There is provided an area construction method for providing a 5G mobile wireless communication network service (hereinafter, referred to as a 5G service) using a millimeter wave, in which a wireless communication area is constructed by using line-of-sight propagation of a radio wave which is emitted by using a beam-forming technology from a base station, and rough surface scattering of the radio wave by a road surface, rather than by using a diffraction phenomenon of the radio wave which causes a large loss, and by using a U-shaped UE relay or CPE.
