Who invented the mobile phone?

Very few people know that the first mobile phone was invented in the USSR in 1957.

It weighed about 3 kg and was invented by Leonid Kupriyanovich. He later kept on working on his invention. As a result, in 1961 the weight of the mobile phone changed and it weighed 70 grams.

In 1957 Kupriyanovich got a patent for his invention. The drawback of his invention was that very few phones could be connected to one base station.
