Product Information
KNOT LR8G kit 2.4 GHz Wireless LoRa 868MHz PoE-in & PoE-out Compact Industrial IoT Gateway
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.
- LoRa ® 868MHz
- CAT-M/NB technology
- 2.4 GHz wireless
- RS485/Modbus
- 2x 100 Mbps Ethernet ports
- PoE-in & PoE-out
- GNSS interface model MT3337V
- GPIO monitoring
- 5.2 Bluetooth version
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.
Lightweight, Powerful, Cost-Effective
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.
KNOT: track, monitor, automate – smarter and cheaper than ever before.
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
