Over-the-horizon wireless transmission at sea

Industry overview

my country is a large maritime country, with a vast sea area, and the complex and volatile maritime environment determines that offshore operations are an industry with high risk of accidents. In order to strengthen the ability to respond and deal with maritime emergencies, and to protect the safety of maritime operations and personnel, it is imperative to build a complete maritime emergency communication system and search and rescue command communication platform.

Application requirements

my country’s widely used marine communication systems mainly include maritime wireless communications, marine satellite communications, and shore-based mobile communications. Together, they form a communications network that basically achieves full coverage of the ocean. The system can guarantee the daily communication between ships-coasts and ships-ships in offshore, open sea and ocean. It is widely used in marine transportation, maritime supervision, marine aquaculture, environmental monitoring, marine scientific research, and oil and gas exploration and exploitation.

Introduction to the features of maritime wireless communication solutions

1. Intelligent network, namely dynamic networking, decentralization, easy scalability, etc.

Ultra-long-distance wifi module has no center fast networking: no need to carry out network planning and configuration in advance, and automatically build a network. When other nodes are added to the existing one, they will merge with the original 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 when facing a changeable, complex, and flexible environment. In the actual use process, if the node suffers an accident that causes the service to be interrupted, the network will re-select a link to continue to transmit data to ensure the normal operation of the service.

Easy to expand: The new wireless autonomous network can be directly connected to the original network; if a node is outside the network coverage, other nodes can also be used as relay points to allow the node to access the network.


Intelligent Networking of Maritime Transmission

2. Ultra-long distance wifi module with high bandwidth and long distance

The equipment has the characteristics of high bandwidth and long distance. The point-to-point transmission distance can reach more than 10KM, and the peak rate can reach more than 150Mbps. With this feature, it can support the transmission of a variety of data.

3. Security and encryption

Wireless transmission has extremely high requirements and sensitivity for network security and data encryption. The following strategies and methods can be provided:

The unique MAC address of the network node and the hardware device is bound;

Network identification code to distinguish the legitimacy of nodes in the local area network;

AES128 or AES256 encryption technology can be selected to make the entire network safe and reliable;

In addition, before the data enters the network, third-party equipment is used to improve the protection level.
