Application Mode

Training Exercises
In the field of applications, including scenarios such as daily training, logistics support, and actual battlefield operations, broadband wireless networking systems can quickly establish a battlefield broadband wireless communication network that is mobile, flexible, and highly resilient to destruction. This is achieved under the tactical requirements of full-time and round-the-clock operation, as well as in complex electromagnetic environments. Furthermore, these systems can form an "air-space-ground integrated" three-dimensional command and communication system together with satellites, unmanned aerial vehicles (UAVs), and other platforms. It enables situational awareness, information sharing, and the issuance of commands, which facilitates accurate assessment and rapid command by superior units at all levels, as well as integrated and efficient coordination among various combat units. The system can be widely applied to various areas, including the Navy, Air Force, Rocket Force, and Information Support Forces, and serves as a crucial link in the construction of battlefield data links.

The main application scenarios include:
Team individual soldier interconnection
Interconnection between various combat clusters
Armored Vehicle interconnection
Transport and ensure fleet interconnection
Real-time multimedia data transmission at training bases and shooting ranges
Unmanned equipment (including drone swarms) interconnection
Ship interconnection, etc.


Border and Coastal Defense
The broadband wireless networking system is deployed on various ships, shore-based command centers, shipboard individual soldier, and other combat units, enabling real-time wireless transmission of IP data, HD video, voice, and other multimedia information for all combat units. Through routing updates, communication nodes can be automatically added and removed at any time.

The system establishes a maritime "Island-Ship-Shore" broadband wireless communication network, enabling flexible command and communication across shore-to-ship, island-to-ship, ship-to-ship, and air-to-ship links. Leveraging multi-hop self-organizing networking and automatic relay capabilities, it extends the coverage of coastal and border defense communications. It can also be used as a communication backhaul link solution between land, islands, and ships.

In the actual application of shore-based command system, the transmission distance between the shore-based system and the ship of Mesh broadband wireless ad hoc network exceeds 120km. In the actual application of ship combat unit, the transmission distance between two ships exceeds 60km.


Maintaining Stability and Handling Emergencies
In the event of an emergency, communication vehicles equipped with command nodes rapidly arrive at the scene to quickly establish an on-site emergency command center.

During stability maintenance and incident response operations, individual soldier nodes, vehicle-mounted nodes, deployment nodes, temporarily set up relay nodes, and UAV nodes are swiftly deployed to key locations to form a hybrid topological network structure enabling multi-hop transmission for realize multi-angle monitoring of emergency scene

As the situation develops, the positions of node devices can be adjusted at any time, or additional node equipment can be deployed, with the entire system automatically reconstructing routing.

Fixed nodes are quickly installed on high points of buildings to achieve relay transmission and expand coverage; drone nodes can not only shoot high-definition videos of large-scale scenes, but also provide high-altitude relay.

Relying on satellite, 4G/5G, or 340M systems, the network achieves local access and remote backhaul.

With timely response, rapid deployment, plug-and-play operation, flexible adaptation, dynamic networking, and stable reliability, it serves as critical support for building an on-site broadband emergency communication system.


Fire and Rescue
After the establishment of the national comprehensive fire rescue team, the fire emergency communication guarantee task has undergone profound and huge changes. Especially when carrying out fire fighting and rescue of complex urban buildings and major natural disasters, it brings huge pressure and challenges to the communication guarantee of the rescue site.

Broadband wireless networking, featuring mobility, flexibility, autonomous routing, and multi-hop relaying, serves as a powerful information tool for fire and rescue operations in the new era. It enables image signal coverage inside high-rise and underground buildings-both within and outside structures that have complex layouts and severe signal shielding. At the sites of major natural disasters, it establishes a broadband communication network covering all on-site rescue areas, ensuring communication connectivity among members of the fire and rescue team. By collaborating with high-performance AI head-worn computers equipped with intelligent interconnection software for fire-fighting and rescue, it focuses on addressing the key pain points at fire and rescue scenes: "difficulties in communication coverage and disorganized command order."

In actual firefighting and rescue operations, broadband networking base stations can cover 5 to 8 floors above ground and 1 to 2 floors underground inside complex buildings; after the base station is set up, broadband multimedia service communication coverage distance of more than 80 kilometers can be achieved; in subways and tunnels, JoMesh broadband self-organizing network base stations can achieve communication coverage distance of more than 700 meters; in places where wireless self-organizing network signals are severely shielded and attenuated, guaranteed communication can be achieved through Beidou three short messages.


Forest Fire Prevention
In response to the high mountain terrain and vegetation cover of forest areas, fixed relay nodes are deployed at commanding heights. This allows for the automatic implementation of various network topologies, including chain networks, star networks, and hybrid networks. Through self-organizing interconnection and multi-hop relaying, the unfavorable effects of mountainous obstruction on wireless signals are converted into relay forwarding at commanding heights, thereby extending communication distances and reducing blind spots in monitoring.

Broadband ad hoc network backpack radios and handheld radios are distributed to personnel at forest and grassland fire prevention sites. These serve as user nodes in the ad hoc network, providing real-time fire and personnel monitoring, as well as command and dispatch capabilities.

Working closely with the BeiDou-3 short message system, it ensures that key information can be uploaded at any location, building a comprehensive forest fire prevention solution.

Provide video image and positioning upload services for key areas and daily wartime patrols.


Emergency Rescue
When major disasters or accidents occur, rescue personnel carry self-powered individual portable nodes, outdoor control nodes, drone nodes, etc. to quickly reach the natural disaster emergency rescue site, establish a front-line command center on site, and deploy each node to key locations according to the on-site environment and networking needs.

The front-end node can be connected to the on-site command post through ground multi-hop relay or drone relay, quickly building a broadband wireless emergency communication network at the emergency rescue site, effectively solving the communication problems caused by damage to power and telecommunications facilities, and opening up the "last mile" of wireless broadband access.

Drone nodes can also realize large-scale real-time detection and monitoring of disaster sites, disaster information data transmission and harmful gas detection.

By cooperating with BeiDou-3 short messages, the self-organizing network nodes build a comprehensive command system for natural disaster emergency rescue sites; on-site high-definition video can be transmitted back to command centers at all levels via satellite links, so that commanders can intuitively grasp the actual situation at the disaster site and quickly formulate reasonable rescue plans within the golden rescue time.
