Chapter 1 Overview
Role in a Wireless Network
Repeater Bridge
You can also use a bridge as a repeater. A repeater bridge is placed between two bridges to extend the
range of your infrastructure or to overcome an obstacle that blocks radio communication. The repeater
bridge may or may not be attached to a LAN segment.
The repeater forwards traffic between wired LAN segments by sending packets to another bridge.
Figure 1-4 shows a bridge set up as a repeater.
Figure 1-4 Repeater Bridge
You can set up a chain of repeater bridges, but throughput across the repeater chain will be quite low.
Because each repeater must receive and then re-transmit each packet on the same channel, throughput is
cut in half for each repeater you add to the chain. For example, throughput is halved for data sent from
workstation B to workstation A in Figure 1-4.
Rugged Access Point
The bridge has a metal housing, so you can install it in surroundings that would be too harsh for a bridge
or an access point with a plastic housing. The bridge must be protected from water, but it will operate in
extreme temperatures. Refer to the “Role in Radio Network” section on page 3-4 for instructions on
setting up the bridge as an access point. Figure 1-5 shows a bridge functioning as a rugged access point.
