100 Years of Wireless Telephony in Germany: Experimental Radio Transmission from Eberswalde and Königs Wusterhausen

In this contribution, we examine the development of radio technology before 1921 and the emergence of the broadcasting concept during the World War I. We consider in detail the experiments in the transmitter stations located in Eberswalde and Königs Wusterhausen and numerous sources in order to assess the importance of their work. We also discuss the question of whether the medium of broadcasting (“Rundfunk”) started in Germany (or even in Europe) 100 years ago in one of these transmitter stations.

On the other hand, these political and legał changes associated with processes of liberalization in the world telecommunications have been described as the second fundamental factor.
