OID_DOT11_CURRENT_TX_POWER_LEVEL (Compact 2013)

3/26/2014

When queried, this OID requests that the miniport driver return the value of the IEEE 802.11 dot11CurrentTxPowerLevel management information base (MIB) object for the current PHY type on the 802.11 station.

This MIB object specifies the power level of the current PHY type. Depending on the PHY type, this MIB object can be used to determine the receiver sensitivity requirements for the PHY’s clear channel assessment (CCA) mechanism.

The data type for this OID is a ULONG value from 1 through 8.

The current TX power level for the current PHY type use must be within the range of TX power levels that were previously specified by the miniport driver when it was queried by OID_DOT11_SUPPORTED_POWER_LEVELS.

If the miniport driver is operating in Extensible Station (ExtSTA) mode, the current PHY type is determined through the ExtSTA msDot11CurrentPhyID MIB object. This MIB object specifies the index of the current PHY type within the 802.11 station’s list of supported PHY types. For more information about msDot11CurrentPhyID, see OID_DOT11_CURRENT_PHY_ID.
