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.

The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network. 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.
Martin Cooper, a former general manager for the systems division at Motorola, led a team that produced the DynaTAC 8000X, the first commercially available cellular phone small enough to be easily carried, and made the first phone call from it. Martin Cooper was the first person to make an analog cellular mobile phone call on a prototype in 1973.
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).
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.
1988: First transatlantic fiber optic cable TAT-8, carrying 40,000 circuits; 1990: analog AMPS was superseded by Digital AMPS. 1991: the GSM mobile phone network is started in Finland, with the first phone call in Tampere. [45] 1993: Telecom Relay Service available for the disabled; 1994: The IBM Simon becomes the first smartphone on the market.
This phone supposedly had 0.5 kg weight. Kupriyanovich proposed the device to serve more customers and named it a correllator. [1] [2] [3] In 1961, Leonid Kupriyanovich presented a pocket automatic radio phone that could fit in the palm of a hand. This pocket mobile phone weighed only 70 g and had an 80 km operating distance.
The device was an immediate success at the show and Canova found himself on the front of the money section of USA Today, pictured holding the phone. It was released under the name Simon in August 1994 [ 2 ] and patented by Canova and other team members in 1995 with a priority date of 13 November 1992. [ 3 ]
