Introduction

The OnCell G4308-LTE4 Series is a reliable and powerful secure cellular router with global LTE coverage. This router provides reliable data transfers from serial and Ethernet to a cellular interface that can be easily integrated into legacy and modern applications. WAN redundancy between the cellular and Ethernet interfaces guarantees minimal downtime, while also providing extra flexibility. To enhance cellular connection reliability and availability, the OnCell G4308-LTE4 Series features GuaranLink with dual SIM cards. Moreover, the OnCell G4308-LTE4 Series features dual power inputs, high-level EMS, and a wide operating temperature for deployment in demanding environments. Through the power management function, administrators can set up schedules to fully control the OnCell G4308-LTE4 Series’ power usage and minimize power consumption when idle to save cost.

Designed for robust security, the OnCell G4308-LTE4 Series supports Secure Boot to ensure system integrity, multi-layer firewall policies for managing network access and traffic filtering, and VPN for secure remote communications.
