Introduction
Bluetooth
Some computers in this series offer Bluetooth
wireless communication functionality which
eliminates the need for cables between
electronic devices such as computers and
printers. When implemented, Bluetooth provides
a fast, reliable and secure means to achieve
wireless communication in a small space.
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 of 54Mbps for
IEEE802.11a 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 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.
