Wireless broadband ad hoc radio station – a wireless broadband communication method that does not rely on any communication network

With the vigorous development of wireless communication technology, various communication products have emerged in an endless stream and have become an indispensable part of people’s daily lives. Most of the existing communication products rely on existing communication means such as wired communication, base station mobile communication (4G, 5G) and satellite communication to play a role, but they are stretched in some emergency scenes with relatively complex environments.
Wireless broadband ad hoc network products are broadband ad hoc networks based on software radio (SDR) technology, multi-carrier modulation OFDM, smart antenna MIMO and mobile ad hoc wireless network Mobile Ad Hoc Network (MANET). It is currently the most powerful wireless ad hoc network, providing real-time high-definition video, multi-channel serial data, two-way intercom voice and broadband Ethernet connection up to 180Mbps and up to 100 kilometers away, and is an ideal choice for critical private network wireless communications.

Through the interconnection of wireless broadband self-organizing network node products, we can build an “air-space-ground” grid military communication network, command information nodes for comprehensive command and coordination, and combat information nodes for efficient collaborative command and control. Through the distributed holographic communication system, the information nodes of each combat unit can realize: enemy information sharing, battlefield situation awareness, real-time military situation consultation, and instant task allocation and combat command issuance, thereby realizing the integrated and efficient coordination of each combat unit.

No support : The radio station does not need to rely on any basic communication facilities (optical fiber, operator base stations, satellites, etc.). It can quickly form a local area network by sending and receiving radio signals, and has strong flexibility;
No center : There is no strict control center in the network, each node can communicate reliably, and nodes can join and leave the network at any time. The failure of any node will not affect the operation of the entire network, and it has strong anti-destruction ability;
High rate : The equipment supports a maximum transmission rate of 70Mbps and 40M bandwidth allocation, and can support complex business communications such as multi-channel high-definition video command and dispatch;
Long distance : Under the condition of air-to-ground line of sight, the maximum communication distance between two nodes can reach 300km, and several devices can easily cover a large area to form a large-scale local area network.

Fleet linkage, self-organization and coordination

The vehicles in the convoy are equipped with self-organizing network vehicle-mounted nodes. After being powered on, a broadband wireless transmission network with multi-hop relay, multi-service, high reliability and high mobility can be established in a very short time. It ensures the simultaneous linkage communication of multiple vehicles and provides independent, safe, efficient and timely voice communication, data transmission and video monitoring services.
The airborne nodes can be used as wireless self-organizing network commanding height enhancement coverage points to further expand the combat radius and provide the latest combat situation and situation forecasts for each combat unit.

Fleet formation, land and sea connection

In view of the wireless communication environment at sea, shipborne nodes are deployed on ships to quickly build a broadband wireless network with high reliability, high mobility, strong anti-destruction and anti-interference, and beyond line of sight transmission. Ensure flexible networking and multi-hop transmission between shore-based and ships, and between aircraft and ships, and provide users with safe, reliable, stable, and timely multimedia integrated transmission services such as voice, data, and video.

 Border situation, monitoring and perception

Applying broadband wireless ad hoc network communication technology to the border situation monitoring system can self-organize and build a distributed holographic communication system, realize wireless real-time backhaul through single-hop direct or multi-hop relay, real-time transmission and comprehensive application, realize the combination of fixed monitoring and patrol monitoring, information transmission and command and dispatch, and can transmit border situation information back in the first time, providing strong support for real-time information interaction between the front and rear, and remote unified command and dispatch, thereby further enhancing the information-based comprehensive technical defense and combat capabilities of border situation monitoring.

 Fire emergency, rescue command

Holographic network nodes of different forms can be quickly deployed inside and outside the firefighting and rescue site to efficiently form a network. Especially for the complex internal and underground structures of the fire scene buildings, by building a wireless multi-hop grid, the poor communication or blind spots caused by obstruction can be effectively solved to ensure that “there must be a network wherever there are people”, and to ensure reliable and timely wireless communication for firefighters
        inside and outside the fire scene. At the same time, through the mobile nodes carried by fire trucks and drones, fire detection and prediction and real-time monitoring of the fire scene can be achieved. The distributed holographic communication system can further expand the network coverage, effectively solve the communication in “high-low-large-scale” scenarios such as underground and aboveground fire scenes, inside and outside buildings, and deep in buildings, and facilitate on-site command of firefighters for on-site coordination, personnel search and rescue, and safe evacuation.
