Original Wi-Fi uses 13 channels in the ISM bands from 2412 MHz to 2484 MHz in 5 MHz steps. The radio channel between an amateur radio repeater and an amateur radio operator uses two frequencies often 600 kHz (0.6 MHz) apart. For example, a repeater that transmits on 146.94 MHz typically listens for a ham transmitting on 146.34 MHz.

Some theorists have raised doubts that the widely used characterization as a model of communication is correct and refer to it instead as "Lasswell's formula", "Lasswell's definition", or ...

Decoding is the reverse process of encoding: it happens when the signal is translated back into a message. [16] [17] [18]
Business Process Model and Notation (BPMN) is a standard for business process modeling that provides a graphical notation for specifying business processes in a Business Process Diagram (BPD), [3] based on a flowcharting technique very similar to activity diagrams from Unified Modeling Language (UML).

Annotated information flow diagram. An information flow diagram (IFD) is a diagram that shows how information is communicated (or "flows") from a source to a receiver or target (e.g. A→C), through some medium. [1]: 36–39 The medium acts as a bridge, a means of transmitting the information. Examples of media include word of mouth, radio ...
