LoRa Wireless Gateway Knowledge Base
LoRa Wireless Gateway Basic TheoryWide area network end nodes are Internet of Things (IoT) devices that operate on low power, provide long-range connectivity, and handle high amounts of traffic with less infrastructure than standard wireless networks. The LoRa gateways used for this technology can handle millions of nodes, providing a faster and cheaper alternative for secure communications.
Wide Area Network End Nodes Provide Long-Range ConnectivityLoRa wireless gateways are standalone low power wireless sensors with GPS, GNSS, and Galileo positioning. The LoRa wireless gateways provide long-range connectivity and can be logged into the network of LoRa service providers or places at free will for local and private coverage.
Low Power Wide Area Networks (LPWAN) offer long-distance wireless service up to 3km (1.86 miles) indoors or in urban areas, and up to 25 km (15.53 miles) outdoors or in rural areas. The LoRa gateways used to connect to these networks offer bi-directional communication with end-to-end encryption from the network to the device for secure data transmission and communication.
LoRa Wireless Gateway Basic Operating Principles:The Lora wireless gateway uses low power wide area networks to transmit data at high speeds. Our gateways connect to any analog sensor from 5V-24V and any I2C, SDI-12, or UART serial sensor.
Basic operation is as follows:
- A wide area network end node transmits data to a LoRa wireless gateway (868 MHz in Europe or 915 MHz in the U.S.)
- The gateway connects to the internet and propagates data to the network
- A LoRa application eventually receives the data from the LoRa wireless gateway
- The LoRa application “decides” whether or which data to respond to the wide area network end node
- The LoRa application provides sensor data for visualization with any web application
Power Management for LoRa Wireless GatewaysThe elobau LoRa end node provides power to the sensor. Voltages can be set in hardware in the 3,1V-24V range, though current draw is restricted to 40mA @>12V or 50mA @<12V. Power management options include battery power or Lilon/solar panel operation:
- Battery sets last for more than one year when operated every 20 minutes or up to 30 weeks when operated every 10 minutes.
- Lilon/solar panel operation provides full operation without attention for years, depending on sun radiation coverage.
Wide Area Network End Node Sensor Input OptionsThe voltage analog input is 0-5V with 3mV resolution, though 10V input also works well. All four LoRa wireless gateway connectors can be populated with sensors, allowing you to mix and match digital and analog signal inputs with any of the following options:
- 1x SDI-12 (serial single wire 1200 Baud)
- 1x analog @5V supply
- 2x analog @3,1V-24V supply, output signal 0-5V or 0-10V
- 2x I2C (serial) @ 3,1V supply
- 1x serial UART @ 3,1V supply (or must share higher supply with other sensors)
