The amazing technology cell phones have these days is surprisingly growing and developing.
Cell phones started out as an idea for a mobile phone that can be used from a car, within a given range. This was happening back in 1947. Since then, their purpose was achieved and greatly exceeded.
The mane comes from the word cellular combined with the normally used word, phone. Cellular because their whole technology is based on cells of signal. Each cell has as a centre a transmitter that assures the mobility and the great range, almost worldwide, of mobile phones. These transmitters are placed in such a way so that they can form a network with absolutely no uncovered spaces. Not all portions have been covered, but the civilized and populated locations all have mobile phone operators and coverage.
