Driven by the LoRa Alliance, LoRa technology is able to achieve a range of up to 10 miles and 10-year battery life. The technology targets low data rates and low duty-cycle applications such as energy metering, location tracking, utility infrastructure monitoring and control, smart city and agriculture. Although predominantly used for the uplink of sensor data, bidirectional communications allow real-time acknowledgement of mission-critical data and downlink control of remote actuator nodes.
The RN2903 is designed to be easy to adopt, which minimises research and development investment and speeds time-to-market. The simple ASCII-over-UART interface can be controlled by any embedded system, even down to a tiny, eight-pin PIC12 MCU and the embedded antenna matching circuits and FCC modular certification require minimal radio expertise.
