A walkie-talkie is a portable two-way radio that allows users to communicate wirelessly over short distances. It operates on specific radio frequencies and is commonly used in various settings, such as construction sites, outdoor activities, and events. Walkie-talkies are powered by batteries and typically feature a push-to-talk button for easy communication. These devices are popular for their simplicity and convenience, as they do not require a cellular network or internet connection. Walkie-talkies come in various models, offering different ranges and features, such as weather resistance and multiple channels. They are often used by professionals, such as security personnel and event coordinators, as well as for recreational purposes.
