In 1986, Samsung was able to release its first built - in car phone, the SC - 100, but it was a failure due to the poor quality . In spite of unsuccessful result Ki Tae Lee, the then - head of the Wireless Development Team, decided to stay in the mobile business . He asked the company to buy ten Motorola mobile phones for benchmarking . After 2 years of R&D Samsung developed its first mobile phone (or "hand phone" in Korea), the SH - 100 in 1988 . It was the first mobile phone to be designed and manufactured in Korea . But the perception of mobile devices was very low and although Samsung introduced new models every year, each model sold only one or two thousand units . </P> <P> In 1993 it was decided that the development team should focus on improving connectivity due to specific mountain topography of Korea . They found the optimal length of a mobile phone antenna and developed a method of using gold to connect the point between the antenna and the communication circuits, thus significantly reducing resistance and enabling steadier wave conductivity . They also developed the wave - searching software that was specially designed for Korea's topography . </P>
