How can I hide my Mac's Airport WiFi?

Hi! I have a new Mac Pro with Airport WiFi at my office. I want to be able to hide the WiFi broadcast if possible. I need it for a couple of things, but my boss has asked for me to not be the source of wireless connections in the office (iPads, smart phones and such). To hide it if possible). Is it possible? How would I set that up?

Thanks!
