Product Descriptions

EWM528-2G4NW20SX/27SX is a wireless serial LoRa MESH networking module based on LoRa spread spectrum technology. It has a maximum output power of+27dBm, a maximum air speed of 253Kbps, and supports a maximum baud rate of 200000bps. The working frequency range of the module is 2400-2500 MHz (default 2400 MHz).

The EWM528-2G4NW20SX/27SX 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;

• 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 connect 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: The CSMA avoidance mechanism can greatly reduce the possibility of airborne signal collisions;

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

• Frequency range: Operating in the 2400-2500 MHz frequency band, supporting up to 200 channels;

• 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.
