What is the difference between a digital GSM phone and an analogue phone?
GSM stands for Global System for Mobile communication, and is a cellular radio communications system used in more than 140 countries world-wide including most European countries. GSM phones operate by means of a digital system of radio transmission. The GSM system requires that the radio signal is switched on and off very rapidly (217 times a second) to carry the messages. In analogue phones the radio signal is almost constant. Analogue phones use a similar system to your FM radio and do not generally cause a problem with interference. Analogue phones are likely to be phased out of service within five years in many countries.
