Hi Hao,

Could please elaborate on what 'wifi radio' means in your description. 
It makes me think about RFKILL, but that may not be the thing you are 
looking for. With it you can disable/enable the radio within the 
wireless chipset. The terms sleep and wakeup feel a little odd when 
talking about radios.
