Interdimensional tachyon bridges built into jumpgates and jump-capable ships can provide a persistent tachyon relay between normal and hyperspace without an open jumppoint, and transmit data through hyperspace as tachyon beams to other jumpgates in a manner similar to the hyperspace beacon network. This enables real-time interstellar communication between any ship or facility in normal space within range of a jumpgate, and any ship in hyperspace that is "on the beacon." Transmitter power and receiver sensitivity affect availability and quality of service as with many communication systems.
