What is LoRaWAN?

The LoRa Alliance describes LoRaWAN as “a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.”

When selecting a connectivity technology for your IoT solution, please consider the following characteristics of the LoRaWAN technology:

  • Long range : 10 miles in line of sight, 1-3 miles in urban areas, deep indoor coverage
  • Long battery duration : a battery can last up to 10 years without replacement. However, please note that long battery duration will require increased downlink latency configuration for your devices (i.e. operating devices in Class A or Class B mode).
  • Low cost for sensors and maintenance.
  • License free spectrum, however region-specific regulations apply: for example, duty cycle regulations in EU define the maximum air time for a LoRaWAN device.
  • Limited payload: 51 bytes to 241 bytes (depending on data rate).
  • Limited data rate : 0,3 Kbit/s – 27 Kbit/s data rate, 222 maximal payload size.

Detailed understanding of LoRaWAN architecture is not required to complete this workshop or to use AWS IoT Core for LoRaWAN. However, if you are curious to learn more about an architecture of LoRaWAN networks, you will find details section “LoRaWAN Architrecture”
