Detailed Description

802.11 PHY layer model

This PHY implements a model of 802.11a.

The model implemented here is based on the model described in "Yet Another Network Simulator", (http://cutebugs.net/files/wns2-yans.pdf).

This PHY model depends on a channel loss and delay model as provided by the ns3::PropagationLossModel and ns3::PropagationDelayModel classes, both of which are members of the ns3::YansWifiChannel class.

Config Paths

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

/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phy/$ns3::YansWifiPhy

Attributes

EnergyDetectionThreshold: The energy of a received signal should be higher than this threshold (dbm) to allow the PHY layer to detect the signal.
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: -96

WifiModeList ns3::YansWifiPhy::m_deviceRateSet

private

This vector holds the set of transmission modes that this WifiPhy(-derived class) can support.

In conversation we call this 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 this vector looking for WifiMode objects for which WifiMode::IsMandatory() is true.

A quick note is appropriate here (well, here is as good a place as any I can find)...

In the standard there is no text that explicitly precludes production of a device that does not support some rates that are mandatory (according to the standard) for PHYs that the device happens to fully or partially support.

This approach is taken by some devices which choose to only support, for example, 6 and 9 Mbps ERP-OFDM rates for cost and power consumption reasons (i.e., these devices don't need to be designed for and waste current on the increased linearity requirement of higher-order constellations when 6 and 9 Mbps more than meet their data requirements). The wording of the standard allows such devices to have an OperationalRateSet which includes 6 and 9 Mbps ERP-OFDM rates, despite 12 and 24 Mbps being "mandatory" rates for the ERP-OFDM PHY.

Now this doesn't actually have any impact on code, yet. It is, however, something that we need to keep in mind for the future. Basically, the key point is that we can't be making assumptions like "the Operational Rate Set will contain all the mandatory rates".
