Introduction

Wireless LAN

Some models in this series are equipped with a

Wireless LAN mini-PCI card that is compatible

with other LAN systems based on Direct

Sequence Spread Spectrum/Orthogonal

Frequency Division Multiplexing radio technology

that complies with the IEEE 802.11 Standard

(Revision B or G), and Turbo Mode. Theoretical

maximum speed: 54Mbps (IEEE 802.11g)

■

Theoretical maximum speed: 11Mbps

(IEEE802.11b)

■

Theoretical maximum speed: 108Mbps

(Turbo Mode)

■

Frequency Channel Selection (2.4 GHz:

Revision B/G)

■

Roaming over multiple channels

■

Card Power Management

■

Atheros Super G

technology.

■

Wired Equivalent Privacy (WEP) data

encryption, based on 152 bit encryption

algorithm.

■

Advanced Encryption Standard (AES) data

encryption, based on 256 bit encryption

algorithm.

■

Wi-Fi Protected Access (WPA).

■

The numerical values for display are the theoretical maximums for

Wireless LAN standards. The actual values may differ.

■

The transmission speed over the Wireless LAN and the distance over

which Wireless LAN can reach may vary depending on surrounding

electromagnetic environment, obstacles, access point design and

configuration, and client design and software/hardware configurations.

The Transmit Rate (at X Mbit/s) is the theoretical maximum speed

under the IEEE802.11 (b/g) standard. The actual transmission speed

will be lower than the theoretical maximum speed. To use the Atheros
Super G

function, your client and access point must support the

corresponding feature. Performance of these functions may vary

depending on the format of data transmitted.
