Carrier wave

A carrier wave is a wave of any type, length and dimension that can transmit anything, such as data, energy or particles.

Romulan transporters operate on a similar subspace frequency as a Starfleet transporter. With only minor adjustments, a Romulan transporter can be made to simulate a Federation transporter carrier wave. (TNG: "Data's Day")

In 2152, Lieutenant Malcolm Reed was able to locate Detention Complex 26 by isolating the carrier wave frequency of Colonel Grat's transmission to Enterprise. (ENT: "Detained")

Later that year, Reed lost his communicator while undercover on a class M planet with a pre-warp civilization. Ensign Hoshi Sato was able to locate it by picking up its carrier wave on Enterprise. (ENT: "The Communicator")

In the mid-2270s, V'Ger transmitted a simple binary code on a carrier wave signal to Earth, with the intention of reaching its creator. The message was intercepted by Commander Spock on the USS Enterprise, which was within V'Ger at the time. (Star Trek: The Motion Picture)

In 2368, Captain Jean-Luc Picard and Lieutenant Commander Data contacted the USS Enterprise-D from Romulan space by using a Romulan carrier wave so their transmission would not be detected. (TNG: "Unification II")

In 2369, the United Federation of Planets suspected the Cardassian Union was producing metagenic weapons, which could kill the enitre popluation of a planet. The weapon could be activated by a theta-band carrier wave, which would be indistinguishable from normal background noise. Captain Picard was selected for a mission to Celtris III, as he had expertise in theta-band carrier waves. (TNG: "Chain of Command, Part I", "Chain of Command, Part II")

In 2370, Geordi La Forge speculated that Lore had Data take his VISOR away because La Forge could see a carrier wave radiating from Data, which Captain Picard suggested was how Lore was controlling him. (TNG: "Descent, Part II")

Later that year, Data detected a subspace carrier wave heading for the Enterprise-D with the same signature as Bok's transporter. (TNG: "Bloodlines")

In 2371, on stardate 48543.2, Ulani Belor, a Cardassian scientist and Chief Miles O'Brien transmitted a carrier wave while onboard the USS Defiant through the Bajoran Wormhole in an attempt to cut through interference between the communication array attached to the Defiant and Deep Space 9. (DS9: "Destiny")

In 2372, Tanis tried to contact the Nacene Suspiria from the USS Voyager by using a subspace carrier wave and told Captain Kathryn Janeway that she would respond to it in 47 hours. (VOY: "Cold Fire")

Later that year, Lieutenant Tuvok authenticated a signal coming from a Federation beacon as being a Starfleet frequency, since it corresponded to a standard Federation carrier wave. (VOY: "Maneuvers")

While trying to contact a duplicate Voyager created by a subspace divergence field, Kathryn Janeway suggested to B'Elanna Torres that the two ships could recalibrate their carrier wave to match phase variants so they could communicate with each other. (VOY: "Deadlock")

In 2373, Trentin Fala attempted to contact Major Kira Nerys on Deep Space 9 by using a phase-divergent carrier wave, so no one would be able to trace her signal. (DS9: "The Darkness and the Light")

In 2374, Lieutenant junior grades Tom Paris and B'Elanna Torres transmitted a phased carrier wave to the USS Voyager after they abandoned their shuttlecraft, the Cochrane and were left floating in space in their EV suits. They created the wave by linking the communicators of both suits. (VOY: "Day of Honor")

Later that year, Voyager tried sending a message to the USS Prometheus from the Delta Quadrant through the massive Hirogen communications network. However, the message was unable to get through to the Prometheus, located at the edge of the Alpha Quadrant because Voyager's carrier wave degraded as it moved along the network. (VOY: "Message in a Bottle")

In 2376, two scientists on Kelemane's planet surmised that in order to contact the "Sky Ship", which in reality was the USS Voyager, they might need to switch to a different carrier wave. (VOY: "Blink of an Eye")

Later that year, Captain Janeway attempted to contact a missing Harry Kim by sending a carrier wave to his combadge, but by using Borg communication, so it would not be detected by the Borg cube holding three crewmembers of Voyager. (VOY: "Collective")

Later, the Delta Flyer picked up a Starfleet frequency, but it was repeating a distress call sent by Kathryn Janeway to the USS Voyager hours before. Crewman Mortimer Harren thought it was a subspace echo. Janeway disputed this, as it had .005 deviation in its carrier wave. She surmised that dark matter lifeforms were trying to communicate with the Delta Flyer by modifing Janeway's distress call to Voyager. (VOY: "Good Shepherd")

In 2377, Chakotay picked up a signal from a colony on an asteroid with a carrier wave, but there was no message attached. When Voyager arrived to the coordinates of the colony, it appeared to have been destroyed by the Borg. (VOY: "Unimatrix Zero")

In 2378, Seven of Nine performed a Fourier analysis on a garbled piece of music playing through the USS Voyager from the Doctor. While looking at the analysis in Astrometrics, Ensign Harry Kim speculated that it might be a com signal. Seven disputed that, as it did not have a carrier wave. (VOY: "Renaissance Man")
