Anonymous users2024-02-09The construction of wireless cities is a long and slow process, involving many technologies and applications, and there is no clear standard for when it will be built, but it can only be said to be an evolving construction process. In fact, Shanghai's wireless city construction has been carried out for many years, and China Mobile Shanghai has extended the concept of wireless city to the height of smart city, and linked it with a large number of life applications. Here is some preliminary information for reference:
Wireless city refers to the use of a variety of wireless access technologies to provide the entire city with wireless network access anytime, anywhere, and on demand. Industry insiders believe that the wireless city, first of all, is a multi-level, full-coverage, broadband, ubiquitous, integrated information network, so that users can switch freely according to applications and scenarios, access the best network at any time, and build a convenient, safe and rapid access to the information world for citizens, which is the basis of all digital and intelligent information applications; At the same time, the wireless city is also an information application platform that integrates the Internet, mobile Internet and the Internet of Things, through the aggregation of a large number of information content and applications, it can provide convenience for the public's shopping, travel, learning, education, health care, etc., and can provide powerful tools for the opening, sales, publicity, management and other aspects of the enterprise, and can provide useful help for the openness of government affairs, supervision, urban management, etc.
Authoritative sources believe that as the fifth public infrastructure of the city after water, electricity, gas and transportation, the wireless city is the basic platform of the modern service industry, and is an important window for the best service function, which is conducive to industrial development and is closely related to all aspects of people's lives. In Shanghai, many Shanghai citizens have used some of the wireless city services provided by Shanghai Mobile in their daily life, such as "Baobao**" kindergarten monitoring service, "Social Information Communication" community information service, "mobile medical" telemedicine service, "Digital Urban Management", "Police Tong", "CMCC WiFi" and "CMCC Edu" wireless access services covering the whole city, etc.
Especially during last year's World Expo, the full coverage of wireless networks in Shanghai brought convenience to tens of millions of visitors. Li Yue, President of China Mobile Communications Corporation, said at the "Information Industry and Digital City" sub-forum of the Shanghai World Expo Closing Summit Forum that the practice of the Shanghai World Expo shows that the construction of wireless cities has become a major trend in the global information and communication field, which is of far-reaching significance to the development of the economy and the promotion of people's livelihood. In the post-Expo era, China Mobile will comprehensively promote the construction of domestic wireless cities.

Anonymous users2024-02-08Let's start with two concepts: the Internet of Things and the wireless city. In layman's terms, the Internet of Things is to make everything "connected", and there are three things that are key:
Inductive processing terminals, transmission channels, control processing platforms. In this way, inanimate things can "sense" and "process" information, transmit it to a designated place or person through a transmission network, and in turn control and command. 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 mobile phones, computers and other wireless devices can access the network anytime and anywhere.
In fact, the foundation of a smart city is a wireless city, but it is necessary to achieve a large number of practical applications on this basis, such as a car on the road.
The following case of Shanghai Mobile in the construction of wireless city and smart city, the transformation of technology into life application in the city will be explained more clearly, because the Internet of Things coverage depends more on wireless technology through the current communication network, so the mobile Internet of Things will be more in line with the future development direction
Case 2: With the help of China Mobile Shanghai's "smart parking" system, people will be able to use their mobile phones to check whether there are vacancies in the nearby parking lots, and use their mobile phones to "visit shops and buy things" in the "virtual" of Bailian in Central China.
Case 3: Connect the sensor with a wireless gateway or wireless landline, and in case of a gas leak or other dangerous situation at home, the alarm command will be sent to your mobile phone as soon as possible. The latest application of the mobile Internet of Things, "Yiqingtong", has greatly improved the "smart" level of urban security, and has been piloted in Putuo, Minhang, Songjiang, Jiading and other places, and plans to cover the whole city in the next three years.
Including "Yiju Pass", China Mobile Shanghai has 500,000 IoT end users.
There is no need to wait until 2015, such life scenes have appeared around us, and the information tentacles of the mobile Internet are connecting the dots into a line and a surface from the line, outlining a smart city and a life full of wisdom. In the view of China Mobile Shanghai, this smart city is to create an "omnipresent" and "omnipotent" smart life with a "ubiquitous" network.
In the "Twelfth Five-Year Plan" wireless city blueprint, China Mobile Shanghai proposed to use the wireless city to help the construction of Shanghai's smart city, focusing on strengthening government, developing industry and benefiting the people, so that the "wireless city" will become a "good helper for government management", "a good platform for promoting industry informatization" and "a good tool for people's livelihood services".

If you don't have a wireless city, what's the use of a wireless SIM card? Jujubes.
The advantage of wireless charging is that you can do without restrictions, and you can charge it if you want to. And it's particularly convenient, the disadvantage is that the charge is not particularly much, and if this happens, that's the explanation. His charge is not particularly adequate.
Wireless city means that most of the city has been covered by wireless networks, as long as you have access permissions, your mobile terminal can access the Internet through wireless networks, access the corresponding network resources.
Now there are many cities that have shared motorcycles, such as Meow out of the line has been in Changsha, Nanning, Jiujiang, Chengdu, Yantai, Wenzhou and other cities for operation, the future will expand more cities in the country! You can follow it.
It is said that all the prefecture-level cities in Zhejiang already have them, such as Xuzhou, Wuxi, Suzhou, Changzhou, Zhangjiagang in Jiangsu, etc. >>>More
Wireless AP can be used as a wireless router, the wireless router has a single function, generally only for home use, and AP is a wireless access device, and the access volume can be very large, that is, it can bring a lot of machines; The wireless coverage capacity of the machine far exceeds that of home routing, which can be remotely controlled and adjusted, supports PoE network cable power supply, and some also have lightning protection modules,。。
