Nokia Bell Labs cto:nb

at the recent World Mobile conference, Nb IOT has become a new hot topic on the booths of operators and equipment manufacturers. Due to the completion of the standardization of Nb IOT (narrowband cellular IOT) technology, Nb IOT will enter the stage of large-scale commercial use, and is expected to have a significant impact on the development of IOT industry. Therefore, it is also praised by the industry as the next blue ocean in the development field of IOT

as one of the most important exhibitors of the conference, Nokia and Shanghai Bell also set up their own NB IOT booth at the exhibition. Nokia and Shanghai Bell showed their diversified IOT product portfolio for various industries, including various applications, platforms, security solutions, connectivity solutions and services

GSM band is the first choice for NB IOT deployment

as we all know, there are three wireless technologies for IOT access, namely NB IOT, EC GSM and EMTC. Among them, Nb IOT technology is the most mentioned in the industry, and the other two technologies are also very important to IOT. Nokia bell Experiment 4. Dr. Ulrich dropmann, chief technology officer of the movable collet locking mechanism room and head of the standardization research department, revealed that at present, Nokia and Shanghai Bell all support these three IOT technologies. He pointed out that Nb IOT, EC GSM and EMTC can meet different connection requirements of different applications. These technologies can help operators and enterprises provide low-cost network connections, improve network coverage in indoor and rural areas, and significantly extend the battery life of IOT equipment to support remote sensors and instruments. NB IOT is the most concerned IOT technology at present

compared with traditional IOT technology, Nb IOT technology has five advantages: large capacity, wide coverage, low power consumption, low cost and high stability. In terms of capacity, the uplink capacity of Nb IOT is 50 to 100 times higher than that of 2g/3g/4g, which means that the same base station can use this technology to improve its access capacity 100 times higher than the existing wireless technology. In the era of IOT, it provides more powerful support for the explosion of the number of access hardware devices. In terms of power consumption, due to low rate and low bandwidth, the RF, PA and other requirements will be lower, and the cost of its chip will be significantly reduced. At the same time, because NB IOT can be directly deployed in GSM, UMTS and LTE networks only in the field of special steel materials, the reuse of existing base stations can also reduce the deployment cost

with regard to the spectrum layout of nb-iot technology, Dr. Ulrich dropmann believes that for the Chinese market, the deployment of narrow-band IOT on the GSM spectrum is the most convenient and low-cost from the perspective of standards and technology. Similarly, the current coverage of IOT is very good, and in the current low-frequency coverage frequency band of IOT, narrowband IOT can also be deployed. According to the situation in China, Ulrich drop1 Dr. Mann said that the GSM band is the primary choice and the best choice for NB IOT technology. However, it does not rule out that operators have different considerations

solutions help the development of IOT market

Nokia and Shanghai Bell demonstrated their comprehensive capabilities related to IOT at the 2016 world mobile communication conference, providing professional support for operators and enterprises in the rapidly developing IOT market and coping with a large number of new applications and new business models. Nokia and Shanghai Bell perfectly combine their network infrastructure with secure IOT connection, distributed cloud, and IOT platform with application and analysis functions. In addition, Nokia and Shanghai Bell IOT services will also provide powerful complements, providing relevant design, integration and customized IOT solutions

it is reported that Nokia's IOT community is designed for enterprises from all walks of life to develop new business models for IOT applications. The reasons for such failures and troubleshooting methods: (1) the push rod of the key switch is too long to cooperate. The community aims to validate new business models, help Nokia expand its IOT partner ecosystem, and conduct wireless and device certification with leading device and application manufacturers. This collaboration will accelerate the development of IOT solutions and create greater business value

overview of Nokia IOT solutions:

Nokia's IOT product portfolio provides a flexible, secure and scalable multi-user platform independent of devices to help operators and enterprise customers quickly develop, deploy and support new applications and business models

connectivity management helps operators manage the rapidly increasing number of sensor and device connections, especially SIM connections

the application platform supports operators to quickly, economically and efficiently create customized IOT applications and services

device management is designed for rapid and remote deployment of devices, sensors, meters or modules. Nokia supports all current IOT device management standards

IOT service provides professional services related to the design, integration and customization of connection management platform and application layer to meet the specific needs of different vertical industries

Nokia will provide a full set of narrowband IOT commercial products by the end of this year, which will be deployed in the network of operators. From the whole standardization process of narrow-band IOT, standardization discussion and product development are parallel. If people in the industry can reach a consensus in the field of industrial R & D and implement it in the field of productization in the process of discussing the narrowband IOT standard. Ultimately, the whole industry, end users and operators will benefit. Dr Ulrich dropmann revealed to

in addition, Dr. Ulrich dropmann also said that Nokia and Shanghai Bell have played a very important and active role in promoting the development of TD-LTE industry and technology in China. This time, Nokia, Shanghai Bell and China Mobile also won awards for their innovative solutions in Ningbo stadium. He pointed out that in areas with high user density such as stadiums, the system performance has been significantly improved, with users' downlink increased by 60% and uplink increased by 30%, which fully proves that technological innovation will improve people's quality of life and meet the needs of life. It is believed that Nokia and Shanghai Bell will bring more innovative technologies to the whole industry and end users in the 5g and LTE fields in the future, including the technological evolution of TD-LTE
