A walkie talkie (or two way radio) is a handheld transceiver that is used to communicate wirelessly over short distances.
It typically operates on two-way VHF and UHF radio frequencies and is designed for communications over a few kilometers or miles.
Walkie talkies are often used in a variety of situations, such as by police, fire, and military personnel, who use them to communicate in the field, as well as by construction workers, hikers, and other outdoor enthusiasts.
Walkie talkies are also useful for emergency situations, since they can be used to send messages even when cell phone service is not available.
