We are living in an electronic age. The whole world is taking a new turn with every fraction of time. It has given birth to globalization. The world has been contracted and concised at a tip.

There are a lot of new means of communication which have made our life so simple and easy going. Mobile phone can be seen as the most used present day phenomenon in this fast growing time. Mobile phone is a revolutionary step in the field of tele-communication.

We had the days when the telephones only served the purpose of communication through sound. Mobile phone has completely changed the concept of the telephoning. Now a phone is not only a mere phone but it is a lot in itself.

A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passanger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells.

Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted.
