1.1 Background

Mobile phone has transformed the manner in which a lot of people do business in world where having a land line was an epicurean about 10 years ago. Now it is not just a plenteous people’s style. Mobile is now a compulsion in our day to day life, buying of a mobile is a very important decision with a variety of mobile brands present in market. With latest technologies being available in mobile market via modification of the available technology. Few people prefer brands that they have been using and are very reluctant to change it, which mostly include older generation. Few customers prefer changing their brands according to the availability of different brands with latest technologies. Few of them prefer

The first cellular device and call was made in and by US people. Initially landline telephones were there everywhere and it was considered as a pride of having a telephone. Problem with it was that it was a wired system and if somebody wishes to make a call then he/she had to visit a booth or had to reach for it, that is one cannot make a call on urgent basis if stuck somewhere. Plus if there was some problem in wire then it use to take a lot of time to find and correct it. The mobile phone coalesced the landline phone system with a new technology called as wireless communication. The first landline phone was discovered in 1876. First step towards mobile phone was taken by developing a mobile radio system, it was used first in 1900’s in the form of ship to shore radio and was set up in a police car in Detroit in 1921. The commingle of this radio communication and landline phones was done after second world war. The first mobile radiophone service which allowed users to use mobile phones happened in St. Lucia in 1946. From one user in 1946 it incremented to 1 billion users in 1964 in US. Moreover, the telephones were large, energy intensive devices. It was a non-cellular system which exercised use of radio bandwidth. To develop more effective mobile phones researchers D. Ring and W. Young of Bell labs invented the idea of cellular phones, in this idea they used geographical areas separately by establishing cellular towers in different areas respectively. This allowed to decreased requirement of a lot of power by radio stations to send and receive the signal. The first set up was done in 1969 between New York City and Washington on the Amtrak Metro line. In 1973 Mr. M. Cooper of Motorola used a prototype handled cell phone to make the very first cellular
