Analogue Radio Systems

Analog radios have been around for almost 90 years and are the traditional form of the radio communication.

Even though digital radios are becoming increasingly popular, and there is a tendency to change from analog to digital, analog radios still have a strong presence in today´s market. Many manufacturers are still developing and improving analog two-way radios and presenting us with additional functionalities such as Lone Worker application, Alarm button, or pre-programmed text messaging.

Analog System radios transmit an analog signal over-the-air and use frequency modulation. Our original voice, which is in analog format, is modulated and amplified inside the radio before transmitted. There is no additional computer processing (i.e. digitization) inside analog radios. Analog radio systems continuously transmit radio waves that are usually modulated by a voice.

One example of analog radios are FM radio broadcasting services. Another is AM aircraft radios used to communicate between control towers and air traffic controllers. A walkie-talkie, like the Family Radio Service available, to the public, is another example of analog radio.

Advantages of analog radio system

– Equipment is less complex than digital & typically leads to less expensive equipment.
In certain conditions, able to communicate in areas where digital system have already cut-off and there is no digital signal.
– Interoperability among analog radio products from vendors (for conventional system).

Disadvantages of analog radio system

Voice quality highly depends on the environment, so a speaker near loud background noise can easily get interference.
– Less functionality and features compared to digital radios.
– Less spectrum efficiency: Only one conversation at a time on each analog channel.
