Motorola DynaTAC

DynaTAC is a series of cellular telephones manufactured by Motorola, Inc. from 1983 to 1994. The first model, the 8000x, received FCC certification in 1983,[1] and became the first cell phone to be offered commercially when it went on sale on 6 March 1983. It offered 30 minutes of talk time and 8 hours of standby, and a LED display for dialling or recall of one of 30 phone numbers. It was priced at $3,995 in 1983. DynaTAC was an abbreviation of Dynamic Adaptive Total Area Coverage. Several models followed, starting in 1985 with the 8000s and continuing with periodic updates of increasing frequency until 1993's Classic II. Throughout, the DynaTAC was the canonical cell phone, and it became a regular feature in mass media, first as a symbol of wealth and futurism, and later as a quaint throwback when its era had ended. The DynaTAC was swiftly made obsolete in most roles by the much smaller Motorola MicroTAC when it was first introduced in 1989, and by the time of the Motorola StarTAC it was already an anachronism. The first cellular phone was the culmination of efforts began at Bell Labs, which first proposed the idea of a cellular system in 1947, and continued to petition the FCC for channels through the 1950s and 1960s, and research conducted at Motorola. In 1960, John F. Mitchell,[2][3][4] an electrical engineer who graduated from the Illinois Institute of Technology, became Motorola's chief engineer for its mobile communication products. Mitchell oversaw the development and marketing of the first pager to use transistors. Motorola had long produced mobile telephones for automobiles, that were large and heavy and consumed too muc

power to allow their use without the automobile's engine running. Mitchell's team, which included Martin Cooper, developed portable cellular telephony, and Mitchell was among the Motorola employees granted a patent for this work in 1973; the first call on the prototype was completed, reportedly, to a wrong number.[5][6] While Motorola was developing the cellular phone itself, during 1968-1983, Bell Labs worked on the system called AMPS, which became the first cellular network in the U.S. Motorola and others designed cell phones for that and other cellular systems. 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. The DynaTAC's retail price, $3,995 ($9322 in present-day terms[7]), ensured that it would not become a mass-market item; by 1998, when Mitchell retired, cellphones and associated services made up two thirds of Motorola's $30 billion in revenue.[8] On October 13, 1983, David D Meilahn placed the first commercial wirelessa call on a DynaTAC from his 1983 Mercedes 389SL 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. The call, made at Soldier Field in Chicago, is considered by many as 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.
