NB-IoT brings three opportunities to the consumer Internet of Things

In the past ten years, a large number of enterprises have explored in the field of consumer Internet of Things. For consumer Internet of Things terminals, most of them use short-distance communication. In the past two years, there has been a trend to replace short-range communication with wide-area communication in some sub-areas, and sensor manufacturers are constantly developing sensors that support wide-area communication such as NB-IoT and LoRa. As far as the characteristics of NB-IoT and some landing cases are concerned, this technology has brought three opportunities to the consumer Internet of Things.


NB-IoT

 
1. Simplify the connection and improve the user experience.

A large number of consumer Internet of things products have a special mobile phone APP that can be remotely monitored and manipulated. However, because the terminal uses a short-distance connection, the terminal data must first be concentrated on various local hub devices, and then connected to the operator through various means. The network thus enables data uploading.
 
The relevant person in charge of China Telecom Internet of Things Company used a smart home terminal as an example. If a wireless solution such as WiFi or Zigbee is used in the short-distance connection, the terminal data needs to pass through the relay, gateway, and Various intermediate devices such as routing and fiber cats are hopped to the carrier network and finally transmitted to the smart home platform for data processing. However, with the cellular network solution, the smart home terminal only needs one hop to pass the carrier network. Direct access to the smart home platform.
 
Compared with single-hop, multi-hop and non-hop bring more than just the reduction of intermediate devices, which reduces the complexity of deployment and the improvement of user experience. The smart home terminal must be configured with an intermediate device such as a mobile phone, a router, or a conversion gateway to implement the connection. For many home users, configuring the network connection for the smart home terminal is very difficult and requires professional configuration. With the NB-IoT connection method, the terminal is connected to the carrier network after being powered on, and the network is as simple as the mobile phone is turned on. All the configurations behind it do not require user hands. Because of the configuration problem, the user experience is very poor, and the consumer product is more focused on the experience, it will certainly not become popular.

2. Improve the effectiveness of networking and data

According to a report released by market research company GfK last year, the proportion of intelligent household appliances such as air conditioners, refrigerators, and washing machines rose rapidly from less than 5% in 2015 to 30% at the end of 2017, which means that 30% of newly sold home appliances have configured communication modules. Intelligent devices such as APP. Various home appliance manufacturers have standardized the intelligence of many products, and this proportion is expected to continue to rise rapidly.

However, before the sale of a large number of home appliances embedded in the WiFi module, the networking rate is very low. Many people who do smart home appliances have hinted that less than 5% of the smart home appliances and other intelligent hardware products embedded in the WiFi module are formed. Effective connection. Although the cost of the WiFi module and its intelligent solution is very low, most users are not connected and opened, which makes this solution useless and wastes the investment of home appliance manufacturers. From another point of view, home appliance manufacturers hope to achieve product lifecycle management through connectivity, but the effective connection ratio is very low, and can not collect valid data, this purpose can not be achieved.
 
The effective connection formed by the wide area network is much higher than that of the local area network. In some scenarios, even more than 90% of the effective connections can be achieved. Therefore, many manufacturers have begun to consider replacing the WiFi module with the WAN module. After adopting the NB-IoT, the network connection rate is high because the complicated configuration is not required, and the manufacturer can conveniently obtain the home appliance related sensing data. Similarly, if other consumer-grade IoT products can form the same scenario, it may also enable the replacement of WiFi with NB-IoT.
 
3. Support for some new business models
 
Many of the NB-IoT consumer products that have been successfully implemented have provided powerful support for the formation of new business models for B2B2C in related industries. When the business model closed loop can be formed, the NB-IoT consumer-grade application will naturally come to the fore.

Take Haier's sea-rental model promoted by local governments as an example. This model is to install air-conditioning, washing machines, and rental services for college students' dormitory free of charge. The return on investment is achieved by collecting usage fees. Previously, relevant operators have started leasing services for unconnected home appliances, and found various kinds of collection and refund workloads and disputes, as well as various operations of stealing home appliances, resulting in high operating costs; after that, after networking via WiFi, There are still many problems before. When the NB-IoT air conditioner and washing machine are applied, it is easy to carry out remote monitoring and operation, and the use of online payment. The problems of various high operating costs have been solved, thus supporting a typical B2B2C win-win business model.
 

In recent years, personnel tracking in various events, home user pet tracking, and shared smart devices in various public places have a new business model under the blessing of NB-IoT. Terminals and application entities need to participate more in NB-IoT's various product development, commercial demonstration, and marketing, and widely mobilize the enthusiasm of traditional consumer manufacturers and industry organizations to promote their popularity among consumers.
