It was a Soviet scientist that developed first mobile phone, first satellite was launched by USSR, first man and woman in space were sent by USSR. How could you say that USSR was merely copying everything?
You must be a communist. Martin Cooper (born December 26, 1928, Chicago, Illinois, U.S.) American engineer who led the team that in 1972-73 built the first mobile cell phone and made the first cell phone call. He is widely regarded as the father of the cellular phone.
@@Rmat7552 In 1953, Kupriyanovich graduated from Bauman Moscow State Technical University. In 1955, Leonid Kupriyanovich published the description of a simple walkie-talkie amateur radio station for personal use in the Soviet amateur radio magazine "Radio," 1955, N2. It operated on two vacuum tubes. The walkie-talkie weighed about 1.2 kg and had 1.5 km operating distance. In 1957 Leonid Kupriyanovich presented a micro walkie-talkie radio version the size of a matchbox, 50g in weight and had 2 km operating distance. Also in 1957 he made an experimental model of a wearable automatic radio landline extender ("radiophone"), called LK-1 (not to be confused with the cancelled Soviet spacecraft of the same name or LK-1 (ЛК-1) the first Soviet trolleybus). His device consisted of a stationary module and a portable handset. LK-1 was reportedly 3 kg in weight, 20-30 km operating distance, and 20-30 hours of battery life. Leonid Kupriyanovich patented this landline extender in 1957 (author's certificate № 115494, 1.11.1957). The stationary module, following the author's description, could serve several customers. In 1958, Kupriyanovich purportedly made the new experimental "pocket" model radio phone. This phone supposedly had 0.5 kg weight. Kupriyanovich proposed the device to serve more customers and named it a correllator.[1][2][3][4] In 1961, Leonid Kupriyanovich presented a pocket automatic radio phone that could fit in the palm of a hand. This pocket mobile phone weighed only 70 g and had an 80 km operating distance. Kupriyanovich told correspondents of the АПН news agency that in the USSR, the production of this device was planned. He also reported the plans for the construction of ten base stations in Moscow to create a mobile communication network. The first station in Moscow was supposedly planned to be constructed in Mazilovo.[5][6] In the 1960s Leonid Kupriyanovich's electronic set "Rhytmoson" was manufactured in the USSR and purchased for medical purposes.
Death note എവിടെ?? , അത് ചെയ്യാത്തത് എന്ത്കൊണ്ടാണ് സർ?? ആ കഥ ഇഷ്ടപ്പെട്ടതുകൊണ്ടല്ലേ നിരന്തരം ചോദിച്ചുകൊണ്ടിരിക്കുന്നത്... വളരെ വ്യത്യസ്തമായ കഥയായിരുന്നു.
