31.4.1 IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE
802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa) at
11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps
between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation
are as follows:
Association List This feature allows you to know which wireless stations are currently
associated with the ZyXEL Device. You can block the individual
wireless station in the association list screen from accessing the
ZyXEL Device.
WEP Encryption WEP (Wired Equivalent Privacy) encrypts data frames before
transmitting over the wireless network to help keep network
communications private.
Wi-Fi Protected Access Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i
security standard. Key differences between WPA and WEP are user
authentication and improved data encryption.
WPA2 WPA 2 is a wireless security standard that defines stronger
encryption, authentication and key management than WPA.
WDS Use the WDS (Wireless Distribution System) to secure the link
between the ZyXEL Device and other APs on your network.
At the time of writing, the ZyXEL Device only supports WDS links with
other ZyXEL Devices.
WMM QoS WMM (Wi-Fi MultiMedia) QoS (Quality of Service) allows you to
prioritize wireless traffic according to the delivery requirements of
individual services.
