What are Wireless City and 3G? There's a lot of conflict

Wireless city is to use high-speed broadband wireless technology to cover urban administrative areas, provide the public with services to obtain information using wireless terminals or wireless technology, and provide anytime, anywhere access and faster wireless networks, thereby enabling High-speed new services and new functions that cannot be used on the existing second-generation mobile communication network and will not be effective on the future third-generation mobile communication network have been developed, such as watching TV, playing online games, and mobile video on mobile phones. Chat, use your mobile phone to hold or participate in video conferences at any time, home digital network, wireless transmission of large files such as documents and photos, wireless network hard drive, mobile email, etc. It is an infrastructure for urban informatization and modernization, and is also an important symbol for measuring the city's operating efficiency, informatization degree and competition level.

[Edit this paragraph] Common applications

New life in the wireless world information age Wireless public *** access: no longer restricted by cables and network interfaces, as long as there is wireless With network signal, you can use portable computers, mobile phones, and PDAs to surf the Internet, browse news, search for information, conduct QQ chat, send and receive emails, and send documents, photos, and other files anytime and anywhere. Wireless video service: Watch live TV/rebroadcasts and hold video conferences on your mobile phone, even in the car; use your mobile phone to chat with relatives and friends, listening to their voices and seeing them; you can see your children through "Home-School Communication" Safety and discipline at home and at school. Wireless location service: A family goes to the park and a child accidentally gets lost. If the child is equipped with a wireless tag, the child's location can be determined immediately through the wireless network positioning function, eliminating the need to worry about running around to find and broadcast the missing person; the driver can use the car's After the device is connected to the Internet and logged in, the wireless system can automatically detect whether the car has entered a dense traffic area. Wireless payment: During the peak passenger flow period represented by Spring Festival travel, there are long queues and overcrowding when purchasing tickets. The establishment of temporary sales points in conjunction with special vehicles for mobile ticketing will greatly ease the pressure on ticketing. Wireless cities make mobile ticketing a reality. Let ticket sales go to campuses, communities, and every corner of the city. Wireless network hard drive: With high-speed wireless networks, tourists and journalists no longer have to worry about the limited storage space of digital cameras and photo transfer. Once tourists finish taking pictures, they can immediately transfer them to the network hard drive through the wireless network. As long as the network hard drive is large enough, the number of photos can be increased infinitely; journalists can transfer them to the editorial department through the network after taking pictures. In addition, the construction of wireless cities also provides a platform for government departments and medical units to efficiently and collaboratively handle social emergencies. For example, when major safety incidents such as major fires and gas leaks occur, fire fighters and technical personnel will be dispatched. Rush to the scene quickly, and on the other hand, the scene situation can be restored to the city emergency command center through the camera system installed on the mobile vehicle, allowing the commander to make intuitive judgments and correctly issue rescue instructions to minimize losses; when critically ill patients are sent to the hospital On the way, body-worn or vehicle-mounted cameras and various sensors can be used to promptly transmit the patient's condition and physiological data back to the hospital in real time, gaining valuable time for the rescue of the injured patient.

[Edit this paragraph] Development Trend

In July 2004, Philadelphia in the United States proposed for the first time the construction of a Mesh network based on the Wi-Fi 802.11b standard, also called the "Wireless Philadelphia Plan." Subsequently, this wave of wireless city construction began to sweep across the world. As of December 2006, more than 400 cities had begun or planned to build wireless broadband metropolitan area networks to meet the needs of public access, public security and public security. The number of services has now reached 600. These cities include Washington, New York, San Francisco, Los Angeles, Portland, Philadelphia, Miami, and Orlando in the United States, London in the United Kingdom, Ontario in Canada, Perth in Australia, Wellington in New Zealand, Amsterdam in the Netherlands, Hamburg in Germany, and Israel Jerusalem, Singapore, Hong Kong, Taipei, etc. in China. Now, this wave has also begun to spread to mainland China, with cities such as Beijing, Tianjin, Shanghai, and Guangzhou beginning to consider building similar projects. The Tianjin Municipal Government will take the lead in building a wireless broadband coverage network in Binhai New Area and "pilot first" in the construction of wireless cities. Shanghai's construction plan will start from Jiading New Town, focusing mainly on municipal services. Jiading New Town uses wireless broadband network to provide full coverage in the new town, and uses a ubiquitous comprehensive wireless information network platform to support information applications such as public security, urban management, emergency linkage, public services, business tourism, and life and learning.

[Edit this paragraph] Four representative operating models

First, the ISP (Internet Service Provider) model. The government commissions network construction, and ISPs (including traditional operators) build and operate wireless urban networks by themselves or in cooperation with the government, and then wholesale and retail services to users, enterprises, and governments. Second, the advertising model. ISPs mainly build and operate their own networks, provide free, low-bandwidth services to ordinary citizens, and support free services through advertising. In addition, ISPs also wholesale access services with higher bandwidth, higher service quality, and no advertising to government departments, enterprises and groups. Third, the government-owned model.

From investment, network construction to network maintenance and operation, the government is mainly responsible for directly providing services to various city departments and citizens. Fourth, the cooperative model. All people or institutions that own Wi-Fi (Wireless Compatibility Certification) AP (Access Point) equipment and broadband access resources open their own resources through joining, so that public and privately owned decentralized Wi-Fi -Fi networks are connected together to form a virtual "wireless community".

[Edit this paragraph] Wireless City Case

The "Wireless City" plan has been developed globally for 10 years, but there are very few cases that can serve as samples. Wireless city projects in some countries have not been launched at all after large-scale publicity. Some cities represented by Houston, San Francisco, and Chicago have announced the suspension of their own wireless city networking plans. Many famous Wi-Fi startups such as Jolt-age, Cometa and others even fell into the desperate situation of bankruptcy. Taipei City's Wireless City Network (WIFLY) is very unique in the world. The first is that the population coverage rate reaches 90%, the second is that the design is integrated with the developing Wi-Fi, and the third is that the municipal government did not invest, but indirectly intervened by giving the winning team the operating rights through bidding, Anyuan Information The company is currently one of the major construction companies approved. The municipal government plays three roles in project promotion. First, it is a policy communicator. The government lets citizens know why the government wants to promote this plan through promotion and publicity; second, the government cooperates with Anyuan Company to jointly create Taipei Wireless City, on the other hand, allows citizens to understand the construction progress of the entire project; third, it will provide more government services based on the wireless city. The WIFLY project is divided into three phases. In the first phase, 30 subway stations and city halls were completed in a relatively short period of time, as well as the network construction within a 150-meter radius of the above-mentioned areas. The second phase was from the end of 2004 to the end of 2005, and was completed in the core areas of Taipei City, where the population density is relatively high. The third phase covers other areas of Taipei City, and finally reached a coverage rate of 90%. At present, e-bus services have been launched based on wireless cities, and services such as police patrols and electronic parking fee management will soon be launched. In terms of operations, Anyuan Company regards WIFLY as its own business, designing different prices for different needs and bundling them with related services. For example, many pda mobile phones, psp game consoles, etc. require network services, but the cost of accessing the Internet through 3G is too high , Anyuan Company bundles these services with wireless city networks. In addition to basic network access services, it will also tend to launch more services in the future, such as middleware services, including WIFLY network access, authentication, processing of multiple CPE platforms, and its own Business within the sales channel.

[Edit this paragraph] China’s Wireless City Plan

Twelve major cities in mainland my country have clearly defined wireless city plans and are under construction. These twelve major cities are Beijing, Tianjin, Qingdao, Wuhan, Shanghai, Nanjing, Hangzhou, Guangzhou, Shenzhen, Yangzhou, Chengdu, Luoyang. Zhuang Zixin calls them "several representative wireless cities". In fact, there are more in our country Cities such as Nanjing, Hong Kong and Taipei are all implementing wireless coverage. In summary, it includes three municipalities: Beijing, Tianjin, and Shanghai; it includes five provincial capital cities: Nanjing, Hangzhou, Guangzhou, Wuhan, and Chengdu; and it also includes three influential cities: Qingdao, Yangzhou, and Shenzhen. From a geographical perspective, these 11 cities include the Bohai Rim: Beijing, Tianjin, and Qingdao; the Yangtze River Delta: Shanghai, Hangzhou, and Yangzhou; and the Pearl River Delta: Guangzhou and Shenzhen. These cities basically belong to the economically developed areas on the southeast coast of my country. With the issuance of 3G licenses, wireless city plans have increasingly been put on the agenda of central cities in various regions. Its huge economic value has also been valued by many companies, and has gradually become the main force in wireless city construction, such as Changsha, Suzhou, Lhasa, Cities such as Lanzhou are evenly matched.

[Edit this paragraph] Wireless City-Wireless Life

"Wireless City": The only limit is imagination. For Jiading people living in "Wireless City", wireless In addition to making life more convenient, the Internet also provides more room for imagination. On June 25, the first phase of Beijing's "Wireless City" network began trial operation, and the news that "services will be provided to the public for free during the Olympics" is surprising. Coincidentally, a month ago, the first phase of the "Wireless City" project in Jiading, Shanghai was completed and opened. It covers an area of ??about 40 square kilometers and covers the central political, economic and cultural area of ??Jiading. For Zhejiang people, sitting by the West Lake, drinking tea and surfing the Internet will soon become a reality. Hangzhou's wireless broadband coverage backbone network is expected to be completed by the end of July. When the concept of "wireless city" breaks through the field of communication technology and becomes an important indicator to measure the level of urban modernization, what impact will it have on social development? We invited four people from different fields to talk about the present of wireless cities and imagine the future it will change. Life has changed as a result. Jiading citizens enjoy "wireless life". As soon as the car drives into the Jiading entrance of the Shanghai-Jiading Expressway, the WiFi signal will jump on the laptop screen as promised. The name of the network connection is "Wicity", and the computer shows that it is a "Wicity" "Unsecured network", that is, a free wireless network that anyone can log into. After the first phase of Jiading's "Wireless City" was opened, several friends immediately came to a coffee bar on Xincheng Road Street.

Turn on the laptop equipped with a wireless network card and start reading news and listening to music. The speed is not bad, and it is almost the same as using wired broadband at home. I heard that Jiading has become the first "wireless city" pilot project in mainland China. The question most frequently asked by friends from out of town is: Can you save on your annual Internet fees? If I send you an email, can you reply immediately even if you are outside? This also reflects from one side that everyone has a strong demand for low-cost, safe, and stable wireless networks. Within the coverage of wireless signals, we can access the Internet anytime and anywhere to receive emails, browse information, listen to music, watch movies, upload photos, etc. The biggest feeling it brings us is of course convenience. Especially when you go out, you no longer have to worry about finding network cables, interfaces, and Internet cafes to send emails or transfer documents. At present, Jiading's wireless services are mainly for business, and are covered in places where enterprises and institutions are concentrated, as well as in business buildings. It is foreseeable that after the "wireless city" is truly built, ambulances can obtain and transmit medical history and medical records in a timely manner while rescuing patients, and book surgeries, gaining valuable time for treating patients. Even farmers growing grapes in Jiading can easily monitor pests and diseases through wireless sensors, and transmit crop images directly to the research institute for remote diagnosis and guidance by experts.

[Edit this paragraph] Wireless City-Smart Community

Looking further afield, if the technology is mature enough, wireless smart communities will also become a reality. On a hot summer day, when you are driving home, you can use your mobile phone to make a call to turn on the air conditioner at home in advance, ask the juicer to prepare a cup of fresh juice, and then ask the home stereo to prepare your favorite Bach... In lazy winter, while you are lying on the sofa in the living room, you can use a remote control to let the coffee machine in the kitchen brew a pot of hot coffee, let the microwave oven prepare a delicious dinner for you, and then remotely control the printer in the study next door. You print out the documents needed for tomorrow's meeting... There are no nervous security guards in the community anymore. If someone's gas leaks, a fire breaks out, or someone breaks in, they have been automatically and timely reported to the community's alarm server. You no longer have to panic when you go to work, because the security guard of the community has already called you to tell you what the situation is like... Of course, before starting to use it in residents' residences, the problem of how to coordinate wireless and wired operators needs to be solved. If we want to truly achieve city-wide coverage, the implementation of funds, management, and human resources are all issues that need to be solved one after another. From this perspective, "wireless city", as a public service facility provided by the government, also promotes the transformation of public service concepts: in more and more fields, the government has begun to provide services to citizens. The phenomenon of paying the bill is a manifestation of urban civilization. Wireless cities are not a dream. In China, cities such as Beijing, Tianjin, and Hangzhou have joined in. Get the information you need anytime, anywhere. Public information will be more transparent. Narrator: Zheng Xiaolin, deputy general manager of Hangzhou Wasu Digital TV Co., Ltd. Just install a small chip - a wireless communication module, which can replace the knives, interfaces and wiring required for wired networks. Wireless cities will provide a cleaner and more convenient living space. The so-called wireless city means that a variety of terminals can access wireless broadband networks at any place, at any time in the city, and all applications of the wired Internet can be realized in a wireless state. Hangzhou's wireless coverage backbone network will be ready by the end of July this year, and systematic wireless services will be launched one after another after July. By the end of next year, Hangzhou is expected to become the first "wireless city" among provincial capitals in the country. Just as mobile phones get rid of the shackles of telephone lines, wireless broadband can free us from dependence on network wires for surfing the Internet. Wireless network technology makes the computer a roaming medium or mobile library, and you will be able to obtain the information you need anytime and anywhere. The entertainment projects for citizens will be more abundant. Using handheld terminals, you can watch movies, watch TV, and play online games... Photos taken with your mobile phone can be instantly sent to relatives and friends on the other end of the network. As soon as foreign tourists enter Hangzhou city, they will feel "at home" in terms of information technology. As long as you rent a wireless terminal, there will be voice prompts to guide tourists, explain scenic spots, and provide relevant information. Business travelers only need to purchase a wireless service card to obtain timely information and conduct e-commerce transactions anytime and anywhere. In the near future, the application of wireless broadband can also help the public security department catch fugitives and help the environmental protection department monitor corporate leakage and discharge problems. An important application of wireless broadband is the informatization of public security. In the future, governments, units, and communities can realize multiple functions such as news browsing, online information inquiry, city public service information and emergency information release, visual communication, and wireless voice communication through wireless Internet access. At the same time, public service projects such as road monitoring, traffic management, safety monitoring, environmental data collection, and hydrological monitoring will gradually become "wireless". All kinds of information within the city will be quickly delivered to various departments, and public information will be Be more transparent. For example, Hangzhou’s new parking policy that started on July 1 uses wireless POSE machines to manage vehicle charges. The use of parking space wireless guidance system allows drivers to see where there are empty parking spaces through handheld terminals. Traffic guidance systems allow drivers to avoid congested roads. It can be seen that the realization of "wireless city", in addition to providing convenience to citizens, is of great significance for improving the management level and efficiency of the city and improving the modernization level of the city.

"Wireless city" represents the direction of future urban informatization. We may do better than foreign countries in breaking through the "Philadelphia model".

[Edit this paragraph] Wireless City-Wireless Extension

The surrounding areas of Beijing, Shanghai and Guangdong are competing for the wireless city construction plan to be promoted. On June 25, an article "Beijing opens wireless Internet access in urban areas" "The news has aroused great concern, and a reporter from China Times learned that while "Beijing is building a wireless city," Shanghai, Guangzhou and even the Yangtze River Delta and Pearl River Delta are launching wireless city construction plans, which may lead to these cities The wireless network has undergone tremendous changes, and it will also have a profound impact on the current competitive landscape of the telecommunications industry. Beijing, Shanghai and Guangdong compete for wireless city plan "From now on, Beijing will be able to achieve wireless Internet access within the urban area, including the second ring road, third ring road, CBD business district, Financial Street (000402, stock bar), Zhongguancun (000931, stock bar) area and Wangjing Economic and Technological Development Zone, Xuanwu Chunshu, Yizhuang area, etc., covering an area of ??about 100 square kilometers, Beijing will also become the largest wireless urban network in China. On the morning of June 25, it was called China’s largest 3.5. Guo Hongtao, Vice President of Beijing China Electronics Huatong Company of G Virtual Operator, announced this. Zhu Yan, who was present at the Beijing Municipal Information Office, also affirmed this in his speech. Obviously, there is no doubt about the authenticity of this "wireless city plan" that has attracted the attention of Beijing consumers. Wireless Internet access has always been an important issue that troubles mid- to high-end users. Although China Mobile, China Telecom and China Netcom have built WI-FI networks in many places in recent years, these WI-FI networks are always built in coffee shops, airports and other places and are expensive, making it difficult to meet demand. According to what a China Times reporter learned, in addition to Beijing, Shanghai and Guangzhou also planned to build wireless city projects at almost the same time. It is reported that on June 18, Guangzhou was consulting telecommunications experts for their opinions on building a wireless city. According to relevant experts, not only Guangzhou will be built into a wireless city as soon as 2010, but the entire Pearl River Delta will also be included in the scope of wireless city construction. Shanghai announced on June 13 that the first phase of the wireless broadband network project in Xuhui District has been officially launched recently. This is the first area in Shanghai's central urban area to achieve "wide coverage of wireless networks." Obviously, Beijing, Shanghai and Guangdong are all scrambling for wireless city construction plans. Will be extended to surrounding areas. Tariff is the most concerned issue for users. "It will be free during the initial Olympic period, and users will be charged after the Olympics." On June 23, Guo Hongtao, vice president of China Electronics Huatong, said. According to CEC Huatong's plan, after the Olympics, the wireless Internet tariff in Beijing will cost 0.12 yuan per minute if you do not choose several packages. This price is still lower than existing WI-FI networks, so it is still competitive. Another issue that has attracted industry attention is coverage. Regarding this point, Guo Hongtao said: "The first phase of coverage has been completed as planned. The second phase will complete 625 square kilometers of urban coverage within the Fifth Ring Road by the end of 2009, popularizing wireless broadband high-speed Internet access, and the technology has been applied in Chongwen District Trials have begun in several locations such as the New World (600628, Stock Bar) business district; by the end of 2010, the third phase will achieve wireless broadband network coverage in urban and rural areas of Beijing. "Guangzhou is not showing weakness," said an expert from the China Mobile Communications Federation. It was revealed: "Guangzhou plans to build a wireless city within 2 to 3 years. It will first be piloted in several districts such as Luogang and Nansha, and then promoted to the Pearl River Delta." The construction of Shanghai's "wireless city" project has also made substantial progress. It is reported that there are currently 2,500 wireless coverage sites in Shanghai. It is expected that by the end of this year, wireless broadband coverage will be achieved in the city's main business districts and densely populated areas. Fighting for operating qualifications Behind the scenes of the "Wireless City" project, fighting for operating qualifications has also become the focus. It is reported that CEC Huatong is a state-owned enterprise founded in January 2003 with a registered capital of 2 billion yuan. At the beginning of its establishment, it won the Ministry of Information Industry’s right to operate the 3.5GHz frequency band in five cities, and subsequently owned The right to use the 3.5GHz terrestrial fixed wireless access system frequency in 29 cities including Beijing, Shanghai, Chongqing, and Qingdao. In fact, in Beijing, CEC Huatong obtained the construction rights of the "Wireless City" plan, which made Beijing Netcom very embarrassed. In Guangzhou, China Electronics Huatong currently also wants to participate in the construction of the Guangzhou Wireless City Plan. However, Guangzhou Telecom and Guangzhou Mobile are also competing for operating qualifications. But in Shanghai, the operating entity has long been identified and has been acquired by China Telecom Shanghai Company. Shanghai Telecom has currently signed a "Wireless City" cooperation agreement with 17 districts and counties in Shanghai. “The rise of 3.5G virtual operators like China Electronics Huatong is a great threat to basic telecom operators and will seize the market share of basic telecom operators in wireless Internet access, but the key lies in 3.5G virtual operations. Whether operators have sufficient financial strength to complete network construction, only if they have certain financial resources can they compete with basic telecom operators," an industry insider believes.
