Using the Wireless LAN
Using the Wireless LAN
The Wireless LAN (WLAN) allows your computer to connect to a network through a wireless connection.
The WLAN uses the following IEEE 802.11a/b/g/n standard, which specifies the type of technology used.
See the specifications to find out about the configuration of your computer.
WLAN standard Frequency band Remarks
IEEE 802.11a  5 GHz Available only on models compliant with the IEEE 802.11a/b/g/n standard.
IEEE 802.11b/g 2.4 GHz The IEEE 802.11g standard provides higher-speed communications than the IEEE 802.11b 
standard.
IEEE 802.11n 5  GHz/2.4  GHz On models compliant with the IEEE 802.11b/g/n standard, only the 2.4 GHz band can be used.

Notes on Using the Wireless LAN Function
General notes on using the wireless LAN function
❑In some countries or regions, using WLAN products may be restricted by the local regulations (e.g. limited number of 
channels).
❑The IEEE 802.11a standard and the IEEE 802.11n standard are not available on ad-hoc networks.
❑The 2.4 GHz band, with which wireless LAN devices work, is used by various devices. Although the wireless LAN devices 
use the technology to minimize radio interference from other devices that use the same band, such radio interference may 
cause slower communication speeds and narrower communication ranges or communication failures.
❑The communication speed and range may vary depending on the following conditions:
❑Distance between communication devices
❑Existence of obstacles between devices
❑Device configuration
❑Radio conditions
❑Ambient environment that includes existence of walls and materials of such walls
❑Software in use
❑Communications may be cut off depending on radio conditions.
❑Actual communication speed may not be as fast as the one displayed on your computer.
❑Deploying WLAN products compliant with different standards that use the same band on the same wireless network may 
reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed 
to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a 
different standard that uses the same band. When the communication speed is not as fast as expected, changing the 
wireless channel on the access point may increase the communication speed.

Note on the data encryption
The WLAN standard includes the encryption methods: Wired Equivalent Privacy (WEP), which is a security protocol, Wi-Fi 
Protected Access 2 (WPA2), and Wi-Fi Protected Access (WPA). Proposed jointly by the IEEE and Wi-Fi Alliance, both WPA2 
and WPA are specifications of standards based on interoperable security enhancements that increase the level of data 
protection and access control for existing Wi-Fi networks. WPA is designed to be forward compatible with the IEEE 802.11i 
specification. It utilizes the enhanced data encryption Temporal Key Integrity Protocol (TKIP) in addition to user authentication 
using 802.1X and Extensible Authentication Protocol (EAP). Data encryption protects the vulnerable wireless link between 
clients and access points. Besides that, there are other typical LAN security mechanisms to ensure privacy, such as: 
password protection, end-to-end encryption, virtual private networks, and authentication. WPA2, the second generation of 
WPA, provides stronger data protection and network access control and is also designed to secure all versions of 802.11 
devices, including 802.11b, 802.11a, 802.11g, and 802.11n standards, multi-band and multi-mode. In addition, based on the 
ratified IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of 
Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1X-based authentication. WPA2 
is backward compatible with WPA.

Using the BLUETOOTH Function
Using the BLUETOOTH Function
You can establish wireless communications between your computer and other BLUETOOTH® devices such as another 
computer or a mobile phone. You can transfer data between these devices without cables at a range of up to 10 meters in 
an open area.
BLUETOOTH Security
The BLUETOOTH wireless technology has an authentication function, which allows you to determine with whom you choose 
to communicate. With the authentication function, you can prevent any anonymous BLUETOOTH devices from accessing 
your computer.
The first time two BLUETOOTH devices communicate, a common passkey (a password required for authentication) should 
be determined for both devices to be registered. Once a device is registered, there is no need to re-enter the passkey.
✍The passkey can be different each time, but must be the same at both ends.
For certain devices, such as a mouse, no passkey can be entered.
