A communicator is a personal handheld communications device which allowed for a person to communicate with another person over great distances - such as person to person, or person to ship or other installation. Communicators used subspace radio to transmit messages.

Starfleet used communicators as communications devices when a person was away from the ship, or in situations on board a ship or installation where the comm system was not usable or there was a need to avoid using the comm. (TOS episode: "Mirror, Mirror")

Communicators were in use by the Earth Starfleet in the mid-22nd century, and used a flip top model whose basic design would remain unchanged for over a century. (ENT episode: "Broken Bow") In the 2270s and 2280s Starfleet experimented with using a communicator which was worn on a person's wrist. As well as a perscan device (inside the 2270s uniform belt) that monitors and saves its wearer's current lifesigns. However, Starfleet discontinued that and the wrist communicator when it was found the devices were prone to failure after even a minor impact, and returned to a flip-top design. (TOS reference: Mr. Scott's Guide to the Enterprise, TOS novel: Ex Machina)

By the 2340s, communications technology had advanced to the point that Starfleet was able to build a communication device into the uniform insignia pin. This device, called a combadge quickly replaced communicators as a means of communication between members of Starfleet. (TNG episode: "Yesterday's Enterprise") Benjamin Sisko was so used to the combadge that when he traveled back to the 23rd century USS Enterprise, he tapped the uniform insignia on his shirt out of habit before remembering the need to use his communicator instead. (DS9 episode: "Trials and Tribble-ations")

Communicators were still used occasionally when a higher power level was needed to break through a jamming field, and the USS Enterprise-D carried a number of these communicators. (TNG novel: Foreign Foes)


The TOS version was referenced, along with the "Beam me up" fanfare on an episode of "Captain Power and the Soldiers of the Future" (1987)". The series debuted during season one of TNG.

In the Dark Mirror version of the Terran Empire, communicators were not used by individual personnel, as that would make them too easy to locate and (presumably) kill; all communications were handled by the ship's computer.

The novel Q-in-Law, set in 2366, reveals that Q's combadge actually functions as any standard-issue Starfleet communicator. When hailed by Captain Picard as "Mr. Q," to report to command staff for a meeting-even the omnipotent, omniscient Q is taken off guard.

For the 25th century envisioned in Imzadi, Starfleet surgically implanted communicators into its members.

From Wookieepedia, the Star Wars wiki.

A Hush-98 comlink.

A comlink was a portable device that transferred voice signals from one location to another.



Comlinks came in numerous varieties, though most had the same central systems: a receiver, a transmitter, and a power source. Comlinks were typically small, palm-sized devices for easy transportation and concealment. They often weighed as little as 0.1 kgs. More advanced models featured encryption routines, frequency search controls, sound reproduction matrices, silence projectors, and built-in ports for data transmission. Some comlinks, such as those used by the Jedi, were equipped with complex security devices that prevented unauthorized use. Comlinks were often integrated into helmets, such as those that clone troopers and later stormtroopers wore.

Harsh environments required to possess a reliable comlink with long range.

Without satellite amplification, a standard comlink had a range of about 50 kilometers. This range was decreased drastically in dense urban zones due to the presence of high levels of electromagnetic interference, though this could be circumvented by the use of wired transmission networks. Range and signal strength against interference was primarily dependent upon the power source; correspondingly, comlinks with higher levels of available energy (such as military and vehicle-mounted models) had much longer ranges and less interruption than hand-held civilian models. Between 32 BBY to 8 ABY, comlinks with standard security enhancements cost 200 credits.

Comlinks were also used aboard starships, mainly for short-range communications such as landing/departure clearances and formation commands. For longer-range communications, many starships utilized subspace radios, which necessitated an even larger power supply.[1]

Certain comlinks also had the ability to track other comlinks, presumably by following a transmission feed between them.

From Traveller Wiki - Science-Fiction Adventure in the Far future

A communicator is defined as a radio transmitter/receiver combination capable of operating off an internal power source; it is portable in the sense that it need not be connected to a power supply. It may transmit and receive both voice and data. Communicators 0.2 liters and under can be worn as earpieces, which are unnoticeable to the casual observer.



A miniaturized electronic device capable of receiving voice or radio input, recording it, and transmitting this information either on a given external signal or continuously. Reception and transmission is on the standard voice communication bands. Thus, the device can listen for signals and then retransmit them, or it can continuously transmit a prerecorded message. Tape length is 10 minutes; transmitter range is line of sight (it is blocked by buildings, mountains, and so on)

Laser Communicator

The laser communicator is a Iine-of- sight device with a regional range (500 km). This distance is seldom needed on a world’s surface since the distance to the horizon limits the range first, but this range often allows contact with an orbiting ship.

The laser communicator’s main advantage is that it provides a tight beam and therefore a private means of communication. Sets of laser-communicators are often set up in a “repeater” network. Spaced at a horizon-to-horizon distance, the units can instantly convey a message around a world by retransmitting it from station to station.

Video Communicator

The video communicator transmits a voice and two-dimensional image over a range of 500 km (regional). The unit is small enough to be carried in a pocket or hung on a belt. The communicator has a built-in microphone and video camera for input and a small speaker and a polylucent cuprothallium display for output. The cuprothallium display slides into the main housing when not in use, and the video camera can be switched off if desired. Commdots can be used to speak and listen if the device is attached to a belt. By opening the unit up, interior controls can preselect five different frequencies for current use; one of these can then be chosen using the frequency selection knob on the front of the communicator. The communicator can transmit and receive simultaneously. When used with commdots, the communicator can be used to set the commdot frequencies to itself; it will also automatically multiplex with a commdot for any of its five active frequencies.
