Detailed Description

The Extended Supported Rates Information Element

This class knows how to serialise and deserialise the Extended Supported Rates Element that holds (non-HT) rates beyond the 8 that the original Supported Rates element can carry.

The SupportedRates class still records all the rates, and an instance of ExtendedSupportedRatesIE lies within SupportedRates.

Buffer::Iterator ns3::ExtendedSupportedRatesIE::Serialize ( Buffer::Iterator  start) const

This information element is a bit special in that it is only included if there are more than 8 rates.

To support this we override the Serialize and GetSerializedSize methods of WifiInformationElement.

Parameters
start
Returns
an iterator
