Long-Range Low-Power End Node Solution

With the growing Internet of Things, a LoRa® technology wireless solution to address increasing demands on end-devices for long range connectivity, low-power for battery operation, and low infrastructure cost for volume deployment were now easy to acquire. LoRa technology solution mostly are ready to run out-of-the box and with the complete LoRaWAN® protocol and certifications in place, it reduces time to market and saves development costs. LoRa technology is ideal for battery-operated sensor and low power applications, including: Internet of Things  Smart agriculture  Smart city  Sensor networks  Industrial automation  Smart meters  Asset tracking  Smart home  M2M

The Origin Of LoRaWAN

LoRa (Long Range) is a proprietary low-power wide-area network modulation technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo of Grenoble, France and acquired by Semtech, the founding member of the LoRa Alliance and it is patented. 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 with low power consumption. The technology covers the physical layer, while other technologies and protocols such as LoRaWAN (Long Range Wide Area Network) cover the upper layers. It can achieve data rates between 0.3 kbit/s and 27 kbit/s depending upon the spreading factor. LoRa devices have geolocation capabilities used for trilaterating positions of devices via timestamps from gateways. Since LoRa defines the lower physical layer, the upper networking
