Abstract

A real-time management networking system for a manufacturing environment, e.g., chemical, assembly, automobile, electronic, petroleum. In a specific embodiment, the system has a spatial region, which is adapted for one or more manufacturing equipment devices. The one or more manufacturing equipment devices is associated with a manufacture of a product. In a specific embodiment, the manufacturing equipment is able to generate a high frequency noise, which causes interference with a conventional data signal, which is often unshielded. In a specific embodiment, the system has a power line gateway device provided within a desired region of the spatial region.
