Research on Test Method for Low Altitude Wireless Network Signal

Objective: In recent years, with the large-scale construction of large venues, high-rise office buildings, residential quarters, and the development of networked UAV, the demand and complaints of users for air network coverage are increasing. The existing road test instruments are designed for ground coverage based on the mobile app and PC software, which is not suitable for low altitude signals. In order to shorten the test cycle of low altitude network signal and improve the test efficiency, a new low altitude network signal test method is proposed, and a test system suitable for low altitude network signal coverage and quality detection is developed. Methods: The present study investigated a system that uses airborne measuring instrument to complete data acquisition, and returns real-time data to the processing cloud platform through 5g cellular network. The signal quality and capacity of low altitude network are detected on the cloud platform. Results: The test results show that the proposed method and the developed airborne measuring instrument can complete the low altitude network signal test work and effectively improve the test efficiency. Conclusion: The research on test method for low altitude wireless network signal plays an important role in the optimization of low altitude network and fine management of tower base station information.
