On April 3, 1973, Martin Cooper stood on a sidewalk on sixth avenue in Manhattan with a device the size of a brick and made the first public call from a cell phone to one of the men he’d been competing with to develop the device. “I’m calling you on a cell phone, but a real cell phone, a personal, handheld, portable cell phone,” Cooper, then an engineer at Motorola, said on the phone to Joel Engel, head of AT&T-owned Bell Labs.
” After Cooper’s first call, manufacturing issues and government regulation slowed the progress bringing the phone to the public, he said. For example, Cooper recalls the Federal Communications Commission, an agency at which he now serves as an adviser, struggling to sort out how to split up radio channels to ensure competition. It would take a decade for a version of that DynaTAC phone to hit the market, for a hefty $3,900.
