A geometric harmonic modulation (GHM) communication system communicates GHM signals
on a power line of a reconfigurable network. The GHM communication system includes
a master controller connected to the power line for transmitting GHM signals on
the power line. A boundary component is also connected to the power line. A GHM
addressable device is connected to the power line between the master controller
and the boundary component. The GHM addressable device defines a boundary of a
network region based on the GHM signals transmitted over the power line.
