The MikroTik KNOT LTE4 (EC25-EU&KNe) is a compact, industrial-grade IoT gateway engineered for reliable connectivity in space-constrained environments. Designed for flexibility, it serves as an ideal solution for remote telemetry, industrial automation, and smart infrastructure (such as vending machines or retail kiosks). It combines cellular backhaul, precise GNSS positioning, and local sensor data collection via Bluetooth, all managed through the powerful RouterOS v7 operating system.
