The lora module ofour lora pro series and the wireless module of SV series have been widelywelcomed in the market, and have received many customers' praise. However, ourtwo series of modules have a mesh network mode, so many customers will ask us,what is a mesh network? What are the characteristics of the module's mesh mode?

What is a mesh network?

Wireless Meshtechnology is a new wireless network technology that is completely differentfrom traditional wireless networks. In a traditional WLAN, each client accessesthe network through a wireless link connected to an access point (AP). Tocommunicate with each other, the user must first access a fixed AP. Thisnetwork structure is called a single. Jump the network. In a wireless Meshnetwork, any wireless device node can act as a router at the same time. Eachnode in the network can send and receive signals, and each node can directlycommunicate with one or more peer nodes.

The biggestbenefit of this architecture is that if the nearest AP is congested due toexcessive traffic, the data can be automatically rerouted to a neighboring nodewith less traffic. And so on, the packet can continue to be routed to the nextnode closest to it according to the network, until it reaches the finaldestination. This access method is multi-hop access.

For the most vividexample, we often send emails to customers in our daily work, but the mail isnot sent directly from our mailbox to the customer's mailbox. Instead, it issent from one server to another through a router. Route forwarding is deliveredto the customer's mailbox. This is the typical mesh network.

The mesh mode inour wireless module is based on the characteristics and advantages of the meshnetwork, and then independently developed the working mode.

What are the characteristicsof NiceRF's Lora module mesh mode?

Inour self-developed MESH mode, the lora module can be configured into nodes androutes through different modules, and form a MESH network as a whole to realizepoint-to-point and point-to-multipoint transmission. The node segment moduleconfigured as Node mode is similar to standard communication. The routingmodule of the router is configured to forward data in the same network to solvethe problem that the distance of a single point-to-point transmission isinsufficient in many practical applications, and there is no limit to thenumber of routes in the entire network. When the mesh mode is enabled, the loramodule can form long-distance and no-blind data communication.

How does Meshmode form long-distance and no-blind data communication?

Our engineersuse the relay lora module to forward data to ensure that all lora modules canreceive data and there are no signal dead zones for any modules. As shownabove, Center is the starting point of data, Node is the end point of data, andRouter is the relay; when the center starting point lora module wants to senddata, no matter how far, there will be Router relay lora module to forward thedata of the starting lora module. , thereby forming a long-distance and noblind zone data communication.
