1st mobile in the world
1st mobile in the world In 1973, Motorola employees John F. Mitchell[11][12] and Martin Cooper exhibited the first portable cell phone, which weighed 4.4 pounds (2 kilograms).[2] Nippon Telegraph & Telephone (1G) launched the first automated commercial cellular network in Japan in 1979. The Nordic Mobile Telephone (NMT) system was simultaneously introduced in Denmark, Finland, Norway, and Sweden in 1981 as a result.[13] Later, in the early to mid-1980s, a number of other nations did likewise. While using analog cellular technology, these first-generation (1G) systems could allow many more simultaneous calls. The DynaTAC 8000x was the first portable mobile phone to be made available for purchase in 1983. Radiolinja introduced the second-generation (2G) GSM-based digital cellular technology in Finland in 1991.
