How To Survey for the WIPT
Figure4-6 AirMagnet Survey Active Mode
To survey a group of access points using the Active Mode tool, configure the tool with an SSID that is
configured on the access points.
To begin the data collection in active mode, select a starting position near the perimeter of the area to be
covered. Click this location on the floor map to indicate the starting point. A small stick figure appears
on that spot. Begin the walkabout by moving at a smooth rate to the next vertex in the path; stop briefly
to click this spot, and continue.
The survey tool control area displays various real-time data as you conduct the survey. Use the data to
monitor the state of the link. The signal strength, noise level, link speed, and packet loss statistics are
all displayed.
Figure 4-7 shows the complete walkabout path taken for an example coverage area. Note that the path
includes a section outside the perimeter walls of the building. Continuing the walkabout outdoors
measures possible propagation outside of the building, where the signal level should be as low as
possible without compromising connectivity to the interior areas , which helps prevent unauthorized
connections to the WLAN.
