IEEE802.11 Supported Rates element1 1 0-8 +----------+----------+----------------- |Element ID| Length | Supported Rates +----------+----------+----------------- Element ID: 1
The Supported Rates element specifies up to eight rates in the OperationalRateSet parameter, as described in the MLME-JOIN.request and MLME-START.request primitives, and zero or more BSS membership selectors. The Information field is encoded as 1 to 8 octets, where each octet describes a single Supported Rate or BSS membership selector. Within Beacon, Probe Response, Association Response, Reassociation Response, Mesh Peering Open, and Mesh Peering Confirm management frames, each Supported Rate contained in the BSSBasicRateSet parameter is encoded as an octet with the MSB (bit 7) set to 1, and bits 6 to 0 are set to the data rate, if necessary rounded up to the next 500kb/s, in units of 500 kb/s. Rates not contained in the BSSBasicRateSet parameter are encoded with the MSB set to 0, and bits 6 to 0 are set to the appropriate value. The MSB of each Supported Rate octet in other management frame types is ignored by receiving STAs. Within Beacon, Probe Response, Association Response, Reassociation Response, Mesh Peering Open, and Mesh Peering Confirm management frames, each BSS membership selector contained in the BSSMembershipSelectorSet parameter is encoded as an octet with the MSB (bit 7) set to 1, and bits 6 to 0 are set to the encoded value for the selector. A BSS membership selector that has the MSB (bit 7) set to 1 in the Supported Rates element is defined to be basic.- Since:

Method Detail

newInstance
public static Dot11SupportedRatesElement newInstance(byte[] rawData, int offset, int length) throws IllegalRawDataException
A static factory method. This method validates the arguments byByteArrays.validateBounds(byte[], int, int)
, which may throw exceptions undocumented here.- Parameters:
rawData
- rawDataoffset
- offsetlength
- length- Returns:
- a new Dot11SupportedRatesElement object.
- Throws:
IllegalRawDataException
- if parsing the raw data fails.
