Industrial 4G Router ADVANTECH ICR-3231W — cellular connectivity for IoT applications

ADVANTECH ICR-3231W is an industrial 4G router engineered to deliver reliable cellular WAN connectivity for IoT and M2M deployments. It integrates LTE access with secure routing features and interfaces suitable for remote monitoring, telemetry, and device management at distributed sites. The router supports use as a primary or failover WAN link and is designed for installations that require continuous data transmission from sensors, gateways, or edge equipment over cellular networks.

Advantages

The router provides stable LTE cellular connectivity combined with standard routing functions to enable remote access and secure data transfer. Its industrial design supports deployment in diverse environments where wired networks are unavailable or as a redundancy path for existing WAN infrastructure. Integrated management features and compatibility with common IoT use cases simplify commissioning and ongoing maintenance.

Suitable for

• Remote monitoring and telemetry of assets and sensors
• Failover or primary WAN connectivity for branch sites and gateways
• Connecting distributed IoT devices and edge equipment
• Machine-to-machine (M2M) communications in industrial environments

Key specifications

• Cellular connectivity: LTE (4G) for mobile data transmission
• Routing capabilities: secure NAT, DHCP and static routing support
• Interfaces: Ethernet ports for LAN/WAN device integration
• Management: remote configuration and monitoring support suitable for IoT deployments
• Physical design: industrial form factor intended for mounting in equipment cabinets or field enclosures

How to use

Install the router at the site and connect the primary Ethernet links to local network devices or gateways. Insert and activate a compatible SIM card with an appropriate data plan, then configure cellular APN settings and routing parameters via the device management interface. Set up security features such as firewall rules and remote access controls, and verify connectivity by checking the LTE signal and data transmission to the central server or cloud platform.

Recommendations

Place the unit where it receives adequate cellular signal strength, avoid locations with heavy RF shielding, and use suitable antenna placement for best LTE performance. For critical applications, configure the router as a failover WAN or use an external antenna and stable power supply to ensure continuous operation.
