RANDOM ORIGIN
CELL PHONES
AT&T first tested mobile phones for use in Swedish police cars in 1946. To develop the technology in the United States, they needed approval from the FCC—which controls the radio waves. The FCC didn’t think mobile phones would work and repeatedly turned down AT&T…until 1968, when AT&T unveiled its plan: offer phone service via many low-powered broadcast towers, each covering a “cell” of a few miles. As the car phone user traveled, calls passed from tower to tower uninterrupted.
Meanwhile, rival Motorola had secretly developed their own mobile phone, only theirs was a handheld model. (AT&T had concentrated on car phones.) In 1973 one of Motorola’s engineers, Dr. Martin Cooper, used a prototype to make the first cell phone call—to AT&T, to gloat. But AT&T was the first to get FCC approval, and had a trial cellular network set up in Chicago by 1978. The FCC authorized nationwide commercial cellular service in 1982 and just five years later there were over one million cell phone users in the United States.
