In the development of the world of the Internet of Things (IoT), a technology that offers a wide range with low power consumption or known as Low Power Wide Area (LPWA) technology, is the best choice today. One of the most popular technologies is LoRaWAN. This technology is most widely used in IoT implementation because it has advantages in the range of connectivity, low power consumption with very large network capacity and simple network management. LoRa's technology received a lot of attention in the last few years. Along with the increasing needs and complexity of problems faced in IoT market, some obstacles in the implementation of these technologies. This case identified provides an overview of LoRa technology in various implementation cases, as well as the advantages, limitations, opportunities and challenges for future research. LoRa can be considered as a good candidate in solving the complexity of the problems in the development of IoT in the next future.
