868MHz 915MHz Lora Mesh Module E52-900NW22S 22dbm Long Distance 2.5Km Automatic Routing Antenna Stamp Holes/Ipex

Description

• LoRa MESH: Using advanced LoRa modulation method, it has the advantage of long-distance anti-interference, greatly improving the coverage of the entire MESH network;Super large network capacity: the theoretical number of LoRa MESH network is as high as 65535, and the proposed network size is about 200
• Automatic routing: When initiating a data request, each routing node can automatically initiate connections with surrounding nodes to determine the data transmission path, without the need for the coordinator to participate in path planning; Network self-healing: When a link fails, the routing node re-establishes a new path after several communication attempts fail;
• Multi-level routing: Routing nodes can automatically transmit data to lower-level routing, and the automatically generated routing table controls the transmission direction of data;Path optimization: Routing information will be continuously and automatically updated and optimized with data transmission in the network to ensure the stability of the entire network; Avoidance mechanism: CSMA avoidance mechanism can greatly reduce the possibility of air signal collision;
• Communication methods: Supports four communication methods: Unicast, Multicast, Broadcast and Anycast; channels, and the channel spacing is 1 MHz;E52-900NW22S module frequency range: works at 850.125 ~ 929.125 MHz, supports 80 channels, and the channel interval is 1 MHz;Decentralization: The entire network is composed of only two types of nodes: terminal nodes and routing nodes,and there is no need for a central node or coordinator to participate in network management;
• Multiple verification: ensure the reliability and accuracy of the data transmission process;High throughput: The entire network is combined in time and space to achieve high concurrency performance;Remote configuration: Supports remote changes of basic communication parameters of the entire network.

E52-900NW22S is a wireless serial port LoRa MESH networking module based on LoRa spread spectrum technology. The
maximum output power is +22 dBm, the maximum air rate can reach 62.5K, and the maximum supported baud rate is 460800 bps. The operating frequency range of the E52-900NW22S module is 850.125~929.125 MHz (default 868.125 MHz).
E52-900NW22S adopts the new LoRa MESH networking technology, which has the functions of
decentralization, self-routing, network self-healing, multi-level routing, etc. It is suitable for smart home and industrial
sensors, wireless alarm security systems, building automation solutions, Smart agriculture and other application scenarios.
