My History....
The history of mobile phones charts the development of devices which connect wirelessly to the public switched telephone network. The transmission of speech by radio has a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony.
Before the devices that are now referred to as a mobile phone existed, there were some precursors. The development of mobile telephony began in 1918 with tests of wireless telephony on military trains between Berlin and Zossen.[1] In 1924, public trials started with telephone connection on trains between Berlin and Hamburg.[1] In 1925, the company Zugtelephonie A. G. is founded to supply train telephony equipment[1] and in 1926 telephone service in trains of the Deutsche Reichsbahn and the German mail service on the route between Hamburg and Berlin is approved [1] and offered to 1st class travelers.[2]
In 1926 the artist Karl Arnold created a visionary cartoon about the use of mobile phones in the street, in the picture „wireless telephony“, published in the German satirical magazineSimplicissimus.
