Communication radios are radios that can transmit and receive radio signals, unlike an ordinary broadcast receiver that only receives audio data. It is a radio, an antenna and a transceiver in a single unit, often used for direct bidirectional communication with other wireless users with similar devices. It can also be used as a computer radio, or as part of a larger device that receives and transmits on its own. It has become very popular in all walks of life for various purposes. As an example, business mobiles and walkie talkies have small communications sets that are activated by the user pressing certain buttons.

The technology behind this type of radio is based on the operation of microwaves. Microwave is a form of electromagnetic radiation that is commonly understood to be sound waves or extremely fast vibrations of matter. In the case of radio waves it is waves that are slightly longer than the wavelength of the sun. The emitted radio waves are in the form of radio frequency.

Microwaves can either be transmitted or received, depending on their characteristics. In this case, two-way radio communications means being able to send and receive waves. There is a difference between the electrical and electromagnetic fields produced by radio waves. Electromagnetic waves are shorter and do not create any sort of signal interference. On the other hand, electrical waves travel long distances and may cause communication problems.

Communication radios can be used to transmit audio information, either as voice data or as telephone conversation. This kind of technology has come a long way in terms of its use. Commercial devices come with various features to make them suitable for different needs. If you want to talk on your walkie talkie or use your MP3 player while jogging then there is no other choice but to get a communication device with a short antenna, so that you are able to receive signals from a long way away.

There are two-way radio communications systems that use different frequencies. These are called analog and digital radios, which are also sometimes used interchangeably. If you are looking for a communication device with longer range then you will want to get a digital one. Digital radios generally cover longer ranges even in comparison with analog ones.

Communication radios are designed to work in places where mobile phones do not reach yet. You can get one that covers a wider frequency band that is covered by mobile phone networks. As a matter of fact, many countries use this type of technology for their mobility needs.
