Using the Wireless LAN
✍
In some countries, using WLAN products may be restricted by the local regulations (e.g. limited number of channels). Therefore, before activating the
WLAN function, read the
Safety Regulations
carefully.

WLAN uses the IEEE 802.11a
*
/b/g standard or the IEEE 802.11n
*
draft standard, which specifies the type of technology used. The 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
