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 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.
■ Frequency Channel Selection of 5GHz for IEEE 802.11a or/and
IEEE802.11n
■ Frequency Channel Selection of 2.4GHz for IEEE 802.11b/g or/and
IEEE802.11n
■ Roaming over multiple channels
■ Card power management
■ Wired Equivalent Privacy (WEP) data encryption based on an 128-bit
encryption algorithm
■ Wi-Fi Protected Access (WPA)
■ Do not use the Wireless LAN (Wi-Fi), Bluetooth or Wireless WAN
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, Bluetooth or Wireless WAN operation.
■ Turn Wi-Fi, Bluetooth and Wireless WAN 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 or Wireless
WAN functionality.
■ Always turn off Wi-Fi or Bluetooth or Wireless WAN 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.
