NB-IoT (Narrowband Internet of Things), with its low power consumption, low cost, and wide coverage, can meet the demand for low energy consumption devices that rely on batteries to connect and send small amounts of information, and is increasingly used in the IoT industry. With the increase of indoor coverage of this new technology, reduction of device cost, and reduction of energy consumption, the smart home industry has also explored the application of NB-IoT technology. On July 27, Haier took the lead in “new things, new Scenario and New Ecology - Smart Home Industry NB-IoT Application Promotion Summit Forum jointly formulated the first smart home NB-IoT standard and released the NB-IHome Solution, the first NB-IoT solution in the smart home industry. The NB-IoT commercial solution that covers 3 sets of smart home appliances, smart communities, and commercial appliances will be on-site. Please see the reporter's interview with Fan Jiqing, director of U+ development at Haier, to find out how NB-IoT is integrated with smart homes. First, technical background Director Fan Jiqing first introduced the development of NB-IoT technology. He said that wireless communication has gained rapid development in recent years due to its convenient and congenital advantages. It has been widely used not only in commerce but also in military applications. As the content of services provided by the Internet has become more and more abundant, the information processing capabilities of communication terminals have also been strengthened, and services such as mobile office and mobile phone shopping have finally turned from fantasy to reality. Smart home appliances have also entered the homes of ordinary people. Among a variety of wireless communication technologies, technologies such as Wi-Fi, Bluetooth, Zigbee, and cellular mobile communication technologies are widely used in smart home smart home appliances. With more and more intelligent requirements, the number of connected devices is increasing, and the demand is also diversifying. At present, high-rate 3G and 4G communication systems can be used to meet the requirements. Medium-rate use of 2G communication can be satisfied, and low-rate low-power cellular application standard protocols are not yet complete. 4G, 3G, and 2G cannot meet the requirements of low power consumption, low cost, wide coverage, and large capacity. Lora, Sigfox, WiFi, Bluetooth, and ZigBee have defects in information security, mobility, coverage, and capacity. In order to meet the needs of the development of the Internet of Things, the narrow-band Internet of Things communication standards will follow. A comparison of advantages and disadvantages of common wireless communication technologies for smart home appliances, see the table below Second, the challenges facing the smart home industry in the development process At present, China's smart home market has a certain scale, but in the eyes of most ordinary consumers, the convenience brought by smart homes still belongs to the "icing on the cake." Director Fan Jiqing summed up the challenges faced by the current development of the smart home industry. He believes that it mainly consists of four aspects. (a) Operational convenience The purpose of smart home is to make people enjoy life and make life simpler. However, due to the technical characteristics, most smart home appliances, smart home networking, binding, use have a certain degree of difficulty. It was originally intended to be a more convenient and comfortable life, but the complicated operation made it difficult to use and severely affected the user experience. How to make the operation simpler and the function more acceptable to the user and dependent on it is the first challenge facing the industry. (II) Network capacity and signal coverage The home environment is very different. When the number of smart devices reaches a certain level, the communication between them will be affected, which will affect the normal use of the equipment; the network coverage of large houses such as duplexes or villas is a challenge that the smart home industry must face. It is difficult to network and/or communicate with water heaters, washing machines, etc. in the corners of wireless networks such as balconies and bathrooms. (c) security risks Network security is the face of the communications industry, and smart homes face the same problem. How to balance trade-offs and security is a problem that every manufacturer needs to face. (D) The standard is not uniform As the standard system is not mature, different brands of smart home appliances can not identify each other and communicate with each other. The Smart Home Appliance Smart Home is a device in the user's home. It is an APP in the user's hands and is behind a complex cloud platform service system. The design and development of smart home appliances is huge and it is difficult to achieve results in a short time. Therefore, it is a huge challenge for some small and medium-sized enterprises. Designing smart home appliances has a large investment, long cycle, and many problems. Director Fan Jiqing believes that how to face challenges, overcome difficulties, and design smart home appliances that are simple and easy to use, is a common issue facing the entire industry. Third, NB-IoT solution - NB-UHomeKit The emergence of NB-IoT technical standards provides a very good solution for low-rate, low-power, wide-area network applications and is a good complement to current device access technologies. Based on the technical features of NB-IoT, Haier U+ has designed and completed the NB-IoT integrated access solution, NB-UHomeKit, for years to come. Director Fan gave a detailed introduction to Haier's NB-UhomeKit open source application solution. He mentioned that NB-UhomeKit is a solution of Haier U+ smart life platform for accessing U+ platforms using NB-IoT technology, and implementing smart home appliances and home design applications. Agreement standards. NB-UhomeKit consists of: device-side SDK, client SDK, and M2M access gateway; NB-UhomeKit system framework as shown below: The NB-UhomeKit technology advantage includes the following five points: 1) Dedicated compression algorithm: Solve the contradiction between the small NB-IoT technology traffic and the demand for smart home big data; 2) Dedicated data acquisition algorithm: Solve the contradiction between the low rate of NB-IoT technology and the real-time requirements of smart homes; 3) Standard protocol: solve the problem of interconnection and intercommunication; 4) National Security Standards: Solving the conflict between security requirements and ease of use; 5) Standard Development Kit: Reduce development investment, shorten development cycle, and shorten time to market. Fourth, solution examples: Director Fan also introduced Haier's practical application cases on the solution. He said that after the NB-IoT standard freeze in June 2016, Haier actively launched technical communication and strategy with Huawei, Qualcomm, Telecom, Mobile, China Unicom and other companies.
