I have been trying to find information on this issue on the internet and I cannot seem to find any.

 

1. I have a Google Nexus 5x which is 2xCA capable, it is possible that this device is 3xCA capable with a software upgrade? 

 

2. How can I determine if I am on just Band 41 or 2xCA ? I've been using signal check to see the Band I'm connect to, but I cannot find a way to determine 2xCA connection.

 

Thanks

Nice to see others in indy noticing the great speeds.   Sent from my SM-G930P using Tapatalk

I don't think there is a way tell on that phone. On Sprint branded phones there is service mode

1. No, it cannot be updated to support 3xCA. 

 

2. I do not know how reliable the engineering screen is, but if you dial ##DEBUG# and then click on LTE, it will show you the band that you are connected to as well as the download channel. If you are connected to 2xCA, the SCC (secondary channel) field will be filled in as well.

Hi Dkoellerwx-

 

The DEBUG code worked. When I tried it there was nothing in the SCC area, but I will use signal check and take a look next time it is connected to Band 41. Right now it's on 25.

 

This is also another question, I found this link:

 

http://s4gru.com/index.php?/blog/1/entry-391-psa-carrier-aggregation-now-officially-live/

 

So the 2xCA uses 2 Band 41 at the same time to increase speeds (or 3xCA with newer phones) ? I know the end result is faster speeds, but I'm having a hard time specifically understanding how it works. I actually asked some Sprint employees last time I was in the store as a long shot, but they don't know what I was talking about.

2xCA essentially aggregates two adjacent 20mhz LTE carriers to provide higher peak speeds. Think of 2xCA as sending your data over a pipe twice as wide as regular B41.

That's incredible. I'll have to try it out sometime. I used to have a Nexus 6 which only had access to Band 41. Even here in California I'd still only get around the 20s down, before with an old Galaxy S4, I'd get 8s down. I have noticed my Nexus 5X is getting better reception indoors and is less sluggish than my Nexus 6 :)

What part of California? Parts of California mostly LA have seen small cells Deployed.

I've been experimenting so far the past day, I've been primarily in Orange County although I work in LA County. It appears that a few times it was connected to 2xCA, but the speeds have been around the 30s down. Certainly faster than standard Band 41, but not the 100 mbps that you were getting. I also forgot, but I read something awhile back where there is a limitation due to an interference with Mexico, like similar bands being used or something to that extent. I don't remember what the issue was specifically, but I thought it was competing bands with Mexico and far southern CA.

 

 

Maybe it's the Band 26 ? I almost never seen Band 26, just 41 and 25 unless I go to Los Angeles or north which I typically don't go unless needed.

It is Band 26. There are several (rather lengthy) threads in the forums documenting the International Border Exclusion Zone (IBEZ) where Band 26 and 1x800 is restricted.

Thanks that's what I thought it was. I'll have to take a look at the threads. Last I recall reading which was awhile ago, was that the US Secretary of State John Kerry was trying to working something out with Mexico, or something to that extent, although maybe not anymore.

 

I also recall it affected anything south of LA which would include OC where I reside.

Do we have any new news for band 26 in SoCal yet ???

Actually Qualcomm stated that the Snapdragon 808/810, so long as it has a particular sister chip can do 3xCA.  Most phones come with the required sister chip. 

 

IIRC the only thing is that two channels have to be adjacent for it to support 3xCA.

Fresh off the press

 

3x CA to be enable on some handset early 2017

Not sure how accurate that is...it seems to state that Sprint will be doing B26/B25/B41 aggregation which I do not believe there are any plans for at this time.

LG G5 and v20?  (there is already an update in queue for the v20, but no one has it.  Perhaps that is it? or is this something done through profile updates?)

 Thanks

      Official Tmobile-Sprint merger discussion thread

      By radem · Posted

      Starlink (1900mhz) for T-Mobile, AST SpaceMobile (700mhz and 850mhz) for AT&T, GlobalStar (unknown frequency) for Apple, Iridium (unknown frequency) for Samsung, and AST SpaceMobile (850mhz) for Verizon only work on frequency bands the carrier has licensed nationwide.  These systems broadcast and listen on multiple frequencies at the same time in areas much wider than normal cellular market license areas.  They would struggle with only broadcasting certain frequencies only in certain markets so instead they require a nationwide license.  With the antennas that are included on the satellites, they have range of cellular band frequencies they support and can have different frequencies with different providers in each supported country.  The cellular bands in use are typically 5mhz x 5mhz bands (37.5mbps total for the entire cell) or smaller so they do not have a lot of data bandwidth for the satellite band covering a very large plot of land with potentially millions of customers in a single large cellular satellite cell.  I have heard that each of Starlink's cells sharing that bandwidth will cover 75 or more miles. Satellite cellular connectivity will be set to the lowest priority connection just before SOS service on supported mobile devices and is made available nationwide in supported countries.  The mobile device rules pushed by the provider decide when and where the device is allowed to connect to the satellite service and what services can be provided over that connection.  The satellite has a weak receiving antenna and is moving very quickly so any significant obstructions above your mobile device antenna could cause it not to work.  All the cellular satellite services are starting with texting only and some of them like Apple's solution only support a predefined set of text messages.  Eventually it is expected that a limited number of simultaneous voice calls (VoLTE) will run on these per satellite cell.  Any spare data will then be available as an extremely slow LTE data connection as it could potentially be shared by millions of people.  Satellite data from the way these are currently configured will likely never work well enough to use unless you are in a very remote location.

      will this work for service in a plane?

      T-Mobile owns the PCS G-block across the contiguous U.S. so they can just use that spectrum to broadcast direct to cell. Ideally your phone would only connect to it in areas where there isn't any terrestrial service available.

      So how does this whole direct to satellite thing fit in with the way it works now? Carriers spend billions for licenses for specific areas. So now T-Mobile can offer service direct to customers without having a Terrestrial license first?

      I wouldn’t be shocked if it’s Verizon, too. In my area they have multiple nodes on the same block as full macro sites with mmWave, in direct line of sight.
