LoRa Frequency Bands in Australia: AU915-928 Details

lorawan frequency band australia iot network rf wireless

LoRaWAN networks rely on specific frequency bands for efficient communication. In Australia, these frequencies are governed by local regulations. The ISM band allocated for LoRa in Australia ensures compatibility with IoT applications like smart metering, agriculture, and logistics.

This guide provides an overview of the LoRa frequency bands used in Australia, their specifications, and their role in enabling long-range, low-power IoT communication. It also touches upon data rate and Tx power (i.e., EIRP). LoRaWAN frequency bands, channels, EIRP, and data rate requirements are specific to different parts of the world. Let’s examine these values for AU (Australia).

What LoRaWAN Frequency Bands are Used in Australia?

The AU915-928 band, covering 915 MHz to 928 MHz, is used in Australia for LoRaWAN systems. Channel frequencies are divided as follows:

  • Upstream: 64 channels starting at 915.2 MHz and extending to 927.8 MHz with a linear spacing of 200 KHz.
  • Upstream: 8 channels starting at 915.9 MHz and extending to 927.1 MHz with a linear spacing of 1.6 MHz.
  • Downstream: 8 channels starting at 923.3 MHz and extending to 927.5 MHz with a linear spacing of 600 KHz.

The table also mentions modulation, BW (125 KHz), channels, bit rate, and duty cycle.
