Abstract
In Korea, M/W relay networks for broadband Internet service are being built to bridge the information gap in remote island areas. The demand for spectrum below the 10 GHz band is continuously increasing to provide long-haul(>13 km) transmission for remote islands and reliable ultra-high-definition class relay service in environments with strong rain and where topographical attenuation is a problem. Especially, because the introduction and commercialization of 5G mobile communication will rapidly increase traffic in the future, expanding the existing M/W frequency usage and redeploying the new M/W frequency for the fronthaul and backhaul networks will be needed. Therefore, in this study, M/W spectrum deployment and implementation methods suitable to the Korean spectrum policy environment are proposed by analyzing the use trend and problem of M/W relay frequencies.
