1.3.6.1.4.1.9.9.626 |
| This MIB is intended to be implemented on Cisco's
WLAN devices that provide the wired uplink to wireless
clients through the high-throughput dot11 radios
compliant to the 802.11n specification.
The MIB describes the MAC layer parameters of the
802.11n compliant radio interfaces.
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.
A-MPDU
An aggregated format that consists of several MAC
Protocol Data Units being aggregated and transmitted
in one PHY Service Data Unit.
A-MSDU
An aggregated format that consists of several MAC
Service Data Units being aggregated and transmitted
in one MAC Protocol Data Unit.
Block-Ack
This refers to the acknowledgement done for all the
MPDUs in an A-MDPU.
Basic Service Set ( BSS )
The IEEE 802.11 BSS of an AP comprises of the
stations directly associating with the AP.
Dual CTS
Clear-To-Send control frame is sent by the receiver
in response to the Request-To-Send (RTS) control
frame from the sender to virtually reserve the
wireless medium for data transfer.
Dual CTS mechanism is used by the AP to reserve the
wireless medium for wireless devices that do not
support STBC.
Green Field
A mode of operation where high-throughput 802.11n
frames are transmitted without a legacy compatible
part.
Mobile Node ( MN )
A roaming 802.11 wireless device in a wireless
network associated with an access point. Mobile Node
and client are used interchangeably.
Modulation and Coding Scheme ( MCS )
This is a value that determines the modulation, coding and
number of spatial channels. Each scheme specifies the
modulation technique, coding rate , number of spatial
streams etc and the corresponding data rate.
Multiple Input Multiple Output ( MIMO )
This technique advocates sending and receiving data
communication signals through multiple antennas. MIMO
uses the multiple streams to transmit more information
and recombine the signal at the receiving end. This
brings more reliability and significant gain over the
traditional antenna systems.
Power Save Multi-Poll ( PSMP )
A MAC control frame that schedules the transmissions
and receptions of PSMP-enabled devices.
Phased Coexistence Operation ( PCO )
A BSS mode with alternating 20MHz and 40MHz phases of
operation controlled by a PCO AP.
Space-Time Block Coding ( STBC )
By this technique, a wireless device transmits several
copies of a data stream across a series of antennas
so that the receiver can use the various received
portions of the data signal to improve reliability of
data transfer.
Reduced Inter-Frame Space ( RIFS )
A time interval between multiple transmissions of a
single transmitter used to reduce overhead and
increase network efficiency.
TU
A measurement of time equal to 1024 microseconds.

station may transmit data. Each bit represents an
MCS index and corresponds to a particular data rate.
Each MCS shall be within the range from 0 to 127, and
shall be supported for receiving data.
This value is reported in transmitted Beacon, Probe
Request, Probe Response, Association Request,
Association Response, Reassociation Request and
Reassociation Response frames and is used to
indicate which MCS values shall be supported by all the
devices in the BSS. When this object is zeroed, it
indicates that the other stations in the BSS shall use
legacy data rates. |

1.3.6.1.4.1.9.9.626.1.1.1.1.2 |
| This object represents the operational power save
state of MIMO. The semantics are defined as follows.
'static' - The dot11 interface is operating in static
MIMO Power Save mode and hence, other stations
should not send MIMO packets destined to this dot11
interface.
'dynamic'- The interface switches out of the MIMO
Power Save mode to enable multiple receive chains
when an RTS is received and switches back to the
single receive-chain mode once the unicast
transmission of the MPDU is complete.
'mimo' - The dot11 interface always has multiple
receive-chains enabled and hence MIMO packets can
always be sent to this interface. |
