A mobile phone, cell phone or hand phone is an electronic device used to make mobile telephone calls across a wide geographic area, served by many public cells, allowing the user to be mobile. By contrast, a cordless telephone is used only within the range of a single, private base station, for example within a home or an office.A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network provided by a mobile network operator. The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing 2 kg.In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions grew from 12.4 million to over 4.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid.

Nokia

The predecessors of the modern Nokia were the Nokia Company (Nokia Aktiebolag), Finnish Rubber Works Ltd (Suomen Gummitehdas Oy) and Finnish Cable Works Ltd (Suomen Kaapelitehdas Oy).Nokia's history starts in 1865 when mining engineer Fredrik Idestam established a groundwood pulp mill on the banks of the Tammerkoski rapids in the town of Tampere, in southwestern Finland, and started manufacturing paper. In 1868, Idestam built a second mill near the town of Nokia, fifteen kilometres (nine miles) west of Tampere by the Nokianvirta river, which had better resources for hydropower production. In 1871, Idestam, with the help of his close friend statesman Leo Mechelin, renamed and transformed his firm into a share company, thereby founding the Nokia Company, the name it is still known by today

Samsung

In 1938, Lee Byung-chull (1910–1987) of a large landowning family in the Uiryeong county came to the nearby Daegu city and founded Samsung Sanghoe , a small trading company with forty employees located in Su-dong (now Ingyo-dong). It dealt in groceries produced in and around the city and produced noodles itself. The company prospered and Lee moved its head office to Seoul in 1947. When the Korean War broke out, however, he was forced to leave Seoul and started a sugar refinery in Busan as a name of Cheil Jedang. After the war, in 1954, Lee founded Cheil Mojik and built the plant in Chimsan-dong, Daegu. It was the largest woolen mill ever in the country and the company took on an aspect of a major company.Samsung diversified into many areas and Lee sought to establish Samsung as an industry leader in a wide range of enterprises, moving into businesses such as insurance, securities, and retail. Lee placed great importance on industrialization, and focused his economic development strategy on a handful of large domestic conglomerates, protecting them from competition and assisting them financially. He later banned several foreign companies from selling consumer electronics in South Korea in order to protect Samsung from foreign competition.
