That first cell phone began a fundamental technology and communications market shift to making phone calls to a person instead of to a place. [6] [19] Bell Labs had introduced the idea of cellular communications in 1947, but their first systems were limited to car phones which required roughly 30 pounds (12 kg) of equipment in the trunk.

A man talks on his mobile phone while standing near a conventional telephone box, which stands empty. Enabling technology for mobile phones was first developed in the 1940s but it was not until the mid-1980s that they became widely available. By 2011, it was estimated in Britain that more calls were made using mobile phones than wired devices. [1]
Douglas H. Ring (March 28, 1907 in Montana – September 8, 2000 in Red Bank, New Jersey) was one of the Bell Labs engineers that invented the cell phone.The history of cellular phone technology began on December 11, 1947 with an internal memo written by Douglas H. Ring in which he proposed development of a cellular telephone system by AT&T. [1]
Two decades of evolution of mobile phones, from a 1992 Motorola DynaTAC 8000X to the 2014 iPhone 6 Plus. A mobile phone, or cell phone, [a] is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones (landline phones).
John Francis Mitchell (January 1, 1928 – June 9, 2009) was an American electronics engineer and president and chief operating officer of Motorola. [3] [4]Mitchell led the pioneering development and implementation of Motorola's mobile phone technology producing the first portable transistorized pager and cell phone.
1970: Amos E. Joel, Jr. of Bell Labs invented the "call handoff" system for "cellular mobile communication system" (patent granted 1972). 1970: British companies Pye TMC, Marconi-Elliott and GEC develop the digital push-button telephone, based on metal–oxide–semiconductor (MOS) integrated circuit (IC) technology.
