RCM5600W sleep mode

I’m looking for information about a “sleep mode” for the RCM5600W. There’s no information about this in the RCM5600W UM pdf.

I would like to be able to turn off or suppress the wifi transmission when it is not in use, however I need to be able to turn the transmission back on wirelessly. Is this possible? My application for this RCM module is wireless only and the user will have no access to the hardware.

Any information would be great!

thx
