OID_802_11_RTS_THRESHOLD

When set, the OID_802_11_RTS_THRESHOLD OID requests that the miniport driver set the request to send (RTS) threshold of the underlying NIC to a specified value. This value specifies the packet size beyond which the IEEE 802.11 wireless LAN invokes its RTS/CTS procedure.

For non-zero values, the RTS threshold value represents a number of bytes. Packets that exceed the specified RTS threshold trigger the RTS/CTS procedure. The NIC transmits packets with lengths less than or equal to the threshold without using RTS/CTS. An RTS threshold value of 0 indicates that the NIC must transmit all packets using RTS/CTS.

The minimum threshold value is 0, and the maximum is 2347. If an invalid threshold value is specified, the miniport driver returns NDIS_STATUS_INVALID_DATA.

When queried, this OID requests that the miniport driver return the RTS threshold setting. If the miniport driver does not support this OID, it returns NDIS_STATUS_NOT_SUPPORTED.

The data type for this OID is defined as follows:



        typedef ULONG NDIS_802_11_RTS_THRESHOLD;
