42 Chapter 1 Getting To Know Your ZyXEL Device
Note: The ZyXEL 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.
Wi-Fi Protected Access and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification standard.
Key differences between WPA and WEP are user authentication and improved data
encryption. WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger
encryption, authentication and key management than WPA.
Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol
(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also
uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication code Protocol (CCMP) to offer stronger encryption.
Antenna
The ZyXEL Device is equipped with one 2-dBi fixed antenna to provide clear radio signal
between the wireless stations and the access points.
Output Power Management
Output power management is the ability to set the level of output power. There may be
interference or difficulty with channel assignment when there is a high density of APs within a
coverage area. In this case, you can lower the output power of each access point, thus enabling
you to place access points closer together.
Wireless LAN MAC Address Filtering
Your ZyXEL Device can check the MAC addresses of wireless stations against a list of
allowed or denied MAC addresses.
1.3 Application
The ZyXEL Device is the ideal high-speed Internet access solution. In addition, the ZyXEL
Device allows wireless clients access to your network resources.
1.3.1 Protected Internet Access
The ZyXEL Device provides protection from attacks by Internet hackers. By default, the
firewall blocks all incoming traffic from the WAN. The firewall supports TCP/UDP
inspection and DoS (Denial of Services) detection and prevention, as well as real time alerts,
reports and logs.
