Chapter 1 Getting To Know Your ZyXEL Device

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.

The ZyXEL Device is equipped with one 3dBi fixed antenna to provide clear radio signal 
between the wireless stations and the access points. 

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless 
network to help keep network communications private.

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.

Your ZyXEL Device can check the MAC addresses of wireless stations against a list of 
allowed or denied MAC addresses.

Here are some example uses for which the ZyXEL Device is well suited.
