The Internet of Things (IoT) enables devices to connect, interact and to send and receive data from each other. The main purpose of any IoT solution is to get data from the field to the cloud where analysis of
the data generates the desired data for the application. New radio communication wireless technology for Low power and Long range connectivity has emerged as Low Power Wide Area Network (LPWAN), with the rapid growth of the IoT market LPWAN have become a popular radio communication technology for IoT products. At the highest level, LPWAN can be split between unlicensed spectrum technologies and licensed spectrum technologies. Unlicensed LPWAN technologies (Sigfox, LoRa, Ingenu, WE-ProWare) and licensed cellular LPWAN (LTE-M, NB-IoT) technologies are available in market. Licensed spectrum cellular LPWAN technologies have multiple advantages over unlicensed spectrum technologies such as global coverage, quality of service and security.There are a range of applications (Industry 4.0, Transport and Logistics, Smart Cities, Smart Home/ Buildings, agriculture, retail, health, consumer, home appliance etc.) where cellular based connectivity could be used. Cellular solutions have several challenges e.g. certification and compliance processes (regulatory certification, industry specific certifications, mobile operator specific certifications). These certifications are involved on Chipset, Module and IoT-device level. Another challenge in considering cellular connectivity is selection of a network operator for data, SMS and Voice services based on coverage and roaming in the countries where IoT devices will be deployed. This presentation will include requirements of LPWAN technologies, application of LPWAN, as well as comprehensive study of LTE-M, NB-IoT cellular technologies, and it’s advantages. On top this paper will cover certification and compliance processes for modules, and IoT-devices. In addition, this session will provide information about SIM or eSIM.
