 For precise signal strength values in dBm, use NETCONF or RESTCONF to access
 the `signal-strength` leaf in the operational datastore.
 
+When connected, `bssid` shows the MAC address of the access point the
+station is associated to.  It appears only while connected.  When several
+access points share one SSID (a roaming network), the `bssid` is what
+tells them apart, and it changes as the station roams between them.
