Wireless communications
The computer’s wireless communication function supports both Wireless
LAN and Bluetooth devices.
Some models are equipped with both Wireless LAN and Bluetooth functions.
Wireless LAN
The Wireless LAN is compatible with other LAN systems based on Direct
Sequence Spread Spectrum/Orthogonal Frequency Division Multiplexing
radio technology that complies with the IEEE802.11 Wireless LAN standard.
■ Frequency Channel Selection of 5GHz for IEEE 802.11a or n 2.0
■ Frequency Channel Selection of 2.4GHz for 802.11b/g or n 2.0
■ 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
■ If an error occurs during authentication, you will be returned to the
Select Tiles screen.
■ If authentication was successful, but an authentication error
subsequently occurred during the login to Windows, you will be asked
to provide your account information.
The transmission speed over the wireless LAN, and the distance over
which the wireless LAN can reach, may vary depending on surrounding
electromagnetic environment, obstacles, access point design and
configuration, 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.
