title: First transcontinental telephone call text: First transcontinental telephone call A telephone call, which for marketing purposes is claimed to be the first transcontinental telephone call, occurred on Jan. 25, 1915, a day timed to coincide with the Panama–Pacific International Exposition celebrations. However, the transcontinental telephone line was first completed on June 17, 1914, and successfully first voice tested in July 1914. A 1998 U.S. postage stamp commemorates the completion of the line in 1914. The original long distance telephone network actually started in 1885, in New York City. By 1892 this line reached Chicago. After introducing loading coils in 1899, the long distance line continued title: Long-distance calling text: showcased until early 1915, as a promotion for the upcoming Panama–Pacific International Exposition in San Francisco in the spring of the same year. On January 25, 1915, Alexander Graham Bell ceremonially sent the first transcontinental telephone call from 15 Dey Street in New York City, which was received by his former assistant Thomas A. Watson at 333 Grant Avenue in San Francisco. This process, nevertheless, involved five intermediary telephone operators and took 23 minutes to connect by manually "patching in" the route of the call. On November 10, 1951, the first direct dial long-distance telephone call in North America was title: Mobile phone text: Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation (0G) services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service. These 0G systems were not cellular, supported few simultaneous calls, and were very expensive. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using title: History of mobile phones text: for voice and data communications. 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 June 17th 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 area and only a few available channels in urban areas. The introduction 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 title: Mobile telephony text: little or no consequence," leading it not to attempt to commercialize the invention. The invention earned Joel induction into the National Inventors Hall of Fame in 2008. The first call on a handheld mobile phone was made on April 3, 1973 by Martin Cooper, then of Motorola to his opposite number in Bell Labs who were also racing to be first. Bell Labs went on to install the first trial cellular network in Chicago in 1978. This trial system was licensed by the FCC to ATT for commercial use in 1982 and, as part of the divestiture arrangements for the
