The ICR-W403 is a high-performance industrial grade wireless router.  It combines IEEE 802.11b/g/n/ac WLAN and 4G LTE cellular technologies to provide flexible wireless network connectivity for industrial applications. ICR-W403 provides 3 Ethernet ports and dual SIM cards for failover redundancy, to ensure uninterrupted connectivity.  ICR-W403 provides secure VPN communications, GPS, static and dynamic IP routing of RIP1/2 and OSPF, NAT, port forwarding, Firewall, built-in DI/DO and Serial port services.

Harsh Environments

The ICR-W403 uses the highest level of industrial grade design for use in the most demanding environments, and is an ideal solution for Industrial Internet of Things (IIoT) and Machine-to-Machine(M2M) applications, such as remote control and monitoring, fleet management, bus ticketing collection systems, CCTV, SCADA, digital signage, KIOSK and intelligent traffic systems.


Comprehensive management features are accessable via a web browser, SNMP, a command line interface and  TR069, which provides  diagnostic functions along with auto-configuration  and firmware upgrades.  TR069 is an invaluable tool in the management of fluid networks.
