First Mobile Phone to Telephone.

A dozen years ago, if you remember, of course cell phones are still a luxury item.Even so, the look and performance of mobile phones is still quite standard. The shape is still simple, such a shape that resembles a banana. The feature can also be fairly unsophisticated, but sms and telephone, most sophisticated you can only play the game snake.
But technology allows mobile phones continues to grow. Not only in terms of shape which is much smaller, feature-rich mobile phones even more. On-screen graphics are also increasingly sharp, diverse operating systems are increasingly offering options that you can use. 
However, interesting listened to the development of mobile phones. One of the interesting to note is that the history of the first phone to use and go on sale. 
Motorola employee Martin Cooper, was the first to make cell phone calls in 1973.From the streets of New York, Cooper called the toughest rival. 
"I called Joel Engel who is a rival who worked at AT & T, who was then the largest company in the world. While we are only a small firm in Chicago. Like the flea with an elephant," said Cooper, as quoted by the BBC. 
"I said, 'Joel, this is Marty. I'm calling from the phone, for real, in my grip, a portable phone'," recalls Cooper. "There was silence at the end of the conversation. But I'm sure he growled at the time," he continued, 
Martin Cooper used the phone it is a prototype developed by Motorola, the DynaTAC.Later, the DynaTAC became the first mobile phones that are sold commercially.Launched in 1984, DynaTAC sold for U.S. $ 3,995 (around Rp35, 5 million), or if the calculated inflation, it will now be worth U.S. $ 9,000 (or about Rp81 million). 
Like what DynaTAC specs? 
The first phone sold has a height dimension 25 centimeters wide and about 10 centimeters. This does not include the rubber antenna about 10 inches long. As it weighs about 793 grams. 
Of course, when it only serves to call cell phones. Therefore there is no screen, such as mobile phones now. Its keypad is still very simple. Besides containing a number, an asterisk (*) and hash mark (#), there are also a number keypad, the RCL (Recall), Clr (Clear), SND (Send), Sto (Store), Fcn (Function), End (End ), Pwr (Power), Lock (Lock), and Vol (Volume). 
DynaTAC use a battery that can be used to talk 60 minutes duration. However, it takes 10 hours for charging or charging power. 
DynaTAC also had become a pop culture icon, due to appear in several films. You may recall one of the Wall Street scene when Gordon Geeko DynaTAC used. Patrick Bateman character in American film Pscycho also seen using this phone.
