within the towers but I think its imho to have voice/data simultaneous on a cdma network (a first) and they will do it with wimax 2 starting 2012...(that is just my opinion)

I believe I know the article you are referring to as it was in another thread on here and discussed the new PTT service they will use once IDEN is turned off and it will include more speeds and the likes for data.
The way I took the article was that the new PTT phones will take advantage of the new network upgrade they are performing i think its called Sprints Network vision. The multimode base-stations will be the key to it all.
In the end the change allows them to use all the networks more interchangably from what I understand.
I would not expect them to keep the 800MHz band for CDMA PTT. they stated that CDMA PTT phones will be out late this year and if thats the case and they were planning on having them run on the IDEN 800MHz band wouldn't IDEN need to be shut off first? I take it as the CDMA PTT phones will run on the regular network and use data form the 800MHz once they deploy LTE on that. they can't put WiMax on the 800MHz b/c WiMax isn't provisioned in that spectrum at this point.

As I stated in my edited reply it would not make sense to use technology the others are using because it would not make good marketing. Also wimax 2 will be out second quarter or half this year, can't recall, and around the exact same time frame for those new phones. Also the new hardware being supplied to sprint and their new plan is at the core of what wimax 2 is. Which is stated to give better download speed and efficiency thru multi data channels. The company supplying the hardware, Samsung, also The first company to test wimax 2 and said it got 130mbs download, but that's with no one else testing it. But you get the picture.... I hope

My main issue with sprint is signal penetration. Once I get in a building or etc my signal just goes to ****. My coworkers have t-mobile and Verizon and they get full bars sitting next to me laughing at my 1 bar. It has been this way for years.

Sorry to hear that... I also don't get good signal in certain places but hey each carrier has bad spots, when I am in the studio some artist who have iPhone or att don't have any service while myself and engineer have full bars, though he has Verizon

Sprint LTE Agreement with Lightsquared CONFIRMED !!!

Still makes me wonder where this leaves WiMax. Though, Doesnt say whether or not Sprint will actually utilize LTE for its own. BUT we'll see how this all plays out. Never the less, exciting news for Sprint. Cant wait to get some of that 800mhz goodness on my next phone once Network Vision starts rolling out!!
http://newsroom.sprint.com/article_display.cfm?article_id=1989

I'm due for my upgrade in september, but I'm willing to keep my evo and save that upgrade for an LTE phone when its released.

Lightsquared still has to get the interference problem with GPS sorted out.

I wonder if the newer 4G WiMax phones will be upgradable?

They have pretty much done that:

I think that this is potentially great news. Considering that Sprint just posted another nearly billion dollars in loss for the second quarter, they need a shot in the arm badly. Instant nation-wide LTE would be a big boost to them. If they got this along with the new iPhone, I think that they could really start making some headway against the bigger phone companies.
I hope so, at any rate. I am rooting for Sprint (no pun intended) in a big way, because if they went out of business or, worse, were bought by one of the big two, I don't know what I'd do.

a lot of money needs to be pulled somewhere to make this LTE happen. I belive LTE is why Verizon charges so much for data. I hope this don't mean the end of unlimited data in the future.
I'd prefer unlimited Wimax over $80 10gb LTE any day of the week

I wonder if they will be attempting to run Wimax and LTE, using both for some reason..

The contact with the WiMax supplier will expire soon and no word of they will renew it

Ahh, that makes sense then. I don't use 4G much, however it is nice to have it when you need it. I live less than .1 miles from the current edge of 4G in my area.

They will until their contract expires, sprint will run the 2.5ghz wimax signal on a different freq than LTE I believe. I think thats what going on now; if i read correctly sprint is phasing out the nextel push to talk bs thats using their 800 freq and thats what wimax is going to use until they build network vison.

doubt it as that would require swapping hardware dont know if they're going to do that for millions of phones.

exciting
if this is true this is pretty exciting

I talked to one of the service people at sprint and he said its going to be a software upgrade for all the current wimax phones. He also gave me a sneak peek of some of their new phones coming out.

Sounds like a little guesswork mixed with a lot of BS.

I have a real hard time believing anyone at the Sprint store (save for MAYBE corporate) would know anything about new phones, much less be able to show you. In my experience, the in store people are more clueless about their own phones then their users are.
But i digress. I thought Sprint was going to use the LTE on the backend (i can't remember the term, backhaul, backbone, etc) to speed up wimax AND 3G in one fell swoop.

network vision upgrades are part of phasing out nextel iden phones. they are switching all iden customers over to the new cdma ptt thing they have, and will have phones supporting it out later this year. I'm pretty sure iden is set to run till 2013 too.
wimax can't run on 800MHz less they get it provisioned with the FCC to run on that freq too b/c right now its only provisioned for the higher band ones for some reason.
theres no clue what exactly they are going to do with wimax in the far future exactly wether it be for backhaul or something else.
The lightsquared deal gets lightsquare the ability to set up their lte on sprints network and they plan to have it rolled out to first markets in 2012, and will have nationwide coverage over one year ahead of the FCC mandate which puts it around 2014

I believe that you are correct. There was an article not long ago elaborating on Sprint's plan to move to LTE in the future due to both Clearwire's financial troubles and instability, as well as LTE's ultimate higher potential.
It stated that as the move to LTE gets closer, phones that support both will begin to be released. However, I was made to understand that LTE and WiMAX require different hardware so they would both have to be included. This would appear to indicate that a software/firmware update to an existing phone designed for WiMAX would not be a reality.

Sorry bro who ever you talked to does'nt know what they talking about wimax and lte use defferent radios. We will need to get new phones.

They actually aren't even close to working that out yet. As a matter of fact, all of the major aviation related industry groups have just formed a coalition (click this link to see the coalition web page) to fight Lightsquared's proposal. The problem is, Lightsquared's so called "solution" is to require all GPS equipment manufactures to upgrade their devices to eliminate the interference that Lightsquared's system would cause. This is probably not going to happen, as it would cost thousands of dollars each to replace the GPS navigation system in every aircraft that has one, which includes the majority of aircraft currently flying in the US, including US military aircraft. Because it is a flight safety issue, and their current proposed solution would involve millions, or even billions of dollars to implement, I seriously doubt a solution that will allow Lightsquared to go forward will come very soon.
While I am by no means an expert on the technology, my understanding of the problem is that Lightsquared's high powered land based transmitters operate on a frequency band so close to the band that GPS satellite's low powered downlink signals are transmitted on, that they basically jam the signal that the GPS receivers are trying to receive. The result is that GPS receivers are effectively useless when operating anywhere near a Lightsquared transmitter. Sounds pretty hard to fix to me.

wanted to comment again on the Lightsquared LTE talk about the interference with GPS devices. The CEO was on CNBC this past week and when the question came up about the interference it was pretty simple answer and it really made it seem like the media has gotten it all backwards.
The FCC has mandated they have a buildout done by time X and granted them access to spectrum X. Well the interference with GPS devices that has come up is not b/c of Lightsquared's fault, it is b/c the GPS devices are not filtering out lightsquared's freq/spectrum even though they were given years head notice that this would be happening. So its b/c the GPS devices are coming onto Lightsquared's area and not the other way around.
the gps issue is a non issue with regards to lightsquared b/c its not their fault, its the gps manufacturers for not taking proper measures to be ready for lightsquareds rollout when they knew way in advance.
