A method for determining placement of radio frequency security devices (RFSDs) within a secured space to create a perimeter for primary devices of a wireless local area network (WLAN) within said secured space and to reduce detection of transmitted packets that go on an excursion from said WLAN to external networks, said method comprising:

  • determining a radio frequency map of a network environment;

    determining signal strength of an external network;

    determining signal strength of the WLAN;

    comparing the determined signal strengths;

    determining radiation patterns; and

    based on said compared signal strengths and said determined radiation patterns, adjusting antenna systems of each RFSD to cloak or sanitize an affected packet in response to one of a packet emitted from said WLAN or a packet emitted from said external network, which approaches and traverses said perimeter.
