How the Mobile Phone Works: Detailed description of the physics behind the functioning of a mobile phone.

Introduction: The following report will give the reader information about mobile phones. It will inform the reader about how a mobile phone works, the history and development of mobile phones, the impact on health and society, and the future predictions about mobile phones.

History and Development:A mobile phone is a radio- a really sophisticated radio- but a radio nonetheless.

The basis of a mobile phone had started off by a radio. This is because a phone uses a set line to send and receive a message or a call. But by using the concept of radios, the average radio has made the typical telephone into a cellular phone. The radio used to be, and still is, used as communication device in taxis and police cars, where one vehicle could communicate with another with no set line. With this concept, the mobile phone was developed.

The first fully automatic mobile system was made by Ericsson called the MTA and was first commercially sold in Sweden in 1956.

With the creation of the mobile phone, there was a whole new world to develop and update on. Since the invention of the mobile phone, there have been a vast amount of developments and additions made to the mobile phone. The old mobile used to have a battery life of about three hours, but now the new generation phones can run for three days continually.

The old generation phones could only make and receive calls but these days phones can send messages, take photos, find the nearest restaurant, receive the latest stock market results, read the latest movie reviews, internet connection, listen to music, watch a video clip and a substantial amount of other things as well.
