YL-800N (800NS) is a distributed MESH structure wireless ad hoc network module, working in the 433M free frequency band, internal automatic spread spectrum calculation and leading CRC error correction processing. Based on Sx1278 LoRa spread spectrum frequency hopping technology, low bit error rate and strong anti-interference ability. Built-in wireless MESH ad hoc network protocol, users do not need to make any modification to the existing equipment, protocol, and do not need to carry out secondary development of the module to easily realize the wireless ad hoc network.
MESH is a distributed peer-to-peer mesh network, which can make full use of the routing redundancy in the network. It has excellent network self-healing, stability and excellent data throughput. Its networking speed is zero. The device works immediately after power-on, and supports 255-level routing and a large networking scale of tens of thousands of nodes. The physical layer uses many advanced wireless communication technologies such as frequency hopping, adaptive rate, safe and reliable wireless wake-up technology for the entire network, interleaving error correction coding, etc.; the link layer uses intelligent collision avoidance algorithms with excellent anti-interference capabilities.
