  • Channel: The channel attached to this PHY
  • ChannelSettings: Tuple {channel number, channel width (MHz), PHY band, primary20 index} describing the settings of the operating channel. The primary20 index is the index of the primary 20 MHz channel within the operating channel (0 indicates the 20 MHz subchannel with the lowest center frequency) and is only valid if the width of the operating channel is a multiple of 20 MHz. 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.

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.

Parameters

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).
