Wireless Performance

This section provides the user with ideas for how to improve the performance

of a ASUS WLAN network.

Site Topography

For optimal performance, locate wireless mobile clients and the ASUS AP s

away from transformers, heavy-duty motors, fluorescent lights, microwave

ovens, refrigerators, and other industrial equipment. Signal loss can occur when

metal, concrete, walls or floors block transmission. Locate the ASUS AP s in

open areas or add the ASUS AP s as needed to improve coverage.

Microwave ovens operate in the same frequency band as the ASUS AP .

Therefore, if you use a microwave within range of the ASUS AP you may

notice network performance degradation. However, both your microwave and

your the ASUS AP will continue to function.

Range

Every environment is unique with different obstacles, barriers, materials, etc.

and, therefore, it is difficult to determine the exact range that will be achieved

without testing. However, has developed some guidelines to estimate the range

that users will see when the product is installed in their facility, but there are no

hard and fast specifications.

Radio signals may reflect off of some obstacles or be absorbed by others

depending on their construction. For example, with two 802.11b radios, you

may achieve up to 1000' in open space outdoors where two devices have a line

of sight, meaning they see each other with no obstacles. However, the same

two units may only achieve up to 300' of range when used indoors.

By default, the ASUS AP will automatically adjust the data rate to maintain a

usable radio connection. Therefore, a client that is close to the ASUS AP may

operate at higher speeds while a client that is on the fringe of coverage may

operate at lower speeds. As mentioned earlier, you can configure the data rates

that the ASUS AP will use. If you limit the range of data rates available to the

ASUS AP, you may reduce the effective wireless range of the WLAN coverage.

Site Surveys

A site survey (utility provided with the ASUS WLAN Cards) analyzes the

installation environment and provides users with recommendations for

equipment and its placement. The optimum placement differ depending on the

ASUS AP design and specifications.
