Overview
1. Introduction
Overview
Thank you for purchasing the ASUS WLAN Card. The ASUS WLAN Card is
a PCI compliant “wireless” network interface card (NIC) for any computer
equipped with a PC Card slot (available mainly in Notebook PCs).
The ASUS WLAN Card is designed to be fully compliant with both the IEEE
802.11g and IEE802.11b wireless local area network (Wireless LAN) standards.
As a result of the completion of the standard, the interoperability of Wireless
LAN products among multiple manufacturers will be guaranteed. The ASUS
WLAN Card product provides high-speed, standards-based Wireless LAN
solutions.
The ASUS WLAN Card is designed to be fully compliant with IEEE 802.11g
wireless local area networks (WLAN). 802.11g is an extension to 802.11b,
used in majority of wireless LANs today. 802.11g will broaden 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.
The ASUS WLAN Card supports data rates up to 11 Mbps, with automatic
fallback to 5.5, 2, and 1 Mbps in 802.11b networks. It operates in the unlicensed
2.4 GHz frequencies called the Instrumentation, Science, and Medical (ISM)
band. Unlicensed means free of charge to users.
The ASUS WLAN Card configuration utility is a user-friendly application that
helps you quickly setup multiple roaming nodes using the ASUS WLAN Card.
You can even export the configuration settings to a file and import them to
other computers for fast multiple installations using ASUS Mobile Manager.
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 of
ASUS WLAN Access Points or ASUS WLAN Home Gateways. ASUS WLAN
Home Gateways 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.

Use the Channel field to select the radio channel for ASUS WLAN Card. In an
"infrastructure" network, your ASUS WLAN Card will automatically select
the correct frequency channel required to communicate with an Access Point,
this parameter will be fixed in "Auto" and cannot be changed. In an "Ad Hoc"
network, you can decide the channel number for the ASUS WLAN Card. Any
ASUS WLAN Card can communicate in the same network if they have the
same frequency channel setting.
The radio channels you may use depend on the regulations in your country. For
United States (FCC) and Canada (IC), channels 1 to 11 are supported.

Chapter 3
Windows Settings
Lets you configure the ASUS WLAN Card encryption settings. For data
confidentiality in a wireless environment, IEEE 802.11 specifies a Wired
Equivalent Privacy (WEP) algorithm to offer transmission privacy similar to
wired network. The WEP uses keys to encrypt transmit data packets and decrypt
received data packets. The encryption process can scramble frame bits to avoid
disclosure to others.
Pull Down Menus
Data encryption (WEP enabled)
This option allows you to enable or disable the Wired Equivalent Privacy (WEP)
function. If this check box is selected, a WEP Key is used to encrypt your data
before it is transmitted over the air.
If you enable WEP encryption, you will only be able to communicate with
wireless devices that have use the same WEP keys.
WEP Key
This option is enable only if you enable WEP Encryption. The WEP Key is a
64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypt
transmit data packets and decrypt received data packets.
Key Format
You can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or as
ASCII characters, based on the state of the Key Format.

Key Length
For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII
characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or
13 ASCII characters.
Two ways to assign WEP keys
Chapter 3
Windows Settings
1. Manual Assignment - When you click this button, the cursor appears
in the field for Key 1. For 64-bit encryption, you are required to enter
four WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and
A~F). For 128-bit encryption, you are required to enter four WEP Keys.
Each Key contains exactly 26 hex digits (0~9, a~f, and A~F).
2. Automatic Generation - Type a combination of up to 64 letters, numbers, or symbols in the Passphrase column, then the Wireless Settings
Utility uses an algorithm to generate four WEP Keys for encryption.
NOTE: This function ease users from having to remember their
passwords and is compatible to some existing WLAN utilities, but
it is not very secure. "Manual Assignment" is more secure.
Default Key
The Default Key field lets you specify which of the four encryption keys you
use to transmit data on your wireless LAN. You can change the default key by
clicking on the down arrow at the right of this field, selecting the number of the
key you want to use and then clicking the Apply button. As long as the Access
Point or station with which you are communicating has the same key in the
same position, you can use any of the keys as the default.
You then click the Apply button to create your encryption keys. After you click
the Apply button, the Wireless Settings Utility uses asterisks to mask your
keys.
NOTE: Click the Apply or OK button to save the encryption settings. The keys you entered will be masked by asterisks.

64/128bits versus 40/104bits
You may be confused about configuring WEP encryption, especially when
using multiple wireless LAN products from different vendors. There are
two levels of WEP Encryption: 64 bits and 128 bits.
First, 64 bit WEP and 40 bit WEP are the same encryption method and can
interoperate in the wireless network. This lower level of WEP encryption
uses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 64
bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and
others refer to this as 64 bits. ASUS WLAN products use the term 64 bits
when referring to this lower level of encryption.
Chapter 3
Windows Settings
Second, 104 bit WEP and 128 bit WEP are the same encryption method
and can interoperate in the wireless network. This higher level of WEP
encryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),
and a 24 bit “Initialization Vector” (not under user control). This together
makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104
bits and others refer to this as 128 bits. ASUS WLAN products use the
term 128 bits when referring to this higher level of encryption.

IEEE 802.11b (11Mbits/sec)
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted
the 802.11 standard for wireless devices operating in the 2.4 GHz frequency
band. This standard includes provisions for three radio technologies: direct
sequence spread spectrum, frequency hopping spread spectrum, and infrared.
Devices that comply with the 802.11 standard operate at a data rate of either 1
or 2 Mbps.
In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identical
to the 802.11 standard except 802.11b provides for data rates of up to 11 Mbps
for direct sequence spread spectrum devices. Under 802.11b, direct sequence
devices can operate at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This provides
interoperability with existing 802.11 direct sequence devices that operate only
at 2 Mbps.
Direct sequence spread spectrum devices spread a radio signal over a range of
frequencies. The IEEE 802.11b specification allocates the 2.4 GHz frequency
band into 14 overlapping operating Channels. Each Channel corresponds to a
different set of frequencies. See the Appendix to determine the center frequency
used by each Channel.
Chapter 5
Glossary
If operating multiple 802.11b Wireless ASUS WLAN Cards in the same vicinity,
the distance between the center frequencies must be at least 25 MHz to avoid
interference. In the United States, the 802.11b standard allocates 11 operating
Channels for direct sequence devices. Channels 1, 6, and 11 are standard allocates
11 operating Channels for direct sequence devices. Channels independent and
do not overlap with each other. To avoid interference between 802.11b
Wireless ASUS WLAN Cards, It is recommended that you configure the Wireless
ASUS WLAN Cards using only Channels 1, 6, and 11.
ASUS WLAN Card

Chapter 5 - Glossary
Direct-Sequence Spread Spectrum (for 802.11b)
Spread spectrum (broadband) uses a narrowband signal to spread the
transmission over a segment of the radio frequency band or spectrum. Directsequence is a spread spectrum technique where the transmitted signal is spread
over a particular frequency range. The Space Link Wireless ASUS WLAN
Card uses Direct-Sequence Spread Spectrum (DSSS) for radio communication.
Direct-sequence systems communicate by continuously transmitting a redundant
pattern of bits called a chipping sequence. Each bit of transmitted data is mapped
into chips by the Wireless ASUS WLAN Card and rearranged into a
pseudorandom spreading code to form the chipping sequence. The chipping
sequence is combined with a transmitted data stream to produce the Wireless
ASUS WLAN Card output signal.
Wireless mobile clients receiving a direct-sequence transmission use the
spreading code to map the chips within the chipping sequence back into bits to
recreate the original data transmitted by the Wireless ASUS WLAN Card.
Intercepting and decoding a direct-sequence transmission requires a predefined
algorithm to associate the spreading code used by the transmitting Wireless
ASUS WLAN Card to the receiving wireless mobile client.
Chapter 5
Glossary
This algorithm is established by IEEE 802.11b specifications. The bit
redundancy within the chipping sequence enables the receiving wireless mobile
client to recreate the original data pattern, even if bits in the chipping sequence
are corrupted by interference. The ratio of chips per bit is called the spreading
ratio. A high spreading ratio increases the resistance of the signal to interference.
A low spreading ratio increases the bandwidth available to the user. The Wireless
ASUS WLAN Card uses a constant chip rate of 11Mchips/s for all data rates,
but uses different modulation schemes to encode more bits per chip at the
higher data rates. The Wireless ASUS WLAN Card is capable of an 11 Mbps
data transmission rate, but the coverage area is less than a 1 or 2 Mbps Wireless
ASUS WLAN Card since coverage area decreases as bandwidth increases.

Chapter 5 - Glossary
IEEE 802.11a (54Mbits/sec)
The 802.11b standard was designed to operate in the 2.4-GHz ISM (Industrial,
Scientific and Medical) band using direct-sequence spread-spectrum technology.
The 802.11a standard, on the other hand, was designed to operate in the more
recently allocated 5-GHz UNII (Unlicensed National Information Infrastructure)
band. And unlike 802.11b, the 802.11a standard departs from the traditional
spread-spectrum technology, instead using a frequency division multiplexing
scheme that's intended to be friendlier to office environments.
The 802.11a standard, which supports data rates of up to 54 Mbps, is the Fast
Ethernet analog to 802.11b, which supports data rates of up to 11 Mbps. Like
Ethernet and Fast Ethernet, 802.11b and 802.11a use an identical MAC (Media
Access Control). However, while Fast Ethernet uses the same physical-layer
encoding scheme as Ethernet (only faster), 802.11a uses an entirely different
encoding scheme, called OFDM (orthogonal frequency division multiplexing).
The 802.11b spectrum is plagued by saturation from wireless phones, microwave
ovens and other emerging wireless technologies, such as Bluetooth. In contrast,
802.11a spectrum is relatively free of interference.
Chapter 5
Glossary
The 802.11a standard gains some of its performance from the higher frequencies
at which it operates. The laws of information theory tie frequency, radiated
power and distance together in an inverse relationship. Thus, moving up to the
5-GHz spectrum from 2.4 GHz will lead to shorter distances, given the same
radiated power and encoding scheme.
ASUS WLAN Card
67
Chapter 5 - Glossary
COFDM (for 802.11a/g)
Signal power alone is not enough to maintain 802.11b-like distances in an
802.11a/g environment. To compensate, a new physical-layer encoding
technology was designed that departs from the traditional direct-sequence
technology being deployed today. This technology is called COFDM (coded
OFDM). COFDM was developed specifically for indoor wireless use and offers
performance much superior to that of spread-spectrum solutions. COFDM
works by breaking one high-speed data carrier into several lower-speed
subcarriers, which are then transmitted in parallel. Each high-speed carrier is
20 MHz wide and is broken up into 52 subchannels, each approximately 300
KHz wide. COFDM uses 48 of these subchannels for data, while the remaining
four are used for error correction. COFDM delivers higher data rates and a
high degree of multipath reflection recovery, thanks to its encoding scheme
and error correction.
Each subchannel in the COFDM implementation is about 300 KHz wide. At
the low end of the speed gradient, BPSK (binary phase shift keying) is used to
encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps,
data rate. Using quadrature phase shift keying, you can double the amount of
data encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And by
using 16-level quadrature amplitude modulation encoding 4 bits per hertz, you
can achieve a data rate of 24 Mbps. The 802.11a/g standard specifies that all
802.11a/g-compliant products must support these basic data rates. The standard
also lets the vendor extend the modulation scheme beyond 24 Mbps. Remember,
the more bits per cycle (hertz) that are encoded, the more susceptible the signal
will be to interference and fading, and ultimately, the shorter the range, unless
power output is increased.
