Question about Carrier aggregation

[Kearney]

Ok. I have a note 5 that i can set in a window and get great speeds. Its on band 41 and has 2 matching cell id's and 2 download channels. Everything works perfect. Now i have a ZTE pocket wifi also sprint lte plus. I set it in the same window but can only get one cell and no conection. Its like it wont grab the secondary cell.

 

Here is whats weird. My phone while driving around always has matching primary and secondary cell id's with 2 downloading channels. My ZTE pocket wifi will only get carrier aggregation when the 2 cell id's are different. And its never as fast as my phone.

 

I dont get it. I set up a mimo antenna to the ZTE pocket wifi and aimed at the tower my phone gets band 41 w/CA and still even with better rsrp it only connects to one cell and has no conection. I aim the mimo to another tower further away and get 2 seperate cell id's on band 41 with terrible rsrp and get decent speeds but it wants to jump back to bands 25 and 26 after a while.

 

Does the ZTE pocket wifi not have true carrier aggregation?

Are you on the most current software version? I have a ZTE Pocket WiFi at work and see CA consistently whenever there is an active data connection. It is important to remember that devices will idle on either carrier, but not stay attached to both unless there is an active data connection.

The only difference i see is my note 5 does have an ipv6 adress and the ZTE pocket wifi does not. Its turned off. I turned it on but it goes back off.

 

Im on the most current software. I have to put it in lte only mode to even get it to try to connect to the same tower as my note 5. The note 5 will grab 2 download channels and work perfect. The ZTE will only grab one, say conected but have no internet at all. If i aim my external mimo at a further away tower the ZTE will grab 2 seperate cell id's and then grab 2 seperate download channels and work. But its a terrible signal and it wants to drop to band 25 or 26.

 

Does same cell id carrier aggregation only work with an ipv6? Thats the only thing i can think of.

Does the apn settings change anything? R.ispn between n.ispn? Thats another difference

Hmmm, I don't think it's ipv6 limited though. 

 

Definitely a head scratcher man.
