This method is a pure virtual method that must be implemented by the sub-class.
This allows different types of WifiRemoteStationManager to respond differently,
station | the station that we successfully sent RTS |
ctsSnr | the SNR of the CTS we received |
ctsMode | the WifiMode the receiver used to send the CTS |
rtsSnr | the SNR of the RTS we sent |

In contrast to rate, power levels do not depend on the remote station. The levels depend only on the physical layer of the device.
