April 3, 1973: Motorola Calls AT&T ... by Cell
1973: Martin Cooper of Motorola uses the first portable handset ... to make the first cellphone call ... to his rival at Bell Labs. Rub it in.
If you wanted to make a mobile-phone call in those days, you might have a radiophone in your car. You'd need to spend thousands of dollars, stash about 30 pounds of equipment in your trunk and install a special antenna.
Bell Laboratories (then the research division of AT&T and now part of Alcatel-Lucent) had conceptualized cellular communications in 1947. But it was locked in a competition with Motorola in the '60s and '70s to go truly portable.
