Wireless communications
The computer’s wireless communication function supports some wireless
communication 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) 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 all wireless 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 wireless functionality.
■ Always turn off wireless 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.
