Who is the inventor of the first phonsel, and who is the first vendor who became to be the birthplace of the uterus and multimedia communication media in the grip of this ......?
Martin Cooper is the inventor of mobile phones in use for more than half the world's population. The first handset born in 1973 with the help of Motorola team weighing two kilograms. When he suffered on the streets of New York and make the first phone call from a prototype cell phone, he never imagined it would be successful homemade device at any time.
To produce the first mobile phone, the Motorola require the equivalent cost with US $ 1 million. "In 1983, the portable phone worth US $ 4 thousand (Rp36 million) with the equivalent of US $ 10 thousand (Rp90 million) today," he said.
Cooper said that his team faced the challenge of how to put all the ingredients into a mobile phone for the first time. But ultimately industrial designers have done a super job and engineers completed the first mobile device 2kg.
"Materials that are very important for the first mobile phone with battery weight is 4 or 5 times than existing mobile phones today. Time 20 minutes of battery life, but it is not a problem because users will not use it for that," he said.
After producing mobile phones, the biggest challenge is adapting infrastructure, to support mobile phone calls. "The challenge is to create a network with only requires 3 MHz spectrum, on par with the five TV channels which gave rise to the whole world," he added. He and his team hope that one day everyone can have their own handsets.
"The fact we joked by saying in the future, when someone is born then have to sign a telephone number, and if it does not answer the phone call, then the user will die. We do not have a shadow of a 35-year half-human on earth will have a mobile phone and they give cuma2 to others, "he said.
