ABSTRACT:
Apparatus for eavesdropping within an area layer adjacent to and surrounding a LAN area periphery for potential wireless transmissions of an intruder having a lower frequency within a level below the LAN frequency; and an implementation responsive to said eavesdropping apparatus for changing the encryption code of said encrypted wireless transmission upon the eavesdropping detection of a wireless transmission of said lower frequency addressed to a network location of one of the terminals in said LAN.
