Advantech ICR-3241 industrial 4G LTE router in a compact metal enclosure with two SMA antenna connectors, dual Ethernet ports and terminal-block connectors.

The Advantech ICR-3241 is a 4G LTE Cat 4 gateway for industrial M2M and IoT deployments where IP and serial devices need a dependable cellular uplink. It covers LTE bands B2, B4, B5, B12, B13, B14, B66 and B71, with HSPA+/UMTS fallback. Rated speeds reach 150 Mbps down and 50 Mbps up. Two Mini SIM (2FF) slots under a cover allow failover between carriers. Carrier approvals cover Verizon, AT&T and T-Mobile, and the order code is specified for the North American (NAM) region. In Advantech's order-code table, FirstNet certification is marked for the ICR-3241-1ND, ICR-3241W-1ND and ICR-3241-EL variants rather than this standard ICR-3241. For wired connections, the router has two RJ45 10/100 Ethernet ports with 1.5 kV isolation. A 10-pin terminal block carries RS232, RS485, one digital input and one digital output. Other hardware includes a battery-backed real-time clock, a hardware watchdog, sleep mode and power-ignition support. It takes 9–36 V DC through a 2-pin terminal block. The IP30 metal case has a grounding screw, and the wall-mount kit and DIN clip are both included. The unit meets E-Mark, EN 50155 railway, EN 45545-2 and MIL-STD-810G requirements. At the edge, a 1 GHz Cortex-A8 CPU runs with 512 MB RAM and 4 GB of pSLC eMMC, and 1.3 GB of that storage is allocated to customer applications and data. ICR-OS is Linux-based and supports development in Python, BASH, C/C++, Node-RED and Docker through Router Apps. Advantech's Router App library adds Modbus, DNP3, IEC 60870-5 and MQTT gateways. Security covers WireGuard, OpenVPN, IPsec, GRE and L2TP VPNs, a firewall, RADIUS/TACACS+ and 2FA. Fleets can be managed at scale through WebAccess/DMP. The Advantech datasheet is available for full specifications.
