By the 1960s, Bell Labs engineers Richard H. Frenkiel and Joel S. Engel developed the technology that could support Young's design of a cellular network. But as AT&T sought permission from the Federal Communications Commission (FCC) to develop a cellular network, a competitor made a bold and cheeky move in 1973.
That competitor was Martin Cooper, who at the time was an executive with Motorola, one of AT&T's competitors. Cooper led a team that designed the first practical cell phone. It was called the Motorola DynaTAC, and it still wasn't a tiny device -- it was 9 inches (22.9 centimeters) long and weighed 2.5 pounds (1.1 kilograms). Cooper decided to make one of the first cellular telephone calls to professional rival Joel Engel at Bell Labs. That's right -- the first cell phone was involved in what some might refer to as a prank call!
