The Ranger transceiver represented a specific subspace transceiver design, with its creation attributed to Sienar Fleet Systems.
Sienar Fleet Systems manufactured the Ranger transceiver specifically for deployment on the Galactic Empire's Imperial-class Star Destroyers. This device possessed a communication range extending to one hundred light-years and could simultaneously observe more than three hundred distinct subspace channels. Functionally, the Ranger systematically scanned the subspace environment, shifting its operating frequency every tenth of a second. Messages picked up by this transceiver could then be deciphered via an integrated encryption computer linked to the vessel's com-scan architecture.
