Frames received from higher layers (typically the // MAC protocol) are transmitted on the radio channel, using the global // ChannelControl module. Frames received on the radio channel will have // their signal-noise ratio evaluated and passed up to the decider. // (It is the decider's task to determine whether the frame was received // correctly, and pass it up to the MAC layer). // // The receive/transmit channel (frequency) can be changed by sending // SnrEval a blank cMessage with PHY_C_CONFIGURERADIO as message kind, and // a PhyControlInfo object attached to it as control info, to hold the // new channel number. If the radio is currently transmitting, the channel // switch will actually take place after the transmission is completed. // // This component has been taken over from Mobility Framework 1.0a5. // //# FIXME merge docu with BasicSnrEval's simple SnrEval parameters: channelNumber: numeric const, // channel identifier debug : bool, // debug switch transmitterPower : numeric const, bitrate: numeric const, headerLength: numeric const, thermalNoise: numeric const, pathLossAlpha: numeric const, sensitivity: numeric const; gates: in: uppergateIn; // from higher layer protocol (MAC) out: uppergateOut; // to decider (decider connects to higher layer protocol, i.e. the MAC) in: radioIn; // to receive frames (AirFrame) on the radio channel endsimple
