In this era of industrialization, air pollution is constantly increasing due to high vehicle mobility and factors like manufactures emissions. A healthy natural environment is vitally important for all eco-systems. Nowadays, cities all over the globe are transforming into smart cities. One of the smart city requirements is ensuring clean air in its premises. Therefore, a scalable and cost-effective air monitoring system is necessary to monitor and control air pollution for smart city deployment. LoRa is a new age low-power wide-area network technology, which is very efficient for air pollution monitoring. Implementation of LoRa technology along with sensors and gateways can offer a wide range of services for natural environment monitoring to ensure public health protection. This paper reviews on LoRaWAN Technology and its application on air quality (AQ) monitoring systems.
