Getting to Know Your ZyAIR
1-3
Bridge/Repeater
A Bridge/Repeater link LED turns steady on green when your ZyAIR acts as a bridge, establishing up to six
wireless links with other APs. It turns steady on orange when your ZyAIR acts as a repeater, establishing
wireless links to two or more APs.
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.
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft. Key differences
between WPA and WEP are user authentication and improved data encryption.
Power over Ethernet (PoE)
Power over Ethernet (PoE) is the ability to provide power to your ZyAIR via an 8-pin CAT 5 Ethernet cable,
eliminating the need for a nearby power source. An injector or PoE device (not included) is also needed to
supply the Ethernet cable with power. This feature allows increased flexibility in the locating of your ZyAIR.
You only need to connect the external power adaptor if you are not using PoE. If you simultaneously use
both PoE and the external power adaptor, the ZyAIR will draw power from the PoE connection only. Refer
to the appendix for more information about PoE.
Figure 1-1 PoE Installation Example
802.11b Wireless LAN Standard
ZyAIR products containing the letter “B” in the model name, such as ZyAIR B-1000, ZyAIR B-1020,
comply with the 802.11b wireless standard.
The 802.11b data rate and corresponding modulation techniques are as follows. The modulation technique
defines how bits are encoded onto radio waves.
