<p>Disclosed is a system for providing services of wireless communications such as the mobile communication and the wireless internet. The wireless communication service system according to the present invention comprises: a wireless communication service apparatus for outputting signals received from an external network via a plurality of output ports; a signal coupling unit for coupling each output signal of the output ports in the wireless communication service apparatus to make each output signal have a phase difference between each other; and an electricity supplying line having one end connected to the output port of the signal coupling unit and the other end connected to an antenna. The present invention couples a plurality of signals outputted from the output ports of the wireless communication service apparatus and transmits the coupled signals to make the signals the phase differences or time differences from each other, thereby enhancing transmission capacity and speed, and if the coupled signals are transmitted, makes a user terminal process signals in the same manner with receiving a plurality of signals transmitted via different fading paths, thereby may obtain the same effect with an MIMO type wireless communication service system. Additionally, the present invention may transmit the signals, coupled to have the phase differences or the time differences, to the antenna via one electricity supplying line, thereby not needing additional installation of the electricity supplying line for constructing the MIMO system and, accordingly, drastically enhancing the transmission capacity and the speed of the wireless communication at minimal costs.</p> |
