Operating Basics
Wireless communications
The computer’s wireless communication function supports Wireless LAN
devices.
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.
Supported features. It supports the following features:
■ Theoretical maximum speed: 54Mbps (IEEE802.11a, 802.11g)
■ Theoretical maximum speed: 11Mbps (IEEE802.11b)
■ Frequency Channel Selection
(Revision A/Turbo Mode:5 GHz, Revision B/G: 2.4 GHz)
■ Roaming over multiple channels
■ Card Power Management
■ Wired Equivalent Privacy (WEP) data encryption,
based on the 152 bit encryption algorithm (Atheros module type).
■ Wired Equivalent Privacy (WEP) data encryption,
based on the 128 bit encryption algorithm (Intel module type).
■ Advanced Encryption Standard (AES) data encryption,
based on 256 bit encryption algorithm (Atheros module type).
■ Wi-Fi Protected Access (WPA).
Security
■ TOSHIBA strongly recommend that you enable WEP (encryption)
functionality, otherwise your computer will be open to illegal access by
an outsider using a wireless connection. If this occurs, the outsider may
illegally access your system, eavesdrop, or cause the loss or
destruction of stored data.
■ TOSHIBA is not liable for the loss of data due to eavesdropping or
illegal access through the 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
TM function, your client and access point must support the
corresponding feature. Performance of these functions may vary
depending on the format of data transmitted.
