typedef void(* ns3::WifiPhy::MonitorSnifferRxCallback) (Ptr< const Packet > packet, uint16_t channelFreqMhz, WifiTxVector txVector, MpduInfo aMpdu, SignalNoiseDbm signalNoise)

TracedCallback signature for monitor mode receive events.

Parameters
packetthe packet being received
channelFreqMhzthe 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.

bool ns3::WifiPhy::DefineChannelNumber ( uint8_t  channelNumber,

Add a channel definition to the WifiPhy.

The pair (channelNumber, WifiPhyStandard) may then be used to lookup a pair (frequency, channelWidth).

If the channel is not already defined for the standard, the method should return true; otherwise false.

Parameters
channelNumberthe channel number to define
standardthe applicable WifiPhyStandard
frequencythe frequency (MHz)
channelWidththe channel width (MHz)
Returns
true if the channel definition succeeded

void ns3::WifiPhy::DoDispose ( void  )

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.
