Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11EDCATableAIFSN
OID (numeric): 1.2.840.10036.2.4.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute shall specify the number of slots, after a SIFS duration, that the QSTA, for a particular AC, shall sense the medium idle either before transmitting or executing a backoff. The default value for this attribute is 1) 7, if dot11EDCATableIndex is 1, 2) 3, if dot11EDCATableIndex is 2 3) 2, otherwise.
What is dot11EDCATableAIFSN?
Sets the number of idle slots (after SIFS) a QSTA must sense before transmitting or backing off, for the Access Category identified by dot11EDCATableIndex; voice/video ACs default to a shorter AIFSN (2) than background (7). Shortening this value for latency-sensitive traffic is exactly how EDCA gives voice and video priority access over bulk data.
Examples
