virtual WifiMode ns3::WifiPhy::GetMode ( uint32_t mode ) const

pure virtual

The WifiPhy::GetNModes() and WifiPhy::GetMode() methods are used (e.g., by a WifiRemoteStationManager) to determine the set of transmission/reception modes that this WifiPhy(-derived class) can support - a set of WifiMode objects which we call the DeviceRateSet, and which is stored as WifiPhy::m_deviceRateSet.

It is important to note that the DeviceRateSet is a superset (not necessarily proper) of the OperationalRateSet (which is logically, if not actually, a property of the associated WifiRemoteStationManager), which itself is a superset (again, not necessarily proper) of the BSSBasicRateSet.

mode	index in array of supported modes

		bool	isShortPreamble,

Public method used to fire a MonitorSniffer trace for a wifi packet being received. Implemented for encapsulation purposes.

Parameters

packet	the packet being received
channelFreqMhz	the frequency in MHz at which the packet is received. Note that in real devices this is normally the frequency to which the receiver is tuned, and this can be different than the frequency at which the packet was originally transmitted. This is because it is possible to have the receiver tuned on a given channel and still to be able to receive packets on a nearby channel.
channelNumber	the channel on which the packet is received
rate	the PHY data rate in units of 500kbps (i.e., the same units used both for the radiotap and for the prism header)
isShortPreamble	true if short preamble is used, false otherwise
signalDbm	signal power in dBm
noiseDbm	noise power in dBm
