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.

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 centrepiece for any IoT deployment. CAT-M1 and NB2 mobile internet connectivity allows you to save tons of 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.

At just 6W consumption and 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.
