G08C - Definition
This subclass covers:
In the context of transmission systems for measured values, control signals or the like:
Relationship between large subject matter areas
H04B covers the transmission of information-carrying signals, in general, the transmission being independent of the nature of the information. G08C refers to transmission systems specially adapted for measured values, control signals or the like. H04L covers transmission of signals having been supplied in digital form and includes telegraphic communication. The borderline between H04L and G08C lie on whether subject mater is digital transmission techniques per se (H04L) or the transmission system combined with measurement or control (G08C).
