Wireless communications
The computer’s wireless communication function supports both Wireless
LAN and Bluetooth devices.
Some models are provided with a Wireless communication switch, and only
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 the IEEE802.11 Wireless LAN standard
(Revision A, B or G).
■ Theoretical maximum speed of 54Mbps for IEEE 802.11a or 802.11g
■ Theoretical maximum speed of 11Mbps for IEEE 802.11b
■ Frequency Channel Selection of 5GHz for IEEE 802.11a or 2.4GHz for
802.11b/g
■ Roaming over multiple channels
■ Card power management
If you use a storage device such as an optical drive or hard disk drive
connected to a 16-bit PC Card, you might experience the following
problems with the operation of the modem:
■ The modem speed is slow or communication is periodically interrupted.
■ Skips or jumps may be noted in sound.
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.
■ The Wake-up on Wireless LAN function is effective only when it is
connected with an Access Point. This function becomes invalid when
the connection is broken.
