First cell phone
first official cell phone was the apparatus of American engineer Martin Cooper, Director of Mobile Communications at Motorola. On this apparatus, on April 3, 1973, he first called his competitor from Bell Laboratories Corporation – Joe Engel. The
phone with an antenna sticking out weighed just over one kilogram and worked in conversation mode for no more than an hour. No additional functions the cell device had, as well as the familiar display for modern humans, only twelve keys (10 digital, call and end 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 state that the first cell phone was produced in the Soviet Union. It was the domestic radio engineer Leonid Kupriyanovich who created the sample mobile phone “LK-1″, which was tested in 1957. The first “mobile” had a range of up to thirty kilometers, but its main minus was unacceptable for such phone weight — three kilograms.
Therefore, a year later Leonid Ivanovich improved the model of the cell phone. The updated apparatus was the size of a pack of papyros and weighed just half a kilo. The phone allowed not just to make outgoing calls, but also to receive incoming calls from landlines and street machines.
