Description
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. REFERENCE [1] Part 11.
