This MIB is intended to be implemented on 802.11
Access Points and Wireless Bridges to provide
information about the antennas connected to their
802.11 interfaces.  The NMS retrieves the configured
antenna parameters and uses it to calculate the
recommended radio settings to be applied to the Access
Points being managed to achieve optimum coverage and
throughput.

                   GLOSSARY

Access Point ( AP )

An entity that contains an 802.11 medium access
control ( MAC ) and physical layer ( PHY ) interface
and provides access to the distribution services via
the wireless medium for associated clients.

Wireless Bridge

An 802.11 entity that provides wireless connectivity
between two wired LAN segments and is used in point-
to-point or point-multipoint configurations.

Repeater-AP

A repeater is a 'wireless AP' that is attached to a
parent AP on an 802.11 primary port.  The Ethernet
port is disabled in a Repeater-AP.

Antenna

A passive device connected to the 802.11 interface
that is used for transmission and reception of the
radio signals.  Antennas transmit radio signals
in all directions (omnidirectional) or in a
particular direction(directional, high-gain).

Antenna Gain

The Antenna Gain is the measure of the amount of
amplification done on the input radio signal by
the antenna.  Amplification is done by virtue of
focussing the RF radiation into a tighter beam.
Antenna Gain is expressed as dBi units.

Attenuator

An attenuator circuit allows a known source of power
to be reduced by a predetermined factor usually
expressed as decibels.  This power reduction is
achieved by the attenuator without introducing
distortion.  An attenuator may be used in either
audio or radio signal circuits.
