Section 2: Using the WinDGS Utilities

Site Survey

To perform a meaningful site survey, you need to conduct a

test that will accurately model the intended use of the sys-

tem. It is important to perform a site survey using equipment

which is similar to the equipment that will be implemented.

Common survey items include:

• Transmit power

• Antenna type(s)

• Antenna location(s)

• Packet (fragment) size

• Interference

You should always conduct a site survey with all variables

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

PCI/ISA 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 PCI/

ISA Card client. Packets received are from the PCI/ISA

Card to the Aironet Access Point. Signal quality is an esti-

mate 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 page34 for details.
