Patent ID: 8175088

Claim:
A system for providing mobile telecommunication services using an Internet network built with a first UTP (unshielded twisted pair) cable, which includes switching hubs each having a plurality of distributing ports, each switching hub receiving Internet signals from external Internet equipment installed in a building through the first UTP cable and distributing the received Internet signals through the plurality of distributing ports, the system comprising: a main unit including a plurality of input ports respectively connected to corresponding distributing ports of the switching hubs through second UTP cables, and a plurality of output ports corresponding to the input ports, the main unit being connected to an external mobile telecommunication base station through a first wireless link, the main unit combining a downstream Internet signal transmitted from the distributing ports of the switching hubs with a downstream mobile telecommunication signal transmitted from the mobile telecommunication base station through the first wireless link to generate a downstream combined signal, and transmitting the downstream combined signal through the plurality of output ports corresponding to the input ports; and a plurality of sub units each including an input port connected to a corresponding one of the output ports of the main unit through a third UTP cable, and an output port corresponding to the input port of each sub unit, separating the downstream combined signal transmitted from the corresponding output port of the main unit into the downstream Internet signal and the downstream mobile telecommunication signal, transmitting through the output port thereof the separated downstream Internet signal to a respective PC terminal connected to each sub unit or to a respective sub switching hub connected between each sub unit and a plurality of PC terminals, and transmitting the separated downstream mobile telecommunication signal to a respective external mobile telecommunication terminal through a respective wireless link.
