KNOT Embedded LTE4
Industrial LTE/BLE/GNSS connectivity that fits anywhere. Originally designed for coffee and vending machines – perfect for all kinds of industrial automation.
KNOT Embedded LTE4 is a tiny but powerful industrial LTE gateway designed for integrators, automation specialists, and IoT system builders. It fits into tight spaces, mounts directly on a DIN rail, and delivers reliable LTE Cat4 connectivity with Bluetooth and GNSS support.
Use it as a primary gateway, a backup link, or an IoT data collection node – everything is powered by RouterOS for maximum flexibility.
KNOT Embedded LTE4 is made for environments where space is limited but reliability is critical:
Smart city infrastructure (parking, sensors, metering)
Coffee and vending machine monitoring
Industrial automation cabinets
Environmental & utility monitoring
Vehicle or asset tracking with GNSS
Retail kiosks, payment terminals, digital signage
LTE backup connectivity for existing Ethernet devices
IoT gateways for BLE sensors and beacons
Whether you’re building a new system or adding LTE to an existing installation, KNOT Embedded LTE4 adapts easily. It’s easy to integrate, easy to deploy, and built to perform in harsh environments – from smart city deployments to industrial automation and mobile tracking.

- All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
- Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
- Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
