Remote relay beacon

Remote relay beacons were tall communication structures which could retransmit data through a line-of-sight network. Once deployed, the beacons would search out any nearby beacons and establish a laser connection thourgh which data could be transmitted.

Due to their line-of-sight limitations and relatively short range, they were most likely out-of-date and used only as a backup system, as they were when Dellis Tantor deployed a string of remote relay beacons to link the central computer complex and uplink tower on Ruul in 0 BBY.
