This table holds the specification of the antenna
connected to the 802.11 interfaces of an
infrastructure device like an AP or Bridge.
The table gets populated when the administrator
configures the 802.11 interface with information
about the antenna connected to it.
This table has a sparse dependent relationship
with ifTable defined in IF-MIB. There exists an
entry in this table corresponding to the entry for
each dot11 interface found in ifTable. This table is
not applicable to virtual dot11 interfaces.
