DOT11_OFDM_PHY_ATTRIBUTES structure

Important  The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.
 
The DOT11_OFDM_PHY_ATTRIBUTES structure defines the attributes specific to an orthogonal frequency division multiplexing (OFDM) PHY type.

Syntax

typedef struct DOT11_OFDM_PHY_ATTRIBUTES {
  ULONG uFrequencyBandsSupported;
} DOT11_OFDM_PHY_ATTRIBUTES, *PDOT11_OFDM_PHY_ATTRIBUTES;

Members

uFrequencyBandsSupported

The frequency bands in which the PHY is capable of operating. Frequency bands are defined for:

  • Unlicensed national information infrastructure (U-NII) bands.
  • Conference of European Post and Telecommunication (CEPT) bands.
  • Japan 5 GHz bands.
The frequency bands supported by the PHY are defined through the following bitmask:
Bit Description
0 Can operate in the lower (5.15-5.25 GHz) U-NII band.
1 Can operate in the middle (5.25-5.35 GHz) U-NII band.
2 Can operate in the upper (5.725-5.825 GHz) U-NII band.
3 Can operate in CEPT B (5.47-5.7253 GHz) band.
4 Can operate in the lower Japan (5.15-5 5.25 GHz) band.
5 Can operate in the Japan 5.0 (5.03-8 5.091 GHz) band.
6 Can operate in the Japan 4.9 (4.9-5.0GHz) band.

Remarks

The miniport driver defines the attributes of a PHY on the 802.11 station through the DOT11_PHY_ATTRIBUTES structure, and formats the OFDMAttributes member as a DOT11_OFDM_PHY_ATTRIBUTES structure. The miniport driver must only do this if the PHY defined by the DOT11_PHY_ATTRIBUTES structure is an OFDM PHY type.

Requirements
