     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]    Referring to the drawings, and initially to FIG. 1, a wire transmitting facility in accordance with the present invention is illustrated and comprises a transmitting device  1  and a network access device  6 , such as a wireless local area network (WLAN) access device  6  to be coupled together or to be coupled with each other. The WLAN access device  6  may be used for coupling to the internet or the other network systems.  
         [0017]    The transmitting device  1  includes an electric power supplier, such as an alternate current (AC) electric power supplier  2 , and an electric wire transmitting integrated circuit  3  coupled to an AC electric power source  5 . The AC electric power supplier  2  may convert the AC electric power from the electric power source  5  to a direct current (DC) or a required or treated or converted electric power.  
         [0018]    For example, the electric power supplier  2  may provide the DC electric power, such as the 5V DC electric power to a socket or a plug or a coupler or a terminal  61 , such as an RJ-45 terminal of the WLAN access device  6 , via a cable or an electric wire  21 .  
         [0019]    The electric power supplier  2  may further provide the DC electric power, such as the 5V DC electric power to the electric wire transmitting integrated circuit  3  via another cable or electric wire  23 , such that both the electric wire transmitting integrated circuit  3  and the WLAN access device  6  may be energized by the same electric power supplier  2 .  
         [0020]    The transmitting device  1  includes a socket or a plug or a coupler or a terminal  4  coupled to the electric wire transmitting integrated circuit  3  and also coupled to another socket or plug or coupler or terminal  62  of the WLAN access device  6 , with such as a cable or an electric wire  41 .  
         [0021]    It is to be noted that both the electric wire transmitting integrated circuit  3  and the WLAN access device  6  may be energized by the same electric power supplier  2 , such that the wire coupling for the wire transmitting facility in accordance with the present invention may be greatly simplified, and the manufacturing cost for the wire transmitting facility may be decreased.  
         [0022]    Referring next to FIG. 2, the electric wire transmitting integrated circuit  3  includes a coupler  31  coupled to the electric power source  5  via an electric cable or wire or line  51 , for receiving both the electric power and information signals or messages from the electric line  51 , and for sending treated information signals or messages to the electric line  51  or another electric line  52 .  
         [0023]    An analog signal driving device  32  is coupled to the coupler  31 , for amplifying the signals from the coupler  31 , and for facilitating the signal sending or receiving or transmitting in the electric wire transmitting integrated circuit  3 .  
         [0024]    A converter  33  is coupled to the driving device  32  for converting the signals from the driving device  32  to the other signals. For example, the converter  33  may be used to convert the analog signals from the driving device  32  to the digital signals; or, on the contrary, may be used to convert the digital signals from the driving device  32  to the analog signals  
         [0025]    An electric wire access control device  34  is coupled to the converter  33 , and includes a medium access control layer (MAC) for fetching or storing or treating or processing the signals from the converter  33 . The electric wire access control device  34  further includes a physical layer for signal encoding or regulating purposes, such as for othogonal frequency division multiplexer (OFDM) purposes.  
         [0026]    Another control device  35 , such as a wireless transfer protocol control device  35  is coupled to the electric wire access control device  34  for providing information signals or messages that conformed to the institute of electrical and electronic engineers (IEEE) 802.3, and for communicating with the ethernet.  
         [0027]    The wireless transfer protocol control device  35  is also coupled to the terminal  4  for coupling the electric wire access control device  34  to the terminal  4 , which is then coupled to the terminal  62  of the WLAN access device  6 , for allowing information signals or messages to be coupled or communicated between the WLAN access device  6  and the electric wire transmitting integrated circuit  3 .  
         [0028]    In operation, as shown in FIG. 3, two or more transmitting devices  1  may each be coupled to a WLAN access device  6  with electric wires  21 ,  41 , and may each be coupled to the AC electric power source  5  of the family housing or building  70  with plugs or couplers  50  that may be coupled to the plugs or sockets or couplers  71  of the family housing or building  70 .  
         [0029]    As shown in dotted lines in FIG. 3, the plugs or sockets or couplers  71  of the family housing or building  70  may be coupled together with one or more inbuilt electric wires  7 . The information signals or messages from or between the WLAN access devices  6  may thus be coupled or communicated with the electric wire transmitting integrated circuit  3  and the electric wires  7 .  
         [0030]    Once again, the electric power supplier  2  may provide the DC electric power, such as the 5V DC electric power to both the electric wire transmitting integrated circuit  3  and the WLAN access device  6 , via the cables or electric wires  21 ,  23 , for allowing both the electric wire transmitting integrated circuit  3  and the WLAN access device  6  to be energized to the same electric power supplier  2 .  
         [0031]    Accordingly, the wire transmitting facility in accordance with the present invention may be provided for coupling a WLAN access device to network systems with a single electric power source, and for simplifying the electric wire coupling of the WLAN access device, and for decreasing the manufacturing cost for the wire transmitting facility, and/or for allowing two or more WLAN access devices to be coupled and communicated with each other with electric wires of family housings.  
         [0032]    Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
