B3 + B38/41 aggregation on a quiet tower and Rain told me that 4x4 mimo although it theoretically trumps B3+B38/41 aggregation on max atainable download speed aggregation works best speed wise.

Couple of LTE technologies that are available to speed things up for the end users.

4x4 mimo
carrier aggregation

are the 2 that are the most popular as far as I can tell.

4x4 mimo is like a download manager if I can put it in simple terms. On a 4x4 mimo router/phone it has 4 send and receive radios. It basically connects 4 individual streams to the same tower increasing download speed.

Carrier aggregation is when the phone combines spectrum that are scattered over different radio frequency. FOr Rain it's 10MHz in 1800MHz band aka Band 3 and 20MHz in 2600MHz band aka Band 38 which is a family band from band 41.

When carrier aggregation happen then obviously it does not use 4x4 mimo because the radios are used for connecting to the other band. When 4x4 mimo is active it won't aggregate because the 4 radios are used for mimo.
