when was the first cell phone came out
History of mobile phones Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles.[20] Motorola was the first company to produce a handheld mobile phone. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs, his rival.[26][27] The prototype handheld phone used by Dr. Cooper weighed 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 re-charge.[28]
History of Nokia In 1979, the merger of Nokia and Salora resulted in the establishment of "Mobira Oy". Mobira developed mobile phones for the Nordic Mobile Telephone (NMT) network, called the "1G" and was the first fully automatic cellular phone system. It became commercially available in 1981.[21] In 1982, Mobira introduced its first car phone, the "Mobira Senator" for NMT â€“ 450 networks.[21]
