События
Leonid Ivanovich Kupriyanovich born in Moscow, Russia. (7/14/1929)
Leonid Ivanovich Kupriyanovich creates the first experimental "mobile phone" with a 20-30 km reach and 20-30 hour battery. The focus is usually on the U.S. but this marks the start of the USSR's mobile phone, one that came before the prototypes in the U.S. (1957)
Leonid Ivanovich Kupriyanovich introduces the "Altai" mobile phone to the Soviet Union, 10 years before Martin Cooper's first mobile phone. While not as well known, it's impressive that the USSR had mobile phones before the U.S. (1961)
