OID_DOT11_RTS_THRESHOLD (Compact 2013)

3/26/2014

When set, this OID requests that the miniport driver set the IEEE 802.11 dot11RTSThreshold management information base (MIB) object to the specified value.

When queried, this OID requests that the miniport driver return the value of the dot11RTSThreshold MIB object.

The dot11RTSThreshold MIB object specifies the maximum length that a MAC protocol data unit (MPDU) frame can have before the 802.11 station initiates the 802.11 request to send (RTS)/clear to send (CTS) handshake. For more information about the RTS/CTS handshake and RTS threshold, refer to Clause 9.2 of the IEEE 802.11-1999 standard.

The data type for this OID is a ULONG value that specifies the RTS threshold in bytes.

The value of the dot11RTSThreshold MIB object must be from 0 through 2347.

When OID_DOT11_RTS_THRESHOLD is set, the following actions apply to the 802.11 station:

  • The 802.11 station must use the new RTS threshold value on all MAC service data unit (MSDU) packets that are passed after the set request by the operating system to the miniport driver’s MiniportSendNetBufferLists function.
  • The 802.11 station can use the new RTS threshold value on all MSDU packets that are pending in the station’s transmit queue. Or, the 802.11 station can continue to use the old RTS threshold value for the pending MSDU packets.
  • The 802.11 station must not use the new RTS threshold value for any MPDU frames of the MSDU packet that the station is transmitting when OID_DOT11_RTS_THRESHOLD is set.

The default value for the dot11RTSThreshold MIB object is 2347. The miniport driver must set this MIB object to its default when one of the following occurs:
