MikroTik KNOT LR8 kit

The KNOT LR8 kit is a complete universal device with a wide range of connection options and support for protocols or interfaces. It is an IoT Gateway for LoRa technology for maximum versatility and efficiency. The device uses Narrow Band and CAT-M technologies, which, due to the very low monthly price (compared to LTE) and low bandwidth usage, are supported by countless mobile operators around the world including the Czech Republic. This kit includes a pre-installed UDP packet router for any public or private LoRa (868 or 915 MHz) servers.

• LoRa support (868 or 915 MHz) - SMA female connector
• GPS support (GPS, GLONASS, BeiDou, Galileo) - SMA female connector
• Support for Narrow Band and LTE Cat M1 technology - SMA female connector
• Integrated Wi-Fi (802.11b/g/n)
• 2x RJ-45 10/100 Mbps (1x PoE IN, 1x PoE out)
• Built-in Bluetooth 5.2 connection (2 dBi integrated antenna)
• RouterOS operating system with L4 license
• SIM card slot (Nano SIM)
• Extra RS-485/Modbus and GPIO interface
• Wide operating temperature -40 to +70 °C
• Wide range of power supply: DC connector, PoE, Micro USB

LoRa is one of the wireless network protocols used in the world of Internet of Things - IoT (Internet of Things)

LoRaWAN (Long Range Wide Area Network) is another low-power wireless network protocol designed for low-cost and secure two-way communication in the Internet of Things. It uses a band up to 1 GHz and the transfer speed is then from 0.3 kb/s to 50 kb/s. Communication between end elements and gateways is spread over different frequency bands and transmission rates. The choice of data transfer rate is a compromise between communication range and message length. Individual communication streams with different transmission rates do not interfere with each other (due to spread spectrum technology) and create a set of "virtual" channels to increase gateway capacity. To maximize end device battery life and overall network capacity, the LoRaWAN network server manages the baud rate and RF output for each end device individually, through an Adaptive Data Rate (ADR) system

LoRaWAN distinguishes several classes of devices

• Class A - end devices support two-way communication (each uplink is followed by two windows for receiving data
• Class B - apart from the "forced" downlink of class A, devices of this class open extraordinary reception windows at set times
• Class C - receiving windows are open almost continuously and close only when transmitting
