Operating Basics
Wireless communications
The computer’s wireless communication function supports both Wireless
LAN and Bluetooth devices. Bluetooth provided with some models.
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 IEEE802.11 Wireless LAN standard
(Revision A, B or G) and Turbo Mode.
■ Theoretical maximum speed: 54Mbps (IEEE802.11g)
■ Theoretical maximum speed: 11Mbps (IEEE802.11b)
■ Theoretical maximum speed: 108Mbps (Turbo Mode)
■ Frequency Channel Selection (Revision B/G: 2.4 GHz)
■ Roaming over multiple channels
■ Card Power Management
■ Atheros Super G™ technology.
■ Wired Equivalent Privacy (WEP) data encryption, based on the 152 bit
encryption algorithm.
■ Advanced Encryption Standard (AES) data encryption, based on 256 bit
encryption algorithm.
■ Wi-Fi Protected Access (WPA).
Security
■ Be sure to enable WEP/WPA (encryption) function. Otherwise your
computer will allow the illegal access by outsider through Wireless LAN
to cause illegal intrusion, eavesdropping, and loss or destruction of
stored data. TOSHIBA strongly recommend the customer to enable the
WEP/WPA function.
■ TOSHIBA is not liable for the eavesdropping of data due to the use of
Wireless LAN and the damage thereof.
■ 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 (a/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.
