Detailed Description

This class is the subclass of MacLow to provide support for MAC extension (1) allows higher layer control data rate and tx power level.

Introspection did not find any typical Config paths.

If higher layer does not set, they will be determined by WifiRemoteStationManager of MAC layer; If higher layer sets tx parameters in non-adaptable mode, the data rate and tx power level will be used for transmission;. If higher layer sets tx parameters in adaptable mode, the data rate will be lower bound for the actual data rate, and the power level will be upper bound for the actual transmit power. (2) implements the feature described in Annex C : avoid transmission at scheduled guard intervals However, the feature is extended further here that the required transmit time is determined by MAC layer itself rather than PHY layer, which contains RTS/CTS, DATA and ACK time.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 640 bytes (on a 64-bit architecture).
