Before Using the Wireless LAN

This manual describes the procedures required to prop-
erly setup and configure the optional integrated Wireless
LAN Mini-PCI device (referred to as "WLAN device" in
the rest of the manual). Before using the WLAN device,
read this manual carefully to ensure it's correct opera-
tion. Keep this manual in a safe place for future refer-
ence.

Wireless LAN Devices Covered by this Document

This document is applicable to systems containing one
of the following two devices. Most of the procedures are
identical. Sections that differ between the two devices
have been noted in the text:

■

Intel® PRO/Wireless 3945ABG (WM3945ABG)
Network Connection (802.11a+b/g)

■

Atheros® AR5006EXS (AR5BXB6) Mini-Card
Wireless network card (802.11a+b/g)

Characteristics of the WLAN Device

■

The WLAN device is a Mini-PCI card attached to the
main board of the mobile computer.

■

It operates in two license-free RF bands, therefore
eliminating the need to procure an FCC license to
operate. It operates in the 2.4GHz Industrial, Scien-
tific, and Medical (ISM) RF band and in the lower and
middle bands of the 5GHz Unlicensed National Infor-
mation Infrastructure (UNII) bands.

■

The WLANs are capable of three operating modes,
IEEE802.11a, IEEE802.11b and IEEE802.11g, wireless
LAN standards governed by the IEEE (Institute of
Electronics and Electrical Engineers).

■

Encoding of data is modulated using Direct Sequence
Spread Spectrum (DSSS) and Complementary Code

Keying (CCK) when the WLAN device is operating in
IEEE 802.11b mode and Orthogonal Frequency Divi-
sion Multiplexing (OFDM) when operating in
IEEE802.11a or IEEE802.11g mode.

■

The WLAN device is Wi-Fi certified and operates at
the maximum data transfer rate of 54 Mbps in
IEEE802.11a or IEEE802.11g mode and 11 Mbps in
IEEE802.11b mode.

■

The WLAN device supports the following encryption
methods - WEP, TKIP, and AES encryption.

Wireless LAN Modes Using this Wireless Module

Ad Hoc Mode

(See Figure A-1)

“Ad Hoc Mode” refers to a type of wireless network that
involves connecting multiple computers without the use
of an Access Point. Network connectivity between
computers can be established using only wireless LAN
cards in a peer-to-peer fashion.

Ad Hoc networks are an easy and inexpensive method
for establishing network connectivity between multiple
computers.

In Ad Hoc mode, you can use Microsoft Network func-
tions, such as File and Print Sharing to share folders,
printers, or other peripheral devices, and exchange files
with other computers.

To use Ad Hoc Mode, you must set the same SSID and
the same encryption key for all the computers that are
connected. Communication between computers in an
Ad Hoc network will occur provided they are within
each other’s RF coverage area.
