Follow these steps to plan your
sensor placement:
-
Obtain Maps/Layouts of the
facility and determine the traversal plan.
-
Start AirDefense Mobile.
-
Turn on the target device (
could be a laptop/PDA with wireless client card). AirDefense Mobile should detect
the target device.
-
Identify the target device in
the AirDefense Mobile device tree.and use your mouse to right-click on it to
display a list of options.
-
Use AirDefense Mobile Options to
Lock On the channel on which the target device is discovered.
-
Right-click select the device in
the Dashboard tree; select LiveView.
-
Focus on Signal Strength in the
Decode tab in LiveView. Verify that the target device is being tracked by
AirDefense Mobile.
-
When a wireless client (station)
card is being used as a target, significant peaks and valleys are observable in
signal strength as the card rotates through channels probing for any intrusion. The peaks
are indicative of the effective signal strength relative to AirDefense
Mobile.
-
Move the target device to the
anticipated fringe where a neighboring sensor would become primary.
-
At the fringe of coverage,
signal strength should be no less than -70 dBm to assure termination
ability.
-
Move AirDefense Mobile to the
anticipated location of the next sensor and use the same procedure to ensure
that its anticipated coverage area is valid.
If the above sensor placement proves adequate from a coverage and cost of
placement perspective, factors observed during this analysis may be
extrapolated to other locations of similar construction.
