Network vision & LTE rollout

This resembles Sprint's EVDO rollout a bit too closely. What's worse, it resembles Sprint's WiMAX rollout too closely!

I've read stuff to the effect that "last time Sprint's WiMAX partner failed them. Today it's different, Sprint is doing it itself.....with three LTE partners." My question is what's so different? Aside from tripling the possibility of failure?

They talk about "Sprint towers", but in reality pretty much every PCS tower is owned and operated by a tower company, not their tenants.

Apparently "roaming will fill in all the gaping holes." To make that happen, Sprint will need to sell phones with a dozen or so bands, from 700MHz to 2.5GHz and every PCS and LTE band in-between. Good luck with making that work.

Finally, where is the money coming from? All the partners? Companies that are big enough to gobble up Sprint each alone?

Let's get real. Right now the competition has Sprint beat when it comes to LTE. How is Sprint going to retain customers while they bring their LTE in very late to the party and in a VERY limited area? I'll bet anybody here $10,000 that when I move back to the Chicago area that I'm not going to find any Sprint LTE outside the Chicago city limits for as long as I live there.

I like Sprint, and by some miracle I've always ended up living and working in areas with adequate Sprint coverage. But when it comes to data, Sprint has always been way behind the curve. Fortunately I'm satisfied with EVDO...for now.

I fear that this yet another Sprint grand plan will receive the tepid response it deserves, and further weaken the company. Possibly into oblivion.
Well 1 big diff is 4g WiMax was Clear Spectrum leased by Sprint. And now Sprint like it has dome in the past is outsourcing but now it's using it's own spectrum and that is a good thing. If you dont think your going to be happy and you think think VZW has got it better then maybe your not understanding the roll out and what it will do for Sprint and you the user. And Sprint was first to the party with so called 4G might not
have been LTE but it was first to market might not have been the best but it was leased from clear. Anybody that undeestands how spectrum works will understand that Sprint not only has the best but it also has then more then most in the US. And the 800MGhz(old Nextel spectrum soon to be CDMA/LTE) is hands down the best and Sprint owns it. Just wait 6 to 8 months mark your calendar if you need to within the next 1 and 1/2 year. You can find me under the same username and I will buy you lunch if it not better :)

How so? One market is barely coming to life (on schedule I might add) and you've made this determination already?

Citation? Lot's of companies use generic tower companies, even the big duo VZW and AT&T. So what? What makes you think Sprint is so inclined to fail?

Actually, the roaming thing is more than possible with Software Defined Radios [LINK] Instead of restricting a handset to certain bands, software filters the bands appropriately, giving the radios nearly infinite range of reception in terms of frequency. What this means, is that it can be tuned to 850mhz, then switch to 1900mhz or 2500mhz on the fly, all while using the same radio, with no extra hardware needed. It's quite revolutionary, and it's going to blow the handset market wide open.

Also, Sprint has a very healthy cash reserve, and a stockpile of spectrum, especially after turning off the Nextel towers and repurposing the SMR spectrum.

I'll bet anybody here $10,000 that when I move back to the Chicago area that I'm not going to find any Sprint LTE outside the Chicago city limits for as long as I live there.

Sprint's LTE rollout is going to surpass the WiMax in terms of coverage, that's a given considering they are using the PCS bands instead of the 2.5Ghz. WiMax in Chicago was actually decent, and outside of Chicago I was able to use it all the way out to Elgin, and south all the way to Oak Lawn. Using the PCS bands, even if it wasn't expanded, the PCS bands will enhance that coverage greatly. Bascially, anywhere you get Sprint 3G EVDO, you'll be getting LTE(eventually).

I just hope Sprint LTE rollout is on schedule and will compete with the best of them. I've been with Sprint for so long(13years) I just figure another year or so is not going to kill me..

I disagree. It's not fair to compare Sprint's LTE build out to WiMax. First, WiMax was handled by their partner, Clear. Where Clear focused their efforts, WiMax was pretty decent (I know they marketed it heavily in Austin, for example). It's too bad they did not get the market penetration they were hoping for, but the success of Verizon's LTE network probably had something to do with that.

Second, Sprint is not that far behind AT&T. Remember that Sprint has switched gears twice in the past year, first from WiMax to Lightspeed LTE, then to their own LTE. AT&T on the other hand has been working on LTE for a while. For Sprint to be close behind despite these direction shifts is pretty promising. Granted, I think a lot of the work they've done was started under the Lightsquared plan so it wasn't exactly wasted effort, but that break-up certainly set them back some.

Third, despite being in third place in the US market, Sprint is still quite healthy (certainly better off than T-Mo). They have strong MVNO partnerships with smaller carriers and their investment into LTE will pay off. They've taken a hit with the build-out and adopting the iPhone, but I think they've made some smart moves.

At least I hope so. I'm a patient guy, but if Sprint's network doesn't show signs of improvement by the end of the year, I'll probably just wait out my contract and switch.
 
Well 1 big diff is 4g [sic] WiMax was Clear Spectrum [sic] leased by Sprint. And now Sprint like it has dome in the past is outsourcing but now it's using it's own spectrum and that is a good thing.
Actually the "Clear" brand is used by a company called Clearwire that is the same company that Sprint partnered with for their mutually owned and operated WiMAX network. BTW, WiMAX as it's deployed by Sprint/Clearwire is not 4G; it's considered "3.5G", just like all of the TDMA carrier's so-called "4G" pre-LTE data systems.


Anybody that undeestands [sic] how spectrum works will understand that Sprint not only has the best but it also has then more then most in the US.
I do understand enough to know that your claim is totally false. The 1900MHz band is way too crowded by everyone, the 2.5GHz band is incumbered by Clearwire, and the 800MHz band that's used by iDEN is going to the police. In reality, Sprint is very spectrum-poor.

And the 800MGhz(old Nextel spectrum soon to be CDMA/LTE) is hands down the best and Sprint owns it.
Wrong again. See above. LTE will be at 700MHz, and Sprint didn't even bid when it was up for auction.

I believe that there are technical reasons why the 700MHz band isn't going to work nearly as well as most people just assume it will. I could be wrong, but time will tell. If Sprint does get its hands on sub-gigahertz spectrum, it will be because it's a white elephant that the other LTE carriers want to dump. I predict that it will ultimately be used for wireless to the home Internet services like Canopy.
 
How so? One market is barely coming to life (on schedule I might add) and you've made this determination already?
As the saying goes, if it looks like a duck, walks like a duck, quacks like a duck... "barely coming to life" doesn't really acquit the decision to repeat the same organizational mistakes, does it?


Citation?
For crying out loud, I'm referring to the posts that I've read right here! You can scroll down; it won't kill you.

:rolleyes: When are you going to stop beating your wife?

If all it took was wishful thinking and a too little knowledge, we'd all be zillionaires. You apparently missed the obvious fact that all radios must still obey the laws of nature. It's all moot because SDR transceiver technology is still in the development stage, but if they went that way, they still have to work with conventional RF amplifiers, feed lines and antennas. Do you have a software defined antenna ready to go to market?


Also, Sprint has a very healthy cash reserve, and a stockpile of spectrum, especially after turning off the Nextel towers and repurposing the SMR spectrum.
So you say. I don't know about Sprint's cash reserves, but the data I can find disputes your claim. If they're so flush, how come they're taking the partnership road after it failed so miserably with Clearwire?

Although you spin the loss of Nextel as somehow being a revenue source, the fact of the matter is that it works the opposite. When you lose customers, revenue goes down, not up.


Sprint's LTE rollout is going to surpass the WiMax in terms of coverage, that's a given considering they are using the PCS bands instead of the 2.5Ghz.
That's beside the point. While you're obviously counting un-hatched eggs, Sprint's track record gives wise people good cause to be skeptical. I hope that Sprint makes a strong comeback, but I'm not going to bet on it.

You have been touting Sprint's little sliver of the completely full 1900MHz band as a panacea, but again the fact of the matter is that Sprint can't break the rules of nature. Sure they have spectrum. But the point is that nobody has enough 1900MHz spectrum to be able to offer 4G data rates and cellphone calls to enough people to make it profitable. There's simply not enough bandwidth to support it. That's why everybody else bought a lot of very expensive spectrum when the FCC auctioned it off over the last decade or so. They're all moving their data services to clear spectrum where they can provide big bandwidth on a grand scale because they can't do it on the 1900MHz band.


WiMax in Chicago was actually decent, and outside of Chicago I was able to use it all the way out to Elgin, and south all the way to Oak Lawn.
With the exception of Oak Lawn, which is at least more than a stone's throw from a major interstate, it looks no better than previous rollouts. When I'm in the Northbrook / Deerfield / Glenview / Wheeling area next month, I'll see if my favorite Sprint store will lend me a LTE phone to see for myself. I'm not holding my breath, though.

And that's the base of my whole point. Sprint covers the areas where it gets a lot of business from less than mobile users, but has Swiss cheese coverage that makes their high speed data services impractical for people with cars, and/or who live and work in the suburbs and smaller cities. I live in Madison, and will be in Lake Zurich next year. Can you tell me truthfully that I'll see Sprint LTE where I need it? I don't think so!


Using the PCS bands, even if it wasn't expanded, the PCS bands will enhance that coverage greatly. Bascially, anywhere you get Sprint 3G EVDO, you'll be getting LTE(eventually).
Great! When will the LTE airave be shipping? :D

I'm perfectly happy with Sprint's PCS service, at least now, after a lot of waiting for the EVDO rollout to become complete enough to be useful. But let's be real for a change. Sprint will be a PCS-only carrier for a very long time, except for a few select markets. The point is that's the same slow rollout that I'm so tired of. The point is that it's no longer acceptable for Sprint to leave its customers perpetually 5 years behind the curve.

Now that it's clear that Wi-Fi and other 802.11 isn't going to do come through for us, it's up to the cellphone providers. My next data dongle isn't going to be like the last one, "good enough for when there's no Ethernet". It's going to be good enough to use for my best home Internet connection if need be. And if Sprint hasn't gotten around to offering that in my neighborhood when others have, then they'll lose out and rightly so.

I'm not a Sprint fanboi; I'm a serious customer who expects service, not hype.
 
The iDEN band is not going to the police.

It's going to be used for 1x Advanced coverage.

Unlike the previous roll-out, the coverage for the entire country to get full 3G service and 4G to all major metropolitan areas is established, documented and being worked, including upgrading 38,000 towers and the entire infrastructure, where things were previously quite slow.

It's called Network Vision, it's been accepted and backed by the financial community, and those in opposition to Dan Hesse (Sprint CEO) and his plans have been recently outvoted by the shareholders.

The engineering layout has satisfied the FCC and watchdogs that when the network is complete, it will be able to support more subscribers than either ATT or Verizon without the service degradations we're accustomed to, and the full national coverage buildout will complete before Verizon finishes even though they started it.

You are welcome to your opinions but please don't pass opinions as facts. Everything I just posted is a matter of public record.

The police aren't getting the iDEN band and infinite frequencies are not required to support Network Vision. I don't know what to call them but those are not facts at all.
 
PS - Sprint has an ownership stake in Clearwire. The WiMAX service will discontinue in a few years and the band will be absorbed into the Sprint infrastructure.
 
I disagree. It's not fair to compare Sprint's LTE build out to WiMax.
Not fair? I'm not a judge at the olympics, I'm a customer. Of course it's fair!


First, WiMax was handled by their partner, Clear. Where Clear focused their efforts, WiMax was pretty decent (I know they marketed it heavily in Austin, for example). It's too bad they did not get the market penetration they were hoping for, but the success of Verizon's LTE network probably had something to do with that.
First off, Clear is the brand name that a company called Clearwire uses to market the WiMAX service that they developed in a joint venture with Sprint. Nobody forced Sprint to do things the way they did, and I'm not interested in excuses anyway. The bottom line is that WiMAX in general has utterly failed to deliver on the promise of high speed mobile data. Or even low speed mobile data. Or even no speed home data. WiMAX is a failure, and every second that Sprint wastes beating this dead horse is another second taken away from righting past failures.

The fact that Verizon and other PCS carriers are two generations ahead of Sprint right now says more about Sprint's failure to act than Verizon's being quick to market.


Second, Sprint is not that far behind AT&T. Remember that Sprint has switched gears twice in the past year, first from WiMax to Lightspeed LTE, then to their own LTE. AT&T on the other hand has been working on LTE for a while. For Sprint to be close behind despite these direction shifts is pretty promising.
I think you're ignoring the elephant in the room, that Sprint has been dithering and working more on slick marketing than they have on sound engineering. I don't see that as a Good Thing at all. Quite the opposite in fact. The bottom line is that Sprint shouldn't be behind; they should not have screwed up so often.


Third, despite being in third place in the US market, Sprint is still quite healthy (certainly better off than T-Mo). They have strong MVNO partnerships with smaller carriers and their investment into LTE will pay off.
Will it? Because right now I can get a LTE phone or data dongle from a competitor today, and be in business. If I wait for Sprint, I don't even know when my city will be on the "to-do" list. If Sprint lost customers like me because of a mass exodus to the carriers who got their ducks in a row on time, Sprint will be in real trouble. And the thing is that scenario is very likely. People are fickle. I've been with Sprint for 12 years because they just happened to have good enough coverage and service for where I've been at the right time. I'm a rare exception. I'd switch in a heartbeat too.


At least I hope so. I'm a patient guy, but if Sprint's network doesn't show signs of improvement by the end of the year, I'll probably just wait out my contract and switch.
Same here. I'm moving back to IL to be closer to my elderly mother. Sprint coverage sucks where she lives. An airave might take care of that. But I have some real concerns about getting data at home. I'll probably be buying a new data radio in LTE, which means not Sprint. If I can't get decent data rates on my smart phone, I'll sell it for what I can get and wait out my contract on a cheap phone with a cheap plan, give that to mom and buy a new smart phone from the provider that provides.

That's business, folks.
 
Anyone in the lte areas seeing any use put of it. I am in Houston but the weather is so iffy that I have not been able to try it out. How about anyone else. Got some speed tests to show?
 
The iDEN band is not going to the police.

It's going to be used for 1x Advanced coverage.
Well the FCC and DHS disagree with you. No offense intended, but when it comes to "Moderator" vs. 3-letter federal agencies, I'm going with the word of the 3-letter agencies. I don't know why they keep chipping away at the 800MHz (and 700 for that matter) bands, but they say they need more for "public safety" and I don't think they're lying.

800 MHz Public Safety Spectrum

Sounds sweet. The problem is that it reads like it was taken almost verbatim from Sprint's marketing releases. The thing is that marketing materials are rarely the God's honest truth. You're free to put your full trust in Sprint's ad agency if you wish. But please don't present marketing materials as if they were factual.


The engineering layout has satisfied the FCC and watchdogs...
What watchdogs?

I don't know where you got the idea that the FCC needs to be "satisfied" with Sprint's business plans, but as a real-life FCC licensed radio engineer I can tell you with authority that that's not how things work in this age of deregulation. Perhaps you meant FTC?


...that when the network is complete, it will be able to support more subscribers than either ATT or Verizon without the service degradations we're accustomed to, and the full national coverage buildout will complete before Verizon finishes even though they started it.
Again it sounds great. But talk is cheap, and Sprint's record with data service rollouts don't support this rosy outlook. I'd be pleasantly surprised if it does come true, but for now it's only a promise with long odds.


You are welcome to your opinions but please don't pass opinions as facts. Everything I just posted is a matter of public record.
With all due respect, please don't insinuate that things I've written is less than above-board. If you disagree with a specific thing I've posted, feel free to challenge it with a quote. But please, no ad hominem.


The police aren't getting the iDEN band and infinite frequencies are not required to support Network Vision. I don't know what to call them but those are not facts at all.
No, those are not facts. But they're your words not mine.

The fact is that that there is no "iDEN band". IDEN is a technology developed by Motorola that has been operating on the SMR business bands after Motorola and others bought out all of the SMR band licenses and devoted it to iDEN.

I'm guessing that you're making your "infinite frequencies" claim as hyperbole to try to put false words into my mouth in an effort to discredit what I actually said. That's dishonest, and you should know better. I hope this doesn't become a pattern.

It is a fact that there is a physical limit to how much data can be sent over any given bandwidth. For example, the absolute limit of phone modems over the PSTN topped out at 56kbps, and even that was more theory than reality. The 54kbps number comes from the net data rate of a digital basic rate interface (BRI) that a POTS phone line ultimately gets turned into. When it comes to radio frequency bandwidth, there's always the chance that someone can come out with another more clever way to cram more Mbps per MHz over the air, although in real world conditions stuff like natural interference limits the usable data rates due to error correction.

Like it or not, but nobody I know of has managed to build a radio system that's capable of supporting hundreds of simultaneous data sessions at hundreds of Mbps (what LTE claims to do) in 20MHz of RF bandwidth. If you can show me a system that does, I'd love to see it. If I do, I will promptly revise my figures.
 
PS - Sprint has an ownership stake in Clearwire. The WiMAX service will discontinue in a few years and the band will be absorbed into the Sprint infrastructure.
From Clearwire Corporation - Investor Relations :

"Strategic investors include Intel Capital, Comcast, Sprint, Time Warner Cable, and Bright House Networks."

Now, after warning me to "don't pass opinions as facts", you're presenting the claim that Sprint will get all of the Sprint-Clearwire frequency licenses. I don't believe that people can see into the future, but I'll overlook that and simply ask what makes you so sure that's going to happen. Can I see a change in ULS that shows a license transfer? Was there an announcement? Because I've read that competitor Verizon has already purchased some of the Clearwire spectrum. Was I been misled?

Perhaps I'm wrong, but I thought that I said that Sprint had an ownership stake in Clearwire, rather than ownership of Clearwire. I think most of us are aware that their ownership is diverse and consists of strange bedfellows, as they say.

I believe that I intended by context that Sprint was planning on using 2.5 GHz band that Sprint's existing WiMAX operates on.

I was aware that bids were in play, Clearwire is a juicy target without a doubt. I hadn't heard yet that Verizon has laid claim to 2.5 GHz, is that so?

If true then I would have to wonder what their mitigation plan would be.

Yes, a stake. I'm guessing they own stock. I don't know how much, though. I don't think any of the mentioned stake holders have a controlling interest (>50%) though.

My understanding is that the Sprint/Clearwire WiMAX thing is a joint venture (like a separate business or something like that). As the project went on, Sprint and others bought stock in Clearwire. This was back when we all thought that WiMAX was going to be the 4G technology. At least that's how I remember it. Now when people look at Clearwire, they see that big chunk of spectrum like zombies see tasty human brains.

As for the strange bedfellows, to me that's a sign that there may be a major shareholder tug-of-war going on about Clearwire's future. Most if not all of those bedfellows have expressed an interest in getting into the wireless Internet business, so I can imagine that there are a lot of differing ideas in play about what to do with that spectrum post-WiMAX. That says to me that Sprint might have a rough time getting the whole kit and kaboodle for itself.


I believe that I intended by context that Sprint was planning on using 2.5 GHz band that Sprint's existing WiMAX operates on.
That would certainly be preferable to that 700MHz band that a lot of the others are rushing to! I know that Sprint has a small chunk in the 1900MHz band that's not being used for PCS voice/EVDO service. I believe that I read that Sprint planned on putting that to use right away. That makes sense, as others with similar bits of bandwidth there are using it for HSPA+ and UMTS data.

The problem is that there's not enough of the 1900MHz band to support all of the smartphone owners that want more and more data. It might work if they could do an overnight switchover and throw in all of their PCS frequencies to make a much larger chunk, and migrate to VoIP for handling regular phone calls. (I believe that's what's going to happen eventually anyway.) That would be quite a feat!


I was aware that bids were in play, Clearwire is a juicy target without a doubt. I hadn't heard yet that Verizon has laid claim to 2.5 GHz, is that so?
Here's a link: Verizon Validates Clearwire's Spectrum Value - Seeking Alpha

And: Clearwire Tumbles After Verizon Announces Spectrum Sale - Bloomberg

If the article is true, Verizon has taken a bite out of Clearwire's valuable spectrum already. If I read between the lines, I'd say that Verizon has figured out that the wavelength at 700MHz makes it tough for handheld phones with built-in antennas (that's my expert opinion), is dumping its 700MHz holdings to companies that haven't figured this out yet, and is trying to acquire as much >1GHz spectrum as it can. That puts a lot of pressure on Sprint. The thing that I'm certain of is that the value of the whole Clearwire 2.5GHz band is like a holy grail for cellphone companies trying to massively pump up their wireless data capacities.


If true then I would have to wonder what their mitigation plan would be.
I dunno. Maybe Sprint lawyers might find something their agreement with Clearwire that gives them dibs on the spectrum. That could drag through the courts, but would be worth it. One can hope.
 
From what I have read, they are saying it will be turned on tomorrow and announced on Monday. No sign of it in Austin as of yet.
 
From what I read on s4gru Austin is not really in the area it is more like Waco. Surprised the crap out of me. Waco really?
 
We have the same recollection of the original Sprint / Clearwire deal. Sometime later, Sprint did buy some significant block of stock as memory serves, but I don't recall the fallout in the financial community, and after that, I mostly stopped following that part as too little, too late from my point of view.

I may be mistaken, but I thought I recalled that the FCC had ok'd Sprint's application to expand LTE services to 800 MHz, but I don't recall the band or bands under consideration.

I did read an assessment by one insider, off the record as I recall, that should the grand unified cell service theory of Sprint come true with services on 800/850 MHz CDMA (I know, those are colloquial, not true frequencies) and 800/1900 MHz LTE with some sort of bridging at 2.5 GHz, then their next step would be LTE Advanced, the final part funded by an influx of subscribers, justified by the rationale that they would be too attractive for consumers to pass up.

I'll have to come back with links for any of the above later, I'm on my phone at the moment and tending to several things at once.
 
I've been seeing random moments where the phone says 4G instead of 3G but it doesn't last for long. Once I try using the internet it switches back to 3G. I'm in the Dallas area. Garland to be specific.

Yes, it is too late for Sprint to wrest control of Clearwire away. But maybe they can use the terms of their joint venture into WiMAX to keep others from decimating Clearwire's spectrum. After all, Sprint still relies on it for their own WiMAX service. If WiMAX suddenly vanished, Sprint customers with "4G" phones might sue and/or leave en masse over the outage, which would be very bad. I hope that Sprint can and is protecting its interests that way. If so, it might be a way for Sprint to keep its fair share of data spectrum, which is going to be vitally important. Having that spectrum on the coveted 2.5GHz band, that's bonus. :D


I may be mistaken, but I thought I recalled that the FCC had ok'd Sprint's application to expand LTE services to 800 MHz, but I don't recall the band or bands under consideration.
The deregulated, post 9-11 FCC has been a mess. First they let "the market" decide things that are more engineering matters than business. Then they started selling spectrum for a profit. :rolleyes: I still don't fully understand why they had to swap the old (D)AMPS band with the 800MHz SMR and public safety bands, but in the process they gave the lion's share to public safety. Now they're chipping away bits and pieces of the SMR band again, claiming that it's needed for national security, at the same time several new public safety bands taken from old TV spectrum came on line. WTF are they using it all for? On TV the cops all use cellphones. :confused:

All I know for certain is that every once in a while, out of the blue the FCC reallocates a little more of the prime business and ham bands for their mysterious public safety juggernaut. Not very thoughtful at a time when public safety seems to have more than enough and mobile data could really take off if they had the room.


I did read an assessment by one insider, off the record as I recall, that should the grand unified cell service theory of Sprint come true with services on 800/850 MHz CDMA (I know, those are colloquial, not true frequencies) and 800/1900 MHz LTE with some sort of bridging at 2.5 GHz, then their next step would be LTE Advanced, the final part funded by an influx of subscribers, justified by the rationale that they would be too attractive for consumers to pass up.
Actually even the FCC calls them "the 800MHz band" and "the 850MHz band". I think that they can't remember which service is where after the swap either. ;)

I see that the new-old AMPS bands are still divided into A and B uplink and downlink blocks, just like in the '80s. Since CDMA doesn't need separate frequencies like that, they could merge it all into one contiguous band each for and B. So it would be 806 to 849 and 851-894. That's two blocks of 43MHz bandwidth!

Since the old AMPS frequencies were used most in rural areas where customer density (and thus profits) were less, they can probably re-use the rural antennas and some of the radio equipment to deploy CDMA2000, giving EVDO service to the most remote areas. In urban areas these bands could be used to provide legacy EVDO support while LTE rolls out above 1GHz. Provided that existing phones could be adapted by reprogramming, that is. Old phones that have (D)AMPS radios down there are obsolete anyway.

For readers who don't know, EVDO uses the same in-band channels that are used for voice, and multiplexes them for data. The thing that made EVDO the data king was that a virtually unlimited number of voice channels could be added to a data session, with a corresponding increase in the data rate, while EDGE had a fixed number of time slots it could use. The bonus for having a large contiguous band is that even more channels could go into a data session for even greater Rev.C data rates.

In urban areas they could set up the systems to use the 800/850 bands for mostly voice calls. If that works out, they could repurpose the 1900MHz CDMA channels to LTE sooner. They could still leave a few physical channels for legacy phones during this time. The beauty of it is that Sprint could get more LTE faster, using simpler phones, and without needing the 2.5GHz band desperately for LTE. That way they could afford to keep WiMAX as long as they say they want to with less risk, and they could out-wait other 2.5GHz band suitors to boot. Sweet! :D
