What is LoRaWAN ?

LoRaWAN is a low-power wide-area networking (LPWAN) protocol designed for use with low-power IoT devices. It is based on the Long Range (LoRa) radio technology developed by Semtech, and is intended to provide long-range, low-power connectivity for devices such as sensors and actuators in the Internet of Things (IoT).

Sensing Network is plug and play LoRaWAN

LoRaWAN is a very complete protocol but could be sometimes complex. We designed Sensing Network to be a plug and play LoRaWAN network server :

  • LoRaWAN gateways register automatically,
  • Device decoding
  • Sensor data vizualisation

When your data come in, you can share it to your favorite applications or protocol using many integrations.

LoRaWAN device connectivity

AWS IoT Core for LoRaWAN supports all devices that comply to the 1.0.x or 1.1 LoRaWAN specifications standardized by LoRa Alliance. Before a LoRaWAN device can start sending data to a network server, a process called activation or join procedure is required. IoT Core for LoRaWAN supports both of the approved ways of device activation as specified by LoRa Alliance: OTAA (Over the air activation) and ABP (Activation by personalization).

LoRaWAN devices can send uplink (device-to-cloud) messages at any time. However, listening for downlinks (cloud-to-device) messages can consume battery capacity and reduce a battery’s lifetime. To support a variety of application requirements with different trade-offs between listening behavior and battery consumption, the LoRaWAN protocol supports three classes of devices (A, B, C). IoT Core for LoRaWAN supports all the three classes. Lastly, IoT Core for LoRaWAN also supports device profiles so that you can define device data rates, channels, and other settings which will be used when the IoT Core for LoRaWAN network server communicates with the device.

Supported frequency bands

AWS IoT Core for LoRaWAN customers can use US902-928, EU863-870, AS923-1 or AU915 frequency bands to connect LoRaWAN gateways and devices that are physically present in countries that support the frequency ranges and characteristics of these respective bands. US902-928 and EU863-870 bands are commonly used in the North America and European regions respectively. AS923-1 is commonly used in Australia, New Zealand, Japan, Singapore, and Taiwan among other countries. AU915 is commonly used in Argentina, Chile, and other South American countries. The LoRa Alliance publishes the LoRa Alliance Regional Parameters to help companies decide which frequency bands to use in their region or country. The frequency band implementation for AWS IoT Core for LoRaWAN follows the recommendations in this regional parameters specification document. These regional parameters are grouped into a set of radio parameters along with a frequency allocation that is adapted to the Industrial, Scientific, and Medical (ISM) Band. We recommend customers work with their compliance teams or consult with local regulatory bodies to ensure they meet any applicable regulatory requirements.

LoRaWAN gateway connectivity

Gateways serve as a bridge and carry LoRaWAN device data to and from a network server, usually over high-bandwidth networks like Wi-fi, Ethernet, or Cellular. The LoRa Basics Station—an open-source software maintained by Semtech Corporation and distributed via their GitHub repository—running on your gateway is a prerequisite for connecting to Sensing Network. Most gateway manufacturer provide compatible gateways like :

  • Kerlink
  • Tektelic
  • Advantech
  • Milesight
  • Dragino
  • Rakwireless
  • Browan
  • Laird Connectiviy
