Integrated LoRaWAN Gateway

The KNOT LR8 Kit is built around a dedicated LoRaWAN gateway interface, allowing it to communicate with compatible LoRaWAN sensors and end devices.

LoRaWAN is designed for low-power, long-range IoT communication. It is particularly useful for sensors that transmit relatively small amounts of data over long distances while operating from batteries for extended periods.

The KNOT can therefore act as an aggregation point between distributed LoRaWAN sensors and an IP-based network, allowing sensor data to be transported through Ethernet, Wi-Fi or cellular connectivity.

LTE-M and NB-IoT Connectivity

The KNOT platform supports cellular IoT connectivity through its compatible LTE modem configuration. LTE-M and NB-IoT technologies are designed for low-power wide-area cellular applications and are commonly used for telemetry, asset monitoring, metering and remote sensors.

A compatible SIM card can provide cellular connectivity where wired network access is unavailable or where cellular connectivity is preferred for a remote IoT installation.

2.4GHz Wi-Fi Connectivity

The KNOT includes a built-in 2.4GHz 802.11b/g/n wireless interface. The wireless interface supports a theoretical PHY rate of up to 300Mbps.

The actual wireless throughput depends on signal conditions, interference, channel configuration, client capability and network traffic. The integrated Wi-Fi can be used for local connectivity, configuration and compatible IoT applications.

Bluetooth 5.2 for IoT Devices

The integrated Bluetooth 5.2 interface allows the KNOT to communicate with compatible Bluetooth devices and sensors.

This can be useful in IoT deployments where Bluetooth-based sensors need to be connected to a central gateway and then forwarded to a wired, wireless or cellular network.

GPS and Multi-Constellation Positioning

The KNOT provides satellite positioning support using multiple GNSS systems, including GPS, GLONASS, BeiDou and Galileo.

GNSS functionality can be useful for asset tracking, mobile equipment, remote installations and IoT applications where the geographic location of the gateway or monitored equipment needs to be determined.

Industrial Interfaces

Unlike a conventional wireless router, the KNOT provides interfaces designed for industrial and IoT deployments.

• RS485 for compatible industrial equipment and sensors.
• GPIO interfaces for digital monitoring and control applications.
• Ethernet for wired IP connectivity.
• USB for supported peripherals and expansion.
• Serial interfaces for compatible industrial applications.

These interfaces allow the KNOT to operate as an IoT gateway between physical sensors and modern IP-based networks.

Passive PoE and Power Options

The KNOT supports passive PoE-In for simplified network deployment. Depending on the configuration, compatible connected devices can also receive power through the KNOT’s passive PoE-Out functionality.

Because passive PoE does not perform automatic voltage negotiation like active IEEE PoE standards, the voltage and power requirements of the connected equipment should always be verified before connecting a device.

RouterOS v7 and Network Management

The KNOT runs MikroTik RouterOS v7 with a Level 4 license. This allows the IoT gateway to provide much more than basic sensor connectivity.

• IP routing
• Firewall and NAT
• DHCP services
• VPN connectivity
• VLAN configuration
• Wireless management
• Traffic filtering
• Network monitoring
• Cellular connection management
• Remote network administration

2× Ethernet Ports

The KNOT includes two 10/100 Mbps Ethernet ports. These ports provide wired network connectivity for industrial equipment, switches, computers and other IP devices.

The Ethernet interfaces can also be integrated into RouterOS bridges, routed networks and VLAN-based architectures depending on the deployment design.

IoT Gateway for Industrial and Remote Applications

The combination of LoRaWAN, cellular IoT, Wi-Fi, Bluetooth, Ethernet, GPS and industrial interfaces makes the KNOT suitable for applications where multiple communication technologies need to be integrated into a single gateway.

Typical deployments include:

• Smart agriculture and farm monitoring
• Industrial sensor networks
• Smart building systems
• Environmental monitoring
• Remote telemetry
• Asset monitoring
• Utility and metering applications
• Cold-chain monitoring
• Infrastructure monitoring
• Remote IoT installations
