Product Specifications

Technical details and manufacturing context for IoT Gateway

Definition
An IoT Gateway is a physical device or software program that serves as the connection point between the cloud and controllers, sensors, and intelligent devices. It aggregates sensor data, translates between sensor protocols, processes data locally before sending it forward, and provides a secure communication channel to the cloud or data center. It acts as a bridge, enabling disparate IoT devices with different communication standards to connect and communicate effectively over a network. The gateway typically includes a processor (e.g., ARM Cortex-A53), RAM (1–4 GB), storage (8–64 GB), and supports various WAN interfaces (1–2) and LAN interfaces (4–8). It operates in a temperature range of -40 to 85 °C, with humidity 5–95% non-condensing, and power input of 9–36 VDC. It may have ingress protection ratings from IP30 to IP65 depending on enclosure. Dimensions are approximately 150×100×30 mm, and weight ranges from 0.5 to 1.5 kg without antennas. It supports wireless protocols such as Wi-Fi 4/5, BLE 5.0, Zigbee 3.0, and LoRaWAN 1.0.3, and may carry certifications like CE, FCC, and RoHS. These specifications are reference ranges; verify model-specific values with the manufacturer.
Working Principle
The IoT Gateway operates by collecting data from various field devices (sensors, actuators) using local communication protocols like Zigbee, Bluetooth, Modbus, or LoRaWAN. It then performs protocol translation, converting the data into a standard internet protocol such as MQTT, HTTP, or CoAP for transmission over Ethernet, Wi-Fi, or cellular networks to cloud platforms. It often includes local processing capabilities for data filtering, aggregation, and basic analytics to reduce bandwidth usage and latency. Security functions like encryption, authentication, and firewall protection are typically implemented at the gateway level.
