Recently, a piece of news about the "corrupted code" during the drone performance on the Xi'an City Wall spread across the internet, showcasing the huge commercial potential of drones to the public.

       According to the data from the China Government Procurement Network, the drone performance project for the "Spring Dance in Xi'an City Wall" light and shadow grand event was procured by the Xi'an City Wall Management Committee. Guangdong EHang White Swan Media Technology Co., Ltd. finally won the bid with an event fee of 10.5 million yuan.

       According to relevant sources, EHang White Heron has conducted several drone formation performances in China. Li Zhiyuan, the managing director of EHang White Heron Media Technology, told reporters, "In 2016 during the JD 618 event, EHang Media made its first commercial drone performance marketing. It was very successful, and since then it has been used as an output service." At the 2017 Guangzhou Fortune Global Forum, 1,180 drones of EHang White Heron performed a wonderful drone show over the Pearl River.

       Regarding the drone formation performance at the Xi'an City Wall International Cultural Festival, the official Weibo account of EHang White Egret drones stated: The total number of drone formations was 1,374. The take-off and landing areas were set on the southern gate of the city wall and the areas extending east and west. In the night sky, a spectacular and magnificent large-scale picture spanning approximately 1.2 kilometers in length, 100 meters in depth, and 260 meters in height was formed, and an innovative "dynamic sky curtain" effect was adopted. For safety reasons, the entire performance airspace was limited to the vertical upper part of the city wall, and the width of the performance space did not exceed 12 meters.

       The performance of drones involves high technological complexity. It is precisely in these instances of "garbled codes" that we have come to realize the tremendous commercial value of drone applications. Thus, it can be seen that there is still a considerable market for the commercial application of drones. Shenzhen Shenfang Technology Co., Ltd. focuses on the research and development and sales of wireless transmission products. The COFDM mobile video wireless transmission products developed and produced by them have features such as small size, light weight, anti-interference, and long transmission distance, and are widely used in the field of drone wireless transmission.
