KNOT Embedded LTE4 is a small but powerful unit built for integrators, industrial automation, and IoT system builders. It mounts directly on a DIN rail and offers solid LTE Cat4 connectivity combined with Bluetooth 5.4 and GNSS (GPS, GLONASS, Galileo, BeiDou).
It runs RouterOS, giving you full control — VPNs, firewall, SMS notifications, automation scripts, and remote management. With eSIM + Nano SIM support, GPIO for sensors, Gigabit Ethernet, and PoE-In, it adapts easily to almost any industrial environment.
Use it as:
-
A primary LTE gateway
-
A backup link for Ethernet devices
-
An IoT collection hub for BLE sensors
-
A GNSS-enabled tracking device
Built for harsh environments, small cabinets, smart city gear, and mobile applications.
