Mobile phone 40 years

Today, the phenomenon of everyday life as mobile forty years. April 3, 1973 Martin Cooper (Martin Cooper) of the Motorola made ​​the first call from a mobile phone. For context, he used the apparatus Motorola DynaTAC 8000X, and his companion was Joel Engel (Joel Engel) from Bell Labs, which was also busy developing the world's first mobile phone. Thus the call was a demonstration of Motorola victory over Bell. By today's standards, the device Motorola DymaTAC 8000x was incredibly bulky and heavy - it weighs more than a kilogram, but forty years ago it was a triumph of engineering. "Mobile phones" to be installed in cars, weighed more than ten pounds and not considered portable. worth noting that the Motorola phone with its enormous weight does not have a long battery life. Modern Android-smartphones criticized for the fact that they are not always able to provide one-time at full load. DynaTAC 8000x also could not provide it. Despite the fact that his only function was to make calls (no SMS, no Internet at that time simply did not exist), the operating time was only 30 minutes of conversation. In this case, the charging time of about 10 hours. It is worth noting that the first commercial samples Motorola DynaTAC 8000 appeared only 10 years later, in 1983, which is also not comparable to the current pace mining prototype. During these 10 years, machines have doubled the call, reducing the weight to 790 grams. Price in the U.S. is $ 3995, which adjusted for inflation is equivalent to $ 9312.
