LoRa WAN SYSTEMS
LoRa is a LPWAN (Low Power Wide Area Network) radio technology that enables long range transmission for objects with modest power consumption. LoRa acts in the free sub-giga Hertz band, mainly 868 MHz (Europe) and 915 MHz (North and South America) and allows transmission in the order of 10+ kilometers. The structure of the network provide the existence of at least a LoRa gateway covering a wide area, able to manage thousands end points (meters, waste bins street lighters, parking sensors,…), collecting data from them and uploading to the Cloud. Over the LoRa physical layer enabling the long-range communication, an upper layer was developed to manage the connection between gateways and end nodes. This is the LoRaWAN standard and it’s elected as interoperability pre-requisites for an end point as for the gateways to be able to operate together even if produced by different manufacturers, that’s the starting point for an integrated IoT network including several type of devices.
