P-2802H(W)(L)-I Series User’s Guide

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:

Table 149   Wireless Features

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.
