Motorola DynaTAC
The DynaTAC 8000X by Motorola was the world's first commercial mobile phone . DynaTAC was short for Dyn amic A daptive T otal A rea C overage. It used the AMPS cellular standard at the time .
In 1973, Motorola began development under Martin Cooper and chief designer Rudy Krolopp , which 10 years later received FCC approval in the form of the Dynatac 8000X on September 21, 1983 . It weighed 794 g and measured 33 × 4.5 × 8.9 cm. At that time it still cost 3,995 US dollars (adjusted for inflation currently corresponds to 10,235 US dollars), offered a call duration of around an hour and could store 30 numbers. Nevertheless, just one year later (1984) 300,000 people had the forefather of the modern cell phone. A similar model is the Motorola International 3200 known as "Bone" .
