Config Paths

ns3::WifiPhy is accessible through the following paths with Config::Set and Config::Connect:

  • "/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phy"
  • "/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phys/[i]"

Attributes

  • Antennas: The number of antennas on the device.
    • Set with class: ns3::UintegerValue
    • Underlying type: uint8_t 1:8
    • Initial value: 1
    • Flags: constructwriteread
  • CcaEdThreshold: The energy of all received signals should be higher than this threshold (dBm) in the primary channel to allow the PHY layer to declare CCA BUSY state.
    • Set with class: ns3::DoubleValue
    • Underlying type: double -1.79769e+308:1.79769e+308

If the standard for this object has not been set yet, the value of this attribute is saved and will be used to set the operating channel when the standard is configured. If the PHY band is left unspecified, the default band for the configured standard is used. If the channel width and the channel number are both 0, the default channel width for the configured standard and band are used. If the channel number is 0, the default channel number for the configured standard, band and channel width is used.Note that the channel width can be left unspecified (0) if the channel number uniquely identify a frequency channel for the given standard and band.

Public method used to fire a MonitorSniffer trace for a wifi PSDU being received.

Implemented for encapsulation purposes. This method will extract all MPDUs if packet is an A-MPDU and will fire tracedCallback. The A-MPDU reference number (RX side) is set within the method. It must be a different value for each A-MPDU but the same for each subframe within one A-MPDU.

Parameters
psduthe PSDU 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.

◆ m_phyEntities

std::map<WifiModulationClass, Ptr<PhyEntity> > ns3::WifiPhy::m_phyEntities
protected

This map holds the supported PHY entities.

The set of parameters (e.g. mode) that this WifiPhy(-derived class) can support can be obtained through it.

When it comes to modes, in conversation we call this set the DeviceRateSet (not a term you'll find in the standard), and it is a superset of standard-defined parameters such as the OperationalRateSet, and the BSSBasicRateSet (which, themselves, have a superset/subset relationship).

Mandatory rates relevant to this WifiPhy can be found by iterating over the elements of this map, for each modulation class, looking for WifiMode objects for which WifiMode::IsMandatory() is true.

◆ m_phyRxPayloadBeginTrace

TracedCallback<WifiTxVector, Time> ns3::WifiPhy::m_phyRxPayloadBeginTrace
private

The trace source fired when the reception of the PHY payload (PSDU) begins.

This traced callback models the behavior of the PHY-RXSTART primitive which is launched upon correct decoding of the PHY header and support of modes within. We thus assume that it is sent just before starting the decoding of the payload, since it's there that support of the header's content is checked. In addition, it's also at that point that the correct decoding of HT-SIG, VHT-SIGs, and HE-SIGs are checked.
