1. Introduction
Chapter 1 - Introduction
Overview
Thank you for purchasing the ASUS WLAN Card. The ASUS WLAN Card is
a PCMCIA 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 IEE802.1 1b 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 . 802.1 1g will broaden 802.1 1b'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.
Overview
Chapter 1
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, of fering
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 dif ferent
rooms without wires! ASUS WLAN products can keep you connected
anywhere, any time.

Config - Encryption Tab
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 W ired 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

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.

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.
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.

Bad link quality or bad signal strength
There are two possible reasons. First is radio interference, keep the environment
around the ASUS WLAN Card away from microwave ovens and large metal
objects. Then try to reorient the ASUS WLAN Card antenna. Second is the
distance, decrease the distance between your ASUS WLAN Card and the Access
Point or station (or another ASUS WLAN Card).
The TCP/IP protocol did not bind to the ASUS WLAN PC Card.
This will occur when the computer already has six TCP/IP bindings in Windows
98 or ten bindings in W indows Me. These limits are imposed by the Microsoft
operating system.
Solution: If your computer already has the maximum number of TCP/IP
bindings, remove one of the network adapters from the Network configuration
before installing the ASUS WLAN Card driver.

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. 802.1 1b is essentially identical
to the 802.11 standard except 802.1 1b provides for data rates of up to 1 1 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 802.1 1b 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.
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. Note that the Channels available to an 802.11b Wireless ASUS
WLAN Card will vary from country to country . In the United States, the 802.11b
standard allocates 11 operating Channels for direct sequence devices. Channels
1, 6, and 11 are 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 W ireless ASUS WLAN Cards using only Channels 1, 6,
and 11.

Chapter 5 - Glossary
Direct-Sequence Spread Spectrum (for 802.1 1b)
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 1 1Mchips/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 W ireless
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 802.1 1a 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.
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.

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.
Chapter 5
Glossary
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.
Note: This ASUS WLAN device only supports 802.11g and 802.11b.
802.11a is supported in other ASUS WLAN products.
