At the recent World Mobile Conference, NB-IoT became the operator of the new "Fragrant Garcinula" on the stand of the device. Due to the completion of NB-IoT (Narrowband Cellular Internet of Things) technology standardization work, NB-IOT will enter the scale of commercial phase, and is expected to have a significant impact on the development of the Internet of Things industry. Therefore, the industry is also hailed as the next Blue Ocean in the field of Internet of Things. As one of the most important exhibitors at the conference, Nokia and Shanghai Bell also set up their own NB-IoT booth at the show. Nokia and Shanghai Bell demonstrated their diversified Internet of Things (IoT) portfolio for various industries, including various applications Programs, platforms, security solutions, connectivity solutions and services. Dr. Ulrich Dropmann, Chief Technology Officer, Nokia Labs, and Head of Standardization Research The GSM band is the first choice for NB-IoT deployments As we all know, there are three kinds of wireless technologies on the Internet of Things (IoT): NB-IoT, EC-GSM and eMTC. Among them, NB-IoT technology is the most mentioned in the industry, while the other two technologies are also very important to the Internet of Things. Dr. Ulrich Dropmann, CTO of Nokia Labs and head of the department of standardization research at Nokia Labs, disclosed that at present, all three Internet of Things technologies, Nokia and Shanghai Bell, support it. He pointed out that NB-IoT, EC-GSM and eMTC, to meet the different connectivity requirements of different applications. These technologies help operators and businesses provide low-cost network connections, improve network coverage in indoor and rural areas, and significantly extend the battery life of IoT devices to support remote sensors and meters. The NB-IoT is the most talked about IoT technology.
