1.1 Communication & Transport

The IoT Pro protocol uses a consistent application payload structure across all connectivity options.

The underlying transport mechanism depends on the selected network bearer:

• Cellular (NB-IoT / LTE Cat-1) and Wi-Fi
  Communication is performed over UDP (User Datagram Protocol) for efficient, low-overhead data transmission.

• LoRaWAN
  Communication is performed over the LoRaWAN protocol, using standard LoRaWAN network server infrastructure.

• SIGFOX
  Communication is performed over the SIGFOX network protocol, using SIGFOX backend services.

This approach ensures that the IoT Pro payload remains standardised, regardless of the transport layer used.
