All our products support mesh network! The current communication module works in the 2.4GHz, with a radius of 50 meters, a capacity of 10,000, an airspeed of 1Mbps, automatic network information memory, 1 second network access, one-to-multiple, broadcast, group, APP accessed at any node, and is in line with the Sig HSL model.


The cost is almost the same as that of other wireless communication products. The mesh networking products and technologies are widely used in agriculture, industry, education, medical care, elderly caring, building, etc. MeshIoT has hundreds of sensors, actuators and communicators that can be connected through mesh network.


Mesh network is long expected. In WLANs, each client accesses the network through a wireless link connected to an access point (AP). To communicate with each other, the user must first access a fixed AP. This network structure is called a single-hop routing. In wireless mesh networks(WMNs), any node can act as a router at the same time, send and receive signals, and each node can directly communicate with one or multiple nodes, commonly known as multi-hop routing.


Mesh network features are:



  • Self-organizing

Mesh network nodes and authorized end users can join the network instantly, extend network coverage, and connect to all other nodes.



  • Self healing

If a device in the network fails or is removed from its topological location, the mesh network automatically adapts to this change. Even if the connection between the originator and the peers involves multiple relay devices, the mesh network will find new routes from the sending end to the opposite end.



  • Multi-hop

Each node and end-user device (wireless communication unit) can forward and route data packages to the other node, and can select the best route from the sending end to the opposite end.



  • Peer-to-peer network

Self-organizing networks are usually composed of equal network elements. As long as the distance between the sending end and the opposite end is close enough, the sending end and the opposite end can be directly connected. It is not necessary to go through the central management node.



  • Multi-channel 

Wireless mesh networks use a multi-channel access to ensure that both nodes of the communication work on the same channel. The time axis is divided into beacon intervals. At the beginning of each beacon interval, a time window called ATIM is established. Within the same ATIM, nodes with data to be sent use the same channel as the receiver. The purpose of this multi-channel method is to select a channel with a small traffic load, balance the channel load as much as possible, and reduce the bandwidth wasted by contention and backoff.
