A Brief on Two-Way Radio and Voice Technology

Globally utilized, the two-way radio is the most commonly used item of communication equipment. Regardless of the digital revolution replacing many older technology styles, the two-way radio is popularized due to its versatility, reliability, and functionality. It is termed two-way due to the ability to send and receive signals. Such types of radios are built for bidirectional and person-to-person voice communications. Often designed in a mobile base or stationery, the well-known example of a two-way radio is the public safety and commercial walkie-talkie.

Define Two-way Radio

A two-way radio transmits and receives signals. A broadcast radio only receives signals. While you listen to a commercial radio station on broadcast radio, two-way radios make you talk and listen to other people using the same equipment on the same frequency.

However, two-way radio has different classifications, relying on their functionality and how they are inter-connected. A conventional two-way radio operates on RF (Radio Frequency) fixed channel. Many conventional two-way radios allow a user to monitor the channel they use. On the other hand, the simplex system is used according to the system installed. Though it has limitations, the equipment is still considered the most reliable form of two-way radio.

No doubt, both radios have an effective range of one another that limits the distances they can transmit to and from. However, the open architecture makes sure simplex systems remain famous for two-way walkie-talkies and radios.

Two-way Radio Function

Every battery-powered handset has a transmitter, a loudspeaker that acts as a microphone, a push-to-talk button, and an antenna for sending and receiving radio waves- the loudspeaker and an intercom system work in a similar manner.

Make sure to share the same channel or frequency band while communicating via walkie-talkie. A device automatically broadcasts the sound of static when no one talks. And when you speak, your words are efficiently turned into radio waves. These are then sent out to other units in the accurate range.

Once a unit receives a signal, it is converted into electric currents, making the conversation flawlessly. For a full-duplex mode, more than two people may talk simultaneously on a public safety walkie-talkie or two-way radio equivalent to the way you talk on the telephone.

Advanced mobile phones depend on digital communication, and the technology improves the two-way radio system. It certainly has gained its presence. Walkie-talkies and two-way radios are practically accessible for all industries and remain the most common forms of communication.
