 Understanding digital communication systems is of great importance in many engineering and non-engineering fields, for example:
 \begin{itemize}
-	\item \textbf{Automation} -- 
-	\item \textbf{Medical Systems} -- 
-	\item \textbf{Transport} -- railway, air traffic
-	\item \textbf{Public Safety} --

-	\item \textbf{Energy Sector} -- 
+	\item \textbf{Automation} -- The components of an automation system are interconnected. There are bus systems like ProfiBus in machine control. Non-safety applications may use wireless systems (RFID in logistics, etc.).
+	\item \textbf{Medical Systems} -- Telemedicine requires broadband systems for communication between health care professionals or between a health care professional and a patient. Robotic surgery has tight requirements on latency and reliability.
+	\item \textbf{Transport} -- Public infrastructure (railway, air traffic) need safety systems. Aeronautical radio is the basis for air traffic management. Vehicles like high-speed trains, aircrafts or cars require communication devices on board so that their components can 
+	\item \textbf{Public Safety} -- Authorities and organizations responsible for safety (police, fire brigades, civil protection) must reliably exchange information to run their missions.
+	\item \textbf{Agriculture} -- Future agriculture uses sensors to observe soil parameters, vital signs of animals, etc. Weather forecasts would be impossible without communication technology (weather radar, weather satellites).
+	\item \textbf{Energy Sector} -- Smart grids rely on information exchange between energy producers and energy consumers. Communication technologies enable an efficient control of the power network.
