The Mesh wireless ad hoc network system is a mobile broadband multimedia communication system designed with a new `wireless mesh network` concept. All system nodes can achieve real-time interaction of multi-channel voice, data, images and other multimedia information under non-line-of-sight and fast-moving conditions using the distributed network architecture of the centerless ad hoc network. At the same time, the system supports any network topology, each node device can move randomly and quickly, and the system topology can be quickly changed and updated without affecting system transmission. The overall system is easy to deploy, flexible to use, simple to operate and easy to maintain.

As the year draws to a close, sporadic outbreaks have occurred in many parts of my country, and the raging epidemic has once again tested the emergency response capabilities of local governments. Urban emergency control is once again before us. With the rapid development of my country's overall economic construction, the urban economic system is also growing stronger, and various contradictions and dangerous factors in cities are increasing.

Since the activity site is a full-scale, three-dimensional real-time monitoring site, the Public Security Bureau has deployed multiple drones for real-time aerial monitoring. Due to the complex situation on site, it is required to use wireless methods to transmit images to the command center.

With the rapid development of the social economy, the particularity of construction and enterprise production has led to an increase in the hidden dangers of chemical hazardous materials and radioactive substances leakage, as well as combustion, explosion, and collapse accidents, and the probability of accidents occurring has correspondingly increased. Once a disaster or accident occurs, when firefighters face hazardous environments such as high temperature, darkness, toxicity, and thick smoke, if they rush into the scene without corresponding equipment, they will not only fail to complete the task, but also increase casualties. The 8.12 Tianjin Binhai New Area fire and explosion accident is a painful lesson. As a type of special robot, firefighting robots are playing an increasingly important role in firefighting and emergency rescue.

The marine environment is complex and changeable. In remote sea areas, public network signals often suffer from insufficient coverage or signal interruption, which hinders communication between law enforcement vessels and the command center. As a result, key information such as video footage of the law enforcement site and the location of the target vessel cannot be transmitted in real time. Moreover, the law enforcement area is vast, and traditional monitoring methods are unable to achieve comprehensive coverage, leaving numerous blind spots for illegal fishermen to take advantage of. Therefore, it is urgent to build a highly efficient, stable, and fully covered wireless monitoring system for fishery law enforcement.
