How Do 2 Way Radios Work?

A two-way radio communication is a communications system that allows two-way exchange of data, i.e. transmission. A two-way radio can receive and transmit radio waves, unlike a purely broadcast receiver that only receives information. It is also a data transceiver, a sender and receiver in a single unit, commonly used for bidirectional human-to-human voice communication for personal conversation. In some units, it is used as a personal alarm clock.

The two way radio communications systems usually use the analog signal technology for transmission and reception. These days however, most 2-way radios to communicate using digital data, which provides greater efficiency, reduced cost, more channels and less power consumption. They are becoming more popular because they allow greater flexibility and portability, as well as a wider range of services. Digital data transmission is more reliable and less susceptible to interference than analog signals.

Most modern digital 2-way radios have built-in GPS or WAAS (Wide Area Augmentation System) capabilities. Some older radios, however, do not have this option. Some older two-ways also have the option to scan other wireless devices. If you are searching for a two-way communications device, you should be aware of the various types of options available for the types of purposes you intend to use them for.

The push-to-talk 2-Way Radio is a very simple and basic form of communication that requires no installation. The push-to-talk feature simply calls the number on the line using a microphone or voice prompt. If the call is successful, then the person answering the call will press the send button on their radio, and the call will be transferred to the appropriate station. If the call is unsuccessful, the person answering the phone will simply press the return key on their radio.

Selective Calling, also known as Automatic Identification Reporting System (AIDS), is a system that allows multiple users to enter a single frequency channel and select which channel they would like to talk on. When multiple people call from the same location with the AID enabled device, it will record the number and the caller’s name. This information can then be accessed by whoever calls in order to listen in on the conversation and determine who is talking. The system will then assign channels frequency channels to each person, based on how many people have called in at that time. Channel numbers can be stored in a database so that conversations can be organized and sent to specific groups.

Automatic Identification Reporting System (AIS) is another type of communication device used in mobile communication systems. Unlike with push-to-talk 2-way radios, automatic communicating systems must be manually activated before being used. Instead of automatically transmitting a channel number to which people can reply, AIS broadcasts channel names to which people must respond or else there will be an overflow of messages.
