Mobile phones are the most complex and sophisticated machines we encounter in our everyday life. To zip coded digital signals, they have to process millions of calculations per second. Nevertheless, as machine, are composed only of some components. These are:
- A microscopic microphone;
- One speaker;
- A liquid crystal display or plasma;
- A keyboard;
- An antenna;
- A battery;
- A circuit board.
The phone has a microprocessor that processes high-speed calculations, called DSP, or "Digital Signal Processor (Digital Signal Processor). This processor will make all the compression and decompression of data at a speed of 40 MIPS (million instructions per second). The microprocessor is about all the tasks of the keyboard and desk, manages the command and control signals from the base station, and coordinates the other functions.
The most amazing thing of all is that 30 years ago, it would require a multistory building to receive what now subject in the palm of the hand.
Some Problems of Mobile Phones
Mobile phones are sophisticated devices that suffer from several problems, some are:
- Internal corrosion of some components by excessive moisture or wet mobile;
- Extreme heat, in a car, for example, can damage the battery or the electronics;
- Extreme cold can cause momentary loss of the screen;
Cloning
Cloning occurs when impulses mobile phone ID are caught outside by a scanner. The identification codes thus captured can then be used for calls that are told in original mobile account.
