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.

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.

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.

So, we've all seen Big Red's LTE capabilities and it's extremely impressive. Anybody care to speculate on what Sprint's LTE will be like, considering the much higher frequency it will initially be running on? Think about penetration (no homo), range, speed, and the never-ending rumor of potential bandwidth caps/throttling.
Speed, no clue. Penetration obviously won't be anywhere near as good until they get it on the iden frequency. 1900 seems only a pinch less sucky than Clear's current frequency to me.
If I understand right the iden frequency is 800mhz? I thought sprint was only going to use this for voice calls?

Sprint had commitments for iden till 2012, this year, they can shut off the nextel iden network and roll out LTE on the 800mhz frequency this year and likely will do so with that new hybrid box they have been working on. This won't go in all at once, they will roll it out in stages by city and will likely take two years to get it mostly out and another 5+ to hit 95% of market coverage converted.

From what I was told, Sprint is building boxes that can push LTE and CDMA on 800 and 1900. How Sprint actually allocates the bandwidth I have no clue but it looks like they are leaving it open for any combination of the two, my guess would be that it depends on load.

From what I was told its going to be dependent on the tower location what freq will be used ... In Areas where towers are closer like major metro areas they will use 1900 in more rural areas the will use 800 because the signal will travel further and you can cover more with less towers...but the hardware is going to have all the same in every tower....as redundant backup also....

Signal wise it should be roughly the same but from what some of the LTE testing has shown is that the performance degrades much more with LTE than it does with EVDO over the signal.

Actually, when it comes to metro areas, places like a big city with a large down town district, 800mzh overlay with the 1.9 is the ultimate solution.
800 will penetrate deeper into the buildings and overall give a better in building coverage. So densly populated areas would be a great candidate for both 800mhz and 1.9mhz.
Also there is only so much spectrum that each carrier owns in a given location. So if loading is an issue, they can offload some of the usage to the 800mhz spectrum if or when necessary.
Whatever happened with the rumored upgrade to EVDO Rev B?

Sprint has very little Spectrum in 800MHz compared to the others.....If I were to guess any off loading will be to Clears 2.5GHz which is supposed to have over 5k sites up by next June if i remember correctly...

Just wondering why Sprint doesn't continue to use Wimax on devices like the E4GLTE? With GSM carriers they're incorporating 3g along with HSPA+ and rolling out LTE (AT&T), wich is great because between all 3 options you should be able to get some awesome data speeds pretty much all the time. Wouldn't it be great if you lived in a Wimax area with LTE you could fall back on one or the other depending on wich had a stronger signal. Im just wondering why Sprint is not going this route. With all of the reviews of the E4GLTE the one resounding fact is that there is currently no LTE anywhere and 3G speeds are horrid. It seems like keeping Wimax and using it when you can would have been a good option, at least temporarily. Any ideas?

Well...umm...
1. Wimax requires a different radio. LTE is built into the CPU, so you'd have to have a separate chip for wimax.
2. Wimax sucks. Its only claim to fame is that it was the first 4G available. Building penetration is crap.
3. Having both in the phone would cause power drains like you wouldn't believe.
4. Sprint is shutting down Wimax to focus on LTE. I imagine the expense of keeping both running is pretty high.
Just sit back and be patient. LTE will be there soon enough. Or stick with your current wimax phone and wait until you have LTE to upgrade. If your main reason for the upgrade is LTE then you should reconsider your options.
Remember HD DVDs? and BluRay? Which one is still around?
Also, Plasma, DLP, LCD, LED technologies in TVs. Its a 'technology war' thing.
WiMax and LTE were two technologies like this. LTE won as BluRay did and to keep up, Sprint has to rebuild their network. Also, the reasons stated above in smw6180's post.
I actually could care less about which one I have as I'm on wifi most of the time. This was truly "Just a question". But isn't HSPA+ a dead technology but its still being included into GSM devices even the ones with LTE. Im just wondering why it is and Wimax isnt. And where I'm at Wimax is awesome I get anywhere from 4-8mbs when im on it.

GSM carriers include 3g, HSPA+, and LTE because HSPA+ is an extension to 3G, using the same radio. Therefore there are still only two radios in the device: WCDMA (which is 3G with HSPA+) and LTE. Sprint's doing the same thing - their equivalent is having 1xAdvanced, EVDO rev B, and LTE.

No, HSPA is in its own class of speed, CDMA doesn't have anything close to it. And it's not like sprint's network could handle much anyway, since there's plenty of dirtbags abusing the Unlimited service.

First, because the phone is at least $70 more expensive on T-mobile's store.
Second, even that version of the phone does not do HSPA+ over 1700 MHz (it's actually the same N7100 you see everywhere). The trick is, T-mobile is supposedly switching all of their 1700-band HSPA+ towers to 1900 band, partly in preparation for their LTE rollout and partly because that's the only way they'll be able to get the iPhone to work with their network, but they haven't gotten it done everywhere and I'm concerned that I'll plop down ~$600 on a phone that only gets 2G speeds at work.

You had me worried so I looked it up. According to the news sources I found, T-Mobile is converting it's 1900 2g towers to support HSPA+. So for the present the current 3G network is not in danger. I suppose my Amaze will continue working for a while!

Almost every tech news site that discusses the 1900 band refarming mentions that the reason is to re-deploy 1700 for LTE (that, and to get the iPhone running on T-mobile because Apple outright refuses to make the iPhone pentaband for some reason). It's a fairly easy Google away.

I hope the frequency change will improve the signal's ability to penetrate into buildings where I work. My service is magnificent, except for at work. There, it is positively dreadful.
Sadly, looks like it's a moot point anyway, til I upgrade to my next device.

Right now Verizon runs on 750 mhz which which is very good at penetrating buildings. The new freq they are moving to is 1.9 ghz and 2.1 ghz which will not penetrate objects as well or travel as far through open space. The higher the frequency the bigger impact objects, trees, and distance have on your connection. But higher frequency also allows for more throughput so look for better LTE speeds

Personally I think Verizon is crazy to be giving up 750 MHz spectrum to go with 1.9 ghz and 2.1 ghz spectrum. I think they're doing it because you can place more towers in closer proximity using higher frequencies than you can using 750 MHz. The signal traveling further in 750 MHz also causes you to interfere with yourself, so by going to higher frequencies they can place more towers, which enables them to distribute the bandwidth across multiple towers.
So look for higher speed capabilities, and also more consistent speeds. It should improve the reliability if they are in fact going to put up more towers. Just don't expect to get much better performance than ATT or TMobile inside, since these are similar frequencies to what they run on.

They're not "giving up" anything. The AWS bands will be an overlay in congested areas.
They're giving up frequencies in the 700 MHz band that they acquired in 2008 in an auction. I'm not saying they are doing away with 700 MHz altogether, but they are giving up channels in the 700 MHz band. Hopefully the hand off between their "AWS" and LTE network (aws just being the license name of the frequencies) will be more seamless than the hand off from 3g to LTE. Otherwise we will have 3g, LTE, and "AWS" that our phones will search for and need to jump between. Every time you enter a building you'll drop AWS, try to get LTE, may or may not get LTE, then drop to 3g...
Anyone that used Sprint WiMAX can tell you how bad higher frequencies penetrate buildings.

I hope the frequency change will improve the signal's ability to penetrate into buildings where I work. My service is magnificent, except for at work. There, it is positively dreadful.
Sadly, looks like it's a moot point anyway, til I upgrade to my next device.

They're not "giving up" anything. The AWS bands will be an overlay in congested areas.

GOD I hope they don't drop the 700 series down the road. I went with them strictly for the building penetration (I work in a hospital). T-mobile would give me zero signal indoors.
I can't see them giving it up completely until at least 2 years after they stop making phones those radios.

They're giving up frequencies in the 700 MHz band that they acquired in 2008 in an auction. I'm not saying they are doing away with 700 MHz altogether, but they are giving up channels in the 700 MHz band. Hopefully the hand off between their "AWS" and LTE network (aws just being the license name of the frequencies) will be more seamless than the hand off from 3g to LTE. Otherwise we will have 3g, LTE, and "AWS" that our phones will search for and need to jump between. Every time you enter a building you'll drop AWS, try to get LTE, may or may not get LTE, then drop to 3g...

They're giving up lower A and B block licenses that they never did anything with anyway, due to the antenna design issues. Their existing 700mhz footprint will be entirely unaffected.
I have to assume that cross-band LTE handoff is much more robust than failover to 3g. It has to be, if they're expecting to use this network as the basis of VoLTE.
Its all in how its handed off. If you think about it as going between 2.4 ghz and 5.8 ghz on a router using the same technology just different frequency the handoff isn't smooth at all. Time will tell.

So jodell..your saying that the DNA does have the proper radio?what can of speed can we expect?
I'm glad I have hung to my unlimited
I'm not saying we have the right radio, I'm just saying we have the right antenna. Our antenna is tuned for the right frequency, but whether or not our radio can demodulate LTE at those frequencies is a whole different story. I don't know enough about cellular wireless technology to tell you for sure.
Also, I believe other carriers are already running close to 2ghz LTE networks, so I would expect to see speeds similar to theirs. I think ATT, TMobile, and Sprint are all licensed for LTE at around 1.7 ghz - 2.1 ghz
Personally I wouldn't buy the first phone capable of running between the two different bands until it's proven itself. And I hope our phone isn't capable of running in the new bands.
Anyone know if our phone is capable of doing this? Verizon just rolled it out in Seattle (where I'm at) and my friend on his Note 3 had to go into his "Service Mode" and enable it manually but is getting 78megs down and 26 megs up (first test in a congested area). Here's a link to the article he had to read in order to enable it: http://forums.androidcentral.com/ve...enable-band-4-aws-sm-n900v-requires-root.html
After doing some searching it looks like we're SOL. Can anyone confirm? It's been a while since the last post in this thread so I am assuming things may have changed since this last post.

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?
