Prospects of LoRaWAN Technology for IoT Solution in Bangladesh

As the fastest‐growing economic country in the Asia Pacific, Bangladesh needs to be technologically advanced and adaptive in every sector to foster its development. In recent times, Internet of Things (IoT) has shown its potential for improving productivity and efficiency, thus contributing to a country’s economy. With technological advances, the need for low‐power, low‐cost, and secured IoT solutions has become prominent, especially for a developing country like Bangladesh. Long‐range wide‐area network (LoRaWAN) is an IoT solution that meets those criteria and provides exceptional long‐range coverage in addition. In this article, the possibilities of LoRaWAN technology have been analyzed from the perspective of Bangladesh. Initially, a technical review has been performed on its background, network topology, and compared with other leading technologies. Then a design architecture of the LoRaWAN’s end‐node and gateway has been presented. The article also investigates the possible deployment scenario and future scopes of LoRaWAN in Bangladesh. Finally, a LoRaWAN system has been demonstrated using two nodes in an urban scenario and experimentally evaluated data reception, received signal strength, and LoRa packet loss or delay over two different communication ranges. Based on the experimentation conducted, a maximum coverage of 1.094 km has been estimated by the log‐distance probabilistic approach.
