Terminology

When conﬁguring your system, and when reading this

manual, keep in mind the following terminology:

Infrastructure

– The wireless infrastructure is the

communications system that combines Aironet Bridges,

mobile nodes and ﬁxed nodes. Aironet Bridges within the

infrastructure can be either root units, which are physically

wired to the LAN backbone, or can act as wireless repeat-

ers. Other RF enabled devices serve as ﬁxed nodes or

mobile nodes.

Root Unit

– The root unit is an Aironet Bridge that is

located at the top, or starting point, of a wireless infrastruc-

ture. The root unit provides the physical connection to the

wired LAN (such as Ethernet or Token Ring) and contains

conﬁguration information in its association table that covers

all nodes in the infrastructure.

Repeater

– A repeater is an Aironet Bridge that extends the

radio range of the infrastructure. A repeater is not physically

attached to the wired LAN, but communicates via radio to

another Bridge, which is either a root unit or another

repeater.

End Node

– A radio node that is located at the end of the

Network Tree.
