Product Descriptions

E52-400/900NWxxS is a wireless serial port LoRa MESH networking module based on LoRa spread spectrum technology, with a maximum output power of 22dBm/30dBm, a maximum air speed of 62.5K, and a maximum support baud rate of 460800 bps. The working frequency range of E52-400NWxxS module is 410.125-509.125 MHz (default 433.125MHz), and the working frequency range of E52-900NWxxS module is 850.125-929.125 MHz (default 868.125 MHz).

E52-400/900NWxxS adopts the new LoRa MESH networking technology, which features decentralization, self routing, network self-healing, multi-level routing and other functions. It is suitable for smart homes, industrial sensors, wireless alarm security systems, building automation solutions, smart agriculture and other application scenarios.

Product Features

⚫  LoRa MESH: Adopting advanced LoRa modulation method, it has the advantage of long-distance anti-interference, greatly improving the coverage range of the entire MESH network;

⚫  Ultra large network capacity: The theoretical number of LoRa MESH networks can reach up to 65535, and it is recommended to have a network size of around 200.

⚫  Decentralization: The entire network is composed of only two types of nodes, terminal nodes and routing nodes, without the need for a central node or coordinator to participate in network management;

⚫  Automatic routing: When initiating a data request, each routing node can automatically establish connections with surrounding nodes to determine the data transmission path, without the need for a coordinator to participate in path planning;

⚫  Network self-healing: When a link fails, the routing node re establishes a new path after several failed communication attempts;

⚫  Multi level routing: Routing nodes can automatically transmit data to lower level routers, and the direction of data transmission is controlled by an automatically generated routing table;

⚫  Path optimization: Routing information will be continuously updated and optimized automatically with data transmission in the network, ensuring the stability of the entire network;

⚫  Avoidance mechanism: CSMA avoidance mechanism can greatly reduce the possibility of airborne signal collisions;

⚫  Communication methods: Supports four communication methods: Unicast, Multicast, Broadcast, and Anycast;

⚫  E52-400NWxxS module frequency range: operates in the frequency band of 410.125~509.125 MHz, supports 100 channels, with a channel spacing of 1 MHz;

⚫  E52-900NWxxS module frequency range: operates in the 850.125~929.125 MHz frequency band, supports 80 channels, with a channel spacing of 1 MHz;

⚫  Multiple verification: ensuring the reliability and accuracy of the data transmission process;

⚫  Encryption transmission: Special encryption algorithms are used during data transmission to ensure the security and privacy of the data;

⚫  High throughput: The entire network combines time and space to achieve high concurrency performance;

⚫  Remote configuration: supports remote modification of basic communication parameters for the entire network.
