You've got sensors, field equipment, or remote devices that need a connection you can actually trust — and a way to manage them without driving to each site. The S400 handles that. Semi-rugged Cat 6 LTE modem with dual SIM means one carrier drops, the other picks up. Wi-Fi 5 covers your local IoT devices. Zero-trust security is baked into the 3-year NetCloud Essentials subscription, not bolted on after something goes wrong. Plug in the included AC adapter, screw on the antennas, and you're live. Manage everything from anywhere through Ericsson NetCloud Manager
