Recently, NB-IOT technology is hot in the field of Internet of Things. Some market participants believe that this technology has driven the hype market of the Internet of Things. I don't think so. The Internet of Things market is the coming salute of the intelligent era, and it is also the magical hardware-"Big Data-"Cloud Computing-"Intellectual Union trend again.

NB-IOT, the cellular-based Narrow Band Internet of Things. NB-IoT is an emerging technology in the IoT space that supports low-power devices in the WAN cellular data connection, also known as low-power wide area network (LPWA). It has four major advantages: long battery life (more than ten years), low cost (less than $5 per module), large capacity (single cell can support 100,000 connections), and wide coverage (covering underground). In March 2016, this technical standard was established by 3GPP. For the development of the Internet of Things standards, Huawei's advancement was the earliest. In May 2014, Huawei proposed narrowband technology NB M2M; in May 2015, NB OFDMA was formed to form NB-CIOT; in July, NB-LTE and NB-CIOT were further integrated to form NB-IOT; NB-IOT standard is expected to be 3GPP R13 appeared and was frozen in March 2016. 3GPP is a communication technology alliance organization, mainly to develop a third-generation technical specification based on the GSM core network, UTRA (FDD is W-CDMA technology, TDD is TD-CDMA technology) as the wireless interface.

It can be seen that NB-IOT is a technical strategy for traditional communication equipment vendors and operators to enter the Internet of Things. It is not the whole or the whole of the Internet of Things.

To study the Internet of Things, we must understand the most basic rules. I think the three laws of the Internet of Things are as follows:

The first law: the law of diversity and uniqueness. The Internet of Things is the Internet of Everything. Each type of object has different requirements for the Internet of Things according to its own characteristics and functions. The object itself is also very different in the choice of the best information interaction technology. Therefore, IoT technology is definitely diverse, and it is unique according to the specific functional network needs. I think carrier technology, Bluetooth, Wifi, QR code, NFC and other technologies have value in different scenarios. A certain technology is monopolistic in some scenarios. For example, carrier communication is in the power network, and two-dimensional code is in the payment scenario.

The second law: the law of capacity. The network value is proportional to the number of nodes and the amount of information. This law is derived from the Internet and also applies to the Internet of Things. In the process of IoT information interaction, its value (the value of information, the value of the device that transmits information) is highly proportional to the amount of information. The four features of NB-IOT have long battery life (more than ten years), low cost (less than $5 per module), large capacity (single cell can support 100,000 connections), wide coverage (can cover underground) and The law is conflicting, which determines that the network of NB-IOT technology may be a low-value network.

The third law: the law of value. The Internet of Things is not networked for networking. The speed, scale and quality of the specific IoT construction and development are directly proportional to the value provided by the Internet of Things. This is an important factor driving IoT operators and all parties to invest.

Regarding the subdivision of the Internet of Things, a few rough lists:

SuperMap Software (300036) is currently building a database software system for land and resources and real estate in various places. At present, some of these projects are national networking, and some are regional. However, because of the oligarchy nature of the super-map in the domestic business, when these data resources are built to generate value, the hypergraph can be further integrated and mined by its system service provider and the role of some business operators, thus generating a new business model.

Neusoft Carrier (300183), the international leader in carrier communication technology, is currently fully participating in the national grid-led smart grid and four-in-one business. In the smart grid, the user terminal is mainly upgraded to the micro-grid of the AMI architecture, and the four-in-one service is to integrate the meter readings such as water, electricity and coal. Neusoft is based on carrier technology and integrates communication as a solution. It is currently participating in the pilot of the State Grid in several provinces and cities across the country. At the same time, Neusoft is vigorously expanding its smart home and smart community business through technological innovation and channel innovation. It is worth mentioning that Neusoft, as a company in Shandong, Qingdao, has a good industrial relationship, whether it is the power network of the Shandong control panel or the home appliance town of Qingdao.

And the Thai (002402) home appliance controller core manufacturers. In this respect, it can be said that Neusoft is complementary. With its traditional advantages, Hetai plays an important role in the intelligentization of home appliances. It and the 3183 teamed up with home appliance manufacturers to better promote the smart home business.

Radio and TV Express (002152) ATM, VTM and other automatic financial terminal manufacturers. It has an important card position advantage in the financial terminal networking, which deserves attention.

New World (000997) Mobile payment terminal, QR code solution provider. At present, a closed loop of payment and marketing is gradually being formed.

Hanwei Electronics (300007) started with gas sensors and is gradually infiltrating into various aspects of water, electricity, coal and other scenarios, and has certain advantages in the construction of smart cities and safe communities.

Gold Card Share (300349) Gas Internet of Things

Suo Ling shares (002766) car entertainment and communication system

In the IoT scenario, I think smart energy, smart home/community/building, car networking (car network/charging pile/parking network), QR code (payment/ID/marketing), automatic financial terminal network has a larger potential. The research is limited, and you are welcome to suggest a segment of the Internet of Things leader. It is best to talk about the logic.
