3Com Corporation WL306 Manuel D’Utilisation

Setting up a basic wireless LAN can be as simple as placing a 3Com 11 Mbps 
Wireless LAN access point in a central area, plugging it in, and setting up one or 
more clients. However, you can be certain that you have selected the best location 
if you conduct a site survey before installing an access point permanently. The 
3Com Site Survey utility performs a set of tests that help you evaluate locations for 
3Com access point units.

You need the following items to conduct a site survey:

■

3Com 11 Mbps Wireless LAN access point, power adapter, and 
mounting hardware.

■

Wireless client laptop computer with a wireless PC card and the 3Com Site 
Survey tool installed. Alternatively, you can run the tests from client desktop 
computers with wireless PCI cards and the 3Com Site Survey tool installed. 

■

The IP address of the access point being surveyed. You can use the device 
manager tool that came with your 3Com access point or another network 
management tool to find the IP address.

To set up the tests, you install the access point temporarily in several trial locations. 

Look at your site floor plan and make a list of work areas where clients are likely to 
be positioned. For example, list the office cubicles where users will be logging on 
to the 3Com Wireless LAN. Then select several trial locations for the access point 
and make a list of these locations. For example, you may wish to test the access 
point mounted on the ceiling, on a desk, and on a wall. 

Look for locations in the center of the room and away from potential transmission 
barriers. Consider the following environmental and electrical factors when you 
choose locations.

Look for installation locations away from transformers, heavy-duty motors, 
fluorescent lights, microwave ovens, refrigerators, and other industrial equipment. 
Avoid areas with excessive moisture, heat, and dust. Signal loss can occur when 
metal, concrete, Interfering metal fire breaks, walls, or floors block transmission. 
Doorways and passages can also affect the radio signal.
