Introduction
The OnCell G4308-LTE4 Series is a range of all-in-one industrial cellular routers that integrate an 8-port high-performance switch, firewall, and LTE Cat.4 connectivity, making them ideal for connecting multiple devices at remote sites. By avoiding the need for multiple standalone devices, these cellular routers save cabinet space, reduce wiring and configuration complexity, and lower maintenance costs to simplify deployment and maintenance efforts. Designed to act as a wireless backbone for critical industrial applications, they deliver stable Serial/Ethernet-to-cellular connections and ensure optimal reliability with dual SIM failover and GuaranLink cellular auto-recovery. The OnCell G4308-LTE4 Series protects organizations against threats on multiple fronts. Built from the ground up with security in mind, Secure Boot ensures firmware integrity while the advanced firewall with OT protocol awareness safeguards the network from internal and external threats. Meanwhile, Deep Packet Inspection (DPI) detects and blocks forged or malicious packets. Combined, these features deliver comprehensive, multi-level security for critical operations. With MRC Quick Link Ultra, operators gain complete visibility and secure remote control over both the OnCell router and its connected end devices, allowing for faster troubleshooting, minimal downtime, and more reliable industrial operations.
