Closed Verses Open RF Wireless

I have only come across this terminology in wireless networking for computers (PCs). In an open system the wireless network indicates that it exists and will respond with the value of its SSID to other wireless devices when they send out a RF beacon with an empty set SSID. On the otherhand in a closed system, the wireless adapter will not respond to empty set SSID beacons and will appear invisible to programs which rely on the open system technique to discover wireless networks.

There are possibly other interpretations of open and closed RF wireless systems, though this is the one I am aware of.
