Introduction

Wireless LAN

Some computers in this series are equipped with

a Wireless LAN 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 A, B or G).

Theoretical maximum speed:

54Mbps (IEEE802.11a, 802.11g)

Theoretical maximum speed:

11Mbps (IEEE802.11b)

Frequency Channel Selection

(5 GHz: Revision A / 2.4 GHz: Revision B/G)

Roaming over multiple channels

Card Power Management

Wired Equivalent Privacy (WEP) data

encryption, based on 152 bit encryption

algorithm (Atheros module type).

Wired Equivalent Privacy (WEP) data

encryption, based on 128 bit encryption

algorithm (Intel module type).

Wi-Fi Protected Access (WPA).

Advanced Encryption Standard (AES) data

encryption.

The values shown above 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 transmission rate described is the theoretical maximum speed as

specified under the appropriate standard - the actual transmission

speed will be lower than the theoretical maximum speed.
