What is LoRa?

LoRaWAN is a Low Power, long distance, wireless transmission ecosystem designed for IOT. It includes the following benefits and limitations.

  • Transmission is on one of 64 channels upstream and one of eight higher bandwidth channels downstream.
  • The payload is slower than realtime audio or video and really lends itself to simple sensor update.
  • Communication is initiated by the sensor and not by the Gateway. (our deployment is Class A)
  • Distance is quite far (in the range of seven miles) but the transmission payload will scale to support the distance.
  • Transmission security is based on three keys including the IP address, Network Server and Application Server. Additional encryption is also available like AES128.
  • Provisioning can take place through the Network Server or Over the Air.
  • LoRaWAN is adopted in many counties overseas but North America is only starting the deployment process.
  • A sensor can connect to multiple gateways and the Network Server will arbitrate the strongest transmission.
