# This example prints out all the AP BSSIDs that all Wi-Fi devices on the
# machine can see.  Useful for location-based services like Skyhook that
# can geolocate you based on the APs you can see.
#
# Note that with NetworkManager clients are required to request scanning.
# If you don't do that, the scan list may be outdated. That means, you would
# check the LastScan property, and if necessary call RequestScan() first.
# After RequestScan(), you wait until the LastScan property gets bumped again.
