a channel to interconnect ns3::YansWifiPhy objects.
This class is expected to be used in tandem with the ns3::YansWifiPhy class and supports an ns3::PropagationLossModel and an ns3::PropagationDelayModel. By default, no propagation models are set; it is the caller's responsibility to set them before using the channel.
ns3::YansWifiChannel is accessible through the following paths with Config::Set and Config::Connect:
No TraceSources are defined for this type.
Group: Wifi
Size of this type is 96 bytes (on a 64-bit architecture).

This method is scheduled by Send for each associated YansWifiPhy.
The method then calls the corresponding YansWifiPhy that the first bit of the PPDU has arrived.
receiver | the device to which the packet is destined |
ppdu | the PPDU being sent |
txPower | the TX power associated to the packet being sent |

sender | the PHY object from which the packet is originating. |
ppdu | the PPDU to send |
txPower | the TX power associated to the packet |
This method should not be invoked by normal users. It is currently invoked only from YansWifiPhy::StartTx. The channel attempts to deliver the PPDU to all other YansWifiPhy objects on the channel (except for the sender).
