When queried, the OID_DOT11_SUPPORTED_OFDM_FREQUENCY_LIST OID requests that the miniport driver returns the list of channel center frequencies that the 802.11 station can operate with.
The data type for this OID is the DOT11_SUPPORTED_OFDM_FREQUENCY_LIST structure.
You can use this OID to indicate to the operating system any frequency channels that should be scanned for conformance with performance specifications. The operating system does not use these OIDs during routine operation of the 802.11 station.
The OID MIB object is only valid for the following PHY types:
- Orthogonal frequency division multiplexing (OFDM) PHY.
- High-throughput (HT) 802.11n PHY or very high-throughput (VHT) 802.11ac PHY when operating in the 5-GHz band.
If the current PHY type is not set to dot11_phy_type_ofdm, dot11_phy_type_ht, or dot11_phy_type_vht, the miniport driver must fail the query request by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function.
Support for this OID is optional, unless the station reports to the operating system that it supports the dot11_phy_type_ofdm PHY type. In this case support for this OID is mandatory.
If the miniport driver is operating in Extensible Station (ExtSTA) mode, the current PHY type is determined through the ExtSTA msDot11CurrentPhyID management information base (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.
