Early devices were bulky, consumed large amounts of power, and the network supported only a few simultaneous conversations. Mobile telephones for automobiles became available from some telephone companies in the 1940s. Hand-held radio transceivers have been available since the 1940s. The Second World War made military use of radio telephony links. Then, 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 magazine Simplicissimus. In 1906, the English caricaturist Lewis Baumer published a cartoon in Punch magazine entitled "Forecasts for 1907" in which he showed a man and a woman in London's Hyde Park each separately engaged in gambling and dating on wireless telephony equipment. Karl Arnold drawing of public use of mobile telephonesįiction anticipated the development of real world mobile telephones. In 1925, the company Zugtelephonie AG was founded to supply train telephony equipment and, in 1926, telephone service in trains of the Deutsche Reichsbahn and the German mail service on the route between Hamburg and Berlin was approved and offered to first-class travelers. In 1924, public trials started with telephone connection on trains between Berlin and Hamburg. Beginning in 1918, the German railroad system tested wireless telephony on military trains between Berlin and Zossen. They were accused of fraud and the charge was then dropped, but they do not seem to have proceeded with production. In 1908, Professor Albert Jahnke and the Oakland Transcontinental Aerial Telephone and Power Company claimed to have developed a wireless telephone.

The first such devices were barely portable compared to today's compact hand-held devices, and their use was clumsy.ĭrastic changes have taken place in both the networking of wireless communication and the prevalence of its use, with smartphones becoming common globally and a growing proportion of Internet access now done via mobile broadband. While the transmission of speech by signal has a long history, the first devices that were wireless, mobile, and also capable of connecting to the standard telephone network are much more recent.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network. By 2011, it was estimated in Britain that more calls were made using mobile phones than wired devices. Enabling technology for mobile phones was first developed in the 1940s but it was not until the mid 1980s that they became widely available.
