G-3000H User's Guide
The 802.11b data rate and corresponding modulation techniques are shown in the table below.
The modulation technique defines how bits are encoded onto radio waves.

802.11g Wireless LAN Standard
The ZyAIR, complies with the 802.11g wireless standard and is also fully compatible with the
802.11b standard. This means an 802.11b radio card can interface directly with an 802.11g
device (and vice versa) at 11 Mbps or lower depending on range. 802.11g has several
intermediate rate steps between the maximum and minimum data rates. The 802.11g data rate
and modulation are as follows:.

Note: The ZyAIR 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.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between switches,
bridges or routers. It allows a bridge to interact with other (R)STP-compliant bridges in your
network to ensure that only one path exists between any two stations on the network.
WMM QoS
WMM (Wi-Fi MultiMedia) QoS (Quality of Service) allows you to prioritize wireless traffic
according to the delivery requirements of the individual and applications.
Certificates
The ZyAIR can use certificates (also called digital IDs) to authenticate users. Certificates are
based on public-private key pairs. Certificates provide a way to exchange public keys for use
in authentication.
