* ''{{Traveller}}'', where all interstellar messages have to be delivered by courier (although those can still jump). This has a natural impact on the way the universe works.

* In TimothyZahn's ''Literature/TheConquerorsTrilogy'', there are two possible FTL speeds for ships allowed by physics, but faster-than-light communications are impossible for humans. Humans quickly deduce, due to the coordination of the attacks, the alien Zhirrzh have a cheap, accurate method of FTL communication [[spoiler:their Elders]]. This understandably terrifies the humans. We also see a minor side-effect of this communication [[spoiler:radio waves cause Elders pain and can kill them-- which is considered an unthinkable atrocity]] caused consequences that ripple through all of the novels.

* Most of the writings of TimothyZahn fall into this category. The Literature/{{Blackcollar}} books, ''Literature/{{Spinneret}}'', ''Literature/TheCobraTrilogy'', ''Literature/TheConquerorsTrilogy'', etc. all feature settings where FTL travel is possible, even common, but FTL communications depend on actual ships making the trip.

* Creator/AlanDeanFoster uses the SubspaceOrHyperspace version in his ''Literature/HumanxCommonwealth'' series. "Space plus" is hyperspace and is used for FasterThanLightTravel - it can also be used for communication but at the same speed as starships. "Space minus" is subspace and can be used for near-instantaneous communication, but at a very high energy cost. Later in the series, it's revealed that SufficientlyAdvancedAliens figured out how to travel in space minus as well.

* Every (playable) race except the Liir (see aversions with FTL travel below) in ''SwordOfTheStars''.''VideoGame/SwordOfTheStars''.



* The Liir (dolphin-like aliens) from ''SwordOfTheStars'' use communication drones equipped with FTL engines. For gameplay reasons, there is no delay even at very long distances that require many years for the ships themselves to cross. (In game, the engines work by teleporting the object an enormous amount of times per second by small amounts, so that the ship is technically not accelerating or moving, but appears to go at up to FTL speeds.)

* Creator/AndreyLivadny's ''Literature/PhantomServer'' trilogy has a straight example ''without'' FTL travel, at least in the titular VR game. According to the {{backstory}}, an ancient race only known as the [[{{Precursors}} Founders]] discovered a way to send instantaneous messages through hyperspace, but sending physical objects proves impossible. In order to explore and settle the galaxy, they find an alternative solution. They build automated relativistic ships that travel to other stars and build space stations with biological reconstitution modules. After that, Founders then used BrainUploading to send their consciousnesses across the light years to be downloaded into cloned bodies. Meanwhile, the ships would mine resources on uninhabitable planets or asteroids and [[VonNeumannMachine make more of themselves]], increasing the speed of the exploration. The Founders have long since died out, or, at least, no one knows what happened to them. The game takes place in the Darg System and involves conflicts between several sentient species (primarily humans, Dargians, and Haash), none of whom possess instantaneous communication.

* In ''OrionsArm'' messages can be sent faster than light via [[OurWormholesAreDifferent wormhole]]. One side effect of this is that some entities use systems of wormholes to cheat the normal limitations on processing speed which makes them far more powerful than they could possibly be otherwise.

If PsychicPowers exist in a setting, they often work instantaneously at any distance, and function as a SubspaceAnsible. Quantum entanglement is a popular explanation, since QuantumMechanicsCanDoAnything.

* In ''{{Series/Eureka}}'', after Fargo and Henry build an FTL drive, the government starts planning the ''Atraeus'' mission, the first manned flight to Titan. One episode involves a scientist trying to build a SubspaceAnsible for real-time communications and telemetry with the ship. Given that this is Eureka, this ends up causing a big problem (although, not by itself).

** The existence of SubspaceAnsible also {{Handwave}}s the fact that Harbinger is capable of "[[Memes/{{Bioware}} ASSUMING DIRECT CONTROL]]" of individual {{Mooks}}, [[spoiler:despite being a Reaper whose physical form is drifting thousands of light-years ''outside the galaxy'']].

* ''Literature/WeAreLegionWeAreBob'': Everyone uses the SURGE drive, a reactionless drive that somehow uses subspace to accelerate to ridiculous speeds in realspace. In theory, it could be used for communication, though the people of Earth haven't bothered to look into it. Bill decides to stay behind in Epsilon Eridani to work on it. [[spoiler:He manages to invent an instant subspace radio with a range of twenty-five light years, but unfortunately it needs a working transponder on both ends to work. He sends off plans for the first version to the other Bobs as soon as possible, but by the end of the book only Riker's group has received the plans and built a relay]].

Space is big. No, ''[[ScifiWritersHaveNoSenseOfScale really]]'' big. You might think it's a long way to the chemist, [[Franchise/TheHitchhikersGuideToTheGalaxy but that's peanuts compared with space. Listen]]... the only way to have snappy dialogue between characters in different star systems (hell, even to '''''the moon''''') is with faster-than-light radio. This Subspace Ansible (a.k.a. FTLRadio) is also necessary for spaceships using FasterThanLightTravel to have two-way conversations, since actual radio waves ''are'' light (of a non-visible frequency) -- and are therefore slower than the ship.

Presumably, an FTLRadio is also what allows ship sensors to work faster than light, viewing objects that are light-minutes away -- or even light-years! -- in real-time. However, any attempts to explain it are indistinguishable from a HandWave (unless tachyons are involved; then it gets complicated).

* ''Literature/EndersGame'' is a major example of another writer taking the name from Le Guin. A character mentions that there is a formal name for their FTLRadio, but "somebody dredged the name ''ansible'' [[ShoutOut out of an old book]]." The working principle of an ansible link is something about "[[MinovskyPhysics subatomic philotic links]]" that form between two subatomic particles, which can be stretched infinitely when properly separated. FTL travel doesn't exist though [[spoiler:for most of the series at least]], so the ansibles are really the binding force for the entire interstellar civilization (to the point where one colony declares itself to be in rebellion and does the unthinkable by destroying their own ansible, or so it would seem...)
