Abstract In this article a review has been performed on the technical background and the core supporting technologies of the narrow-band Internet of Things (NB-IoT) and the possible applications in perspective of conditions of Bangladesh. At the commencement of the paper, it introduced NB-IoT techs’ background, history of development, and standardization. Then, described the features of NB-IoT by the recitation and review of research and studies currently performed and published on NB-IoT technology, in which the paper has focused on fundamental and core technologies regarding NB-IoT, analyzed several types of performance criterions of NB-IoT and compared other types of wireless technologies based on several performance indicator factors. After that, the paper discussed intelligent and smart implementations of NB-IoT such as smart and safe houses and buildings, smart grid, smart cities, monitoring environment intelligently, intelligent and smart farming, intelligent industrial automation in perspective of Bangladesh. These discussions are intended to provide an overview of the potentiality of NB-IoT in Bangladesh, which can be helpful for researchers and readers to point out scientific problems and the scopes of future research on NB-IoT in Bangladesh.

1 Introduction IoT elaborated as the Internet of Things is a newly emerged technology based on cellular communication. Possible applications of it are becoming exigent day by day in the telecommunication sector. A technical report of Ericsson says that there are approximately 16 billion devices connected around the globe. In 2021 the count will be predicted to grow to almost 28 billion. Of which 53% will be Machine to Machine (M2M) client-level electronics devices and other than mobiles, PCs, and tabs. According to Qualcomm, the number of interconnected devices will be increased from 2.2 billion in 2015 to around 3.4 billion in 2020 and more than 5 billion in 2025 approximately. Thereby, high speed access on the internet is required, because the vital operators in mobile network evolution were human-centric. The IoT technology and it’s robust application objects have several characteristics based on the terms of latency requirement, traffic pattern and deployment density. That is why several wireless technologies have been designed and implemented in order to facilitate several segments of IoT connectivity support [1]. On the basis of rate of data transmission, communication of IoT is categorized into two: (1) high
