Introduction
Wireless LAN Some computers 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 A, B or G).
■ Theoretical maximum speed of 54Mbps for
IEEE 802.11a or 802.11g
■ Theoretical maximum speed of 11Mbps for
IEEE 802.11b
■ Frequency Channel Selection of 5GHz for
IEEE 802.11a or 2.4GHz for 802.11b/g
■ Roaming over multiple channels
■ Card power management
■ Wired Equivalent Privacy (WEP) data
encryption based on an 128-bit encryption
algorithm
■ Wi-Fi Protected Access (WPA) support
■ Advanced Encryption Standard (AES) data
encryption
■ Wake-up on Wireless LAN support
■ The numerical 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 Transmit Rate (at X Mbit/s) is the theoretical maximum speed
under the IEEE802.11 (a/b/g) standard. The actual transmission speed
will be lower than the theoretical maximum speed.
■ The Wake-up on Wireless LAN function is effective only when it is
connected with an Access Point. This function becomes invalid when
the connection is broken.

communication
switch
This switch turns the Wireless LAN and
Bluetooth functions on and off. Please note that
all models are provided with a Wireless
communication switch and some models are
equipped with both Wireless LAN and Bluetooth
functionality.
