[edit] History

The first handheld mobile phone call had been in 1973, on a prototype model. The first mobile phone base station was installed atop New York's 50-story Alliance Capital Building. This first base station could serve no more than 30 subscribers by connecting them to ground communication lines. Dr. Martin Cooper made the first call from this mobile telephone.^{[citation needed]}

This phone call took place in the morning on April 3, 1973. Cooper dialed the number to Joel Engel, chief of the research department at Bell Laboratories. The call ushered in a revolution in the world of communications. Later Richard Frenkel, the head of system development at Bell Laboratories, said about the Dyna-Tac: "It was the true triumph".^{[citation needed]}

[edit] Description

Several prototypes were made between 1973 and 1983. The product accepted by the FCC weighed 28 ounces and was 10 inches 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) End (End)

Pwr (Power) Lock (Lock) Vol (Volume)

The display utilized red LEDs, and was severely limited in what information it could show. The battery allowed for a call up to 35 minutes, after which it was necessary to charge the telephone up to more than 10 hours.^{[citation needed]}

[edit] Portability

While it might be considered unwieldy by today's standards, at the time it was considered revolutionary, because mobile telephones were bulky affairs installed in vehicles. 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.^{[citation needed]}
