The Radio Monitoring Station of Guangxi Zhuang autonomous region organized the radio monitoring centers of cities in the Beibu Gulf, such as Qinzhou, Beihai, and Fangchenggang, to carry out Guangxi's first joint radio monitoring of the area.

Carrying out border sea radio monitoring will not only help maintain national territorial security, as well as serve the economic and social development of border sea areas, but also help safeguard the legitimate rights and interests of radio service users in border sea areas.

The Beibu Gulf is the only area connecting China with ASEAN by sea and land. It is the only coastal area in western China and the most convenient seafaring channel for southwest regions.

With the development of the economy, the number of ships, such as maritime passenger ships and freight transportation, has increased, while the volume of wireless communications has also increased dramatically.

The Guangxi Radio Monitoring Station began to carry out radio monitoring of the China-Vietnam border in 2006, and began monitoring the coastline of the Beibu Gulf in 2019.

For the first joint radio monitoring on Beibu Gulf waters, technicians used portable monitoring equipment to observe the marine electromagnetic environment, as well as collected data on key frequency bands through spectrum monitoring and demodulation systems. They focused on the monitoring and analysis of maritime service frequencies, maritime radio signals, as well as ship AIS dynamic information.
