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 APs’cells 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.

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.
