We move a step down in the abstraction level and look at system types. So far we have avoided the specific knowledge of the system type for the engine and simulation. This gives us power. Since the engine and simulation has been implemented without knowing the specificity of a system to simulate, we can now extend the system with new types. As long as the general system interface remains the same, adding new system types would not affect the engine or simulation at all!

Figure 307 is the Model-module code for a RadioSystem – the most abstracted version of a system. These definitions would therefore apply to any specific system but in the abstract definition there is no mention of Generic or Cellular specific properties. So generally speaking a RadioSystem has a frequency which is a distribution. It has a Receiver and a Transmitter. And importantly it defines a Link between the transmitter and receiver.
