The ECHOnet is used by many of the inhabitants on Pandora, and a transmitter/receiver is even built into each of the local CL4P-TP units. The ECHOnet was under the maintenance of a small group of individuals, although vital satellite uplinks for it are in one of the Crimson Lance's installations. Exposition of the ECHOnet is given when the Get Some Answers mission is accepted. At this point Commandant Steele orders the complete shutdown of the ECHOnet, which cuts off Helena Pierce in mid-transmission and blocks the Guardian Angel's ability to see events unfold.
