The first two years, on the trend of the technology industry, there is such a summary: cloud move wisdom, that is, cloud computing, Internet of things, mobile Internet, big data, smart city. In 2016, the cloud of wisdom to become Dazhi cloud, that is, big data, intelligent, mobile Internet, cloud computing. Whether it is the Internet of things or smart city, are replaced by a new trend: intelligent. A few years ago, the development of the Internet of Things and smart cities was far less optimistic despite the conceptual fire. Its fundamental, although the application of big data, cloud computing and mobile Internet has been very in-depth, but lack of intelligence, smart city Ye Hao, the Internet of Things it is difficult to really universal open. Here to speak of intelligent, both the meaning of artificial intelligence, also have all kinds of traditional devices, terminals have become more intelligent meaning. Once all the items have become intelligent, their connection to each other and the exchange of data has become more successful. Therefore, from this point of view, the Internet of Things will still be in a prosperous stage in 2017. This is not to say that the Internet of things is no longer fiery. On the contrary, both China and other countries in the world have come to realize the industrial opportunities brought by the new round of development of the Internet of Things and even regard it as a new round of the world's economy and technology New impetus to development. China Information and Communication Research Institute recently released "Internet of Things White Paper" also pointed out that the current global Internet of Things has entered a wave of new round of development driven by the traditional industries and large-scale consumer market. First, the intelligent upgrading of traditional industries such as industry and manufacturing has become an important turning point in promoting breakthroughs in innovation in the Internet of Things. Another huge impetus has been the rise of large-scale consumer markets to speed up the promotion of the Internet of Things. To some extent, some representative areas in the Internet of Things have begun to emerge, such as consumer service robots, VR devices, smart wearable devices, etc. They actually belong to the category of Internet of Things. From the hot development of these industries, Internet of Things has entered a phase of rapid development. However, if the Internet of Things and the Internet as a contrast, the Internet of things to achieve as much as the popularity of the Internet, obviously still need to cross the threshold. Technical standards are a big hurdle. Compared with the Internet TCP / IP protocol, the Internet of Things connection technology can be divided into two categories: one is authorized WAN wide band technology to 3GPP defined NB-IoT, LTE evolution technology eMTC as the representative; the other is unauthorized Band wide area network technology, including LoRa, PRMA, Sigfox and other technologies. Insiders predict that in 2017 is expected to be NB-IOT (narrowband Internet of Things) commercial first year, the Internet of Things is expected to be officially large-scale applications. On the company front, China Mobile has said it will strive to commercialize NB-IOT in 2017. China Unicom plans to promote the commercial deployment of NB-IOTs in key cities by the end of 2016 to the beginning of 2017 and will start to push forward the commercial deployment nationwide in 2018. China Telecom is expected to begin commercialization of NB-IOT technology in 2017. However, some operators, such as Comcast in the United States, SK telecom in South Korea and Tata Communications in India, have built networks based on the more established LoRa technology and rapidly built up new network capabilities. This is quite similar to the standard dispute in the field of mobile communications. Whether it is 3G or 4G, the standards used in various countries are not exactly the same, but the differences are gradually decreasing. Nowadays, the commercialization of 5G is also gradually coming. Many people in the industry Also said that the future 5G and the Internet of Things is expected to come together. However, the development and progress of these technologies are driving the rapid development of the Internet of Things. However, they also take time. In the meantime, giants who focus on different technical standards and fields are beginning to divide new camps and form different ecosystems. Some IoT technologies in different industries have begun to enter the test phase of the water, but the era of emerging Internet business model is still in the exploratory stage. Not only that, IoT security also makes a lot of people worried. Forrester believes that the recent 1,600 DDoS attacks in the United States are just the tip of the iceberg, which will threaten the world if more connected devices are involved. This attack confirmed the fragility of IoT devices under huge distributed denial of service attacks (DDoS). There are indications that countless IoT devices including cameras, smart home and other daily electrical equipment may be hijacked by malicious software to attack the server. Until new breakthroughs are made on technical standards, business models and security issues, the development of the Internet of Things will still be on the eve of an outbreak. Hopefully, 2017 can make a breakthrough.
