Introduction
The OnCell 3120-LTE-1 series consists of reliable, secure, low-power LTE gateways with state-of-the-art global LTE Cat 1 coverage. These LTE cellular gateways provide reliable connections from remote serial and Ethernet devices to a cellular network, making it easy to implement your applications for IIoT remote access scenarios. With its efficient power saving features, the OnCell 3120-LTE-1 series reduces power consumption to less than 40 mW in standby mode, which can be controlled via schedules. To improve reliability in industrial environments, the OnCell 3120-LTE-1 features GuaranLink to ensure a robust cellular connection.
