    Abstract: A powerline communication system includes a plurality of rail segments. Each of the rail segments is electrically isolated from other rail segments, and each receives power from a rail segment power supply. At least one cart operates on the rail segments. The cart has a powerline communications controller. Each rail segment has a current state defined by how many and which carts are operating on the rail segment. A central coordinator is coupled to each rail segment and configured to execute a channel estimation using a sounding protocol on its rail segment. The central coordinators store tone maps associated with the possible states of its rail segment, and possibly its adjacent rail segment. A main controller communicates with each central coordinator to direct the state and future state of its segment so that tone maps and network keys can be managed by the CCo in advance of an imminent state change. The main controller or CCo may also execute channel estimation using a sounding protocol and cause updated tone map information to be sent to each central coordinator in advance of an imminent state change.
