Padavan greenAP feature

[fsatsil]

I just installed the latest Padavan firmware on my RT-N56U and it has a GreenAp feature. My question is, does this only work for non N cleints or will it also work for single stream N cleints? For example all my wireless connected devices are single stream N(iPhone, iPad..etc), if I turn on GreenAP will the router sense this and revert down to the power saving single stream mode? If not should I just manually set the router to 1T1R mode? Is there any benefit to turning on 2T2R and 2T3R if the cleints are only single stream?
thanks

if u r using a single stream devices, then there are no benefits having 2t2r or 2t3r.

Thats what I figured but I just wanted to make sure. Does anyone know about the GreenAp feature? Is it only for non N cleints?
