Dellis Tantor plants a remote relay beacon. Remote relay beacons constituted towering structures for communication, designed to relay data across a network via direct line-of-sight transmission. Following their activation, these beacons would scan the surrounding area for other beacons, creating a laser-based connection to facilitate data transfer.
Given their restricted range and dependence on a clear line of sight, it's probable that these beacons had become obsolete, functioning mainly as a redundant system. This was the case when Dellis Tantor set up a series of these beacons to connect the central computer complex with the uplink tower located on Ruul during 0 BBY.
