Motorola became the first company to produce a handheld mobile phone. Handheld is a term which is used to describe something which is designed to be held in hand. In 1973, mobile telephony was limited to phones installed in cars and other vehicles.
The prototype handheld phone was first used by Dr. Martin Copper.
The weight of first handheld phone was 1.1 kg (2.42 lb) and measured 23 cm long, 13 cm deep and 4.45 cm wide.
The prototype offered a talk time of just 30 minutes and took 10 hours to recharge.
John F Mitchell, Motorola’s chief of portable communication products and Copper’s boss in in 1973, played a key role in advancing the development of handheld mobile phone equipment.
Mitchell successfully pressed Motorola to develop the wireless communication system products that would be small enough to use anywhere and share in the design of the cellular phone.
