Two-way radio
A two-way radio is a radio that can both transmit and receive, unlike a broadcast receiver which only receives content. A two-way radio allows the operator to have a conversation with other similar radios operating on the same radio frequency . Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies, handie-talkies, or just hand-helds.The above text is a snippet from Wikipedia: Two-way radio
