LoRa Spread-Spectrum Technology
LoRa® is a patented digital wireless data communication IoT technology created for wireless, battery-operated devices. Using lower frequencies than 2.4 or 5.8 GHz LoRa® have better range.
LoRa® stands for Long Range and it is a technology that uses unlicensed spectrum below 1 GHz along with a form of direct sequence Chirp spread spectrum modulation that provides signal detection below the noise level. As a result, this technology is able to use extremely low transmit power levels and can fulfil many of the requirements for long battery life.
Chirp spread spectrum has been used in military and space communication for decades due to the long communication distances that can be achieved and robustness to interference. Still, LoRa® is the first low cost implementation for commercial usage.
