1st Generation Cellular Phone
Many countries launched the first generation of cellular telephone systems which included the NIT, AMPS, SACS, RT MI, C-Net, and Radio com 2000 tecnologies.
The first commercial launch was by NET in Tokyo around 1979. In 1981 the NMT system was introduced in Denmark, Finland, Norway and Sweden. In the US, the first handheld mobile phone was the Motorola_Dyna 8000X , which entered the market in 1983. Mobile phones began to proliferate through the 1980s with the introduction of "cellular" phones based on cellular networks with multiple base stations located adjacent to each other. Unlike previous cellular technology, this era saw the introduction of protocols for the automated continuity of calls even if they are made between two cell. At this time analog transmission was in use in all systems. Mobile phones were somewhat larger than current ones, and at first, all were designed for permanent installation in vehicles (hence the term car phone). Later, these bulky units were converted for use as "transportable" phones, with sizes as big as a briefcase. Motorola introduced the first truly portable, handheld phone.
