Communications triads, so named because they involved sets of three transmitting or receiving structures, functioned as extended-range communication relays in the Unknown Regions. These triads, comprising three poles or similar structures acting as transmitters or receivers, were employed by entities like the Chiss Ascendancy, the Grysk Hegemony, and other societies located in or adjacent to the Unknown Regions.
The construction of communications triads could involve stationary land-based installations, mobile vehicles, starships, or even orbital space stations.
In the Imperial Era, a communications triad existed on the planet Batuu; the Darshi used it to maintain communication with their Grysk superiors.
