The base is the primary phoneconnection with the use of a socket. Accepts the calls coming through the phone line, and then convert it into FM radio signal. After he did, is that the signal sent.

The phone displays the message from the base station and turn it into an electrical signal. The latter is then converted into sound and Eureka! A man can feel! As he speaks, the device sends voice through a second FM radio signal back to base. The latter received a change in an electrical systemsignal and then transmit the signal through the lines for the other person beyond the line. So the base and the device works with a pair of frequencies that provides speaking and listening simultaneously. This is known as a duplex frequency.

Wireless phones have his first album in 1980, but their range is limited, the sound quality is poor, because the walls and other objects as obstacles. There was little security, because the signals can be intercepted easily. In1986 award of a higher frequency of the authorities responsible for interference problems with wireless phone Reduces the amount of energy required for These Also functions is reduced. But the scope was limited and the sound quality was poor. With a further increase in the frequency of 900 MHz in 1990 to improve reception of sound is clear and long-distance has come down to a choice of channels. But the price beyond the reach of commonman.

Safety is a big problem, because the radio signals from Both the phone and receive air travel lanes open where They can be easily found by other instruments Such as cordless phones, radioscanner or baby monitor.

Related to the performance of mobile phones are radio frequency, analog to digital technology and the number of channels. Wireless phones work on different frequencies. analog technology is mainly used in wireless phones in the cheaper models. And 'more noise and less secure. The newer models use advanced digital technology. All mobile phones have rechargeable batteries.

Invasion of cell phones howeverremoved much of the attention for wireless phones, but still its market position is maintained.
