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 (of which an instance exists in objects of this class) deals with rates beyond the first 8.
