[HELP a Network Noob] What does 20+20 mhz LTE mean?

[optimummind]

Hello~!

 

I read an article about T-Mobile rolling out 20x20 MHz (20+20 MHz) LTE to select cities and I realized I have no idea what 20+20 MHz LTE means.    I performed a Google search but I can't find any articles that explain the differences between 5x5, 10x10, 20x20, etc. 

 

Can someone explain what this terminology means or link me to an article that explains all this stuff?

 

Thanks.

20 MHz of download, 20 MHz of upload. 

 

The more, the better. Although for LTE I believe it maxes out at 20 MHz.
