Description

The WIFI_DEVICE_CAPABILITIES structure describes a WiFiCx device's capabilities.

Members

Size

The sum (in bytes) of the sizes of all contained elements.

HardwareRadioState

Specifies whether the radio is enabled by hardware. Valid values are 0 (disabled) and 1 (enabled).

SoftwareRadioState

Specifies whether they radio is enabled by software. Valid values are 0 (disabled) and 1 (enabled).

FirmwareVersion[MAX_FIRMWARE_VERSION_LENGTH]

The firmware version.

ActionFramesSupported

Specifies whether sending and receiving action frames is supported. Valid values are 0 (not supported) and 1 (supported).

NumRxStreams

The supported number of RX spatial streams.

NumTxStreams

The supported number of TX spatial streams.

Support_eCSA

Specifies whether eCSA is supported. Valid values are 0 (not supported) and 1 (supported).

MACAddressRandomization

Specifies whether the adapter supports MAC address randomization. Valid values are 0 (not supported) and 1 (supported).

MACAddressRandomizationMask

A bit mask that specifies for each address bit whether it can be randomized (0) or should keep the same value as the permanent address (1). The default is all zeros.

BluetoothCoexistenceSupport

A WDI_BLUETOOTH_COEXISTENCE_SUPPORT enum that defines the supported level of Wi-Fi - Bluetooth coexistence.

SupportsNonWdiOidRequests

Specifies non-WDI OID support. Valid values are:

FastTransitionSupported

Specifies whether the Fast Transition is supported. Valid values are 0 (not supported) and 1 (supported).

MU_MIMOSupported

Specifies whether Mu-MIMO is supported. Valid values are 0 (not supported) and 1 (supported).

BSSTransitionSupported

Specifies if 802.11v BSS transition is supported. Valid values are 0 (not supported) and 1 (supported).

SAEAuthenticationSupported

Specifies if the device supports SAE authentication. Valid values are 0 (not supported) and 1 (supported).

MBOSupported

Specifies if the device supports Multiband Operation (MBO). Valid values are 0 (not supported) and 1 (supported).

BeaconReportsImplemented

Specifies if the adapter implements beacon report measurements. Valid values are 0 (the adapter does not implement beacon report measurements) and 1 (the adapter implements its own 11k beacon report).

NumRadios

The number of radios. NumRadios is equal to the number of connections on different channels that the device can simultaneously Rx and Tx.

Remarks

Call WIFI_DEVICE_CAPABILITIES_INIT to initialize this structure and fill in its Size field. Then call WifiDeviceSetDeviceCapabilities to report device capabilities to WiFiCx.
