Transmission is FTL travel achieved through a difficult and dangerous method of manipulating an object's local Signal. It requires a highly adept practitioner, and is usually not performed aboard the ship itself; while such an act is possible, anything more than a tiny crew will generate too much Noise to make any kind of FTL jump. The practitioner more commonly pushes (or "kicks") the ship to its new destination. The transit is almost instantaneous, even across huge distances, but space's resistance to the kick increases geometrically across larger distances.
Transmission is influenced in part by one of the skills of the Talents in Anne McCaffrey novels.
