Flexible Networking

The network is flexible, can be quickly deployed/dismantled, and is basically not restricted by terrain; it can be mounted on various platforms. In unpredictable conditions of location, time, and intensity, it can provide effective information transmission for conflicts or emergencies, offering various services to military, civilian, and other users.

Large Communication Capacity

Large communication capacity, good quality, high reliability, capable of providing stable communication for a wide range of users across multiple mission areas.

Flexible Applications

Widely applicable, extensively used in land, sea, air, and both military and civilian fields. Can quickly build various dedicated networks with strong adaptability.

 

Typical Applications of Satellite Communication

Emergency Communication

In the event of a major incident, a temporary communication system is established to ensure that leaders at all levels of the emergency system can timely grasp the situation at the incident site by viewing returned video, voice, data, and other information at the corresponding emergency command center; and to monitor, analyze, and make decisions on the development of the situation; ensuring the deployment, command, and scheduling communication of personnel and resources handling the incident at the center and surrounding areas.

 

 

Emergency Command Communication Vehicle: Aimed at the scene, mainly used for real-time collection of on-site information, constructing temporary regional communication coverage, providing communication support and interconnection for military and related departments, transmitted through the satellite communication center.

Drone Reconnaissance System: Used to scout the situation on-site, providing intelligence support for emergency command.

 

Remote Education and Telemedicine

 

Telemedicine:Enables telemedicine activities, including remote diagnosis, expert consultations, information services, online examinations, and remote communication. The satellite communication-based telemedicine system is used to provide remote video medical guidance for emergency rescue in remote areas without internet access, user-dispersed areas, and disaster sites.

 

Remote Education:Used to provide remote video teaching in remote areas without internet access and where users are dispersed. Achieves real-time and non-real-time broadcasting of audio and video teaching content and interaction between teachers and students.

Introduction to Self-organizing Network Products

Existing emergency communication methods each have drawbacks.

The "4 + 1" emergency communication plan refers to a special communication mechanism established by organizing communication resources and equipment when responding to natural or man-made emergencies (such as floods, earthquakes, wars, terrorist attacks, etc.) when existing public communication facilities may be paralyzed or congested. The four commonly used communication methods (4G, 5G cellular public network, 4G, 5G cellular private network, 370M police digital cluster (PDT), satellite communication) all have drawbacks. An emerging and effective supplementary method: broadband self-organizing network.

 

Domestic broadband self-organizing network and intelligent wireless (AIW) collaborative self-organizing network.

In addition to traditional self-organizing network features such as self-organization, self-relay, and network fault self-healing, AIW collaborative self-organizing network can transform the "communication pipeline" into an "intelligent network" by introducing intelligent spectrum collaboration mechanisms. It is a future fully distributed, self-organizing, and strongly collaborative flat intelligent wireless broadband communication network.

 

Features

  • Concurrent transmission of multiple messages.
  • Significantly increases network traffic.
  • High real-time resource collaboration.
  • Sustained multi-hop traffic.
  • Autonomous negotiation for reuse.
  • Achieve larger scale networking.
