Remote relay beacon. Dellis Tantor plants a 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.
  A relay takes a high current circuit and uses low current to turn  the high current on and off. Its basically a high current switch.  There are coils that are designed to handle the high currents  constantly. A switch could do the job of turning circuits on and  off but has a drastic higher failure rate.  The reason for using a relay, is so that you can power a load that  requires a lot of current, without having to run heavy cable all  the way to the switch and back. Also, for safety, so you don't have  to throw the switch on a potentially lethal amount of current.
