B25 CA?

As I was reading the iPhone 6S's supported intra-band CA band list, I noticed that 25-25 was on it. This made me wonder - in the markets that sprint has an additional B25 carrier, do they plan on aggregating it with the G-Block carrier to essentially deliver the speed of a 10x10 setup?

Sprint's Midband B25 is getting less and less relevant.  More and more of its traffic gets moved to B41 every day.  The more that gets off, the better it performs.  Additionally, Sprint is adding more

No.

Why wouldn't they want too. I don't know what the technological downsides would be if any but otherwise i don't see the point in not doing it. Its another way to boost speeds

Sprints PCS equipment is not capable, yet.

Ah got it. I did read something about band 41/25 and band 41/26 CA. Is sprints equipment able to to do and if so does sprint have an e.t.a on when

The technology is not even done in the developement phase. Nevermind having the hardware for it.

It's not a want thing. The release of LTE they deployed B25 with does not support CA. It will take an upgrade of the B25 network to do it. And with the other priorities on the front burner, I don't see them going through this trouble any time soon.

to increase the bandwidth for band 25 doesnt need carrier CA. Sprint has 10x10 on band 25 in a couple of cities ive even heard that chicago might get it. Sprint should do CA where its band25/26. dont see that happening tho.

10x10 nationwide would require shutting down a large chunk of the CDMA network, which Sprint isn't ready to do. Sprint currently cannot do CA with B25+B26 because that CA must be officially certified first.

I personally think B26 should not be aggregated with any other Band. In order for a user to use CA on B26 and any other Band, that means they could be using another Band altogether. And no one should be on B26 except for people who have no choice because they have no other LTE signal available. B26 is wasted to aggregate. It will never be useful to anyone else who can't use anything but B26.

 

B25 carrier aggregation could be useful with other B25 carriers. When Sprint can do this in the future, it will be useful.

 

However B25+B41 CA is also unnecessary and wasteful. Because if someone is in range of B41, there is no sense in them wasting B25 resources. They might as well be on B41 solely and possibly even let their device aggregate them with another B41 carrier. B41+B41 will always be better than B41+B25.

yep I know. vzw had to do that. atleast thin out 3G.

So are you saying band 25 would with CA if more useful when and, if sprint ever has a 4th LTE band in the future?

I understand. I think Sprint needs to do something about speeds for users who aren't close enough to receive B41 if Marcelo is serious about becoming the #1 or #2 network. Doesn't T-Mobile have CA on B12? Not sure.

Tmo may have the ability to run B12 CA through its network and devices, but it also actively shunts people on B12 over to B4 if they are in range of it.  They aren't going to let people who can use another band (that is much wider) waste resources on B12.  

 

You say that Sprint should do something about speeds for users who aren't close enough to receive B41.  The best thing they can do is kick people off B26 who could be using B25 or B41.  When B26 only has users on it that are only in overage of that band, B26 performs pretty darn well.  And if aggressively managed, it could run 10-30Mbps in most instances.

      T-Mobile interferes with NextWave's network, FCC finds https://www.lightreading.com/5g/t-mobile-interferes-with-nextwave-s-network-fcc-finds At this point, T-Mobile should just open up the checkbook and pay whatever it takes together rid of NextWave for good.

      Flashback (January 11, 2018): Sprint Says No to mmWave, Yes to Mobile 5G https://www.lightreading.com/5g/sprint-says-no-to-mmwave-yes-to-mobile-5g Sprint's CTO said Wednesday that he is not sure that using millimeter waves to deliver 5G services is a practical economic use of the high-band spectrum and that Sprint will be focusing on using its existing bandwidth to deploy 5G, at least initially. "What is the cost to deliver a bit over millimeter waves? Where is the business case on that?" John Saw asked at the Citi conference in Las Vegas. The logic here is that using sub-6GHz networks to deliver 5G -- Sprint Corp. (NYSE: S) is using 2.5GHz -- will allow operators to get better coverage than mmWave (typically 28GHz or 39GHz) and re-use its infrastructure.

      It looks like they have 700mhz of 24ghz n258 in those areas anyway. Seems like they've been trying to streamline mmw to just n258 anyway.

      New n261 license reduction for Brooklyn and Queens kinda gives insight into T-Mobile's mmWave plans going forward. While it sucks that they aren't going to widely deploy it in the outer boroughs, they chose great areas to retain the license. Downtown Flushing, Long Island City, Dumbo, Greenpoint, and Williamsburg all make the cut which is pretty obvious given their density.  I'm surprised to see Red Hook make it in and the entire waterfront along Sunset Park. Maybe they plan on some mmWave small cells along 1st Ave in Industry City. Also looks like they retained the license in the party section of Bushwick/East Williamsburg where Elsewhere, House of Yes, Brooklyn Mirage, etc. all are so that would be cool to see get covered in mmWave. In Queens they scooped up Citi Field, Billie Jean King National Tennis Center, and all of Flushing Meadows Park which should be helpful for all of the festivals that take place in that part of Queens. Also looks like they kept the license for LGA but not for JFK.
