[Edit this paragraph] Common applications
Wireless access to the new life of the wireless world in the information age: it is no longer limited by cables and network interfaces. As long as there is wireless network signal, you can surf the Internet, browse news, search materials, chat on QQ, send and receive emails, and transmit documents such as manuscripts and photos anytime and anywhere. Wireless video service: watch live TV/radio and hold video conference on mobile phone or even in the car; Chatting with friends and relatives by mobile phone, not only listening to their voices, but also seeing their people; Through "home-school communication", we can see whether children are safe and disciplined at home and school. Wireless location service: A family went to the park, and the child got lost accidentally. If equipped with a wireless list, the child's position can be determined immediately through the wireless network positioning function, thus avoiding the anxiety of running around looking for people and broadcasting them; After the driver logs in with the on-board device, the wireless system can automatically perceive whether the car has entered a traffic-intensive area. Wireless payment: During the peak passenger flow period represented by Spring Festival travel rush Peak, there is a phenomenon of long queues and overcrowding for passengers to purchase tickets. The establishment of temporary sales outlets and mobile ticket sales vehicles will greatly ease the pressure on ticket sales. Wireless city will make mobile ticket sales a reality and make ticket sales go to every corner of campus, community and city. Wireless network hard disk: With high-speed wireless network, tourists and journalists no longer worry about the limited storage space of digital cameras and photo transmission. Once the tourists have finished shooting, they can immediately transfer it to the network hard disk through the wireless network. As long as the network hard disk is large enough, the number of photos can be increased indefinitely. Reporters can send it to the editorial department through the internet after shooting. In addition, the construction of wireless city also provides a platform for government departments and medical units to respond to social emergencies efficiently and cooperatively. For example, when a major fire, gas leakage and other major safety accidents occur, on the one hand, firefighters and technicians are dispatched to the scene, on the other hand, the scene can be restored to the urban emergency command center through the camera system installed on the mobile car, so that the commander can make intuitive judgments and correctly issue rescue instructions to minimize losses; After critically ill patients are sent to the hospital, they can send the information and physiological data of the injured back to the hospital in real time through portable or vehicle-mounted cameras and various sensors, thus winning valuable time for the rescue of the injured.
[Edit this paragraph] Development trend
In July 2004, Philadelphia first proposed to build a mesh network based on Wi- Fi 802. 1 1b standard, also known as the "Wireless Philadelphia Plan". Then this wave of wireless city construction began to sweep the world. By the end of June, 2006, 5438+February, more than 400 cities have started or planned to build wireless broadband metropolitan area networks to meet the needs of public access, public safety and public services, and the number has reached 600 at present. These cities include Washington, new york, San Francisco, Los Angeles, Portland, Philadelphia, Miami, Orlando, London, Ontario, Australia, Wellington, New Zealand, Amsterdam, Hamburg, Israel, Jerusalem, Singapore, Hong Kong and China Taipei. Now, this wave has also begun to spread to Chinese mainland, and cities such as Beijing, Tianjin, Shanghai and Guangzhou have also begun to consider building similar projects. Tianjin Municipal Government will take the lead in building a wireless broadband coverage network in Binhai New Area, and "try first" in the construction of wireless cities. Shanghai's construction planning will start from Jiading New Town, mainly focusing on municipal services. Jiading New Town adopts wireless broadband network to fully cover the new urban area, and supports information applications such as public security, urban management, emergency response, public services, business travel, life and study with the ubiquitous comprehensive wireless information network platform.
[Edit this paragraph] Four representative operation modes
First, ISP (Internet Service Provider) mode. The government entrusts the construction of the network, and ISP (including traditional operators) builds and operates the wireless city network by themselves or in cooperation with the government, and then wholesales and retails the business to users, enterprises and the government. Second, the advertising model. ISP mainly builds and operates its own network, provides free low-bandwidth services for ordinary citizens, and supports free services through advertisements. In addition, ISP also wholesales high-bandwidth, high-quality service and advertisement-free access services to government departments, enterprises and organizations. Third, the only model of government. From investment, network construction to network maintenance and operation, the government is mainly responsible for providing services directly to various departments and citizens in the city. Fourth, the mode of cooperation. All people or institutions with Wi-Fi (wireless compatibility certification) AP (access point) equipment and broadband access resources open their own resources by joining, connecting public and private scattered Wi-Fi networks to form a virtual "wireless community".
[Edit this paragraph] Wireless City Case
The "Wireless City" plan has been developed worldwide for 10 years, and there are few cases that can be used as samples. In some countries, wireless city projects have not started at all after large-scale publicity. Some cities, such as Houston, San Francisco and Chicago, announced the suspension of wireless city networking plans, and many popular Wi-Fi startups, such as Jolt-age and Cometa, even went bankrupt. Taipei's wife is very distinctive in the world. First, the population coverage rate reached 90%; The second is the combination of design and developing Wi-Fi; Third, the municipal government did not contribute, but indirectly intervened by bidding for the right to operate the winning team. Anyuan Information Company is one of the main contractors currently approved. The municipal government plays three roles in promoting the project. First, it is a policy disseminator, and the government lets the public know why the government wants to promote this plan through publicity. Second, through the cooperation with Anyuan Company, on the one hand, the government will build a wireless city in Taipei, on the other hand, the public will know the construction progress of the whole project; Third, wireless cities will provide more government services. The WIFLY project is divided into three stages. In the first stage, the network construction of 30 subway stations and town halls and within the radius of150m in the above areas will be completed in a short time. The second stage, from the end of 2004 to the end of 2005, completed the core area of Taipei, which is a place with relatively high population density. The third phase is the other areas of Taipei, and finally it reaches 90% coverage. At present, e-bus service has been launched in wireless cities, and services such as police patrol and electronic parking charge management will also be launched soon. In operation, Anyuan takes WIFLY as its own business, designs different prices according to different needs, and bundles them with related services. For example, many pda phones and psp game consoles need network services. However, if the cost of accessing the Internet through 3G is too high, Anyuan Company will bundle these services with the wireless city network. In addition to basic network access services, Anyuan Company will tend to introduce more services in the future, such as middleware services, including wifi access to the network, authentication, handling various CPE platforms and itself.
[Edit this paragraph] China's wireless city plan
Two major cities in Chinese mainland, 12, have defined their wireless city plans and are currently under construction. The twelve major cities are Beijing, Tianjin, Qingdao, Wuhan, Shanghai, Nanjing, Hangzhou, Guangzhou, Shenzhen, Yangzhou, Chengdu and Luoyang. Zhuang is called "a group of representative wireless cities". In fact, more cities in China, such as Nanjing, Hongkong and Taibei, are realizing wireless coverage. To sum up, it includes three municipalities directly under the central government, namely Beijing, Tianjin and Shanghai, and five capital cities, namely Nanjing, Hangzhou, Guangzhou, Wuhan and Chengdu. It also includes three influential cities: Qingdao, Yangzhou and Shenzhen. This 1 1 city is geographically around the Bohai Sea: Beijing, Tianjin and Qingdao; Yangtze River Delta: Shanghai, Hangzhou and Yangzhou; Pearl River Delta: Guangzhou and Shenzhen. These cities basically belong to the southeast coastal areas with relatively developed economy in China. With the issuance of 3G licenses, wireless city planning is increasingly put on the agenda of regional central cities, and its huge economic value is also valued by many enterprises, and it has gradually become the main force of wireless city construction, such as Changsha, Suzhou, Lhasa, Lanzhou and other cities.
[Edit this paragraph] Wireless City-Wireless Life
"Wireless City": The only limitation is imagination. For Jiading people living in "wireless city", wireless network not only brings more convenient life, but also gives them more space to daydream. On June 25th, the first phase of Beijing's "Wireless [1] City" network began trial operation, and the news that "free services will be provided to the society during the Olympic Games" was surprising. Coincidentally, a month ago, the first phase of Shanghai Jiading Wireless City was completed and opened, covering an area of about 40 square kilometers, covering the political, economic and cultural center of Jiading. For Zhejiang people, it will soon become a reality to sit by the West Lake and surf the Internet while drinking tea. Hangzhou 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 current situation of wireless city and imagine the future it has changed. Therefore, people in Jiading enjoy a "wireless life". As soon as the car enters the Jiading entrance of Hu Jia Expressway, the WiFi signal will jump to the laptop screen as scheduled. The name of the network connection is "Wicity", and the computer shows that this is an "unsecured network", that is, this is a free wireless network, and everyone can log in. After the opening of the first phase of Jiading Wireless City, several friends came to a coffee bar in Xincheng Road Street for the first time. Turn on the laptop with wireless network card, and start watching news and listening to music. The speed is not bad, just like using wired broadband at home. It is reported that Jiading has become the first "wireless city" pilot in Chinese mainland. The most frequently asked question by friends from other places is: Can you save the annual Internet access fee? If I send you an email, can I reply immediately even if you are outside? This also reflects from one side that people have a strong demand for low-cost, safe and stable wireless networks. Within the coverage of wireless signals, we can receive emails, browse information, listen to music, watch movies and upload photos online. Anytime and anywhere, of course, this brings us the greatest feeling. Especially when you are away from home, you don't have to worry about sending emails or manuscripts, looking for network cables, looking for interfaces and looking for Internet cafes. At present, the wireless service in Jiading is mainly business, and it has been covered in places where enterprises and institutions are concentrated and commercial buildings. It can be predicted that after the "wireless city" is really completed, ambulances can obtain and transmit medical history and medical records in time on the way to rescue patients, and make an appointment for surgery, thus winning valuable time for treating patients. Even farmers who grow grapes in Jiading can monitor diseases and pests conveniently through wireless sensors, and send crop images directly to the research institute for remote diagnosis and guidance by experts.
[Edit this paragraph] Wireless City-Wireless City
Looking further ahead, if the technology is mature enough, wireless wireless cities will also become a reality. In hot summer, when you are driving home, you can turn on the air conditioner at home by making a phone call with your mobile phone, let the juicer prepare a cup of freshly squeezed juice, and then let the stereo at home prepare your favorite Bach ... In lazy winter, lying on the sofa in the living room, you can let the coffee machine in the kitchen make a pot of hot coffee through the remote control and let the microwave oven prepare a delicious dinner for you. Then remotely control the printer in the study next door to print the documents needed for tomorrow's meeting ... there are no nervous security guards in the community anymore. All gas leaks, fires and intruders have been automatically notified to the alarm server in the community in time, so you don't have to worry when you go to work, because the security guards in the community have already called you for the first time ... Of course, before the residential buildings are used, how to coordinate the wireless and wired operators needs to be solved. If we really want to achieve urban coverage, the implementation of funds, management and human resources are all problems that need to be solved one after another. From this point of view, "wireless city", as a public facility provided by the government, has also promoted the change of public service concept: in more and more fields, the phenomenon that the government pays for citizens' lives has begun to appear, which is a manifestation of urban civilization. Wireless city is not a dream. In China, Beijing, Tianjin, Hangzhou and other cities have also joined in. It will be more transparent to get the information you need anytime and anywhere. Narrator: Zheng Xiaolin, deputy general manager of Hangzhou Huashu Digital TV Co., Ltd., has just installed a small chip-wireless communication module, which can replace the knives, interfaces and wiring required by wired networks. Wireless city will provide a cleaner and more convenient living space. The so-called wireless city means that all kinds of terminals can access the wireless broadband network at any place and at any time in the city, and all applications of wired Internet can be realized in the wireless state. The backbone network of wireless coverage in Hangzhou can be completed 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 the provincial capital cities in China. Just as mobile phones get rid of the shackles of telephone lines, wireless broadband can make us get rid of the dependence on internet cables. Wireless network technology makes the computer a roaming medium or a mobile library, and you will be able to get the information you need anytime and anywhere. Citizens' entertainment projects will be more abundant. With a handheld terminal, you can watch movies, watch TV and play online games ... The photos taken with your mobile phone can be immediately sent to friends and relatives at the other end of the network. As soon as foreign tourists enter Hangzhou, they will feel "at home" in informatization. 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 can get information and conduct e-commerce transactions anytime and anywhere by purchasing wireless service cards. In the near future, the application of wireless broadband can also help the public security department to catch fugitives and help the environmental protection department to monitor the tax evasion of enterprises. An important application of wireless broadband is public information. In the future, the government, units and communities can realize news browsing, online information inquiry, urban public information and emergency information release, visual communication, wireless voice communication and other functions through wireless Internet access. At the same time, public services such as road monitoring, traffic management, safety monitoring, environmental data collection and hydrological monitoring will be gradually "wireless", and all kinds of information within the city will be quickly delivered to various departments, and public information will be more transparent. For example, Hangzhou's new parking policy, which started in July 1, is to use wireless POSE machines to manage vehicle charges. With the use of wireless parking guidance system, drivers can see where there are empty parking spaces through handheld terminals. The traffic guidance system enables drivers to avoid crowded roads. It can be seen that the realization of "wireless city" is of great significance not only for the convenience of citizens, but also for improving the management level and efficiency of the city and the modernization level of the city. "Wireless City" represents the future direction of urban informatization. Breaking through the Philadelphia model, we may do better than foreign countries.
[Edit this paragraph] Wireless City-Wireless Extension
The wireless city construction plans in Beijing, Shanghai and Guangdong will be promoted in the surrounding areas. On June 25th, a news that "Beijing has opened wireless Internet access in urban areas" caused great concern. The reporter of China Times learned that while "Beijing is building a wireless city", Shanghai, Guangzhou, the Yangtze River Delta and the Pearl River Delta are all launching wireless city construction plans, which will probably lead to great changes in the wireless networks of these cities, and will also have a far-reaching impact on the current competitive landscape of the telecommunications industry. Beijing-Shanghai-Guangdong Wireless City Plan "From now on, the urban area of Beijing will have wireless Internet access, including Second Ring Road, Third Ring Road, CBD Business District, Financial Street (000402, Guba), Zhongguancun (00093 1, Guba), Wangjing Economic and Technological Development Zone, Xuanwu Toon and Yizhuang, with an area of about 65438. On the morning of June 25th, Guo Hongtao, vice president of Beijing CLP Huatong Company, known as the largest 3.5G virtual operator in China, announced the news. Zhu Yan, director of the Beijing Office at that time, also affirmed this point in his speech. Obviously, there is no doubt about the authenticity of this "wireless city plan" that attracts the attention of Beijing consumers. Wireless Internet access has always been an important problem that puzzles middle and 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 cafes, airports and other places, and the cost is too high to meet the demand. According to the reporter of China Times, besides Beijing, Shanghai and Guangzhou also plan to build wireless city projects almost at the same time. It is reported that on June 18, Guangzhou is consulting telecom experts on building a wireless city. According to experts, not only Guangzhou will be built into a wireless city in 20 10 at the earliest, but the whole Pearl River Delta will also be included in the scope of wireless city construction. Shanghai, on the other hand, announced on June 13 that the first phase of the wireless broadband network project in Xuhui District was officially opened recently, which is the first area in the central city of Shanghai to achieve "wide coverage of wireless networks". Obviously, Beijing, Shanghai and Guangdong are all vying for the wireless city construction plan. The tariffs that will be extended to the surrounding areas are what users are most concerned about. " Free at the beginning of the Olympic Games, and users will be charged after the Olympic Games. "On June 23rd, Guo Hongtao, vice president of CLP Huatong, said. According to CLP Huatong's plan, after the Olympic Games, if you don't choose several packages, you will charge 0. 12 yuan per minute for wireless Internet access in Beijing. This price is still lower than the existing WI-FI network, so it is still competitive. Another issue that has attracted the attention of the industry is coverage. In this regard, Guo Hongtao said: "At present, the first phase of coverage has been completed as planned. In the second stage, by the end of 2009, it will cover 625 square kilometers of urban areas within the Fifth Ring Road and popularize wireless broadband high-speed Internet access. The application of this technology has been tested in many places such as New World (600628, Guba) business district in Chongwen District. By the end of 20 10, the third phase will realize the coverage of urban and rural wireless broadband networks in Beijing. "Guangzhou does not show weakness. An expert from China Mobile Communications Association revealed: "Guangzhou plans to build a wireless city in two to three years. It will be piloted in Luogang, Nansha and other districts first, and then extended to the Pearl River Delta. "Shanghai's' wireless city' project construction has also made substantial progress. It is reported that there are currently 2,500 wireless coverage sites in Shanghai. It is estimated that by the end of this year, the main business districts and densely populated areas in the city will achieve wireless broadband coverage. Grab the operation qualification behind the scenes of the "wireless city" project, and grab the operation qualification has also become the focus. It is reported that CLP Huatong is a state-owned enterprise. Founded in June 5438 +2003 10, with a registered capital of 2 billion yuan. At the beginning of its establishment, it obtained the right to use the 3.5GHz frequency band operated by the Ministry of Information Industry in five cities, and then obtained the right to use the 3.5GHz terrestrial fixed wireless access system in 29 cities including Beijing, Shanghai, Chongqing and Qingdao. In fact, in Beijing, CLP Huatong won the right to build a "wireless city" plan, which made Beijing Netcom very embarrassed. In Guangzhou, at present, CLP Huatong also wants to participate in the construction of Guangzhou wireless city plan. However, Guangzhou Telecom and Guangzhou Mobile compete with them for operating qualifications. However, in Shanghai, the operating entity has long been clear, and it was acquired by China Telecom Shanghai Company. At present, Shanghai Telecom has signed a "wireless city" cooperation agreement with Shanghai 17 districts and counties. " The rise of 3.5G virtual operator, like CLP Huatong, is a great threat to basic telecom operators, which will seize the market share of basic telecom operators in wireless Internet access, but the key depends on whether 3.5G virtual operator has enough financial strength to complete the network construction. With certain financial resources, we can compete with basic telecom operators. "An insider thinks so.
