1____The invention of a mobile phone, or a cell phone as it’s alternately called, is credited to Dr Martin Cooper at Motorola. He made the first successful call over the system on April 3, 1973. 2.___ A mobile phone allows you to use telephone service from almost anywhere. A portable or cordless phone allows you to talk wirelessly but the receiver is still connected to the same land line. A mobile phone allows you more range and allows you to communicate much further from virtually anywhere in the city, country, or world. You have the ability to make a telephone call or receive one wherever you happen to be with your mobile phone.3___Mobile phones come in many different configurations. Most are about the size of a candy bar, have a display and a keypad. Some configurations come with a flip that opens up to show the display and the keypad, thereby keeping it protected. Cell phones are available big and small, simple and complex. Some just make simple phone calls; others have tiny cameras, MP3 players, digital organizers built into them. Some of the newer models can even allow you to use the Internet over them, browse various services such as news, or movie listings. New models are always being introduced. New fashions, new technology, more features, cheaper cost, better performance keep the market place filled with plenty of choices. 4.___ The mobile phone has radically changed the world since its introduction in 1973. With each year more and more people own one. Most families typically have two or three. The ability to easily communicate to anyone, anywhere, is a powerful concept. This was true when the telegraph was first invented, and then taken to a new level with the advent of the telephone. The mobile phone is just the next extension of that technology. 5.___ Since the mobile phone is a combination of a telephone and a radio, these two devices are the building blocks upon which the mobile phone was developed. In addition, tiny computers (microprocessors) are needed to control the radio and its connection to the nearest base station. The telephone was invented by Alexander Graham Bell in 1876. The radio was invented by Guglielmo Marconi in 1896. The microprocessor was invented by Gary Boone in 1971.
