LoRa is a wireless technology utilizing radio modulation generated by Semtech LoRa transceivers.

LoRa® is a wireless modulation technique that uses Chirp Spread Spectrum (CSS) technology. CSS encodes information using wideband linear frequency modulated chirp pulses. LoRa® can operate on the following sub-gigahertz ISM (Industrial, Scientific, and Medical) bands without requiring a license: 433 MHz, 868 MHz, and 915 MHz. These bands are reserved internationally for industrial, scientific, and medical uses.

If you need to add LoRa connectivity to your projects, Arduino® has got you covered with a range of boards, addons, and libraries.

LoRa can transmit up to 3 miles (5 kilometers) in urban areas and over 10 miles (15 kilometers) in rural areas with line of sight.

LoRa technology has become the go-to solution for connecting IoT devices due to its wide acceptance. It offers the flexibility of long-range connectivity and low-power consumption, making it suitable for various fields like industrial IoT (IIoT), smart environment monitoring, smart agriculture, smart homes and cities, smart utilities and metering, and smart supply chain and logistics. Its low-power features make it perfect for battery-operated sensors and low-power applications.
