OID_DOT11_FREQUENCY_BANDS_SUPPORTED (Compact 2013)

When queried, this OID requests that the miniport driver return the IEEE 802.11 dot11FrequencyBandsSupported MIB object for the current PHY type on the 802.11 station.

This MIB object specifies the frequency bands in which the orthogonal frequency division multiplexing (OFDM) PHY can operate. 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 data type for this OID is a ULONG value, which defines the supported frequency bands through one of the bitmasks in the following table:

Bit

Description

0

Capable of operating in the lower (5.15-5.25 GHz) U-NII band

1

Capable of operating in the middle (5.25-5.35 GHz) U-NII band

2

Capable of operating in the upper (5.725-5.825 GHz) U-NII band

3

Capable of operating in CEPT B (5.47-5.7253 GHz) band

4

Capable of operating in the lower Japan (5.15-5.25 GHz) band

5

Capable of operating in the Japan 5.0 (5.03-5.091 GHz) band

6

Capable of operating in the Japan 4.9 (4.9-5.0GHz) band

The dot11FrequencyBandsSupported MIB object is valid for only the OFDM PHY type. If the current PHY type is not set to dot11_phy_type_ofdm, the miniport driver must fail a query of OID_DOT11_FREQUENCY_BANDS_SUPPORTED by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function.

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.
