Modern life is filled with various technological devices. Every day, people check emails from their tablets and laptops, communicate on social networks, call their friends and family from anywhere in the world. Although only sixty years ago, the latter could only be dreamed of. After all, what functions the current smartphone performs, previously could only be afforded by a computer the size of a small cabinet.
The first cell phone
The first official cell phone was the device of the American engineer Martin Cooper, director of the mobile communications department of Motorola. On this machine, on April 3, 1973, he first called his competitor from Bell Laboratories, Joe Engel.
The phone with a protruding antenna weighed a little over one kilogram and worked in the talk mode for no more than an hour. The cellular device did not have any additional functions, as well as the display familiar to a modern person, only twelve keys (10 digital keys, call and end a call).
According to the official version, the first commercial cell phone, DynaTac, was released on June 13, 1983 by Motorola.
However, there is every reason to claim that the first cell phone was produced in the Soviet Union. It was the domestic radio engineer Leonid Kupriyanovich who created a sample of the LK-1 mobile phone, which was tested in 1957. The first "mobile phone" had a range of up to thirty kilometers, but its main disadvantage was the unacceptable weight for such a phone - three kilograms.
Therefore, a year later, Leonid Ivanovich improved the cell phone model. The updated apparatus was the size of a pack of cigarettes and weighed only half a kilo. The telephone made it possible not only to make outgoing calls, but also to receive incoming calls from stationary devices and street machines.
