Abstract

LoRa (Long Range) is a low power wide area network (LPWAN) technology primarily used for the Internet of Things (IoT). LoRa is best suited for applications that deliver smaller amounts of data at low bit rates. Data can be transferred over a larger area than WiFi, Bluetooth, or ZigBee technologies. These features make LoRa an excellent option for low power sensors and actuators. For LoRa to work, license-free sub-gigahertz frequencies like 915 MHz, 868 MHz, and 433 MHz are the best. In order to acquire faster data rates than sub-gigahertz bands, it can also be operated at 2.4GHz. Different LPWAN technologies are now competing for market dominance in order to offer the huge connection needed by a future in which all objects are predicted to be connected to wireless networks and capable of communicating with one another. Here, the wireless communication link has been established between the two LoRa nodes and the output data frames are received by the LoRa gateway and routed through network servers to control the gateways using standard IP technology.
