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]
1 November 1960: The Bell System begins testing its push-button phone, starting with service in Findlay, Ohio. [39] 1960: Bell Labs conducts extensive field trial of an electronic central office in Morris, Illinois, known at the Morris System. 1960s: Bell Labs developed the electronics for cellular phones; 1961: Initiation of Touch-Tone service ...
W. Rae Young in 2006. William Rae Young, Jr. (October 30, 1915 – March 7, 2008) was one of the Bell Labs engineers that invented the cell phone. The history of cellular phone technology began on December 11, 1947 with a Bell Labs internal memo written by Douglas H. Ring describing the idea of Rae Young of the hexagonal cell concept for a cellular mobile telephone system.
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.
CBSI developed the first automated cellular service activation systems (referred to as “provisioning systems”) now used globally in retail locations to remotely and instantly activate cellular phones. Also, at CBSI, Harris served as one of three FCC committee members challenged to develop intersystem roaming protocols.
