Industrial-Grade LTE Gateway with Wide Temperature Support

The GW-8475NRL is an industrial RS-485 LTE gateway equipped with Category 4 LTE connectivity, supporting up to 150Mbps download and 50Mbps upload speeds. Designed for harsh environments, it features a wide operating temperature range of -20°C to 60°C, making it ideal for roadside cabinets, factories, and utility deployments.
 

Dual SIM + eSIM with Automatic Failover

With built-in dual Nano SIM slots and an embedded eSIM, the GW-8475NRL ensures continuous connectivity through automatic failover switching. If the primary network connection drops, the system seamlessly switches to an alternate SIM or eSIM profile to maintain uninterrupted data transmission. WAN + LTE failover further enhances network availability for mission-critical systems.
 

Wi-Fi 5 and Bluetooth Connectivity

Featuring an AC1200 dual-band Wi-Fi 5 module (2.4GHz or 5GHz selectable) based on the NXP 88W8997 chipset, the gateway can provide wireless hotspot access for field technicians or edge devices. The integrated Bluetooth support enables the gateway to function as an IoT hub for sensors, beacons, and short-range communication.
 

RS-485, Modbus Protocol, and DIDO Control

The GW-8475NRL comes with a serial RS-485 interface supporting Modbus RTU/TCP protocols, configurable for half or full duplex. It also includes four DIDO ports, allowing it to interface with alarms, signal lights, and machinery controls—making it a flexible solution for industrial automation, energy monitoring, and traffic systems.
 

VESA Mounting for Easy Installation

Designed with VESA mounting compatibility, the device can be easily installed on factory walls, equipment enclosures, or in transportation systems, streamlining integration into industrial or mobile environments.
 

Open Platform with Debian Linux

Built on a Debian-based open architecture, the GW-8475NRL provides developers and system integrators with the flexibility to deploy custom applications. It supports popular IIoT frameworks such as Node-RED, MQTT, and Docker, and allows OTA firmware updates and API-based management for easier integration and maintenance.
 

Application Scenarios

The GW-8475NRL is engineered for a broad range of Industrial IoT deployments:

• Factory Automation: Integrates with PLCs, air quality sensors, and IP cameras to monitor production lines, detect process anomalies, and trigger local alarms via DIDO outputs.

• Smart Transportation: Enables remote control of traffic signals, real-time bus stop monitoring, and roadside equipment connectivity with 24/7 LTE access.

• Energy Management: Ideal for solar power plants, battery energy storage systems (BESS), and substation telemetry, supporting redundant LTE links for reliable data backhaul.

• Infrastructure & Utilities: Powers remote water treatment, environmental sensing, and transportation IoT nodes in smart city or infrastructure networks
