"Wi-Fi signals are sent to our solar powered aircraft and Wi-Fi is everywhere on the road, in the car, in the wilderness, or on the flight." At the 18th annual meeting of China Association for Science and Technology National Science and Technology Workers Innovation and Entrepreneurship Competition, the Northwestern Polytechnical University Zhouzhou team developed by the team "Solar Wi-Fi UAV" won the gold medal. The establishment of low-cost "air base station" instead of high-cost ground base stations, wireless connectivity anytime, anywhere is possible. The highlight of this project is the combination of solar energy, drone and wireless router with three social hotspots, using solar energy as self-powered energy source and unmanned aerial vehicle (UAV) as a durable and blank platform combining with Wi-Fi technology to build an air base station. Single or multiple base stations for regional coverage, the formation of a flexible mobile Internet air broadband communications infrastructure. In the complex terrain, especially in the desert areas to build ground-based base station into the high cost, narrow channel, to ensure good signal is a difficult task. In 2013, when working with businesses, Professor Zhou Chau inspired by the combination of solar, Wi-Fi and WPI-UAV. If it is possible to establish a base station in the sky and send a communication signal to the ground instead of a ground base station Become a messenger of the sky, you can make Wi-Fi signal in the desert can flow smoothly. Over the past few years, the Zhouzhou team conducted flight tests in Xinjiang and Tibet successively, overcoming various environmental difficulties and completing single-machine and dual-plane Wi-Fi coverage / relay experiment and achieved success. At present, the project has achieved three firsts in China: the first all-winged layout solar drone, which consumes less energy than rotary-wing aircraft, and achieves the aerodynamic and energy-laying efficiency while being the optimal design technique. The first film drone, good film flexibility, laying efficiency, and light weight, weighing only 15kg, an adult can easily pick up. The first to complete stand-alone, dual Wi-Fi coverage / relay experimental verification of the UAV. The most practical use of this technology is to solve the actual needs of remote access to the Internet. Can also be used for emergency relief, search and rescue operations in disasters such as earthquakes, the helicopter's visual range is small, but also by natural factors such as dark and thus interfere with the search and rescue progress. The use of solar Wi-Fi UAV long voyage advantage, as the air information platform, rapid positioning of life traces; in the field of rescue, but also to solve the trapped people with the outside world difficult.
