+Note that this functionality works only for nodes part of the current

+associated with (you can use Scanning for that) and nodes in other
+cells. In Managed mode, in most case packets are relayed by the Access
+Point, in this case you will get the signal strength of the Access
+Point. For those reasons this functionality is mostly useful in Ad-Hoc
+and Master mode.
