As a large maritime country with a vast sea area with a coastline of more than 18,000 kilometers. Marine environment is complex and changeable, which determines that Marine fishery and Marine operation become the industry with high incidence of accidents. According to the relevant state departments, it is imperative to build a sound early warning, search and rescue command and communication platform for Marine safety operations in order to strengthen the capacity to respond to emergencies and emergencies in Marine operations, protect the safety of life and property of personnel engaged in Marine activities, maintain regional stability and political stability in the ocean, and promote the sustained, healthy and steady development of the Marine economy.

The complete Marine communication system mainly includes Marine wireless communication, Marine satellite communication and shore-based mobile communication, which together constitute a communication network that basically realizes the complete coverage of the ocean. The system can guarantee the daily communication of offshore, offshore and ocean-going ships. In the fields of Marine transportation, oil and gas exploration and exploitation, Marine environmental monitoring, Marine fisheries, mariculture and Marine scientific research, China has provided relatively reliable, accurate, timely and safe communication infrastructure.

Technical characteristics of Marine wireless AD hoc network transmission system, Fast networking without center: After the device is powered on, it quickly searches for and discovers other nearby devices and automatically builds a network without prior network planning and configuration. When other nodes are added to the existing network, the new device merges with the existing network through direct connection or jump to form a larger network, so that the normal operation of the entire network does not depend on any node.

Reliable network transmission: The frequency can be flexibly configured, so that the device can still ensure normal communication and data services in the face of changing, complex, and flexible environment. If services on a node are interrupted due to an accident, the network selects another link to continue data transmission to ensure normal service running.

Easy to expand: new wireless autonomous network devices can be directly connected to the original network; If a node is not covered by the network, you can use another node as a relay point to connect the node to the network.

In Marine wireless AD hoc network transmission system, wireless broadband network is often needed to realize voice, video and data networking and interworking. Its functions must meet the following requirements:

1. Complete AD hoc networking: there is no need to set the central point or relay point of the network, and the network can be automatically formed by energizing;

2. Network omnidirectional high broadband: high gain antenna is used to ensure the omnidirectional bandwidth under the condition that the relative position of the vehicle is often changed in the process;

3. Excellent network self-healing ability: some individuals in progress are out of the range of connection, when re-entering the range, automatically establish a connection;

4. The network topology can be arbitrarily deformed and folded: the whole network connection is not affected by the relative position movement of relay points, and can be arbitrarily deformed and folded.

Suntor team have formed the product joint development with institutions. In long-distance high-speed wireless transmission area, Suntor has more than ten national invention patents, has a wealth of successful cases and professional technical team. Suntor wireless AD supported network transmission equipment can be applied to offshore oil platforms, fishing boats, merchant ships, government ships, cruise ships, ferries, Marine surveillance ships, coast guard ships, research ships and other large offshore platforms to realize high-speed remote transmission between point-multipoint and multipoint, which has the technical advantages of breaking through the limitations of earth curvature and realizing high-speed transmission beyond visual distance.
