In recent years, researches of disseminating wireless network have been conducted\nfor areas without network infrastructure such as disaster situation or\nmilitary disputes. However, conventional method was to provide a communication\ninfrastructure by floating large aircraft as UAV or hot-air balloon in\nthe high air. Therefore, it was difficult to utilize previous method because it\nrequires a lot of time and cost. But it is possible to save money and time by\nusing a drone which is already used in many areas as a small UAV. In this paper,\nwe design a drone that can provide wireless infrastructure using high\nspeed Wi-Fi. After reaching the target area, the drone can provide Wi-Fi using\nwireless mesh network and transmit the situation of local area through attached\ncamera. And the transmitted videos can be monitored in the control\ncenter or cell phone through application in real time. The proposed scheme\nprovides wireless communication of up to 160 Mbps in a coverage of about\n200 m and video transmission with a coverage of about 120 m, respectively.
