Maidenhead: McGraw-Hill International (UK). p.23. ISBN 0-335-21761-3. On October 13, 1983, David D. Meilahn placed the first commercial wireless call on a DynaTAC from his 1983 Mercedes-Benz 380SL to Bob Barnett, former president of Ameritech Mobile Communications, who then placed a call on a DynaTAC from inside a Chrysler convertible to the grandson of Alexander Graham Bell, who was in Germany for the event. [12] The call, made at Soldier Field in Chicago, is considered to be a major turning point in communications. Later, Richard H. Frenkiel, the head of system development at Bell Laboratories, said about the DynaTAC: "It was a real triumph; a great breakthrough." [13] Publications [ edit ]

Whether you call them dumb phones or feature phones, the best non-smartphones focus on providing only the most essential functions, just like the Nokia you had over 10 years ago. The first automatic analog cellular systems ever deployed were NTT's system first used in 1979 for car phones in Tokyo (and later the rest of the country of Japan), and the cellular systems released by Comvik in Sweden in September, [41] [42] NMT in the other Nordic countries in October of 1981.

In the United States, engineers from Bell Labs began work on a system to allow mobile users to place and receive telephone calls from automobiles, leading to the inauguration of mobile service on 17 June 1946 in St. Louis, Missouri. Shortly after, AT&T offered Mobile Telephone Service. A wide range of mostly incompatible mobile-telephone services offered limited coverage areas and only a few available channels in urban areas. As calls were transmitted as unencrypted analog signals, anyone with radio equipment that could receive those frequencies could eavesdrop. The commercial introduction (in Japan in 1979) of cellular technology, which allowed re-use of frequencies many times in small adjacent areas covered by relatively low-powered transmitters, made widespread adoption of mobile telephones economically feasible. and Cellular radio Information".
