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" published in WNS2 2006; an author-prepared version of this paper is at: https://hal.inria.fr/file/index/docid/78318/filename/yans-rr.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.
ns3::YansWifiPhy is accessible through the following paths with Config::Set and Config::Connect:

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 overridden 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.

| currentChannelWidth | channel width of the current transmission (MHz) |
Note: in order to properly model out of band transmissions for OFDM, the guard band has been configured so as to expand the modeled spectrum up to the outermost referenced point in "Transmit spectrum mask" sections' PSDs of each PHY specification of 802.11-2016 standard. It thus ultimately corresponds to the current channel bandwidth (which can be different from devices max channel width).
This method is only relevant for SpectrumWifiPhy.
