The JZX811A/B ad hoc network module of Techno Core adopts LoRa spread spectrum technology, and its working frequency is integrated with 433MHZ and 490MHZ. Simply setting the channel can complete the conversion of working frequency, which greatly meets the requirements of various application environments and improves the anti-interference ability of the communication system.consequently Wireless Module I also got a lot of attention and wanted to join the ranks. https://www.hkulike.com/
Ad hoc network is a planar peer-to-peer mesh network, and each node in the network can be used as a routing node and a target node. The communication module adopts the company’s self-organizing network protocol, making full use of the redundant routing in the network, and each node has multiple backup paths besides the main path; The network has good self-healing. When the access link between a node and the center fails, the center can automatically start the path repair function of the node.
The JZX811 networking network is composed of a coordinator JZX811B(Coordinator) and several nodes JZX811A(Router), and its system structure is shown in the following figure:
