Subspace communication was the most common form of communication used in the Federation. Because the system transmitted messages and data through subspace, it allowed the information to travel faster than the speed of light.
Subspace communication could be jammed on a large scale via the use of the subspace equaliscopic system. (Star Trek: False Vacuum: "Structural Unemployment")
