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. |

1. A real-time management networking system for a manufacturing environment, the system comprising:
a spatial region, the spatial region being adapted for one or more manufacturing equipment devices, the one or more manufacturing equipment devices being associated with a manufacture of a product, the manufacturing equipment being able to generate a high frequency noise, the high frequency noise being able to cause interference with a data signal; a power line gateway device being provided within a desired region of the spatial region, the power line gateway device positioned between the external data source and a plurality of power line client devices, the power line gateway device comprising a power line device coupled to an interface device and a coupling device configured to couple the power line gateway device to a plurality of power line client devices, the interface device being coupled to a data connection, the power line device being capable of converting a data signal from the data connection into a power line signal; one or more shielded cables coupled to the coupling device, the one or more shielded cables comprising a first end and a second end, the first end being coupled to the coupling device, the one more shielded cables comprising a conventional cable having a first insulating material provided on the conventional cable, a shielding provided overlying the first insulating material, and a second insulating material overlying the shielding, the one or more shielded cables being adapted to transfer the power line signal free from any substantial interference with the high frequency noise being able to cause interference with the power line signal; and an outlet device comprising customer-premises equipment (CPE) device, the CPE device being capable of controlling the plurality of power line client devices, the outlet device coupled to at least the second end of the one or more shielded cables, the outlet device being adapted to convert, at the CPE device, the power line signal received from the powerline gateway device via the one or more shielded cables into at least an Ethernet signal or a RS232 signal, the Ethernet signal or RS232 signal being substantially free from interference from the high frequency noise. |
