A monitoring device (141) can include a transceiver (202) to receive a
radio signal, and a controller (203) communicatively coupled to the
transceiver to detect an infringement on the radio signal and report the
infringement to a database. One or more policies within the database can
be updated to mitigate the infringement. The monitoring device can also
detect whether a cognitive radio (111) is generating interference on a
primary spectrum used by an incumbent device (151). Other embodiments are
disclosed.
