They'll probably have to do something like Apple's dynamic antenna for all of the antennas in each phone soon.
-
Would contiguous carrier aggregation take up 2 antennas? This could be difficult, as it takes an antenna away from being able to do carrier aggregation on other bands or other parts of PCS, also probably the cause of the battery drain.
-
I think that the old phones will still be able to access the subcarriers in the lower half of the 10x10 block while newer phones will access the subcarriers in the whole 10x10 block.
That would be a really neat inclusion in the LTE spec. I did a search to find out more about this, but no luck. Do you have more information on how this would work, maybe a spec sheet, or keyword?
The closest I could find would be Intra-band Contiguous Carrier Aggregation, but it seems like this could be done with 2 5x5?
What is the capacity increase of 1 10x10 vs. 2 5x5 with carrier aggregation? I don't care much about top end speed increase, but that seems worth investigating too.
G Block: 1910-1915 MHz and 1990-1995 MHz
Proposed H Block: 1915-1920 MHz and 1995-2005 MHz so they would definitely be contiguous.
-
If half of the 10x10 is outside of what existing phones support then I don't see them being able to use any of that spectrum. Any phones that don't support H probably wouldn't work on that spectrum at all. That's like all LTE phones sold in the first 2-4 years. But my understanding is limited.
-
I just don't see them traveling all the way out to northern Minnesota or really anywhere outside the cities to add a 5x5 carrier for PCS H.
-
Well to continue that, Sprint probably wont visit a lot of these towers again for 10 years for an upgrade like this! Thank goodness they are installing 800 on the first go around! Any new spectrum upgrades would probably only happen in major congestion areas.
-
Careful, you're starting to sound like wiwavelength. Seriously though, can't those panels/RRUs do H? I mean it's so close!

AT&T Hoping to Snag WCS Spectrum in San Diego -Phonescoop
It's only a matter of time now before they come for Sprint's WCS spectrum.
-
Enhancements/Fixes
- Inclusion of SWYPE keyboard
- Improved LTE connectivity
- SMS Messaging improvements
- EAS sync improvements
"This update, which is build number L710VPL13 for those who like to keep up with that sort of thing, is rolling out in stages beginning now."

Hopefully the H auction waits as long as possible until Network Vision revenue comes in and Sprint can actually pay for more spectrum.

I think Sprint has the better argument. Let's get some of that H! Dish hasn't even started deploying anything or announced a partner/vendor, this couldn't delay them that much.
-
CDMA voice is part of Sprint's long term vision. It's not going anywhere for a while. One of the main reasons is that it can provide HD Voice quality on a sliver of spectrum compared to gsm, which is clogging the pipes for ATT/T-Mobile right now.
Also, Sprint really needs to finish Network Vision, with the 800 mhz LTE deploy, to see exactly what their LTE footprint looks like. They need to make sure that coverage would be ubiquitous enough to offer voice over LTE, and be able to drop back to CDMA if coverage is not there. They don't have any LTE roaming partnerships with other national carriers and LTE doesn't travel as far as CDMA 1x by a non trivial distance. I would like to see them wait on VoLTE, until Verizon has worked out all the bugs.

It's just normal
Quick question, I'm deciding on whether to switch to sprint or not and this all depends on their 4g lte rollout. In my area I see numerous voice and data upgrades in the next 6 months to the cellsites on network.sprint.com. Does this mean LTE is being deployed here? or could it be just a normal update?
It's just normal "band-aid" updates. Iowa will not be getting LTE or Network Vision in the next 6 months. It is not part of the first or second rounds of Network Vision..
-
My guess is that there's a few reasons. Sprint had less spectrum in Chicago (thinking pre G block). Chicago has a lot more people. Back haul has taken forever. KC is home base for Sprint, Chicago is not the only crippled Sprint network out there.
-
Cheese and rice! You can't make this stuff up! If Sprint announced Chicago launched on the 21st, S4GRU forum space would probably fill up.
Ok actually read the article. Looks like they are going to do what S4GRU has been asking for all along and making the sites discoverable. They even have a term for it. "pre-launch mode"

"So on AT&T, iPhone will fall back to HSPA+ while on a phone call." NICE More reason to keep that HSPA+ network chewing up spectrum for years to come.
-
This is what happens when you have a limited number of SKUs for every market in the world. You have to make compromises like this. The Galaxy S3, EVO 4g LTE, and Photon Q were all made specifically for Sprint's network and exactly the needed antenna design was put in them. With the additional LTE bands going into use for all of these networks, Apple will have to follow suit with their next phone and customize for each carrier.
Unless of course some magical technological changes happen in antenna design.
With the reasoning that this user came up with, however, At&t wouldn't be able to do simultaneous LTE and calling either, until they implement VoLTE or something similar.

It's SVLTE guys as Robert pointed out. SVDO is Voice/EVDO. SVLTE is more likely to be supported as there is not an extra cost as there will already be separate antennas for 1x/evdo and LTE.
Also regarding HD Voice, as you've probably seen the Iphone 5 does not support Sprint/CDMA HD Voice. This is due to the fact that the Iphone does not support the EVRC-NW codec. They do support the gsm AMR-WB HD Voice codec, however.
I wish that Sprint's HD Voice used the AMR-WB codec, but Qualcomm probably doesn't support that over their cdma chips. Another nice option would be for ios to include support for EVRC-NW.
Maybe VoLTE will bring AMR-WB to Sprint, but VoLTE might be a long ways off.
-
The Iphone probably wont have all the connectivity issues of the EVO.
-
I said this in the other thread, but I think it's huge that the At&t version lines up perfectly with T-Mobile's re-farming. I'm sure they will get it when they actually launch LTE.

Apple's spec page for the iPhone 5 has been posted, revealing that the phone will come in three different radio configurations, each offered in three different storage capacities - 16, 32, and 64 GB - for a total of nine variants. One model will be exclusive to AT&T, supporting 4G LTE in their 700 and 1700 bands. The model for Verizon and Sprint will support CDMA and both carriers' 4G LTE bands, plus three other LTE bands used overseas. The CDMA model will also support EVDO Rev. B. A third model will support European and Asian LTE bands. All three versions will support quad-band GSM and quad-band WCDMA/HSPA+ (850/900/1900/2100). None of the versions will support T-Mobile's USA's HSPA+ network in the 1700 (AWS) band. Nor will any version support band 12, the lower-700 MHz band used by regional carriers such as U.S. Cellular for 4G LTE service.
Seems like the At&t variant will support T-Mobile AWS LTE (band 4) and PCS HSPA+ , wont it?!? Seems like T-Mobile should get a version or be compatible after their re-farming if that is the case, this is a win for them.
-
Non Iphone users will definitely have their salvation on 800/2500 with one SKU... Wonder if it i supports AWS-LTE for Verizon/T-Mobile, probably not.

I was thinking of something where each antenna could support more than one band.
