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

start	an iterator which points to where the information should be written.
length	the expected number of bytes to read

Returns: the number of bytes read

Implements ns3::WifiInformationElement.

References m_rates, NS_ASSERT, and two-ray-to-three-gpp-ch-calibration::start.

◆ 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.

Definition at line 207 of file supported-rates.cc.

References IE_SUPPORTED_RATES.

◆ 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

Implements ns3::WifiInformationElement.

◆ GetRate()

uint32_t ns3::SupportedRates::GetRate ( uint8_t i ) const

Return the rate (converted back to raw value) at the given index.

Parameters

i	the given index

Returns: the rate in bps

Here is the call graph for this function:

◆ SerializeInformationField()

void ns3::SupportedRates::SerializeInformationField ( Buffer::Iterator start ) const
