In this study, we studied the application usefulness of a wired drone system capable of obtaining power and data and communication relay in order to prepare for release of control rights due to power cut off or damage to repeaters in disaster areas due to disasters or because there are no relays in mountainous areas or at an altitude of 150m or higher. In order to temporarily connect the repeater developed using the 800MHz band of LG U+ domestic telecommunications company to nearby available base stations and restore the communication network, it is mounted on a wired drone system that can take off at an altitude of 20m and fly for more than an hour to strengthen canceller characteristics and delay time. For the analysis, a wired drone system and a drone-mounted repeater were manufactured to maintain an altitude of 20m for more than an hour, and a small drone-mounted repeater secured stable communication quality around 500m. Shrinkage was tested. Therefore, as a follow-up study, the evaluation of securing the right to control by linking the wired communication repeater drone system with the disaster drone is proposed.
