The Ubiquitous Cell Phone
In earlier times, people would install radio telephones in their cars if they needed mobile communications badly. In this system, there would be a single central antenna tower in each city, and about 25 channels would be available. So not many people could use radio telephones, as the number of channels available were so few.With the present day cellular system, a city has been divided into small cells. So extensive frequency reuse is possible across the city, making it possible for millions of people to use their cellular phones at the same time.
This small device, tiny enough to be carried within one`s fist, has become the craze of the age. No other single electronic device has acquired as much popularity within such a short span of time. The phenomenal development in cellular phone technology and its unprecedented demand has led to a continuous supply of new cellular phones (telefone celular). The leading phone manufacturers are continuously providing new phone models to mobile crazy groups, with petite looks, cute shapes and dazzling colors, and these have been enriched with fashionable designs and multiple functionalities. For some people, carrying the latest cellular phone handset has become a fashion statement.
The other striking thing about cellular phones (telefone celular) is their easy availability. While there are costly high-end cellular phones for the rich, medium range and cheap cellular phones have also become widely available.
The array of functions the cellular phone (telefone celular) provides today is astonishing, and more and more new ones are being added all the time.
