RM45x4 DONYX 4G Router

Core Purpose

This device is designed to deliver stable internet connectivity in demanding environments. It uses four independent cellular modules working together to maintain a constant connection. This setup helps prevent downtime and keeps systems online even when one network fails.

Connectivity and Communication

The router supports simultaneous connections across multiple cellular modules, allowing traffic to be balanced efficiently. If a connection drops, the system automatically switches to another available link. It can also fall back to Ethernet or Wi-Fi, ensuring uninterrupted access across different network types .

Monitoring and Reliability

The device continuously monitors connection health and can take actions like rebooting or switching networks when needed. SIM management allows automatic switching between operators and scheduled usage. This ensures consistent performance and protects against connectivity issues caused by network or SIM failures .

Security

Secure data transmission is supported through VPN technologies such as OpenVPN and IPsec. This enables safe communication between remote locations and central systems. Additional protection mechanisms help defend against unauthorised access and common network threats.

Power and Environmental Suitability

The router operates within a 10–30V DC power range, making it suitable for various industrial setups. It is built to function in extreme temperatures from –40 °C to +65 °C. The aluminium enclosure adds durability for use in harsh environments .

Expansion and Integration

The device includes five Gigabit Ethernet ports for connecting multiple systems and supports dual-band Wi-Fi for local access. Industrial interfaces like RS485 and digital inputs allow integration with external equipment. A built-in GNSS module provides accurate location tracking for mobile and remote deployments

Product Variants

The RM45x4 is available in LTE CAT.4 and CAT.6 versions, both featuring four LTE modules along with advanced failover, load balancing, GPS, and robust VPN capabilities. CAT.4 provides up to 150 Mbps per module, while CAT.6 delivers up to 300 Mbps per module for higher-speed, data-intensive applications.
