Chapter 1 Getting to Know Your ZyAIR
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.
1.2.2.6 802.11g 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:.
1.2.2.7 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.
1.2.2.8 Limit the number of Client Connections
You may set a maximum number of wireless stations that may connect to the ZyAIR. This
may be necessary if for example, there is interference or difficulty with channel assignment
due to a high density of APs within a coverage area.
