1876 (March 10) | Antecedent | Scottish-born Alexander Graham Bell, the inventor of the telephone, makes the first phone call.[1] | United States |
1960 | The first fully automated mobile telephone is introduced in Sweden. The system, known in Swedish as Mobiltelefonisystem A (MTA), allows for automated connection from a rotary handset (that’s the circular dialing knob to me and you) mounted within a car, but requires an operator to forward calls.[2][2] | Sweden | |
1962 | Mobiltelefonisystem A (MTA) is replaced by Mobiltelefonisystem B (MTB), which uses transistorized mobile sets. This system would last until 1983.[2] | Sweden | |
1973 | The first mobile call is made by a Motorola employee. The phone weighs over a kilo and takes 10 hours to charge.[1] | ||
1979 | 1G, the first generation of wireless telephone technology, is launched in Japan by Nippon Telegraph and Telephone (NTT). It is the first commercially automated cellular network.[1] "initially in the metropolitan area of Tokyo. Within five years, the NTT network had been expanded to cover the whole population of Japan and became the first nationwide 1G network." | Japan | |
1981 | "In 1981, the Nordic Mobile Telephone (NMT) system simultaneously launched in Denmark, Finland, Norway and Sweden. NMT was the first mobile phone network to feature international roaming." | ||
