Operating Basics

Wireless communications

The computer’s wireless communication function supports both Wireless

LAN and Bluetooth devices.
Bluetooth is 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).
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: 5 GHz, Revision B/G: 2.4 GHz)

Roaming over multiple channels

Card Power Management

Wired Equivalent Privacy (WEP) data encryption, based on the 128 bit

encryption algorithm.

Advanced Encryption Standard (AES) data encryption.

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 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. Performance of

these functions may vary depending on the format of data transmitted.
