Editing Over-the-air update (section)

=== Internet routers ===
OTA is similar to firmware distribution methods used by other mass-produced [[consumer electronics]], such as [[cable modem]]s, which use [[TFTP]] as a way to remotely receive new programming, thus reducing the amount of time spent by both the owner and the user of the device on maintenance.

Over-the-air provisioning (OTAP) is also available in wireless environments (though it is disabled by default for security reasons).  It allows an access point (AP) to discover the [[IP address]] of its controller.  When enabled, the controller tells the other APs to include additional information in the Radio Resource Management Packets (RRM) that would assist a new access point in learning of the controller.  It is sent in plain text however, which would make it vulnerable to sniffing.  That is why it is disabled by default.
