Detailed Description

The Supported Rates Information Element.

This class knows how to serialise and deserialise the Supported Rates Element that holds the first 8 (non-HT) supported rates.

The ExtendedSupportedRatesIE class deals with rates beyond the first 8.

Member Function Documentation

◆ DeserializeInformationField()

uint16_t ns3::SupportedRates::DeserializeInformationField ( Buffer::Iterator  start,
uint16_t  length 
)
overrideprotectedvirtual

Deserialize information (i.e., the body of the IE, not including the Element ID and length octets)

Parameters
startan iterator which points to where the information should be written.
lengththe expected number of bytes to read
Returns
the number of bytes read

Implements ns3::WifiInformationElement.

References m_rates, and NS_ASSERT.

◆ ElementId()

WifiInformationElementId ns3::SupportedRates::ElementId ( ) const
overridevirtual

Get the wifi information element ID.

Returns
the wifi information element ID

Implements ns3::WifiInformationElement.

Reimplemented in ns3::ExtendedSupportedRatesIE.

◆ GetInformationFieldSize()

uint16_t ns3::SupportedRates::GetInformationFieldSize ( ) const
overrideprotectedvirtual

Length of serialized information (i.e., the length of the body of the IE, not including the Element ID and length octets.

This is the value that will appear in the second octet of the entire IE - the length field - if the IE is not fragmented)

Returns
the length of serialized information

Returns
the rate in bps
