The 4g portion will only be compatible with sprint's network.
The phone can technically work with other cdma carriers if you know what your doing, and will require some skill to get it to work, or a guide from someone that figures it out. 3G and 1x would possibly work if stuff is configured correctly, the radio is technically compatable with other carriers for everything other than 4g
This doesn't mean you can walk into bell south or verizon and say "hook it up" because that will definitely not work. You gotta make it work, I'm sure more info on how to do it will arise as people get their hands on it, as some have gotten the hero to work off sprints network.

I doubt 4G will work on Verizon's network those are to my knowledge the only major CDMA netwrks (in the US at least).
Verizon's take on 4g will be LTE while Sprint is going WiMax so I seriously doubt the phone's 4G radio will work across the board however the 3G and the call CDMA radio should work.

From what I gather the radios will operate on different frequencies
wimax on 2.5 GHz
http://en.wikipedia.org/wiki/WiMAX#Spectrum_allocation
lte is on 700 MHz
http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution#Frequency_bands_and_channel_bandwidths
so I'm going to go ahead and say not a chance of it working.... although I may be wrong

Plz tell me more

more about what? the different frequencies?
Um well, for example you can't tune your tv to the radio channel even though they use similar technologies. (well you could back in the day depending on your tv but that isn't helping my point ) But it just uses different frequencies, look at this for a better understanding of frequency allocation,
http://upload.wikimedia.org/wikiped...locations_Chart_2003_-_The_Radio_Spectrum.jpg
The chart is rather busy, but see how each is boxed off? That is what a radio designed to operate on will be limited to. the wimax and lte are very far apart from each other in this spectrum, it will be extremely unlikely it will be able to operate on both frequencies.
This talks about the radio used in the EVO.
http://www.thesearethedroids.com/2010/03/25/sprint-evo4-chipset-qsd8650-supports-gsm-and-hspa/
Not an insane amount of LTE info is out there other than what's been cleared by the FCC, more info on the radios that will be used as soon as one is released. I know one thing, the freqs are different so the same roaming you enjoy now with sprint 3g will not be shared with 4g with verizon when they kick off LTE. 3g roaming will stay unaffected per sprint and verizon's roaming agreement because of same technologies and freqs used. Only the 4g portion will be different.
One chipset to be on the lookout for is this http://www.beceem.com/ends_4G_debate_LTE.html it will support both technologies, but it unfortunately will not be in the sprint EVO. Be on the lookout though as something with this chipset might counter the aforementioned roaming problem.

Not that my phone ever roams (I don't travel much), but when it does my Sprint will only go to Verizon? Did I understand that correctly?

Yes, your Sprint phone will only roam on Verizon's network cause their both cdma networks.

Luckily for Sprint users Verizon covers more area than any other carrier in the US.

However, it’s almost guaranteed that you won’t be able to use over half of those networks because the phone will lack the right amplifiers and/or antennas

I highlighted the part you need to re-read in my last post (it was a pretty lengthy quote)
but unless you plan to electrically (as in soldering iron and tiny electronic parts) modify your phone, don't plan on it being able to actually use those other frequencies.
They are not advertising it as a world phone (sprint has made worldphones before and advertised it because it's a selling point) so they are not going to put needless hardware that they won't enable, doesn't make sense, and it costs them additional money to make it that way.
If you did get that modification in, you will then have to edit the programming of your phone's cellular radio to talk on those frequencies and towers because they will not be built into whatever radio firmware ships with it because it wasn't needed because the amplifiers were left out. That will be an almost as equally difficult task.
I don't know man... good luck if you don't believe me.

Sprint Killing Iden and Moving to LTE?

Recently read that sprint will be phasing out the iden network by 2013 and Dan Hesse Admitted Wimax was a failure and is considering the switch to LTE.
Could a switch to LTE ruin our 4Gness on our beloved Evos or would they still work?
http://www.theregister.co.uk/2010/12/09/clearwire_sprint_wimax/
http://www.dslreports.com/shownews/Sprints-25-Billion-Network-Improvement-Plan-Hints-At-LTE-111703

Im just going out on a limb here but gonna throw my thoughts in on this . The phase out wont be till 2013 . With that being said most of us on the Evo will be well into a new phone by that time . General life span of phones (I said general) seems to be one year maybe two at most before someone jumps ship and gets another phone . I have also read that Wimax is an older technology that has been around for a while and the next logical jump would be LTE much like verizon is pushing . Now if for some reason you still have an Evo by the time the phase out is complete , I would suspect Sprint would either offer their customers an upgrade to work on the new network or atleast reduce the bills of the current evo owners still running an evo at that point . But from what I have seen and said in this post the likelyhood of any of us having the EVO in its current form by that time is very low . Its also possible the next gen of phones being released next year will start incorporating the LTE system (say for the sake of argument EVO2 LTE) to adjust to this change .

Wimax 2............ftw

Current wimax network can be easily switched to LTE via software upgrade that's why the current wimax buildout will continue. Also wimax is backwards compatible with wimax 2. So sprint has a couple ways it could go. And they own a lot of spectrum.

Expect ptt over ip and not in the failed Qchat form. Most likely over 4G(wimax1,2 or LTE) data. Sprint has plenty option. They just have to play it right.

hmmmm...maybe wimax and lte along with cdma and gsm...world wide phone..anywhere. Maybe Sprint quad band phones with quad core cpus in next 5-10yrs? Quad band with quad core.."4x4" on 4G. ok..dream over...
Youd need a 12 volt battery too. lol

I read a while back that sprint chose WiMax as its "4g" provider because the infrastructure was already in place since clear had been launched. And that if LTE deemed a better route that the WiMax network could be patched relatively easily to run LTE. Im not worried about it. If sprint was the first company to have 4g im pretty sure they wont leave their current WiMax customers without high speed service if Wimax is pulled off the market. But remeber as well that the article specifies Iden which is nextel. Thats a conpletely different animal. Only time will tell.

No. The transmitters use a WiMax card to transmit WiMax signal. All they would have to do on their end is swap the cards in the transmitters for LTE cards and then patch the software to interface with them instead of WiMax cards.
The bad news is that for us Evo and Epic (and Overdrive) owners, we won't get LTE with current hardware. And I know they'll use the "early adopter" excuse. Either way, I love my Evo, 4G or not. I hardly use 4G. I just hope they do the right thing and offer people money back or towards an upgrade. WiMax is fast, but isn't that great to begin with. I'd rather have LTE seeing as how it's becoming an international standard. The only thing I don't like is the cluttered frequency. Verizon and AT&T will both be using 700 MHz.

Thats good the two technologies are that compatible, I didn't know they could be used like that. You're right about Sprint having the Spectrum for it too. My guess is they tried getting rid of IDEN a few years back to use that spectrum for 4G but couldn't because of all the people still using it. The higher frequency WiMax is at now is what's holding it back.

They're compatible from the transmitter's end, not the receiver's end (our phones).

This is true until the G2 came out. That would be the only phone I would leave sprint for. I think the problem that came about with the Evo was it was rushed out for sprint. They could have cleaned up a bunch of problems before it even hit the street. **off soapbox**

As long as they don't switch frequencies, then they will need to transmitters as well. Although they could probably leave the infrastructure they already have in place and finish the rest of it on the other frequency.

No, what I mean was that LTE and WiMax are not intercompatible in themselves.

Im glad to see that they can switch between wimax and LTE easily. I did not know that. Hopefully all the companies will have a roaming agreement in place. Also, isnt the range of LTE further than Wimax or is it the other way around?

wimax and lte
My best friend worked for sprint. Now works for AT&T. Wimax is not the problem. LTE is a different technology. What you have to understand is not the sofware but the signal. The Wimax from Sprint is running between 2.0 and 2.5 ghz. The problem with this is the structure penetration. 2.4ghz, if you remember is what older home cordless phones run on. Get to far away and, bam, no signal. Sprint could switch to the LTE format the the carrier frequency in the 2.0 to 2.5ghz spectrum will still not be able to penetrate structures well. My friend says the spectrum needs to be cleared up. vhf uhf tv. WTF. Get rid of them. You need to be at the 650mhz spectrum (his personal choice) so the the wavelength of the carrier wave will be able to penetrate building/structures. And pagers? Are you kidding me all phones double as a pager. Dump them. A doctor is going to get a page and use his cell phone to call in? waste of spectrum. So sprint needs to change the carrier frequency of wimax or lte (if it changes its mind) so that you can get your service indoors. The carrier frequency only is a delivery system(such as a semi truck delivering a tv). If you have a bad truck, tv does not get delivered. Know what I mean. All carriers need some free up of current spectrum so we can get some real penetration and better bars. I hate being a nerd. But WFT. Get a divorce and get an new life.

Sprint to LTE???

Welp, looks like it's going that way...
http://www.engadget.com/2011/02/15/sprint-evaluating-switch-to-lte-over-the-next-four-to-six-months/
...thing is, there hasn't been any new WiMAX phone announced this year, so either they're relying on riding that EVO and Epic wave to get new WiMAX customers, or maybe they do have something up their sleeve.
In any event, I don't see that many new customers signing up for Wimax, so to LTE Sprint will go. Now what do we do with our Evo at that point?

Other than the shifts but if they give me a choice to choose a new phone I'm in

It's like sprint is playing the "you can't get mad at me, i'm not touching you" while holding hand in front of face game with all these changes that piss everybody off without letting them go etf-free

Oh, they would have to provide us with a LTE phone if they do switch. At least offer us a pretty hefty discount. Otherwise, I see a huge class-action lawsuit headed over their way. I'd love for this switch to happen. WiMax is just not cutting it.

From the user comments of the linked article:
They're still going to roll out WiMax and then just add LTE functionality later on. Again, It's just a baseband card swap and a software upgrade. The phones would probably use a dual-mode WiMax/LTE chip (like the one introduced last year by Beceem). Sprint did a pretty good job of future-proofing their network and WiMax was a better/cheaper choice for "4G"... Verizon was having some major 3G/4G handoff issues in mid-December and there's still no word of that being resolved. That's a major issue for Big Red and could slow or kill LTE adoption (imagine having to either wait about 2 minutes or even having to reboot your phone whenever you go from 4G back to 3G). I'm not even getting into AT&T and Verizon's LTE spectrum limitations.

But they would eventually have to actually flip the switch to LTE.. would they not have to pick one or the other?

As long as I got a huge discount on an LTE phone, I'd be okay with this. I like WiMAX, but for the dev community, LTE is going to be way better.

They're facing this scenario now, if they turn off the iDen network to use LTE. Some speculate that Sprint will lose a lot of money on this, but all they have to do is sell the spectrum that wimax is on now. T-Mobile would buy it...

Not really cause Wimaxx is just another channel or frequency. I mean they still have 2G/3G and now 4G, LTE will just be another channel that they will be able to accomidate

I say the only reason why the would make that switch is to keep up or ahead with the other carriers, t-mobile, att, Verizon so why not make the switch everyone gsm and running on sim chips mmm nice different phones on different networks sounds fun

This is what scares me. I know LTE is faster than wimax. (Job I work at sells both Wimax capable cards and LTE broadband cards now and I have installed both on computers, and speedtest wise, LTE was pulling 15 down and 1.5 up. Wimax in our area usually does 5-7 down, and 1 up.
But I don't want Sprint to be able to decide that what I do with the data access I am provided isn't what they think I should. The fact they can block sites, charge rates for sites, and so forth is very bothersome. It is the same crap certain ISP carries are looking to do.
It is this reason (among data caps) that I decided not to wait for the LTE thunderstorm phone(or w/e its called, im kinda tired ) and go with verizon over sprint.
I just with their Wimax was better in the Cincinnati, OH area than it currently is. Map shows I should have 4G outside everywhere but my backyard. And I barely get it in my front lawn where I should have a perfect signal.

Does anyone have a link to the story of how carriers can control access to the web using LTE. I read it but don't remember where. This is very disturbing that the carriers will have this much power over our web viewing habits

Don't worry fellow evonauts, they (probably) won't block your fetish adult entertainment.
But seriously, better speeds would be awesome, better coverage would be great but the capability to throttle or block what i want to do with my "unlimited" connection is unacceptable.

Here's some things to remember before anyone gets up in arms over this:
1. Between the Sprint, Clear, Comcast, and Time Warner brands there are millions of users on the Clearwire WiMax network, many of whom are in contracts based on WiMax devices or services. They're not going to just flip a switch in a few months and suddenly none of us have 4G anymore. I would not expect to see much further WiMax development beyond what's known about at the time of any LTE announcement, but by the time the WiMax network goes dead anyone posting here will have moved on to a newer phone.
2. There's no reason at all that this would need to be done as an on/off type switch. They install the hardware bits needed for LTE, then switch channels of their available spectrum over as dictated by utilization. AT&T's migration from TDMA to GSM after the Cingular buyout took years to complete.
3. The Evo Shift just came out and the Blackberry Playbook with WiMax has been announced and given a rough street date. Like most of us existing users, these users will likely for the most part be in contracts, meaning if Sprint does anything that significantly impacts the usability of those devices (such as terminating WiMax service) they'll need to either give us cheap/free upgrades to LTE phones or let us out of contract ETF-free.
tl;dr version: LTE is probably coming, since Sprint's rapidly becoming the odd man out in the 4G cell world, but there's no reason for current WiMax users to panic.

Any ISP has about the same power. It has nothing to do with the last mile medium and LTE will change nothing about this.
Regarding tethering, there is no way to tell for certain by looking at the data transmitted whether a user is tethering or not when a modern smartphone is involved, since they're capable of doing anything a full PC could do with that data connection. Certain types of data may be suspicious and more likely to have come from a PC, but nothing could be proven to any reasonable standard as long as they have not loaded a "tattler" program in to the OEM ROM to explicitly identify tethering. Assuming a rooted phone, this could be removed and of course would not even be in AOSP-based ROMs.

Good rational post. Thanks.

Maybe I'm just misunderstanding something but I'm taking this switch from WiMAX to LTE as Sprint just has to change the cards on their ends and send us current WiMAX users a software update and we can use LTE.

Half right. The Wimax chip in the Evo is straight Wimax...no LTE capability.

Since the wiMax is actually from Clear as far as i know, Sprints choice shouldnt really matter in the long run. WiMax wont disappear so your "old" phone should work, and Sprint actually having its own 4G network means more than likely better battery life and better connection/coverage

anyone heard about this

i got a call from my buddy from sprint and he said in 20 days sprint is gonna buy and get verizons 4gLTE
anyone know if this is true or not.
i know that the nexus is getting a update hopefully this week that is suppose to boost 4g and wifi connection. so thats a bit of a hint
what you guys know about this

I have heard that they were going to be using LightSquared possibly. Not sure if that is VZWs LTE provider, but since Sprint uses VZWs 3G towers, I can't see why they won't strike a roaming contract with them again.

An LTE roll out for Sprint will happen.
It's been talked about that Sprint may embrace both LTE and Wimax standards.
However, it's not an instant process and a phone would have to have an LTE radio to use the LTE band.

In 20 days some sort of deal might go down, or they might start some sort of project, but there's no way they can instantly switch and certainly not in such a short timeframe.
IF Sprint drops Clearwire then yes, Wimax would not work with Sprint phones.
It's been suggested that Sprint may go to quadband phones though.
Who knows. I'm not even sure Sprint does, which is part of the problem.

In 20 days some sort of deal might go down, or they might start some sort of project, but there's no way they can instantly switch and certainly not in such a short timeframe.
IF Sprint drops Clearwire then yes, Wimax would not work with Sprint phones.
It's been suggested that Sprint may go to quadband phones though.

Well in the link he posted above, the article said that they plan on making a Sprint-Clearwire-LightSquared combination.
its a stretch to make it happen but its possible

I wouldn't doubt it.
Sounds like a good idea actually.
And it coincides with the idea that Sprint might just run both standards along side CDMA (which would eventually be phased out, eventually.)
Both LTE and Wimax have uses.
Why shouldn't both technologies be used for what they do best?

ok just so i got this right and don't start rambling about things idk
LTE is 4g alone or is it Both 4g and Wimax.
cause if thats the case then why hold onto Clearwires Wimax?

Neither are true "4g"
Both are just different technology standards (well not even standards lol).
Its just like wireless a, b, g or n.
Just different "standards" for wirelessly transfering data.

In 2009, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users).[1]
http://en.wikipedia.org/wiki/4G
Basically, 1 Gbit/s when not moving, 100mbit/s when moving and VOIP.
Everything runs through data.
Texting, Voice as well.

lte is awesome, if you use your phone as it comes out of box. ask any thunderbolt owner what happens when you throw an aosp rom on top of the lte radio...

It has nothing to do with LTE and all to do with the spectrum used by Verizon.
Wimax would be just as "awesome" if at the same frequency.

no, your not following me. im not talking about lte itself. im talking ril and the actual radio.

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.

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.
