I think this would be a terrible idea since i switched from t-mobile to sprint for better reception.

P.S. Just realized that I posted this in the wrong section. Mods please feel free to move to the appropriate catagory.
if they do it will suck but i hope they switch to sim cards
Even if T-Mobile's parent company buys Sprint, they will never change the existing technology. If the deal happens, I bet they don't even change the name. Just because the parent company of T-Mobile buys Sprint doesn't mean that Sprint goes away completely and all your handsets now say T-Mobile...it just means you'll be forking over your paychecks to a different money hungry conglomerate.
I.E., Sprint will never use SIM cards, nor will they switch over to GSM...that is until maybe 2010 when LTE gets rolled out, but that's a horse of a different color.
I hope they dont switch to the sim cards those are jus easy ways for someone to steal your expensive pda
coming from T-Mobile to verizon I love the extra data speed but I hate that VZW using CDMA (i.e. no SIM cards) because I travel around the world extensively and stupid CDMA means I have to have a different phone (and number) on a GSM phone so i can use it overseas.
CDMA might be great here in the US, but it sucks everywhere else in the world. GSM might be older technology, but I have never found a country yet that my old nokia gsm phone doesn't work immediately as soon as I step out of the plane.
Why cant people just get along and all start using the SAME technology all round the world.
(I am not originally from the USA, so don't get me started on PAL vs NTSC or ATSC vs DVB. I cant get any AV equipment from OS to work here in USA or vice versa - forgetting even about the voltage difference!!!)
Ya, unfortunately CDMA really is the best option here in the US. Hopefully with Verizon going LTE for 4G we will see more convergence with global standards. And even if GSM is older than CDMA voice channel technology, HSDPA gives up nothing to it's CDMA counterparts (EVDO Rev A). How many 7.2 or 14.4 mbps EVDO networks are opperating in the states? Zero.
See that's the thing though...sadly GSM networks in the U.S. suck the proverbial big one when it comes to voice quality. As I said in my previous post, I have my fingers crossed that when LTE is rolled out in a few years, it fixes a lot of the problems here in the good ol' US of A.

Is LTE the natural progression path for both CDMA and GSM? If that would be the case then things are looking up for equipment compatibility.
gc, Agree though that in US, CDMA really is king - for now.
I don't buy what the articles says about Sprint users having to get GSM phones...
more than Half the value of sprint assets is in the infrastructure they have built, Not the actual subscribers who use that infrastructure.
What is more likely is that T-Mobile will add GSM support to the existing Sprint towers so that their coverage is better but keep the CDMA business since that is the one most prevelant in the US and the one most likely to generate additional revenues based on relay calls from other CDMA carriers.
At some point the phone industry has to start building dual format phones for those who need both GSM for overseas and CDMA for US use.

To my knowledge, LTE is actually unrelated and incompatible with any existing CDMA or GSM technologies. It would be a new from the ground up system. LTE seems to be the path that the global standard will take though, and since GSM (and its related data protocols) is currently the global standard, the two are often associated.

There are a few (mostly Blackberries I think) but they are nothing that I particularly care for.
I dont know where they came up with sprint switching to gsm,my guess is the article was written by a gsm fanboy. Eventually of course,they would want to transition everyone onto a single network.A model for this is the sprint-nextel merger. Sprint still runs an IDEN network along side their CDMA netowork. In that case there were reasons to keep IDEN around,since PTT did not really work well over their data network. (I understand that EVDO rev A has QOS features that make it work better)
If sprint ends up merging with T-Mobile,I expect that something similar might happen. T-Mobile does not have nearly as good of data coverage as Sprint does. (Although I have heard rumors of HSPDA coming to T-Mobile,but havent really looked into it that much) For the time being they would run both networks. Its possible that they might actually convert the whole network to CDMA instead of GSM due to the fact that sprints network seems to be more developed.
In that case,they would probably stop selling new GSM handsets. When a customer wanted to upgrade their handset,they would have to get a CDMA unit. Eventually,there would be very few GSM users left,all of which would have older handsets. They would then offer those last few new handsets and discontinue GSM service. Other carriers have done exactly this in the past. I imagine that roaming agreements with at&t would actually allow them to turn off their gsm towers before they had transitioned those last few customers to CDMA. At the end of the day,they of course get those last customers to sign new contracts,a win for Sprint-Mobile.( T-Sprint? S-Moprint?)
Similarly,if they decided to go to GSM,they would have to wait untill a HSPDA network was ready. The transition would go the same way.
To my knowledge, LTE is actually unrelated and incompatible with any existing CDMA or GSM technologies. It would be a new from the ground up system. LTE seems to be the path that the global standard will take though, and since GSM (and its related data protocols) is currently the global standard, the two are often associated.

This is untrue. LTE (Long Term Evolution) is the code name given to the project that the 3GPP is currently working on for their 4G standard (Release 8), and is aimed towards improving the current UMTS standard. The outcome will be modifications or extensions to UMTS, not a brand new system. The architecture we will likely see will be E-UTRAN (built off of existing UTRAN) standing for Evolved UTRAN which is on the access side, and EPC (Evolved Packet Core) on the core side, which make up the EPS architecture (Evolved Packet System).
Verizon has already announced they will be using "LTE" as their standard instead of UMB which is the successor in the CDMA2000 family. AT&T will also be using it as their 4G standard, but will provide HSUPA and HSPA+ as bridge standards.
Now, as of right now, Sprint on the other hand has announced they will be using WiMAX as their 4G standard. IF the Sprint - T-Mobile merger happens, we will not be seeing Sprint customers walking around with GSM handsets, instead we will see both Sprint and T-Mobile customers walking around with either full WiMAX handsets, or if they choose to, dual CDMA + WiMAX handsets.

That's interesting. I was under the impression that although LTE was an evolution of current standards, in practice there would not be backwards compatibility with existing networks. I could very well be wrong, so please provide some evidence to the contrary (no wikipedia please).
Also, I believe that Sprint is second guessing their position on WiMax. They may still go forward with that technology, but I think (based on conversations with people from Sprint) they are evaluating other options now as well.

Thanks for the links.
While it appears that most networks will support both LTE and legacy technologies concurrently, the two are not interchangeable. A strictly LTE device wouldn't function on an HSDPA/HSUPA/UMTS/GSM network, and vice versa.
From the first link: "...co-existence with GSM/EDGE/UMTS systems..."
The two will not interfere with each other, and they can even be run from the same tower, but that is as far as it goes. They are still totally seperate technologies.
This is illustrated further in the second link you provided: "Co-existence in the same geographical area and co-location with GERAN/UTRAN on adjacent channels." The two cannot operate simultaneously on the same channel. Towers that support both LTE and existing technologies will be able to hand off the connection from one to the other though:
"E-UTRAN terminals supporting also UTRAN and/or GERAN operation should be able to support measurement of, and handover from and to, both 3GPP UTRAN and 3GPP GERAN."
"The interruption time during a handover of real-time services between E-UTRAN and UTRAN (or GERAN) should be less than 300 msec."
This supports my original statement. I may have been overly broad in saying that LTE is completely unrelated to existing technologies. There are undoubtebly some similarities, but the radio technology is radically different than anything currently used.
In practice, I would assume most devices will support both systems until 3G (and earlier) technologies are completely phased out. It would be a similar situation if Sprint decides to deploy a WiMAX network. The first WiMAX devices that appear would naturally support Sprint's existing networks as well as WiMAX. The device may operate on both WiMAX and EVDO, and may even be able to seemlessly hand off between the two, but that doesn't mean they are related.
You seem to be forgetting the original question you were answering though. One of the posters had asked if LTE is the natural progression path for CDMA and GSM networks. You answered him by stating that it is completely unrelated and is a completely new system altogether. I corrected you by saying that it is untrue as LTE is the natural progression path for GSM/UMTS/HSDPA networks as it is wholly based off current UMTS networks. I then went on to say that Verizon opted to vary off their natural progression path towards UMB instead by choosing to adopt LTE.
Though the radio/network infrastructures will be different, current GSM/UMTS/HSDPA providers will continue to support GSM/UMTS/HSDPA alongside LTE as it is their natural progression path. I wasn't trying to say that a GSM handset would simply work fine when trying to use a PURE LTE network. Providers will not just wake up one day and pull down all existing architecture completely expecting everyone to go buy a new PURE LTE handset. Just like when digital networks first came out, analog stayed around for a WHILE before they pulled it down...and handsets had BOTH analog and digital capabilities.

I agree that I may have oversimplified by calling them completely unrelated, but I think it is a bit of a misnomer to call LTE the natural progression path for one and not the other. Implementation of LTE will require a rollout of completely new network infrastructure. It is not merely an update to existing UMTS hardware. The two protocols have virtually nothing to do with each other, other than the fact that they were both introduced by the same regulatory body. It is the same thing with UMB. Just because CDMA and UMB were both developed by Qualcomm, doesn't imply a great deal of similarity or interoperability. UMB is only considered the natural progression of CDMA (as LTE is to UMTS) because they are both sanctioned by the same group. I don't think it is any more of a natural progression for an existing UMTS network to implement LTE than for Verizon, as both will have to roll out entirely new systems. The only difference would be that Verizon's network would be a mixture of CDMA and LTE, while the global standard would be a mixture of GSM/UMTS and LTE.
It looks like you are definetly right about Sprint going WiMAX. The Sprint/Clearwire deal that had previously fallen through is now back on. Several other companies like Intel, Google, and Time Warner are now investing in the deal as well. WiMAX it is.

Well.. there goes standardization down the toilet..
I think they do it deliberately so we can't port or devices from one carrier to another.
Yeah you'd think Sprint would smarten up too when they see every other top carrier in the U.S. choosing LTE as their 4G solution...

the phone has HSPDA+ (4G)
the question is if your phone company supports 4G or not
even if 4G is not an option for your cell company, you can still get 3G with the phone
yeh the question is whether uk phone companies will support hspa+ as it is an extension of 3g really?
because if not they shouldnt be advertising a feature that is disabled.
or due to the recently announced 4g spectrum auction, they are just meaning it will be compatible once the 4g network is set up.
its just hsdpa+ enabled and thats that... what carrier the consumer will be using and if the carrier supports it, is none of their business. they sell internationally just because uk carriers dont support this yet doesnt mean that they arent supposed to describe exactly what they are selling...
no, you guys aren't understanding me. it is a uk website, not an international website of samsung, it is a uk seller selling to the uk, we have tranding standards laws so products arent missold.
do any uk people know if this is possible in this country?
I'm not quite sure you actually know what HSPA+ is - the phone does support this wireless standard, but for it to be useful to you your cell provider needs to have HSPA+ capable stations in your area. They are selling you a capable phone, not cell phone service - and the maximum speed this phone can attain is higher than other phones maximum speed.
And, of course, UK providers do support this standard. You are most likely to get a HSPA+ signal in metropolitan regions. If you absolutely have to know if your area is covered, you need to research further - but this will change over time, as more and more regions are upgraded.
But even if no cell phone provider in your area had capable stations it wouldn't be mislabeling as the seller is only describing the capabilities of the phone - you could be buying it for use outside the UK.
You really need to research before asking pointless questions.

I am sorry if I wasn't clear with the question, I was wanting an answer/debate as to whether the UK will or already has HSPA+. I was unaware it does as we haven't sold off the old analogue wireless spectrum yet. When this is sold off (sometime mid next year at the earliest) then the networks have to implement it, so more delay.
Having worked previously for many years in electrical retail, if I told someone that their new HD tv made everything HD, that would be misselling, and breaking the law. Same logic applies to the website

Is this then true that HSPA+ is compatible with the existing 3G networks? There is no need for upgrading the wireless transmitters? I know that Vodafone has done trials but I do not know how these would be done.
Also I don't really think this is a pointless question as for UK users the SGS2 seems to be the first HSPA+ phone available. Again I know that Vodafone has done trials but no phones that have HSPA+ that are available internationally have been sold in the UK with this technology.
Also PartyMango, they are selling you a "cell phone" service as they are a 3rd party seller of Orange/T-Mobile/3/Vodafone services, CW take responsibility for the contract. CW do not sell phones this expensive unlocked or payg.
But thankyou for telling me that there is HSPA+ service already in the UK, as my phone doesn't support it I would never know and having tried to research it I couldn't find anything so asked here, and tried to let potential UK buyers know that a "4G" phone is coming soon fully capable.
Edit: Btw, I don't think locked phones on UK contracts would have cheap rates for being able to use HSPA+ data abroad.

HSPA+ is the next revision of current 3g technology. Providers do need to upgrade their transmitters, but that doesn't necessarily mean replacing the hardware. Almost all recent transmitter hardware sold by equipment manufacturers to cell providers is firmware-upgradeable. Most equipment installed now is even prepared to carry LTE signals at a later time.

I'm not sure about HSDPA+ but I've had HSDPA on my HTC Hero for the past 18 months with T-Mobile UK, and I know Three UK have HSDPA capability too.
According to GSMArena:
The Hero has HSDPA 900 / 2100
The original SGS has HSDPA 900 / 1900 / 2100 (And when I played with a SGS in a Three store it had a H, so it definitely worked with Three's HSDPA network)
SGSII has HSDPA 850 / 900 / 1900 / 2100
So I think it's just similar but with more frequencies? Not sure, but hope it helps somewhat!
EDIT: I looked it up on Wikipedia and HSPA+ is a much faster connection, I'm sure we don't have that in the UK yet, perhaps it's just a misprint on the website?

HSPA+ does feature different speed levels, on the phone side as well as on the network side - many cell providers all around the world do have it, UK providers too. It would be very odd for the UK networks not to feature this technology, as opposed to most domestic european cell networks. But rural areas most often won't have HSPA+ coverage.
And it is no misprint as the website is advertising the phones capabilities, not a specific cell providers network features.
4G like 3G they are all shared bandwidth
so don't expect to see full speed in heavily populated area
if 200 people happened to be connected to the same cell phone tower pumping out 4G, then all 200 people are sharing the same 21 Mbps bandwidth
that means each one will probably be getting in reality 2.1 Mbps at best
of course that's like a worse case scenario, and only if all 200 people are actually downloading heavy content off the network
Sorry about the double post T.T
Three UK are supposedly rolling out HSPA+ this year, they've just announced a HSPA+ capable mobile broadband dongle. (I have no source, I'm lazy, just google HSPA+ UK or HSPA+ Three.)
So that's pretty neat, I'm thinking of getting SGSII with Three, hopefully I'll be able to hop on the HSPA+ when it rolls out!

Number of frequencies that can be used simultaneously on a cell tower has gradually increased from 1 upto 4 today and maybe more later.
So upto 4 frequencies can be used in the same area and each frequency can handle 21 Mbps.
Later there will be phones that can handle several frequencies simultaneously
to get higher speed.
so with this being a hsdpa+ device is it safe to assume that if I were to buy a British sim free version that I can pop in my tmobile sim card would only have 3G speeds?
the fact that is says hsdpa+ and not hspa+ kinda makes me worried that the s2 cant achieve "4G" speeds. (at least the british version)
someone correct me if im wrong but hsdpa+ is the technical term for what tmobile calls 3g and hspa+ is supposed 4G.
Your phone will be able to achieve the highest speed its standards and the implemented network standard allow - the Galaxy S II supports 21 Mbps down (HSPA+) and 5,76 Mbps up (HSUPA). These are the maximum supported speeds/standard, of course the phone can utilize older standards like HSDPA, UMTS, EDGE or even GPRS as well if the local network won't support anything better. If this were a HSDPA+ phone, the maximum achievable speed would be 14,4 Mbps.
4G is nothing more than a marketing term, used by different cell providers for different standards. At this point, it has lost its meaning. (But, yes, by your definition, the Galaxy S2 is going to be a "4g device")

Right I could care less about the 4g wars because none of these network technologies are true 4g. BUT with that being said there is a big difference is real world speed levels between the 2. The GS4G is advertised as a hspa+ and hsdpa+ capable device that is capable of 21mbps. Of course I've never seen anything over 10 but the SGS2 is only being advertised as hsdpa+. So with that being said I guess its safe to say that the SGS2 does not have a hspa+ radio in it. Only an hsdpa+ radio. Correct? None of the docs I've seen show that it is a hspa+ capable device

I am from the UK and can't see how this breaks any trading standard laws. Listing what features the phone actually has does not break TS if the carrier you use it with does not support it. It's no different to listing the phone has quad band even though some of those frequencies are not used in UK. It is fine for Carphone warehouse to list features they know are not supported in UK because:
1. They may be supported in UK in future.
2. Some customers may go overseas and roam to other carriers that do support those features.
But, to answer your direct question. I have not heard about any UK carriers who support HSPA+. This wiki lists worldwide carriers that do support it but UK is not listed: http://en.wikipedia.org/wiki/HSPA%2B.
Simple question: why is Sprint starting to roll out one spectrum of LTE now, and then changing it to a different one later (2013 and on)? Why not start off with the superior one that penetrates walls better to begin with? Any advantages to the frequency currently being built up?
Sent from my PC36100 using XDA
They're starting on 1900 then adding 800 not replacing 1900. Both will be used LTE in 2013. Also they can't use 800 till Iden is off it. IDEN on 800 won't be dead till 2013. Sprint is decommissioning iden towers now in preparation for the shutdown. They are trying to migrate people over to sprint direct connect which uses the cdma network for direct connect.

This site is the best for sprint LTE info...
http://s4gru.com/
okay, this will be fun to try and explain. first of all, my source is this:
http://www.hightechforum.org/low-versus-high-radio-spectrum/ and logic
Data is sent through wavelengths across different frequencies. Basically, the higher the frequency the higher the capacity and the lower the frequency the higher the coverage.
Sprint's WiMax runs on 2500 MHz, which explains the crappy coverage. Verizon has great LTE coverage because it runs on 700 MHz. The reason Sprint went with the higher frequency was probably to meet the demands of an "unlimited data" community because it would have a much much greater capacity than the 700 MHz spectrum Verizons running. This is also why cell providers with much better coverage (ones near 1000 MHz) have to throttle so hard and limit the amount of data usage: because they have much lower capacities (bandwidth) to share with their consumers in those frequencies.
Of course, cell companies dont only use one band of the spectrum. They send it across one low and one high to accomodate both capacity and coverage (i believe Verizon uses 700 and 1400 MHz). What david279 said is correct, Sprint will use both 800 and 1900 MHz eventually, so its gonna have a great LTE network.
So to answer the original question, Sprint was probably confident to launch the 1900 MHz frequency by itself because it is a good medium. 700 and 2500 MHz are at the ends of the spectrum. The best speed results would be more towards the middle. Instead of having great coverage and LTE speeds as low as 1gb/s with the 800 MHz frequency, or poor coverage with WiMax speeds of ~3gb/s (about what i've gotten) with the 2500 MHz frequency, Sprint's settling with good coverage with LTE speeds of Xgb/s (higher than 3, for sure) with the 1900 MHz frequency with coverage later to be improved once the 800 MHz frequency is included
So be ready in 2014 to buy the EVO 4G LTE+, since our phones can't pick up the 800.

Verizon only uses 700mhz for their LTE Network, Not 1400mhz. I believe 1400mhz is a government used band. Also, Sprint cant use 800mhz until the 3GPP and FCC clear that band for LTE use. On top of that Clearwire will be doing TD-LTE on 2500, which will have international roaming compadibility in europe, and yes Sprint did sign a deal with clearwire so they can use that band as well for their customers.
TD-LTE is LTE used on a spectrum that does not have a upload frenquency only download.
FDD-LTE is normal LTE used with a frenquency that has both download and upload.

TD-LTE is LTE used on a spectrum that does not have a upload frenquency only download.
FDD-LTE is normal LTE used with a frenquency that has both download and upload.

1400 MHz is allocated for WMTS (Wireless Medical Telemetry) as primary user, secondary is non-medical telemetry. 1400 MHz was military until 1999 when it was "sold off" to the highest bidder.

And one of the greatest addictions as well. I own a fairly large (though shrinking) collection of all things radio.

No LTE roaming?

Strictly hardware. It's also one of the reasons lte roaming isn't in the cards.

No LTE roaming? Does that mean the EVO 4G LTE can't make or receive roaming calls, or just that it won't use the LTE network for them?
While I'm asking newbie questions, I gather the switch to LTE doesn't make Sprint phones (except the iPhone & one Motorola phone) usable in foreign countries, even countries with LTE networks. Is there any way to make it work overseas (without major surgery)?.
I'm probably going to get this phone when I upgrade, but it would be nice to be able to use it when I travel. International functionality is the only reason I'm still slightly tempted by the iPhone. Well, that and the boffo camera software on the iPhone.

only the lte is limited to the sprint network. you can still use the phone in countries that use the same cdma network as sprint. plug in the country you'll be going to in that link - if it says cdma, you're probably ok. But if international roaming is important to you, this probaly isn't the phone to get (depending on where you go, anyway).
CDMA HSDPA and LTE
How can ATT use LTE Band V2,17,4 Etc. which is 700, 1700, 1900 if other carriers are using those bands. I don't see anybody updating the Wikipedia from day to day with who has what. I see that the Chinese manufacturers are not producing phones for the US carriers except for a few high end phones like the Oneplus One. Is something going on that only Samsung seems to care about, producing a phone with 6 Bands or are the manufactures just waiting for the dust to settle? Don't you agree that a user who buys their phone wants to be able to switch carriers if they move, allowing for more freedom, or what ever reason, should have a phone that handles multiple frequencies. Most of the newer models coming out of china are set for TD SCDMA in their county only and have eliminated WCDMA altogether in those phones. Shopping around is much more difficult because allot of these vendors say little about signal compatibility on the web sites selling these phones.
Guys, I want to buy new HTC Droid DNA, but the seller said, if I used for GSM network its only can running on EDGE only (still locked). any idea how to get full range on GSM Ntework (HSPA / 3G)?
Thanks
+1 to this. I have the DNA in hand but unactivated and have heard mixed things from carriers and online. T-Mobile won't really discuss the refarm of their 1700Mhz to 1900/2100. According to information online they have completed a lot of the refarm so that more GSM unlocked devices can run on their high speed data network. A common denominator from each case is that data constantly switches between low and high speeds. I'm thinking of checking out straight talk or net10 although I've heard negative things about them both and simple mobile. Still looking for a great review of this phone on one of these carriers.

Do it, its fine. Mine has never seen a day of service on Verizon, I use T-Mobile and get H+ all over the place. The fluctuating does occur as they're still refarming towers but it doesn't cause much of a problem.
The refarm isn't for more devices its to move the bands down and use LTE on the 2100 or whatever band instead. It just happens to mean non T-Mobile or pentaband phones gain 3g/H+ ability on their network. Just means phones like the DNA without the higher band support gain faster speeds, or I guess I phones will to, whatever doesn't use the higher bands from at&t networks.

When I said "more devices" I meant the handsets that are only 1900/2100 capable and not 1700 capable. The former is supported by more devices hence "more devices"
It depends on your carrier. On most carriers, like AT&T, it works fine and dandy, on the other hand with carriers like t mobile, it's complicated

complicated meaning what exactly...can you be more specific. Somebody chimed in and said HSPA+ is indeed working on their DNA on T-Mobile. The coverage obviously varies but do you have any information that would suggest it wouldn't work on T-Mobile?
Exactly what subject says.
Can it?

I don't believe so. From what I understand, XLTE utilizes the 750MHz and 1700MHz bands. The Rezound only supports the 750MHz band.

XLTE is just a branding of Verizon's newer LTE network and deployment of VoLTE (Voice over LTE)
The Rezound only supports 700Mhz Band 13 LTE...
Verizon's implementation of VoLTE/XLTE is using 1700Mhz Band 4 LTE...
So, not possible in it's current implementation by Verizon.
Most LTE handsets are capable of VoLTE, technically speaking, but it appears carriers seem to be implementing it in a very non-generic way. In the US carriers (Verizon especially so) are still worried about keeping their LTE networks locked down to their own subsidized handsets only. Implementing a standardized VoLTE implementation could open up their network to third party handsets, and VZW don't like that.
Cool guys, thanks for the info!
I've noticed a huge slowdown of data speeds recently...maybe it's the unlimited throttling thing maybe XLTE implementation, I'm not sure, but I don't like it. (Los Angeles, CA). Just putting it out there, not sure if others have noticed as well.
