Key Specifications

The ICR-4103 series are high-performance industrial grade 4G-LTE cellular routers. They are designed to offer fast connectivity over cellular network for industrial applications. ICR-4103’s Ethernet ports can allow up to 3 Ethernet devices link to the cellular network, provides dual SIM cards and 1 Ethernet WAN port that can automatically re-connect and auto-switch to offer the cellular network redundancy and ensure uninterrupted connectivity. The ICR-4103 cellular router is integrated with WAN, LAN, SIM, VPN, Firewall, built-in DI/DO and Serial port services. In addition, ICR-4103 uses the highest level of industrial grade design for connection in the most demanding environments and is an ideal solution for Industrial Internet of Things (IIoT) and M2M(Machine-to-Machine) applications, such as remote control and monitoring, bus ticketing collection system, CCTV, SCADA, digital signage, kiosk and intelligent traffic systems.
