The transporter was a subspace device capable of almost instantaneously moving an object from one location to another. Transporters are able to dematerialize, transmit and reassemble an object. The act of transporting is often referred to as "beaming". Almost all Allied/Federation facilities and starships were equipped with at least one transporter device. The number of transporter devices differed; for example, most shuttlecraft had one transporter while Galaxy-class starships had twenty. When cargo bays were present, these often contained cargo transporters. The most commonly used type of transporter was the personnel transporter, designed primarily for personnel.
