1. A device for non-wired coupling of a wired digital data signal to a non-wired data unit, for use with an existing electrical AC power distribution infrastructure, the infrastructure having a power wire pair carrying an AC power signal, said power wire pair concurrently carrying a bi-directional wired digital data signal and an AC power signal using frequency division multiplexing, wherein the wired digital data signal is carried over a high frequency band and the AC power signal is carried over a low frequency band, said device comprising:

  • a power connector connectable to the power wire pair;

    a power supply coupled to said power connector for powering said device;

    a high pass filter coupled to said power connector for passing only the wired digital data signal;

    a power wiring modem coupled to the high pass filter for coupling to the bi-directional wired digital data signal;

    a non-wired modem for bi-directional transport of a non-wired digital data signal and for coupling the non-wired digital data signal to the non-wired data unit;

    a multiport device consisting of one of a bridge, a router and a gateway coupled to said power wiring modem and said non-wired modem for converting the non-wired digital data signal and the wired digital data signal and vice versa; and

    a single enclosure containing said power connector, said power supply, said high pass filter, said power wiring modem, said non-wired modem and said multiport device, wherein said enclosure is mechanically attachable to the existing electrical AC power distribution infrastructure.
