.SH DESCRIPTION
.B Iwspy
-is used to set a list of addresses in a wireless network interface and
-to read back quality of link information for each of those. This
-information is the same as the one available in
+is used to set a list of addresses to monitor in a wireless network
+interface and to read back quality of link information for each of
+those. This information is the same as the one available in
.I /proc/net/wireless
: quality of the link, signal strength and noise level.
.PP
This information is updated each time a new packet is received, so
-each address of the list add some overhead in the driver.
+each address of the list adds some overhead in the driver.
.PP
-Note the this functionality work only for node part of the current
-wireless cells.
+Note that this functionality works only for nodes part of the current
+wireless cell, you can not monitor Access Points you are not
+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.

-Every time the signal strengh for any of the address monitored
+Every time the signal strength for any of the address monitored
with iwspy goes lower than the low threshold or goes higher than the
high threshold, a Wireless Event will be generated.
