+# bgscan: Background scanning
+# wpa_supplicant behavior for background scanning can be specified by
+# configuring a bgscan module. These modules are responsible for requesting
+# background scans for the purpose of roaming within an ESS (i.e., within a
+# single network block with all the APs using the same SSID). The bgscan
+# parameter uses following format: "<bgscan module name>:<module parameters>"
+# Following bgscan modules are available:
+# simple - Periodic background scans based on signal strength
+# bgscan="simple:<short bgscan interval in seconds>:<signal strength threshold>:
+# <long interval>"
+# bgscan="simple:30:-45:300"
+# learn - Learn channels used by the network and try to avoid bgscans on other
+# channels (experimental)
+# bgscan="learn:<short bgscan interval in seconds>:<signal strength threshold>:
+# <long interval>[:<database file name>]"
+# bgscan="learn:30:-45:300:/etc/wpa_supplicant/network1.bgscan"
