Two-way radios are communication devices that allow users to send and receive audio messages. They operate on specific radio frequencies and can be used over short or long distances, depending on the model. Commonly used in various settings, such as construction sites, security operations, and outdoor activities, these radios facilitate instant communication without the need for cellular networks. These devices come in different forms, including handheld units and base stations. Many two-way radios feature push-to-talk buttons, allowing users to communicate easily. They are often used by professionals, such as emergency responders and event coordinators, as well as by recreational users like hikers and campers.
