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:
Note: Your device may be prone to RF (Radio Frequency) interference from other 2.4
GHz devices such as microwave ovens, wireless phones, Bluetooth enabled
devices, and other wireless LANs.
IEEE 802.11g+ Wireless LAN
Your device supports IEEE 802.11g+ to allow any ZyXEL WLAN devices that also support
IEEE 802.1g+ to associate with the ZyXEL Device at higher transmission speeds than with
standard IEEE 802.11g.
External Antenna
The ZyXEL Device is equipped with an attached antenna to provide a clear radio signal
between the wireless stations and the access points.
Wireless LAN MAC Address Filtering
Your device can check the MAC addresses of wireless stations against a list of allowed or
denied MAC addresses.
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.
