Australia (and New Zealand)

Australia uses the 915 MHz to 928 MHz wireless network frequency band and thus manufacturers of devices using the Microchip LoRaWAN module RN-2903A must load the correct firmware from Microchip to make the devices function properly.

In Australia, we use the 915-928 MHz frequency range with a maximum Equivelant Radiated Isotropic Power (EIRP) of 1 watt. ... Although the US also uses 915 MHz, the actual band is wider than ours (902-928 MHz) and it is illegal to use the lower part of the band in Australia.

LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe), 915 MHz (Australia and North America), 865 MHz to 867 MHz (India) and 923 MHz (Asia). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption.

In a typical LoRaWAN network, range depends on numerous factors—indoor/outdoor gateways, payload of the message, antenna used, etc. On average, in an urban environment with an outdoor gateway, you can expect up to 2- to 3-km-wide coverage, while in the rural areas it can reach beyond 5 to 7 km.

LoRaWAN implements a star network topology: end nodes transmit data to a central server via one or multiple gateways. All devices in a LoRaWAN network are asynchronous and transmit data only when data is available. To increase the security and range of a LoRaWAN network, you can deploy it as a mesh network.

LoRaWAN supports bi-directional communication. A single LoRaWAN Gateway can accommodate 1,000s of devices or nodes, multiple Gateways provide resilience to smart solutions.

The story of LoRa began in 2009, when two friends in France aimed at developing a long range, low power modulation technology. Despite encountering resistance, as with most disruptive technologies, Nicolas Sornin and Olivier Seller continued dedicating their time to turn the idea into a reality.
