Overview
Thankyoufor purchasingtheASUS 802.11g WLANAP.TheASUS 802.11g
APis anAccess Point designed to be fully compliant with IEEE pre 802.11g
and 802.11b standards. 802.11g is a proposed (to be finalized) new extension
to 802.11b (used in majority of wireless LANs today) that broadens
802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM
(orthogonal frequency division multiplexing) technology. 802.11g allows
backward compatibility with 802.11b devices but only at 11 Mbps or lower,
depending on the range and presence of obstructions.
Wireless LANs are complementary extensions to existing wired LANs,
offering complete mobility while maintaining continuous network
connectivity to both corporate and home Intranets.They add a new level of
convenience for LAN users. PC users stay connected to the network
anywhere throughout a building without being bound by a LAN wires.
This is accomplished through the use ofASUSAccess Points.ASUSAccess
Points with built-in Internet gateway capability, allows your family to share
a broadband Modem and one ISP account simultaneously from different
rooms without wires! ASUS WLAN products can keep you connected
anywhere, any time.

Chapter 1 - Introduction
Wireless Performance
This section provides the user with ideas for how to improve the performance
of aASUS 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,andotherindustrial equipment.Signallosscanoccur when
metal, concrete, walls or floors block transmission. Locate the ASUS AP s in
open areas or add theASUS 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 theASUS 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
withouttesting.However,has developedsome guidelinesto estimatethe 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 theASUSAP 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 theASUS AP will use. If you limit the range of data rates available to the
ASUSAP,you mayreducetheeffectivewirelessrangeoftheWLANcoverage.
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.

1. Introduction
Chapter 1 - Introduction
12 ASUS 802.11g Access Point
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.
Each ASUS AP creates 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
mayswitch from oneASUSAPto another as it travels throughout the facility.
During the hand-off from one ASUS AP to another, the wireless mobile
client maintains an uninterrupted connection to the network. This is known
as “roaming.”
Multiple ASUS APs 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.
• All computers with ASUS WLAN Cards must have the same SSID as
the Access Points that they will roam between.
• If WEP encryption is enabled, then all ASUS APs and client adapters
must use the same encryption level and WEP Key(s) to communicate.
• The 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.
• ASUS APs 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 facility.
