Overview

The IoT Gateway is the core edge device bridging the sensor layer and network layer, integrating heterogeneous network convergence with intelligent data processing. Lingqi’s IoT gateway innovatively combines LTE cellular, Wi-Fi, Bluetooth BLE, Z-Wave, Sub-G, and LoRa communication modules in a single unit, supporting wired and wireless, near-field and long-range, public and private network communications. It is designed for smart energy, smart buildings, and industrial IoT scenarios.

Running on Linux/OpenWrt, the gateway provides a complete SDK and API suite supporting C, Python, and Node.js for secondary development. The embedded edge computing engine supports rule-based logic and script execution, enabling local data storage, decision-making, and device interlocking even when offline. The device supports MQTT, CoAP, and HTTP/HTTPS protocols for one-click connection to Alibaba Cloud IoT, AWS IoT, Huawei Cloud, and other major cloud platforms. The PBox1120-4G variant offers a compact form factor with built-in 4G connectivity for cost-sensitive deployments.
