Why LoRa
LoRa is a low-power, long-range wireless technology designed for the Internet of Things. It is less affected by buildings and other obstructions than regular WiFi, with one gateway generally being able to provide coverage for a 70x70m 3-story building.
LoRa is expected to hold 75% of the IoT device market share soon. The LoRa community is expanding rapidly, with many new contributions and developments occurring every day.
Considering LoRa transmission messages are very small, around 50 bytes, less power is required than say to make a phone call or upload a photo. Using LoRa, our sensors can achieve a 5+ year battery life when pushing data once a day. Alternatives either cannot transmit the required distance, or are too costly to do so.
LoRa runs on a low radio frequency, which enables the transmission to penetrate common building obstacles such as furniture, walls, pipes and even concrete. Our LoRa Raw devices can transmit around 100m in a commercial building, which is impressive considering the weaker penetration of WiFi.
The LoRa community is very active and open, comprising of companies and individuals who are further developing LoRa and LoRaWAN. Because of this, the technology is constantly improving and there is lots of available support online and through forums. This is different from legacy, proprietary software.
