When were mobile phones first invented?
According to historical records, the first mobile phone was
invented by Ericsson in Sweden in the year 1956. The device came to
be known as the Mobile Telephone System. The phonewas easy to use
since it was automatic but its biggest downside was that it weighed
about 40 kilograms. Later in 1965, an upgraded version was launched
by the company in order to convince the consumers which became very
successful between 1965 to1983 since many bought it as it was only
9 kilograms. Leonid Kupriyanovich, a radio engineer in Moscow,
Russia developed an automatic mobile phone known as LK-1 in 1957. A
year after, Russia also developed and introduced Altay service,
which could be used by mobile phone users while driving. Russians
continued to use the service until 1970.
