    Conducting a Site Survey for Detecting Access Points

    When setting up the NetScreen-5GT Wireless (ADSL) device as a wireless access point (WAP), you can scan the broadcast vicinity to see if there are any other WAPs broadcasting nearby. A site survey detects any WAPs emitting a beacon in its area and records the following details about each detected WAP:

    • Service set identifier (SSID)
    • MAC address
    • Received signal strength indicator (RSSI) The RSSI numbers are in decibels (dBs) that indicate the signal-to-noise ratio (SNR). The SNR is the signal level divided by the noise level, which results in a value representing signal strength.
    • Broadcast channel

    In addition to performing an initial site survey, you might want to perform occasional surveys to ensure that no rogue WAPs are operating in the area.

    A site survey takes about 5-10 seconds to complete.
