In the past few years, communication technology has been the most concerned topic in the Internet of Things industry. Whether it is the current hot LPWAN technology or an evolved version of 5G or existing technologies such as Bluetooth, wifi, and Zigbee, it can attract the attention of the entire industry. There are several reasons why technology is so important:
On the one hand, it is at the core of the Internet of Things (IoT) industry, and it is irreplaceable. It also plays a key role in linking up and down. It can connect sensors and other products upwards, and can dock downstream to end products and industrial applications. Networking business is a very important breakthrough.
On the other hand, communication technology as a basic technology is very important for IoT products and solutions. The homogenization of current hardware product functions is a very common phenomenon. For example, wristband watches and other products have similar functions in the market, but if they can improve on communication technologies, they can support such products. Rich features.

The Value of Communication Technology for Internet of Things
The application of Internet of Things is very fragmented. Communication technology as a basic technology also needs to be optimized to meet the needs of the Internet of Things. In the following, we analyze the value of the communication technologies that are currently important in IoT applications.
Meter reading
Remote meter reading is a popular Internet of Things application. Especially in today’s society, energy and resources are more and more important, so intelligent management of meters, meters, gas meters, etc. is used to achieve energy-saving and efficient use. The purpose of resources makes more sense.
The traditional method of meter reading faces several problems. First, residents are very fragmented. They need to invest a great deal of manpower to perform on-site meter reading. Second, households have a large degree of disturbances caused by meter reading and cause inconvenience to residents' lives. Therefore, the remote intelligent management of meters through the Internet of Things technology has high economic and social benefits.
Currently, the low-power wide area network technologies represented by NB-IoT and LoRa are very suitable for the meter reading field. If the operator base station covers a dense area, the NB-IoT can be used to make appropriate connections for operators. The application of LoRa+NB-IoT in the areas where the network coverage signal is not so good can better meet the application requirements. In addition, some companies in the market use the Zigbee+NB-IoT and wired+wireless solutions according to the actual needs of the project party. The corresponding application.
At present, most of the communication module manufacturers in China are involved in meter-reading-related services, among which NB-IoT module manufacturers such as China Mobile Communications, Xinxuntong, and Fangfang Technology all regard meter reading as an important business direction. Xinda, Huaaotong, Anmetong, and Hangzhou Luowan are also deeply involved in the application of LoRa in meter reading.
Security
Security is a major application market for the Internet of Things, because security is always a basic need of people. In the Internet of Things market, the most important areas of security are video surveillance and smoke alarm monitoring.
Video security Because of the large amount of data to be collected and the low latency, most of the current video surveillance in the city uses a wired connection. For remote areas and mobile object monitoring, 4G and other wireless technologies are required. In the fire alarm application market, there are great differences in application requirements. In this field, communication technologies need to have requirements such as long transmission distance, low power consumption, and stable connection. Therefore, technologies such as NB-IoT and LoRa are very suitable.
In the field of security, LongShangTech, XinXinTong, Shanghai PiYuan, BoDa GuangTong, ShengZhe Technology, Delusion Intelligence and other companies have relatively rich products and complete solutions. In addition, the three major domestic operators are also active. The expansion of this application market, driven by operators, security applications are rapidly landing.
Smart City
The smart city is a major infrastructure construction that the country has invested heavily in recent years. Its construction requires the use of various IoT products and technologies. Therefore, the smart city is currently the most important application market for the Internet of Things.
There are many types of projects covered by smart cities, and there are differences in the requirements of each type of application. Therefore, the environmental differences faced by various types of nodes in smart cities are relatively large. For example, the comparison of the physical environment of street lighting, trash cans, and shared bicycles is quite different. Ideal, so the more important for network requirements is to focus on lower power consumption, larger connection indicators, NB-IoT, eMTC and other operators of the network is very suitable for these application scenarios, while the parking lot, basement, covers and other scenes are It puts forward higher requirements for the penetration of communication networks, and can use LoRa or LoRa+NB-IoT combined solutions according to the actual needs of the project. Of course, if it is necessary to add some positioning and management functions, RFID, Bluetooth, etc. are needed. Technology is combined with LPWAN transmission technology.
In the field of smart cities, Huawei, ZTE, MG Smart, Xiamen Jun, Shanghai Mobile, Zero Smart, and many other communications companies have relatively rich application cases.
Car networking
Because of its high added value, high user acceptance, and high market penetration rate, automobiles have always been a very important application area for electronic information products. The greatest role of IoT communication functions for automobiles is reflected in three aspects. First, remote assets are used. Management, the second is the internal video surveillance of public transport, the third is to increase the functionality of the car entertainment system.
There are also great differences in the communication technology solutions that need to be used at different levels of car networking. If only asset management of vehicles is adopted, it is more appropriate to adopt GPS+GSM or GPS+NB-IoT solutions. If video monitoring is required, LTE networks are required. The car entertainment system requires LTE networks and future 5G communication technologies.
In the field of car networking, it is almost a challenge for all communication technology companies. Among them, high-growth things, core news, U-blox, Telit, Shenzhen Hongdian and other telecommunication companies all regard it as the main business direction.
Industrial area
The huge market volume in the industrial field is also a very important application area for the Internet of Things. The Internet of Things in the industrial field is mainly reflected in three aspects. First, it monitors the machinery and equipment inside the factory, and secondly, it manages the plant operators. The third is to monitor the factory environment.
The more mature monitoring method for industrial equipment is the field bus + wireless transmission method, and the wireless method will be used separately according to the specific needs of the project. The management of the personnel will be managed by means of GPS, RFID, video surveillance, etc. The environment mainly collects information such as temperature and humidity, smoke, etc. Therefore, it is appropriate to adopt LPWAN technology for transmission.
In general, the application scenario of the factory is relatively complex, basically covering all the application scenarios of the IoT communication technology. There are many communication companies in the field, such as People Networking, Lubangtong, Shanghai Yiyuan, and Fangfang Technology. And experience.
Not only communications, IOTE is a concentrated display of the entire industry chain of the Internet of Things It is understood that the IOTE2018 exhibition area reached 52,500 square meters, is expected to gather 800+ Internet of Things well-known brands from around the world, exhibiting more than 10,000 + Internet of Things latest products.
