MikroTik KNOT LR8G kit
An industrial-grade IoT gateway for smart asset tracking, remote monitoring, and efficient automation – now with enhanced LoRa® reception, concurrent GPS + LTE CAT-M, and a lower price.
Smart IoT Connectivity That Just Works
The KNOT LR8G is a compact, out-of-the-box gateway for LoRa®-based networks, designed to bring affordable, reliable connectivity to even the most remote or infrastructure-light environments. It supports LTE CAT-M1 and NB2, Bluetooth 5.2, 2.4 GHz Wi-Fi, GPS, and Ethernet with PoE, making it a flexible centerpiece for any IoT deployment.
Note: CAT-M1 and NB2 mobile internet connectivity allows you to save money and remotely monitor and manage equipment without needing high-cost data plans or full LTE coverage.
Whether you're tracking high-value assets across a hospital, managing a vending machine in a shopping mall, or monitoring sensors in an agricultural field – the KNOT LR8G ties everything together and keeps everything connected.
Key Features & Upgrades
- Concurrent GPS and LTE CAT-M: Track assets in motion with precise GPS while maintaining a live LTE CAT-M1 connection. Ideal for mobile units like service vehicles, containers, or roaming field equipment.
- Versatile Powering: Choose from PoE-in, DC jack, or MicroUSB – including PoE-out on Ether2 for powering other devices.
- SMA Female Connectors for All Main Interfaces: Easy antenna setup for LTE, GPS, and LoRa®.
- Improved 868 MHz LoRa® Reception: Enhanced sensitivity for stronger signal and longer range, even in interference-heavy environments.
- Lower Price, Same Reliability: Cost-effective for large-scale deployments without sacrificing performance.
- Powered by RouterOS v7: For full control, custom scripting, and advanced routing features.
Practical Use Cases
Hospital Asset Tracking
Attach Bluetooth beacons to critical medical equipment. Install a KNOT LR8G in each storage area. As gear moves, KNOT detects nearby tags, tracks location via GPS, and sends updates over LTE CAT-M – keeping inventory up-to-date and reducing manual audits.
Cold Chain Monitoring
Use wired Modbus sensors to monitor temperature and humidity inside refrigerated containers. KNOT converts Modbus to TCP and forwards data securely via MQTT or HTTPS, using low-bandwidth LTE or NB-IoT.
Agriculture & Remote Sites
Deploy KNOT to gather soil or weather sensor data in rural fields. Its wide band support, LoRa® reception, GPS compatibility make it ideal for long-range, low-power data collection.
Industrial Automation
Bridge legacy wired sensors and actuators to the cloud. With DIN rail support and GPIO monitoring, KNOT easily integrates into industrial cabinets or manufacturing environments.
Lightweight, Powerful, Cost-Effective
At 6W consumption and a small footprint (122 × 87 × 26 mm), the KNOT LR8G is perfect for deployments where space, power, and budget are limited - but performance can't be.
KNOT: track, monitor, automate - smarter and cheaper than ever before.
