Lte

Lte requires sim cards right? So hopefully after sprint makes the upgrade to lte, we'll be able to buy sprint phones and use a sim card from any of the big 4! Dream come true in america, emirite?

Not really...AT&T and Verizon are both going FDD-LTE on the 700mhz band...Sprint will get TD-LTE on the 2.5ghz~ range....
T-Mobile is going on their own HSPA/LTE hybrid variant...
So while Verizon and AT&T phones might be interchangeable (assuming they dont lock them say via some other method)..Sprint and T-Mobile will not be part of that...

Well its not impossible for a device to support both TD-LTE and FD-LTE on a single chipset..but we would then have to buy international phones..cause knowing carriers they either won't include those bands or lock them :/

700mhz is better building penetration over 2.5ghz..BUT how TD-LTE is allows carriers to use more spectrum...right now AT&T and Verizon plan to run it in 20mhz worth of spectrum each..realistically speaking that would constrain quantity of users/amount of data...(hence the tiered data)
Sprint right now though is running wimax in 10mhz of spectrum though..and could run it in 30mhz if they please..
So realistically speaking its easier to run TD-LTE as more spectrum is available in comparison to FD-LTE running at the limited 700mhz spectrum..while 700mhz spectrum though will offer betetr building penetration/signal

So its basically the 3g story again lol sprint has the better and same constant speeds no matter the load, but the signal won't be as strong lol. I can deal with that
And buyingunlocked international phones isn't bad...my friend only uses unlocked ones and they always have extra features compared to a branded one... and all he would have to do to activate it was slide his sim card in it. I hate how att/tmo users can effectively use any phone they want...I want this freedom with sprint/verizon

Sprint's LTE will act like the current Wimax implementation because it'll be running at 2.5ghz. We all know how spotty it is, especially when indoors.
Verizon and AT&T, at 700mhz will act their current 3G service because it's very close to 800mhz. They'll probably have an easier time getting better coverage because they know the 800mhz frequency.
Personally, I'd rather be at 700mhz for LTE, at 2.5ghz, you lose to much coverage and I'm sure Verizon already has the limited bandwidth figure out. If they didn't they could be throwing billions of dollars down the tube.
I can't wait for Verizon handsets to hit the market. My Sprint contract just expired so I'm looking to jump ship.

Well yes and no..thing is most international phones dont have the AT&T 3g band and don't have AWS (most common t-mobile 3g band) on same band as T-Mobile

As I said its spotty because right now..
1) sprint is using only 10mhz of spectrum...
2) They are doing minimum deployments..aka the need mroe towers but being cheap...

Yes its called Tiered Data plans...not fun...

Anyway, wouldn't the first crop of Verizon LTE phones still rely on 1x for voice and 3G EVDO/LTE for data?
So basically we're going to have a scenario where a Verizon LTE phone would be something like this CDMA 2000 1x/1900mhz EVDO/700mhz LTE,
and
an ATT LTE phone might be like Quad band GSM/GPRS/EDGE/UMTS 1900 (HSPA?)/700mhz LTE?

My 2 cents vzw & att are double what we pay for a premium phone service on sprint and not unlimited anything also have bad coverage. They nickel & dime the crap out of you on top of it. Also wimax has voice calling capabilities not just data. Lte for some reason can only do data. So maybe some new features with voice calling with wimax.

Wimax for voice calling? I find that scary. In its current iteration its flaky enough just for data. I shudder to think how crappy voice calling would be on it. They seriously need to build it out a ton more. I walk in my house signal disappears....not encouraging.

Sprint is working on making a seamless radio..aka unlike now where you need to enable/disable 4g it would work in a way that even if 4g is disconnected your session would not be interrupted...same for calls..

LTE doesn't require a SIM card...Verizon is CDMA

True 4G on our Atrixs

Just a thought... but if verizon was willing to upgrade all the xooms to 4G why doesn't AT&T do the same for our phones when they roll out their LTE? Just a thought since having a powerful device (even though its crippled) with awesome speeds would be nice.

it's not that simple. there's no magic 'switch' or replaceable part that enables LTE.

That and the fact that the Xoom is a Google flagship device.

Anyone who buys the Xoom now that wants LTE later has to send their device into Moto to have the hardware upgraded to support LTE

It's quite clear that the Xoom was designed with upgradability in mind while the Atrix wasn't. Actually if I remember correctly the Xoom has an open expansion slot. I'm sure ifixit would have the information. I know however that the Atrix radio chip is soldered in place. Realistically though, AT&T has no active LTE network and won't until probably after the T-Mobile acquisition is complete - they have started they want to use the AWS band for their LTE network. And by then we'll all be lining up to buy the next high end phone. Hexacore anyone?

Well, they're using T-mo's bands to help expand their pre-determined LTE rollout from 80% to 95%. They also want to use T-Mo to help support their H+, but AT&T already had spectrum set up for their LTE before this acquisition

When LTE on AT&T is out you are going to have already your next Android phone with quad core processor;-)

Wimax/LTE chip?

4g wimax/ LTE both?
Got the epic a few weeks ago and the display sheet for the phone showed wimax and lte but the evo didn't. So I asked the sale person if it is a typo and he said no. The phone would need just the software to enable the LTE. He asked a co worker and he said the same. Does the epic actually have a wimax/lte enabled chip or are they just going by a typo? Was just wondering as I know sprint is looking at LTE now.

Highly doubt it...there isn't much of a way to get a sim card in the phone...

A combination flustercuck of a typo and reps who don't know what they were talking about.
Epic has no LTE hardware.

I figured they were stupid. I figured if they really put both chips in here the cost would be more kinda like a global phone. Would be cool though if they would and allowed us to use verizons lte just like roaming on the 3g side.

Lte doesn't need sim cards and he didn't say gsm say your response is not valid. I'm not 100% on this but all sprint has to do for lte is switch out very minor things. The only difference with our phones is the spectrum it is looking for. So since we have 4g and maybe the software can make it lte. Its possible I think.

Never. Different spectrum used and even then ATT and Verizon have no reason to sign roaming agreements when they are each others biggest competitors.

Uh Huh...show me an implementation for LTE that doesn't use a Sim card for network authentication.
I mean GSM doesn't "Require" a sim either, that can be spoofed with hardware...just sayin.
I mean at least in for me, I have put 32 Sim cards in Verizon Pantec UX260 USB Aircards for some reason....

They can configure these phones however they want. We have 4g with no sim card. 4g is almost exactly the same thing as lte just different frequency that's all.

Ummm no...the entire protocol is different.
there are currently 3 popular 4g implementations.
HSPA+ with Extended Backhaul (ATT, Tmo)
LTE (VZW, Metro, non national carriers, EVENTUALLY ATT and Tmo on different freqs)
WiMax (Sprint)
The only thing these share is the 4G monicker. The technologies are enitrely different, the protocol is entirely different, the modems are entirely different.

I saw. Some company announcing a dual lte/wimax chip about 6 months ago. Since the modem controls these chips it isn't a far stretch to have software that will switch modems as needed.

According to a seemingly knowledgeable manager I met with (he was down with rooting and xda lol) wimax is compatable with lte with a software update. But, honestly I doubt it.

That's what the 2 best buy employees said. Wasnt sure as most there are there for the money and know nothing. I asked if the evo had the LTE chip too as it wasnt listed and they said no but the Epic did. I couldnt imagine sprint leaving people hanging in today's phone battles. I will have to ask a store manager if they work there and see if they have any knowledge of it yet or if we will be able to roam. I thought LTE was near the same freq. for sprint and verizon with sprint just having the larger freq bandwidth due to LTE WIMAX.

This came up back when WiMAX was first being introduced. I remember the CEO for Clear said multiple times that the WiMAX infrastructure was software "swappable" to LTE. It wouldn't surprise me if phones were the same.

it's a completely different network to set up and unlike metro pcs, att has a whole nationwide network to think about rather than just a few metropolitan areas.

Metro uses Verizon towers IIRC.
So it's possible they have a lease deal for LTE usage.

MetroPCS LTE is horrible! I tried it and got the ATT Atrix at the same time. A speedtest showed only getting 1.5MB over Metro LTE and im getting over 2MB on ATT HSPDA+ without backhaul....

Why is my LTE device displaying as HSPA+?

Hey guys. I Have a Samsung Galaxy Note 2 (SGH-I317M) and for some reason it fluctuates between HSPA+ and 3G signals rather than LTE. The device is originally locked to Rogers but I unlocked it and am now using it with MTS. I am running on jelly bean 4. 1.2 and CleanRom 4.0.5. Anybody have any ideas as to why I'm not getting LTE?

Yes I'm getting fast speeds but I can't help but wonder why this is happening. I mentioned that I'm with MTS so I'm not sure if that's what you're looking for. I live in Canada so it's probably not familiar to you. They just started carrying S3's which are running on their LTE network and they show 4G at the top of them when activated rather than HSPA+.

It is either the towers or your phone isn't compatible with the bands of LTE (there are multiple bands like there is with UTMS).

I'm pretty sure it isn't the towers cause my friends iPhone 5 is running off LTE and he live about 5 minutes away from my house. I've also been at distances one minute away from his house and did not pick up LTE then either. I don't know much about bands or frequencies but my carrier just launched the Galaxy S3's and they run off LTE and I'm assuming the Note 2 has the same hardware. S3: 700 (Band 17), 1700/2100 (AWS) MHz , Note 2: 700(band 17) 850 AWS 1,900(band 2). I'm clueless as to what those numbers mean but i'm guessing the important thing is Band 17, right?

Try going near his house then. Or have you checked the network settings? You may have to flash something.

I have to no avail. I had a friend try to help me out over the phone with network settings and his phone appears to have a setting that mine does not. When he goes into settings > wireless and network more settings > mobile network there is an option for him to toggle between LTE, HSPA+ etc. My phone doesn't have that for some reason. All that's listed is Mobile data, data roaming, Access point names, and network operators. Nothing to toggle between networks, which is probably what I need to enable LTE. I have no idea why that setting would be absent from my device. My friend was using an S3 on the same operating system as me btw.

From what i can tell it's the frequencies . The frequencies your device have seem to be different than the frequencies the s3 have on your carrier. If it's not that then you can check your apn settings.

What model is your phone, and what model is his phone. You said you brought your phone from a competing carrier who is likely using alternate frequencies that your phone might not be picking up either due to hardware or software limitations. Without knowing the hardware, and where it came from in the first place, we can't figure out what frequencies your phone is looking for and can't answer your question effectively.

download an app that will show you what is the type of connection you are actually on.
I think that maybe its the matter of incorrect icon.
