This MIB is intended to be implemented on all
        802.11 based Access Points and Wireless Bridges
        that need to participate in radio environment
        diagnosis.  The devices mentioned above may house
        any one of the 802.11a/802.11b/802.11g standard-
        based radio interfaces in them for data
        communication in the form of radio waves.  The
        administrator, through the NMS, temporarily alters
        the power and channel configurations of an 802.11
        radio interface and the transmits power levels of
        the associated clients, if any, by setting
        appropriate values to the objects of this MIB to
        perform activities like discovering neighboring APs,
        measuring strength of the signals as received from
        other APs, studying RF interference levels at
        various APs, characterizing APs' coverage etc.
        These changes to the radio interface and the clients'
        configuration through this MIB are temporary and
        won't be retained across reloads.
        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.
        Mobile Node ( MN )
        A roaming 802.11 wireless device in a wireless
        network associated with an access point.
        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.
        Radio Diagnosis
        This process includes continuously monitoring the
        radio environment to discover new 802.11 stations,
        measure signal strengths, adapt robustly to
        interferers and provide a visualization of the radio
        topology to the administrator.
        The process by which an 802.11 client identifies and
        gets connected to its parent AP through which it
        gets the uplink to the wired network.  Note that
        the association happens at the MAC level and the AP
        holds the MAC addresses of all the clients for
        whom the AP provides uplink to the wired network.
        A client, at any point of time, can remain
        associated only with one AP.
        An instance of medium use for the purpose of passing
        protocol data units (PDUs) that may be used
        simultaneously, in the same volume of space, with
        other instances of medium use (on other channels) by
        other instances of the same physical layer (PHY), with
        an acceptably low frame error ratio due to mutual
        interference. Some PHYs provide only one channel,
        whereas others provide multiple channels.
        Beacons are short frames that are sent from Access
        Point to stations or station-to-station in order to
        organize and synchronize the wireless communication
        on the Wireless LAN.  Beacons serve to achieve
        time synchronization among clients, exchange SSID
        information, exchange information about data rates
        supported by the 802.11 devices etc.,
        Site Survey
        Site survey is done to discover the RF behavior,
        coverage and interference to decide the placement of
        WLAN infrastructure devices like Access Points and
        Wireless bridges to ensure that all the clients
        experience continually strong RF signal strength as
        they roam.
        This is a high speed physical layer extension to
        the 802.11 standard on the 5 GHz band.  Interfaces
        compliant to 802.11a support data rates upto 54Mbps
        and operate at 5.15-5.25, 5.25-5.35 and 5.725-5.825
        GHz Unlicensed National Information Infrastructure
        (U-NII) bands as regulated in the United States by
        the code of Federal Regulations, Title 47, Section
        15.407.  The radio uses the Orthogonal Frequency
        Division Multiplexing (OFDM) as the modulation
        scheme that enables higher speeds at 54Mbps.
        The 802.11b standard operates at 2.4GHz and is
        backward compatible with 802.11. An 802.11b
        system operates at 5.5 and 11 Mbps in addition to
        the 1 and 2 Mbps datarates specified by the 802.11
        standard.  802.11b uses a modulation technique known
        as Complementary Code Keying (CCK) which allows the
        higher data speeds.
        This is the most recently approved standard.  This
        standard specifies an operational frequency of
        2.4GHz and datarates upto 54Mbps.  802.11g systems
        are backward compatible with 802.11b systems because
        of the same operational frequencies.  Like 802.11a,
        802.11g uses the OFDM modulation scheme to achieve
        higher speeds.
