Wireless communications
The computer’s wireless communication function supports both Wireless
LAN and Bluetooth devices.
Only some models are equipped with both Wireless LAN and Bluetooth
functions.
Wireless LAN
The Wireless LAN feature is not available on all models. Where present,
it supports the A,B, G and draft N standards but it 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.
■ Automatic Transmit Rate Select mechanism in the transmit range of
54, 48, 36, 24, 18, 12, 9 and 6 Mbit/s. (IEEE 802.11a/g)
■ Automatic Transmit Rate Select mechanism in the transmit range of
11, 5.5, 2 and 1 Mbit/s. (IEEE 802.11b)
■ 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, based on 128 bit
encryption algorithm.
■ Do not use the Wireless LAN (Wi-Fi) or Bluetooth functionalities near a
microwave oven or in areas subject to radio interference or magnetic
fields. Interference from a microwave oven or other source can disrupt
Wi-Fi or Bluetooth operation.
■ Turn Wi-Fi and Bluetooth functionalities off when near a person who
may have a cardiac pacemaker implant or other medical electric
device. Radio waves may affect pacemaker or medical device
operation, possibly resulting in serious injury. Follow the instruction of
your medical device when using any Wi-Fi or Bluetooth functionality.
■ Always turn off Wi-Fi or Bluetooth functionality if the computer is near
automatic control equipment or appliances such as automatic doors or
fire detectors. Radio waves can cause malfunction of such equipment,
possibly resulting in serious injury.
■ It may not be possible to make a network connection to a specified
network name using the ad hoc network function. If this occurs, the
new network(*) will have to be configured for all computers connected
to the same network in order to re-enable network connections.
■ * Please be sure to use new network name.
