// This is the easiest nic to implement "real" network behaviour. It uses
// the CsmaMacLayer and the SnrDecider and SnrEval modules.
//
// The csma mac provides basic medium access and is used here to prevent a
// host from trying to send a message while it is still in receive mode.
//
// The phy layer modules allow to account for collision and take fading into
// account so that messages can actually be lost.
//
// IMPORTANT:<br> In order to work with the ChannelControl module the snrEval
// module has to be called "snrEval" in the ned file.
