"Noise" as in some random variations in the station environment:

Different factions would have different "nodes" around which elements would be randomly organized; all Xang Xi stations would look similar, but each station would look somewhat different from the others.

Elements that could be randomized may be colored panels along the walls, lighting, the ships that are present (although I'd prefer for that to be according to what's in local inventory), various light colors especially along the struts holding the ships; perhaps each faction would have a specific docking bay door.

It would also be nice to see out of the station via a window into the local space environment.
