    The site I seen this on was a 8t8r sprint site. As a band 41 non ca site it was fast with peak speeds of over 60 and 70 during 2 or 3 am. It actually got slower with CA with peak speeds even that early only capping out at 30 mbps.

    Thats odd. How can i tell if this is a clear site?

    Think of it like this:

     

    There could be up to six 82mbps pipes. But phones can only use three of them at a time.

     

    The advantage of this over just three 82mbps pipes is you can have one user on three pipes and another user on the other three pipes and their data use wouldn't impact each other.

    GOT IT!! THANKS !! Now we just need band 26 and Phoenix might be set !

    Theoretical max for a single 10x10 is roughly 75 IIRC. So three of those would be about 225. Which is close to but slightly below the theoretical max of 247 for Sprint's 3xCA. But those are theoretical maximums and you are unlikely to see numbers that high during a normal day.

     

    But it is worth noting that in some cities Sprint will have 2 3xCA chains running long-term, so even though the theoretical max of 247 stays the same you would be more likely to hit it with Sprint than AT&T because the users-per-chain would be half of AT&T's (all other factors aside).

     

    But that's an oversimplification since Sprint and AT&T have different amounts of customers from city-to-city.

     

    Edit: forgot to mention Sprint might change the TDD ratios at some point which could put the theoretical max for 3xCA higher or lower than it is now. IIRC the commonly cited "capacity" configuration raises the theoretical max from 82 to about 110. AT&T does not have that option.

    Wow great info !!! I thought I read they would do 6xCA at some point .. I'm a guess that 2 carriers of 3xCA

    You don't need to add more equipment to add more capacity. All software and spectrum holdings.

     

    Basically once the 800+1.9 & 2.5 Equipment are installed. They're done unless they want to optionally add more physical sectors or upgrade another antenna radio set for 4x MIMO on lte like what's happening right now.

    Thanks for taking the time and answering all these questions I'm learning a lot at the time of help what type of speed you expect to see with 3x ca

    3xCA max. Then split the from 8t8r into two 4t4r and run a different 2x / 3xCA on the second sector using different frequencies.

     

    Future phones are capable of like up to 5xCA but the eNB have hardware limits on how much spectrum each port supports.

    So will that give sprint a future advantage over other carriers like say AT&T

    The Sprint-AT&T spectrum transaction seems directed mostly at problem markets, those with band 25 and/or band 41 limitations.

     

    Phoenix does not have a band 25 PCS problem. It has a band 26 SMR problem. Thanks, Joe Arpaio!

     

    Phoenix already has a band 25 second carrier at 5 MHz FDD. In the relatively near future, that will expand to 10 MHz FDD. So, Phoenix will have the band 25 first carrier at 5 MHz FDD, the band 25 second carrier at 10 MHz FDD, the band 26 carrier at 5 MHz FDD, and at least two band 41 carriers at 20 MHz TDD. Phoenix will be fine.

    Will 3xCA be something we get as well ?

    Phoenix is in a decent PCS spectrum situation right now with the full B block. With CDMA trimming, that should be enough for at least a 10x10 carrier eventually. I believe AT&T and T-Mobile both own parts of the C block in Phoenix area, so a spectrum swap may be a bit more difficult to work out. AJ or Tim may have a better idea of what could happen there.

    Thanks for the heads up
