Wireless Communications; Wireless Lan - Toshiba Qosmio G20-102 User Manual

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) and Turbo Mode.
Supported features. It supports the following features:
Theoretical maximum speed: 54Mbps (IEEE802.11a, 802.11g)
Theoretical maximum speed: 11Mbps (IEEE802.11b)
Theoretical maximum speed:
108Mbps (Turbo Mode; Atheros module type)
Frequency Channel Selection
(Revision A/Turbo Mode:5 GHz, Revision B/G: 2.4 GHz)
Roaming over multiple channels
Card Power Management
Atheros Super G
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).
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

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