What company manufactured the world’s first cellular telephone?
Sorry, but the сorrect answer is:
Motorola was the first company to produce a working cell phone. By the time the DynaTAC (for “Dynamic Adaptive Total Area Coverage”) hit the market in 1984, it cost $3,995 ($9,209 in 2016 dollars). It weighed 28 ounces (790 g) and was 10 inches (25 cm) from bottom to top. Fully charging it took 10 hours, and it had to be recharged after 30 minutes of use. It was primarily a status symbol for the wealthy.
Mobile radiotelephones for automobiles had been in limited use in US cities for three decades before Motorola started manufacturing them in the 1960’s. Most of the equipment for one of these phones—in all, about 30 pounds (12 kg) of technology—had to be installed in the trunk of the car. Further, it drew its power from the car’s engine, which had to be running during use.
Once all the hand-held, portable technology was in place, the Motorola team assembled its first prototype, the DnyaTAC 800x, in 90 days. “The Brick” or “The Shoe”, as it was called, weighed 2.5 pounds (1.1 kg), and a 10-hour charge yielded only 20 minutes of talk time.
Bell Laboratories began planning the cell phone in 1947. Motorola started working to develop a cell phone in 1968. Between 1973 and 1983, the Motorola team developed its cell phone for market. It was not until 1993 that the company made its first profits on the technology, after having invested $100 million on it between 1973 and 1993.
