title: History of mobile phones text: retroactively when referring to the earlier systems. First automatic analog cellular systems deployed were NTT's system first used in Tokyo in 1979, later spreading to the whole of Japan, and NMT in the Nordic countries in 1981. The first analog cellular system widely deployed in North America was the Advanced Mobile Phone System (AMPS). It was commercially introduced in the Americas in 13 October 1983, Israel in 1986, and Australia in 1987. AMPS was a pioneering technology that helped drive mass market usage of cellular technology, but it had several serious issues by modern standards. It was unencrypted and easily title: History of mobile phones text: for voice and data communications. In the United States, engineers from Bell Labs began work on a system to allow mobile users to place and receive telephone calls from automobiles, leading to the inauguration of mobile service on June 17th 1946 in St. Louis, Missouri. Shortly after, AT&T offered "Mobile Telephone Service". A wide range of mostly incompatible mobile telephone services offered limited coverage area and only a few available channels in urban areas. The introduction of cellular technology, which allowed re-use of frequencies many times in small adjacent areas covered by relatively low powered transmitters, made widespread adoption of title: 1990s text: trade zone consisting of Canada, Mexico, and the United States Prominent assassinations, targeted killings, and assassination attempts include: North America Asia Europe South America The 1990s were a revolutionary decade for digital technology. Between 1990 and 1997, individual personal computer ownership in the US rose from 15 to 35%. Cell phones of the early-1990s and earlier ones were very large, lacked extra features, and were used by only a few percent of the population of even the wealthiest nations. Only a few million people used online services in 1990, and the World Wide Web had only just been invented. The title: History of mobile phones text: of the iconic early commercial cell phones such as the Motorola DynaTAC Analog AMPS were eventually superseded by Digital AMPS (D-AMPS) in 1990, and AMPS service was shut down by most North American carriers by 2008. In February 1986 Australia launched its Cellular Telephone System by Telecom Australia. Peter Reedman was the first Telecom Customer to be connected on 6 January 1986 along with five other subscribers as test customers prior to the official launch date of 28 February. In the 1990s, the 'second generation' mobile phone systems emerged. Two systems competed for supremacy in the global market: the European title: Digital Revolution text: 1989, 15% of all U.S. households owned a computer, and nearly 30% of households with children under the age of 18 owned one. By the late 1980s, many businesses were dependent on computers and digital technology. Motorola created the first mobile phone, Motorola DynaTac, in 1983. However, this device used analog communication - digital cell phones were not sold commercially until 1991 when the 2G network started to be opened in Finland to accommodate the unexpected demand for cell phones that was becoming apparent in the late 1980s.
