LoRa is a spread spectrum wireless technology, developed by Semtech Corporation. It has been developed to allow long distance transmission of low rate data.
The low rate data is collected by remote field sensors and actuators, and is used for Internet of Things and M2M applications. Lora uses the 868 Mhz unlicensed radio spectrum, in what is known as the ISM (Industrial, Scientific and Medical) bands to wirelessly facilitate low power, wide area data communication between the remote sensors and gateway devices, which connect to the Internet, or other network.
Lora is not suitable for every Industrial Internet Of Things IIOT application.
For example if you wanted to transmit wireless CCTV images, then Lorawan would not be suitable, due to its low rate of data transfer.
What Lora excels in however, is in transmitting small amounts of data long distances, and at low power consumption.
Low power consumption is important to wireless IIOT because some of the field sensors which record the data, may be in remote locations.
Remote locations include roads and fields, which will be time consuming and therefore expensive to get to.
By having a low power consumption rate, Lora enabled sensors do not have to have their batteries replaced very often.
Devices can be engineered to run on the same battery power supply for a few years.
