Who is the Inventor of the Mobile Phone System?

The first mobile phone introduced to the public on 3 April 1973 in New York. At that time Motorola's mobile phone is still a prototype and tested by Martin Cooper (now chairman, CEO, and co-founder of ArrayComm Inc) while he was still a general manager of Motorola's Communications Systems Division. It was the incarnation of his vision for personal wireless communications, distinct from cellular car phones.

"People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are, unfettered by the infamous copper wire. It is that freedom we sought to vividly demonstrate in 1973," said Martin Cooper.

That first call, placed to Cooper's rival Joel S Engel at AT&T's Bell Labs from the streets of New York City, caused a fundamental technology and communications market shift toward the person and away from the place in the New York area. And Cooper told Engel that he already invented the first phone that does not require wires. The idea of ​​the proposed type by Cooper is a communication tool that is small, easy to carry and flexible.

This mobile phone is known as the first generation (1-G). At that time, Cooper is considered strange by people who saw him talking on the phone all the way. Someone even stopped moving just looking at him. Then Cooper invited journalists to a press conference and demonstration in front of journalists to prove that the communication technology at the time actually developing and wireless communication is not a hoax.

Motorola began marketing its first mobile phones in 1983 called the Motorola DynaTAC with 0.4 kg of weight. Since Motorola released their first mobile phone, there was a remarkable development in the mobile phone industry, namely the emergence of mobile phones with smaller sizes with a variety of additional advanced features, such as music player, camera, video call and Wi-Fi. Furthermore, now comes Smartphone that has powered with touch screen technology. And mobile phone is the greatest invention of this century that changed all of human perception in communication. *** [SEPTI | FROM VARIOUS SOURCES | PIKIRAN RAKYAT 25102012]
