Mesh wireless ad hoc network equipment system and advantages

In the social environment where various emergencies occur frequently, the demand for emergency communication equipment by the state and society is growing. Improving efficiency and reducing safety accidents are the most important issues for the security industry. However, the traditional communication network cannot meet the actual needs. Emergency control requirements. In the face of such a situation, Mesh wireless ad hoc network came into being.

The wireless ad hoc network adopts Mesh technology as a whole. It is a temporary multi-hop autonomous system composed of a group of mobile nodes with wireless transceivers. It does not depend on the preset infrastructure, in military and civil aspects. Civilian aspects have broad application prospects and are hot issues in current network research.

The MESH wireless ad hoc network can be divided into three categories according to the system structure, mainly the different node functions, including the backbone Mesh structure, the client Mesh structure, and the hybrid structure.

Backbone mesh Mesh structure: formed by Mesh router mesh interconnection, and the wireless Mesh backbone network is connected to the external network through the Mesh router. In addition to the gateway and relay functions of the traditional wireless router, the Mesh router also has a routing function that supports Mesh network interconnection, and can obtain the same wireless coverage with much lower transmission power through wireless multi-hop communication.

Client Mesh structure: A small peer-to-peer communication network is formed by interconnection between Mesh clients, providing point-to-point services between user equipments. The Mesh network user terminal can be a user equipment equipped with a wireless network card and an antenna, such as a laptop computer, a mobile device, or a PDA. This architecture is actually an Ad hoc network that provides a communication support without the inconvenience of using existing network infrastructure.

Hybrid structure: The Mesh client accesses the new network formed by the backbone Mesh network through the Mesh router. This structure provides connection with other network structures, enhances connectivity, and expands coverage.

Then, different from the traditional communication equipment, what are the advantages of the urban emergency deployment control communication system composed of Mesh self-organizing network equipment?

Advantages 1: Strong transmission capability: The wireless transmission between nodes adopts MESH modulation technology, which can realize single-point transmission distance with line-of-sight distance of 50-70 km or single-point transmission distance of non-line-of-sight 1-5 km.

Advantage 2, the management is intuitive and clear: each MESH wireless ad hoc network radio has built-in web interface full Chinese network management software. It can realize the management and monitoring function of the wireless self-organizing network equipment of the whole network.

Advantage 3, self-contained positioning function: After positioning by Beidou (or GPS), its position information can be transmitted to the command information terminal of the command vehicle or the off-car commander through the wireless ad hoc network system. Real-time positioning of the position of each field member and drone in the vehicle or off-board commander.

Advantage 4, strong anti-destructive performance: This system is a centerless self-organizing network structure, which can support up to 16 nodes in the same frequency network. The network topology can be changed in real time according to the actual situation of the task and the actual location between the nodes, and the network can be automatically networked. In the network, any one of the devices can implement the self-organizing network function. If any device in the group is dropped, the corresponding device will continue to communicate within the effective antenna coverage to ensure that the network does not drop.

With its powerful networking technology, wireless ad hoc network perfectly eliminates the defects caused by traditional wireless networks and promotes the wide application of wireless networks.
