1. A module for coupling a wired digital data signal to a wireless data unit, for use with an existing electrical AC power distribution infrastructure in a building, the infrastructure having an AC power wire pair carrying an AC power signal and a wall-mounted AC power outlet connected to the AC power wire pair, the AC power wire pair concurrently carrying a 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 module comprising:

  • a power connector that is electrically and mechanically connectable to the AC power outlet for connecting to the AC power wire pair;

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

    a powerline modem coupled to the high pass filter and operative for bi-directional packet-based digital data communication of the wired digital data signal over the AC power wire pair using a wired digital data protocol;

    a radio frequency modem operative for conducting standard-based bi-directional packet-based digital data communication of a wireless digital data signal using a wireless digital data protocol;

    a packet-based digital protocol adapter consisting of one of a bridge, a router and a gateway, coupled between said powerline modem and said radio-frequency modem for converting data between the wireless digital data protocol and the wired digital data protocol; and

    a single enclosure containing said power connector, said high pass filter, said powerline modem, said radio frequency modem and said protocol adapter.
