Glossary
Association
Each root unit or repeater in the radio network contains an
Association Table that controls the routing of packets between
the Access Point (AP) and the wireless devices. The Association
Table maintains entries for all the nodes situated below the
Aironet Access Point in the radio network including repeaters
and client nodes.
End Node
A fixed or mobile wireless device that communicates with an AP
to access the wired LAN.
Radio Network
The radio network is the communications system that combines
Access Points, mobile nodes, and fixed nodes. Access Points
within the radio network can be either root units, which are
physically wired to the LAN backbone, or can act as wireless
repeaters that extend the range of a root AP. Other wireless
devices serve as fixed nodes or mobile client nodes.
Parent/Child Node
Refers to the relationships between nodes in the wireless
infrastructure. The complete set of relationships is sometimes
described as a Network Tree. For example, the Access Point (at
the top of the tree) would be the parent of the end nodes.
Conversely, the end nodes would be the children of the Access
Point.
Repeater
A repeater is an Access Point that extends the radio range of the
infrastructure. A repeater is not physically attached to the wired
LAN, but communicates via radio to another Access Point, which
is either a root unit or another repeater.
Root Unit
The root unit is an Access Point that is located at the top, or
starting point, of a wireless infrastructure. A root unit provides
the physical connection to the wired LAN and contains
