Content and background
The invention of wired telegraphy laid the foundation for the long-distance transmission of information. After Heinrich Hertz was able to prove the existence of electromagnetic waves in Karlsruhe in 1887, there was subsequently an enormous boost in the development of wired and then also wireless telegraphy. While wired telegraphy immediately gained widespread use, wireless mobile communications played a negligible role in the daily lives of people until the nineties of the twentieth century. It was not until the introduction of digital cellular mobile communications systems that a mass market developed whose growth prospects remain significant.
An important basis for the operation of mobile communications systems is the existence of landline networks that carry traffic over long distances. These networks transmit data via optical fibers, which dominate today's wide-area networks down to the access networks and, with their high bandwidths, enable individual subscribers to use applications with data rates in the double-digit gigabit/s range. In this context, the wireless network locally accesses the bandwidth resources provided by the fiber-optic networks and enables mobile connectivity for the user.
Communication networks therefore usually combine both wireless and wired components. Consequently, an interdisciplinary knowledge of the physical properties of mobile radio channels is required, as well as, for example, of antennas, optical fibers, transmitter and receiver principles, modulation schemes, access strategies, coding and encryption algorithms, and transport and control protocols. Thus, building on the mathematical-physical fundamentals, this field of specialization covers high-frequency engineering and electronics, communications engineering and optical communications.
