Patent Images
1. In a wireless local area network (LAN) comprising a plurality of computer controlled terminals within a defined area, a system for the secure wireless transmission of data to and from computer terminals in the LAN comprising:
- means for wireless transmission of data to and from computer terminals in the LAN at a selected LAN frequency level;
means for encrypting said wireless transmissions within said LAN;
means for eavesdropping within an area layer adjacent to and surrounding the LAN area periphery for wireless transmissions having a lower frequency within a level below the LAN frequency, whereby said lower frequency transmission would be directed to a remote location outside of said LAN area; and
means responsive to said eavesdropping means 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.

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.

7. A method for the secure wireless transmission of data to and from computer terminals in a wireless local area network (LAN) including a plurality of computer controlled terminals within a defined area comprising:
-
wirelessly transmitting data to and from computer terminals in the LAN at a selected LAN frequency level; encrypting said wireless transmissions within said LAN; eavesdropping within an area layer adjacent to and surrounding the LAN area periphery for wireless transmissions having a lower frequency within a level below the LAN frequency, whereby said lower frequency transmission would be directed to a remote location outside of said LAN area; and 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. - View Dependent Claims (8, 9, 10, 11, 12)
