Hi all,
I am architecting a project in which it will be helpful to control the radio power of the WiFi on the Pi 3. Can this be done?

In general the answer is yes, but it depends on the Linux you have installed and chip driver capabilities.. See https://wireless.wiki.kernel.org/en/developers/documentation/ieee80211/power-savings for a discussion.

Thanks for jumping in, Clem. I genuinely appreciate.
And forgive me but I'm not sure I was entirely clear. I am not concerned with saving power but with actually reducing the broadcast power of the WiFi radio. The application I'm architecting operates in a very small area, and the design of the associated hardware elements may be simplified if I can actually reduce the broadcast power of the WiFi radio on the Pi 3 board.
Of course if I simply missed that in the pointer you sent me, please point out what a dolt I am. I never mind being corrected.
And thanks again for your help.

Here is the details of the Broadcom wireless chip in Raspberry Pi 3 in http://www.cypress.com/file/298076/download . There are a few sections mentioning the power management feature. Beware that although the chip may do these things, the driver code in the OS may or may not support such features like I stated above. Especially since this is new chip. I would consider maybe using your own wireless solution if this proves to be not supported at this time. Sorry for long winded answer.

Thank you again, Clem, for this pointer. I'm going through the specs now, and if between the Cypress/Broadcomm chip and the OS broadcast power is not manageable, I'll certainly be following your suggestion and using my own wireless solution.
