Operating Basics

Wireless communications

The computer's wireless communication function supports both Wireless
LAN and Bluetooth devices.
All models are provided with Wireless Communication switch. 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 IEEE802.11 Wireless LAN standard
(Revision A, B or G).
Do not install or remove an optional memory module while Wake-up on
Wireless LAN is enabled.
The Wake-up on Wireless LAN function consumes power even when the
system is off. Leave the AC adaptor connected while using this feature.
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 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.
■
Wi-Fi Protected Access (WPA).
■
Wake-up on Wireless LAN (Intel module type).
■
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.
■
The Wake on Wireless function is effective only when it is connected
with AP. This function becomes invalid when the connection is cut.
