DOT11_DATA_RATE_MAPPING_ENTRY (Compact 2013)

3/26/2014

This structure defines a data rate supported by a PHY on the 802.11 station for transmit and receive operations.


typedef struct DOT11_DATA_RATE_MAPPING_ENTRY {
  UCHAR  ucDataRateIndex;
  UCHAR  ucDataRateFlag;
  USHORT  usDataRateValue;
} DOT11_DATA_RATE_MAPPING_ENTRY, *PDOT11_DATA_RATE_MAPPING_ENTRY;
ucDataRateIndex

The index value for the data rate contained in the usDataRateValue member. The value of the ucDataRateIndex member must be unique for each entry in the DataRateMappingEntries array.

This value is a bitmask as defined in the following table:

Bits

Description

0-6

The data rate index that contains a value from 2 through 127

7

This bit is not used and must be set to zero

ucDataRateFLag

The attributes of the data rate entry.

This value is a bitmask as defined in the following table:

Bits

Name

Description

0

DOT11_DATA_RATE_NON_STANDARD

If set, the entry is not a standard data rate defined in IEEE 802.11 standards

1-7

-

These bits are not used and must be set to zero

usDataRateValue

The data rate that is defined in units of 500 kilobits per second (Kbps), with a value from 0x0002 to 0xFFFF

For the IEEE 802.11 standard data rates, the miniport driver must set the ucDataRateIndex and usDataRateValue members to the same value.

The following table shows the IEEE 802.11 standard data rates, in units of megabits per second (Mbps), and the related values for the ucDataRateIndex and usDataRateValue members:
