Who Invented the Mobile Phone?
Who invented the mobile phone?
Dr Martin Cooper, a former general manager for the systems division at Motorola, is considered the inventor of the first modern portable handset. Cooper made the first call on a portable cell phone to his rival, Joel Engel, head of research at AT & T's Bell Laboratories on April 3, 1973.
Bell had introduced the idea of cellular communications in 1947 with their police car technology and had been racing to beat Motorola. But in the end Motorola was first to incorporate the technology into a portable device designed for use outside a vehicle.
The first really portable phone for the general public was produced in 1985 by Vodaphone. |
