Appendix A: Aironet Wireless LAN Adapter Overview

Saving: Max PSP, the most energy conserving mode; Fast

PSP, which sacrifices some power-saving in exchange for

data transfer speed; and CAM (Constant Awake Mode), in

which the client node never sleeps. Client nodes powered

from an AC line should use CAM.

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

(such as Ethernet or Token Ring) and contains configura-

tion information in its association table that covers all nodes

that access the wired network (backbone). All Access

Points directly attached to the wired LAN backbone are root

units.
