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.
Truth be told. Henry T. Sampson developed the technology (gamma-electric-cell) two years prior to make the cell phone even possible.
Important reminder! “Too many engineers are wrapped up in what they call technology and the gadgets, the hardware, and they forget that the whole purpose of technology is to make peoples’ lives better”
