OID_DOT11_HOP_TIME
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.
When queried, the OID_DOT11_HOP_TIME object identifier (OID) requests that the miniport driver return the value of the IEEE 802.11 dot11HopTime management information base (MIB) object for the current PHY type on the 802.11 station.
The dot11HopTime MIB object defines the time, in microseconds, that the physical media dependent (PMD) sublayer of the current PHY type requires to change from channel 2 to channel 80.
Note Support for OID_DOT11_HOP_TIME is mandatory if the NIC supports the dot11_phy_type_fhss PHY type. For more information about how the miniport driver specifies its list of supported PHY types, see OID_DOT11_SUPPORTED_PHY_TYPES.
The data type for OID_DOT11_HOP_TIME is a ULONG value.
The IEEE 802.11-2012 standard defines the value of the dot11HopTime MIB object to be 224.
The dot11HopTime MIB object is valid for only the frequency-hopping spread spectrum (FHSS) PHY type. If the current PHY type is not set to dot11_phy_type_fhss, the miniport driver must fail the query request 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.
Note A Native 802.11 miniport driver that is designed to run on the Windows Vista or Windows Server 2008 operating systems must always reset this 802.11 MIB OID to its default value. This is the case regardless of the value of the bSetDefaultMIB member of the DOT11_RESET_REQUEST structure. This requirement applies to a miniport driver that, in a call to the NdisMSetMiniportAttributes function, sets MiniportAttributes -> Native_802_11_Attributes -> Header -> Revision to NDIS_MINIPORT_ADAPTER_802_11_ATTRIBUTES_REVISION_1.
