Mobile Two-Way Radios are vehicle-mounted wireless devices that are used to send voice or data messages one-to-one or one-to-many over radio frequencies within a local area, city, or state. They are often installed on the dash of a vehicle, and can run off its power source. They are used by someone who doesn't need to communicate away from their vehicle.
