Chapter 1 - Introduction  
Wireless Performance  
This section provides a few ideas to help you improve the performance of  
your WLAN.  
Site Topography  
For optimal performance, locate wireless mobile clients and the ASUS  
Wireless "WL-HDD" away from transformers, heavy-duty motors,  
fluorescent lights, microwave ovens, refrigerators, and other industrial  
equipment. Signal loss can occur when metal or concrete walls or floors  
block transmission. Locate the ASUS Wireless "WL-HDD" in open areas  
or add more devices (APs) as needed to improve coverage.  
Microwave ovens operate in the same frequency band as theASUS Wireless  
"WL-HDD". Therefore, if you use a microwave oven within range of your  
device, you may notice network performance degradation. However, your  
microwave oven and ASUS Wireless "WL-HDD" will continue to function.  
Range  
Every environment is unique with different obstacles, barriers, materials,  
and so on. Therefore, it is difficult to determine the exact range of your  
WLAN without testing in the specific environment. However, you can  
follow some of the guidelines described in this section to estimate the range  
of your network.  
Radio signals may be reflected by some obstacles or absorbed by others  
depending on their construction. For example, with two 802.11b radios,  
you may achieve clear reception over a distance of up to 1000 feet in open  
spaces, with the two devices being in line of sight (meaning they have no  
obstacles in a straight line between them). However, the same two units  
may only achieve up to 300 feet of range when used indoors.  
By default, the ASUS Wireless "WL-HDD" automatically adjusts the data  
rate to maintain a usable signal connection. Therefore, a client that is close  
to the ASUS Wireless "WL-HDD" may operate at higher speeds while a  
client that is on the fringe of coverage may operate at lower speeds. You  
can configure the data rates used by the ASUS Wireless "WL-HDD" to  
improve the performance. However, if you limit the range of data rates  
available to the ASUS Wireless "WL-HDD", you may reduce the effective  
wireless range of the WLAN coverage.

Chapter 1 - Introduction  
Site Surveys  
A site survey analyzes the installation environment and provides users with  
recommendations for equipment and its placement. The optimum placement  
differs depending on the ASUS AP design and specifications.  
Roaming Between ASUS APs  
If there are multiple ASUS APs on the network, then a wireless mobile client  
may seamlessly roam from one ASUS AP to another.  
EachASUSAPcreates its own wireless cell or coverage area. This is also known  
as a Basic Service Set (BSS). Any wireless mobile client can communicate with  
a particular ASUS AP if it is within the ASUS AP’s coverage area.  
If the cells of multiple ASUS APs overlap, then the wireless mobile client may  
switch from oneASUSAPto another as it travels throughout the building. During  
the hand-off from oneASUSAP to another, the wireless mobile client maintains  
an uninterrupted connection to the network. This is known as “roaming.”  
MultipleASUSAPs connected to a common Ethernet network form an Extended  
Service Set (ESS). All members of an Extended Service Set are configured with  
an ID, known as the SSID or ESSID. Wireless mobile clients must be configured  
with the same SSID as the ASUS APs on the network; a client can only roam  
between ASUS APs that share the same SSID.  
Roaming Guidelines  
• An ASUS WLAN card can only roam between APs of the same type.  
• All ASUS APs must have the same SSID.  
• AllASUS WLAN cards must have the same SSID as theAPs that they will  
roam between.  
• If WEP encryption is enabled, then all ASUSAPs and client adapters must  
use the same encryption level and WEP Key(s) to communicate.  
• ASUS APscells must overlap to ensure that there are no gaps in coverage  
and to ensure that the roaming client will always have a connection available.  
• ASUSAPs that use the same Channel should be installed as far away from  
each other as possible to reduce potential interference.  
• It is strongly recommended that you perform a site survey using the utility  
provided with the ASUS WLAN card to determine the best location for  
each ASUS AP in the building.

Chapter 2 - Getting Started  
2. Getting Started  
Location Tips  
• Determine the best location for the device while keeping in mind the  
following considerations:  
• The length of the Ethernet cable that connects the device to the network  
must not exceed 100 meters.  
• For standard placement, try to place the device on a flat, sturdy surface as  
far from the ground as possible, such as on top of a desk or bookcase,  
keeping clear of metal obstructions and away from direct sunlight.  
• For external antenna mounting, install the external antennas so that they  
are clear of obstructions; refer to the documentation that came with the  
antennas for mounting and installation instructions.  
• Try to centrally locate the device and its antenna so that it will provide  
coverage and access to its hard disk drive to all of the wireless mobile  
devices in the area.  
• Use only the power supply that came with this unit. Other power supplies  
may fit but the voltage and power may not be compatible.  
Note: It is the responsibility of the installer and users of the ASUS  
Wireless "WL-HDD" to guarantee that the antenna is operated at  
least 20 centimeters from any person. This is necessary to ensure  
that the product is operated in accordance with the RF Guidelines  
for Human Exposure which have been adopted by the Federal Com-  
munications Commission.  
Making Connections  
You can use your ASUS Wireless "WL-HDD" as an Access Point or as a  
wireless network storage device in an existing WLAN. When the ASUS  
Wireless "WL-HDD" is turned on, it searches for other existing Access  
Points in its vicinity. If no other AP is found, it acts as an AP, while at the  
same time allowing access to its hard disk drive. If an existing WLAN and  
AP is found in the vicinity, it acts as a wireless shared hard disk that can be  
accessed by other wireless clients in the WLAN.
