Before Using the Wireless LAN
This manual describes the procedures required to properly setup and configure the optional integrated
Wireless LAN Mini Card 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 operation.
Wireless LAN Devices Covered by this Document
This document is applicable to systems containing the following WLAN device
• Atheros SuperAG Wireless LAN (802.11a+b/g)
Characteristics of the WLAN Device
• The WLAN device is a Mini Card attached to the mainboard of the mobile computer.
• It is a dual-band radio that 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, Scientific, and Medical (ISM) RF band.
Additionally, the Atheros device operates in the lower, middle, and upper bands of the 5GHz Unlicensed
National Information Infrastructure (UNII) bands.
• The WLAN device is 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
Division 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, CKIP, and AES encryption.
