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.

Ethernet test results
- 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
The device has an operating system preinstalled and licensed. No separate purchase is necessary and the product is ready to use. The device includes free software updates for the life of the product or a minimum of 5 years starting from date of purchase..
