DynaTAC is a series of cellular telephones manufactured by Motorola, Inc. from 1984 to 1994. The Motorola DynaTAC 8000X commercial portable cellular phone received approval from the U.S. FCC on September 21, 1983. A full charge took roughly 10 hours, and it offered 30 minutes of talk time. It also offered an LED display for dialing or recall of one of 30 phone numbers. It was priced at $3,995 in 1983, worth a modern-day price of nearly $10,000. 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 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 replaced 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 obsolete.
The first cellular phone was the culmination of efforts begun at Bell Labs, which first proposed the idea of a cellular system in 1947, and continued to petition the Federal Communications Commission (FCC) for channels through the 1950s and 1960s, and research conducted at Motorola. In 1960, electrical engineer John F. Mitchell, 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 much 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. 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 US. 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. Dr. Martin Cooper he was the first person to make a mobile phone call in 1973. Martin cooper is considered to be a key developer of the mobile phone. His was the first true portable phone. There were phones before this that were considered to be “car phones” but they were too big to be carried around. The Motorola DynaTAC 8000x was very large compared to phones today. This first cell phone was very expensive. The DynaTAC's retail price, $3,995 (about $9500 in present-day terms), 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. It wasn’t until later cell phones became smaller, more portable, and more affordable. In 1983 the first flip phone was designed. In 1993 cell phone companies realized that they could use cell phones for different things other than just calling. Developers in Europe came up with the text message. 2002 is when the first smart phone was developed. The smart phone could send and receive emails and messages but it needed a headset to work. The camera phone was also developed; the Sanyo Company developed the first camera phone. In 2007 Apple released the first iphone. This changed the cell phone industry, it had a touch screen and allowed users to do just about anything on it they could do on a computer. Every since then the cell phone industry has taken on a new level.
On October 13, 1983, David D Meilahn placed the first commercial wireless call on a DynaTAC from his 1983 Mercedes 380SL 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."
U.S. Patent 3,906,166, September 16, 1975 for a Radio Telephone System. the cell phone. Martin Cooper, Richard W. Dronsurth, Albert J. Leitich, Charles N. Lynk, James J. Mikulski, John F. Mitchell, Roy A. Richardson, and John H. Sangster.
N.B. Two names were botched in the original filing; Albert Leitich's surname was erroneously omitted, and Dr. Mikulski's first name was omitted. The original document was refiled by Motorola's legal staff, but has not yet been identified.
The seeds of the idea for a portable cell phone can be traced to Dr. James J. Mikulski, which were rejected by Mitchell for lack of sufficient business justifications. It is rumored that when John Mitchell suddenly recognized during an attempted phone call that his 400 MHz phone had inherent limitations, he immediately reversed his previous decision and championed the portable cell phone concept.
Several versions were made between 1973 and 1983. The product accepted by the FCC weighed 28 ounces (790 g) and was 10 inches (25 cm) high, not including its flexible "rubber duck" whip antenna. In addition to the typical 12-key telephone keypad, it had nine additional special keys:
- Rcl (recall)
- Clr (clear)
- Snd (send)
- Sto (store)
- Fcn (function)
- Pwr (power)
- Vol (volume)
The DynaTAC 8 Series, Classic, Classic II, Ultra Classic, and Ultra Classic II had a display with red LEDs; the DynaTAC International Series with green LEDs, and the DynaTAC 6000XL used a vacuum fluorescent display. These displays were severely limited in what information they could show. The battery allowed for a call of up to 60 minutes, after which, it was necessary to charge the phone up to 10 hours in a trickle charger or one hour in a fast charger, which was a separate accessory. While still retaining the DynaTAC name, the 6000XL was completely unrelated to the DynaTAC 8000 Series, in that it was a transportable phone meant for installation in a vehicle.
The DynaTAC Series was succeeded by the MicroTAC Series in 1989.
With the removal of analog network cells nearly all over the world, the DynaTAC models running on AMPS or other analog networks are mostly obsolete. Thus, they are more collectors' items than usable telephones. The International series, however, will still work, but only on GSM 900 cells.
The DynaTac 8000X, due to its resemblance in size and weight to a standard clay-fired brick, was nicknamed the brick phone by users, a term later applied to other brands as a contrast to smaller handsets appearing in the 1990s.
While it might be considered extremely unwieldy by modern standards, at the time, it was considered revolutionary because mobile telephones were bulky affairs installed in vehicles or in heavy briefcases. The DynaTAC 8000X was truly the first mobile telephone which could connect to the telephone network without the assistance of a mobile operator and could be carried about by the user.
In certain markets, a brass swivel antenna was one of the aftermarket accessories then available.
Motorola also offered a one-hour desktop charger, though the battery could get quite hot while charging at this accelerated rate. In some cases, this could cause major problems with the battery, occasionally short circuiting it and rendering it unusable.
Available, too, was a snug-fitting zippered leather case which covered the entire body of the phone and had a clear plastic front to make the user interface accessible. It featured a sturdy spring-steel belt clip and a small cutaway at the top to allow the antenna to protrude. Charging could still be performed with the cover on, but change of battery required its removal.
Dynatac relates to US phones, used on the Dynatac system in the US, not phones in use in the UK.
In popular culture
The DynaTAC has become associated with the 1980s in popular culture and has been heavily used in film and media set in that period.
The phone is well known for being used by Gordon Gekko in Wall Street, Zack Morris in Saved by the Bell, and Tommy Vercetti in Grand Theft Auto: Vice City. CJ from Grand Theft Auto: San Andreas can be seen using a phone similar to this in the game. It is also used by Patrick Bateman in American Psycho. Professional wrestling manager Paul E. Dangerously carried one of these phones with him to the ring and would often use it as an illegal weapon to help his wrestlers cheat.
