set to the operational values. You should also try to perform
the survey during the time the RF link will generally be func-
tioning with all other systems and noise sources opera-
tional. For efficiency, you should execute the site survey
application entirely from the mobile station.
The link test tool helps determine the RF network coverage.
The results of the link test will help eliminate low RF signal
level areas that can result in loss of connection between the
PC Card and the Aironet Access Point.
It is important to remember the information being displayed
is from the Aironet Access Point's viewpoint. Therefore,
packets sent are from the Aironet Access Point to the PC
Card client. Packets received are from the PC Card to the
Aironet Access Point. Signal quality is an estimate of the
signal strength recorded at the time of packet reception by
the radio.
Note: If your Wireless LAN Adapter contains new firmware,
you can use WinDGS's Active Mode Survey. See "Using the
Site Survey Active Mode Feature" on page 3-57 for details.
The Overall Link Quality rating on the Site Survey window
indicates the ability of the Aironet Wireless LAN Adapter to
successfully communicate with an Access Point. Ratings
are Excellent, Good, Fair, and Poor. The rating is derived
from the Current Signal Strength (PC4500/PC4800) and
Current Signal Quality.
• Excellent: Both values are greater than 75%
• Good: Both values are greater than 40%, but one or
both are less than 75%
• Fair: Both values are greater than 20% but one or both
are less than 40%
• Poor: One or both values are less than 20%
