Problem 2 What are some of the more widely used IoT products? 5 points First of all, we need to understand two concepts: the Internet of Things and wireless city. In layman's terms, the Internet of Things is to make all the things are "connected", the key to have three things: sensor processing terminal, transmission channel, control processing platform. This will allow otherwise inanimate things to "sense" and "process" information, through the transmission network to the designated place or person, and in turn can be controlled and commanded. Wireless city is through the current cellular communication network, assisted by wireless hotspot (WLAN) coverage, to achieve seamless coverage in the city, all terminals, including cell phones, computers and other wireless devices can access the network anytime, anywhere. Smart city is actually the basis of the wireless city, just to realize a large number of practical applications on this basis, as if the road to have a car.
Take the following Shanghai Mobile as an example, the technology will be transformed into a city of life applications to explain the case will be a clearer understanding of this concept, due to the Internet of Things to cover more to rely on wireless technology through the current communications network, so the mobile Internet of Things will be more in line with the direction of the future development:
Case 1: Do you want to know the child in the kindergarten to be happy? Open your cell phone, click on the "baby online", the child's knitted brows and smile as far as the eye can see. "Baby Online" in Songjiang, Minhang area 4 kindergarten pilot, by the parents warm welcome, subscribe to this service of more than 500 families, the use rate of nearly 100%.
Case 2: In Putuo's Central Parkland, with China Mobile Shanghai's "smart parking" system, people will be able to use their cell phones to view nearby parking lots with or without empty spaces, and use their cell phones to shop in Central Parkland's "virtual mall". The system will allow people to use their cell phones to see if there is a parking space available in the neighborhood, and use their cell phones to store and buy in the "virtual mall" of Central Parkland.
Case three: the sensor will be connected to the wireless gateway or wireless landline, once the home gas leakage and other dangerous situations, the alarm command will be the first time sent to your phone. The latest application of mobile Internet of Things, "Yijutong", has greatly improved the level of urban security "smart", has been in Putuo, Minhang, Songjiang, Jiading and other pilot, the next three years plan to cover the city. Including the "livestrong", China Mobile Shanghai has 500,000 IoT end users.
No need to wait until 2015, such a life scene has appeared in our side, a mobile Internet of information technology tentacles, is from the point connected to the line, from the line connected to the surface, sketched out a smart city, a smart overflowing life. In the view of China Mobile Shanghai, this smart city is to "ubiquitous" network, to create "everything", "omnipotent" smart life.
In the "Twelfth Five-Year Plan" wireless city blueprint, China Mobile Shanghai Company puts forward the wireless city to help Shanghai's smart city construction, centered on the strength of the government, industry, and benefit the people, so that the "wireless city" to become a "good helper for government management". The wireless city is a good helper for government management, a good platform for promoting industry informationization, and a good tool for people's livelihood services.

The function of the perception layer is mainly to obtain information, and is responsible for collecting physical events and data that occur in the physical world, and realizing the perception and recognition of information in the external world. This includes traditional wireless sensor networks, global positioning systems, radio frequency identification, barcode readers, and so on. This layer mainly involves two main types of key technologies: sensing technology and identification technology. The sensing of sensor network mainly carries out large-scale and distributed information acquisition and state identification through various types of sensors on the material properties of objects (such as temperature, humidity, pressure, etc.), environmental state, behavioral posture and other information, which can be used in the fields of environmental monitoring, remote medical treatment, smart home and so on. Marking technology realizes the interconnection of any object in IoT by assigning a unique identification code to each object.
The network layer is mainly to complete the transmission and processing of sensory information with high reliability and high security. From the perspective of specific realization, this layer is divided into three layers from bottom to top: access network, core network and service network. ① access network: mainly to complete the network access of all kinds of equipment, emphasizing all kinds of access methods, such as the existing cellular mobile communication network, wireless local/metropolitan area network, satellite communication network, all kinds of wired networks and so on. ② core network: mainly to complete the long-distance transmission of information, currently relying on the existing Internet, telecommunications networks or television networks. With the advancement of triple play, the core network will develop towards an all-IP network. ③ business network: is the realization of the Internet of Things business capabilities and operational support capabilities of the core components.
The application layer is mainly the use of analyzed and processed sensory data, the Internet of Things technology and personal, family and industry informatization needs conjunction platform, can provide users with rich service content, greatly improving the degree of production and life intelligence, the application of a very broad prospect. Its application can be divided into monitoring type (logistics monitoring, pollution monitoring, disaster monitoring), query type (intelligent retrieval, remote meter reading), control type (intelligent transportation, smart home, street light control, remote medical care, green agriculture), scanning type (cell phone wallet, ETC) and so on.
