The KNOT Embedded LTE4 is a compact yet powerful industrial LTE gateway designed for system integrators, automation specialists, and IoT system builders. It fits into tight spaces, mounts directly onto a DIN rail, and offers reliable LTE Cat4 connectivity with Bluetooth and GNSS support.
Use it as a primary gateway, backup link, or IoT data collection node: everything is powered by RouterOS for maximum flexibility.
Powered by RouterOS: full network stack, VPN, firewall, SMS control and notifications, automation, remote management, and much more.
The device requires external antennas: choose the models suited to your environment and customize the KNOT to meet your specific needs.
The KNOT Embedded LTE4 is designed for environments where space is limited but reliability is essential:
• Smart city infrastructure (parking, sensors, metering)
• Monitoring of coffee vending machines and other devices
• Industrial automation cabinets
• Environmental and utility monitoring
• Vehicle or asset tracking with GNSS
• Retail kiosks, payment terminals, digital signage
• Backup LTE connectivity for existing Ethernet devices
• IoT gateways for BLE sensors and beacons
Whether you're building a new system or adding LTE technology to an existing setup, KNOT Embedded LTE4 fits right in. It's easy to integrate, easy to deploy, and designed to operate in harsh environments—from smart city deployments to industrial automation and mobile tracking.
