It operates on specific radio frequencies, enabling instant communication over short to medium distances. Commonly used in various fields, such as emergency services, construction, and event management, two-way radios are essential for coordinating activities and ensuring safety. These devices come in various forms, including handheld units and mobile radios installed in vehicles. Users typically communicate by pressing a button to talk and releasing it to listen, making it easy to share information quickly.
