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.
WPA2 WPA 2 is a wireless security standard that defines stronger
encryption, authentication and key management than WPA.
