Sometimes referred to as Walkie-Talkies, especially in the US, two-way radios are designed to be compact hand held devices with the ability to change channels (frequency) operating on a short range.

Looking back, they were originally developed for the Canadian government during World War 2. They then became commonplace in armed forces around the world and then spread into commercial industries such as construction and health and safety.

A two-way radio is built on a half-duplex channel, which means that only one radio can transmit at a time. The ability to transmit voice is achieved via a button or push to talk (PTT) switch that engages transmission. Two-way radios can be used in conjunction with a range of accessories, such as earpieces and microphones, but more commonly used as standalone devices using an inbuilt speaker and microphone.

Two-way radio\’s are able to transmit and receive to and form other two-way radios and also with vehicle mounted devices and radio base stations (office based desktop devices).

Radio Communication has become a vital part of commercial life and is often used at sporting and musical events, on construction sites, within the film industry and on theme parks. It is not uncommon for two-way radios to be used for marine or aviation communications, especially in smaller boats and aircraft.

As with most modern day technology, two-way radios have a rang of accessories available, which may vary by manufacturer. You can get replacement batteries, rechargers, earpieces or headsets and mics for most two way radio devices.

As technology advances, so do two-way radios. What were once seen as a very basic device now offers convenience and durability making them ideal for virtually any environment.
