Patent ID: 8693498

Claim:
A wireless fidelity (WiFi) apparatus for wireless Internet, the WiFi apparatus comprising: a signal inputting unit comprising a plurality of input ports for inputting a plurality of mobile communication signals, respectively, and an input port for inputting an Ethernet signal; a signal converting unit for converting the inputted Ethernet signal into a plurality of WiFi signals; a signal coupling unit for coupling the plurality of inputted mobile communication signals to the plurality of WiFi signals converted by the signal converting unit, respectively; a signal outputting unit for outputting a plurality of coupled signals coupled by the signal coupling unit through a plurality of output ports, respectively; and a coupler configured to: split each of the coupled signals outputted from the signal outputting unit into at least two signals having a predetermined phase difference from each other; and output a first split signal that is split from a first coupled signal outputted from the signal outputting unit together with a second split signal that is split from a second coupled signal outputted from the signal outputting unit such that the first and second split signals have the same predetermined phase difference to each other through a same one port, wherein the first and second split signals are subsequently transmitted to a same service area from a same antenna.
