Frequently asked questions about the WG785 Industrial Gateway

The WG785 supports 5G NR, 5G RedCap, 4G CAT4, and 4G CAT1 cellular modules. The 5G/4G versions cover global mainstream TDD-LTE/FDD-LTE bands, compatible with major operators worldwide. For detailed band lists (Europe, North America, Asia-Pacific, etc.), please contact our sales team. Dual Nano-SIM slots (eSIM optional) provide cellular redundancy for always-on connectivity.

Yes, WG785 supports connection to Azure IoT Hub, AWS IoT Core, Alibaba Cloud, Huawei IoT, and WideIOT Cloud via MQTT (JSON format). It also supports OPC UA, Modbus TCP, IEC 104, IEC 61850, BACnet, and HTTP/SQL for flexible cloud integration. TLS encryption and certificate authentication ensure secure data transmission.

5G offers the highest bandwidth and lowest latency for video transmission and real-time control. 5G RedCap provides a cost-effective 5G solution for mid-tier IoT applications. 4G CAT4 delivers downlink 150Mbps / uplink 50Mbps, suitable for most industrial scenarios. 4G CAT1 provides downlink 10Mbps / uplink 5Mbps, ideal for basic IoT and cost-sensitive deployments. All versions support automatic multi-network failover (Ethernet/Wi-Fi/Cellular).

Yes, WG785 features two Nano-SIM slots (eSIM optional) with automatic failover. If the primary SIM loses connection, the gateway instantly switches to the secondary SIM to ensure uninterrupted cellular connectivity. This works in combination with multi-network redundancy (Ethernet, Wi-Fi, 4G, 5G) for maximum reliability.

WG785 comes with a standard 1-year warranty for overseas orders. We provide comprehensive after-sales support including remote technical assistance, firmware updates, and replacement services. Extended warranty options are available upon request. Remote maintenance via WideIOT Device Express is supported for worldwide debugging.

Yes, WG785 is designed for industrial environments with an operating temperature range of -20℃ to 70℃ (extendable to -30℃ to 75℃) and storage temperature from -40℃ to 85℃. The fanless metal casing and IP30 protection ensure reliable operation in harsh conditions including dust, vibration, and electromagnetic interference (EMC Level 4 certified).

WG785 comes standard with 4GB data storage (optional 8GB eMMC). It also supports edge data logging with breakpoint resume functionality. For extended storage requirements, select the “E” option in the ordering code for 8GB eMMC. The gateway supports local programming and data storage at the edge.
