Default An explanation regarding picking 2G/3G/LTE needed.

I'm trying to setup Tasker to activate 2G when I'm at home and to activate LTE when leaving home but I can't. I am lacking something that appears to be implemented in the CM kernel.

What is it and is it possible to sort out with a mod for stock roms?
I''ll add a few pictures for a more thorough look at it.
